2. Description of Related Art
In entering into the twenty-first century, Internet business or e-commerce has become one of the largest industries and continues its growth exponentially. Many people's daily lives are closely related to the Internet business and are significantly impacted by the Internet technology's evolution and revolution. More and more people have used the Internet and even accessed/browsed the Internet in their daily lives, whether for work, entertainment, shopping, or education, etc. The Internet is creating a new economy, which is competing with people's traditional way of living.
Like many other new technology, Internet technology is facing many challenges and problems, particularly when Internet technology is penetrating into the general public. One of the main problems is that Internet accessing/browsing often requires one to know how to use a personal computer. At present, still the majority of the general public is not computer literate or may not care to be computer literate. Many people have found that a personal computer is clumsy, expensive to maintain and/or upgrade, and often not reliable. As a result, many people still avoid using a personal computer.
Further, even if one uses a personal computer, to access/browse the Internet is often problematic. For example, the Internet connection between a computer and Internet providers is often denied during a peak time, and the Internet connection is generally very slow in uploading/downloading Internet information. People have to pay much more monthly fees to obtain a relatively higher speed access to the Internet. Such fees put the access to the Internet out of reach of most people.
In addition, a personal computer is usually used for a lot of different applications, such as word processing, imaging designing, networking, email, Internet accessing/browsing web sites, etc. These applications and the computer itself are co-existed and generally operated by a complicated software operating system, thereby significantly slowing down the operations of the applications. The more applications are operated by an operating system, the slower the operation speed is. This significantly slows down the performance of the Internet accessing/browsing. The operation overhead of most personal computers is not optimized for advanced Internet performance like streaming video or other high volume data transmission applications.
Also, a personal computer does not provide a comfortable setting for people to surf the Internet for entertainment, shopping, education, etc. As a result, many people, even if they own a personal computer, have been looking for other alternatives to access the Internet.
Some recent Internet technology has demonstrated its ability to access/browse the Internet without a personal computer by using new types of devices broadly called “information appliance”—essentially, they are digital gadgets of various sizes and shapes, which are dedicated to surfing the Internet. Some devices resemble cable TV boxes, and some others look like small laptops, mobile phones, etc. Some devices are used to surf the Internet and access e-mails, and some others are strictly used to surf the Internet. While people have saved money from buying a personal computer, they are forced to purchase as well as maintain a new line of “information appliance” for different purposes. Furthermore, these new devices are basically small sized computers for different specific purposes. However, many people still are not interested in buying a new device just to surf the Internet.
The general public is used to conventional devices, such as televisions, phones, etc. Also, the majority of the general public has already owned these conventional devices. They are easy to operate and relatively reliable in performance. Therefore, there is a desire for the general public to access/browse the Internet via these conventional devices without using a personal computer, or other hardware equipment, such as modem, “information appliance”, etc. Just like many people have quit buying an answering machine for storing phone messages—instead, using a “hardware-less” voice messaging service—, there is a need to have a “hardware-less” Internet service to access/browse the Internet via conventional televisions and phones.
Most of the homes or offices have recently been wired for cable broadcast, which may hook to a set top box and a cable ready television, or wired for a satellite receiver to receive multiple television channels. It is desirable to use the existing cable wiring or satellite receiver to receive Internet information. More importantly, cables or satellite channels have much wider bandwidth to serve the general public than phone lines which computers are generally connected to. It is desirable to use the existing wide band cable or satellite systems to receive volumetric Internet information, such as streaming video, etc.
Internet TVs were proposed several years ago. Internet TVs were proposed to provide people the possibility of obtaining Internet access at a location, such as at home, by using only a regular cable TV set and an easy-to-use control device, such as a phone. For example, a concept of a telephone remote-controlled cable television Internet was once introduced, in which button keys of a push button-type telephone at a cable television subscriber's end are used to simulate functions of a computer mouse or a computer keyboard to remote-control, via a telephone network, an Internet main unit at a cable television provider's end, so as to acquire Internet resources around the world.
However, the proposed Internet TVs are very primitive and immature. Due to the communication channel band limitation, the proposed Internet TVs cannot serve multiple users or a large amount of users at the same time. In addition, there are privacy or other security concerns, which have not been addressed, in the proposed Internet TVs. Further, the push button-type telephone interface is not user-friendly. People are not used to relate the button keys or their corresponding English letters on a telephone to the represented functions or modes. Also, different telephones may have a different arrangement for the button keys. These make surfing the Internet very time consuming and uncomfortable. Furthermore, the button keys on a telephone may malfunction after a period of use. Moreover, quite a few people are still using conventional rotary telephones, which do not have push button keys.
The Internet TVs were proposed to allow a user to surf the Internet on TV. However, the proposed Internet TVs mainly provide a bridge between the Internet URL sources and the cable TV systems by stream downloading whatever the URL sources present. Users may not very easily browse Internet contents to find what they are looking for because the stream-downloaded Internet contents are merely related to certain URL sources or destinations. Many users have wasted a lot of time in looking for URL sources and/or in browsing Internet contents. Users often desire assistance in an interactive manner to not only find a URL source for certain Internet contents, but also have a user-friendly interface to find the URL source and go through the Internet contents. Also, the users would often like to organize Internet contents in a specific fashion.
It is with respect to these or other considerations that the present invention has been made.
SUMMARY OF THE INVENTIONTo overcome the limitations in the prior art described above, and to overcome other limitations that will become apparent upon reading and understanding the present specification, the present invention discloses a telephone controlled cable or satellite television Internet system and method and remote computing service systems and methods.
The present invention solves the above-described problems by using a telephone interface and voice recognition driven Internet browser system and method for Internet accessing/browsing on a cable or satellite television. One of the cable or satellite channels is designated for the Internet accessing/browsing.
In one embodiment of the present invention, a system for accessing/browsing the Internet on a cable or satellite television, includes: a phone for receiving a voice signal from a user, the voice signal controlling an Internet interface which displays Internet content on the television via a cable or satellite channel; a voice recognizer, operated on a supercomputer or other computer platforms (e.g. CPU platforms), recognizing/interpreting/analyzing the voice signal and generating command signals to access/browse the Internet, the voice recognizer being capable of simultaneously recognizing voice signals transmitted from a plurality of users and generating command signals for accessing/browsing the Internet; and a stack of computers (or like devices optimized for Internet accessing/browsing) and an Internet browser, each of the stack of computers, based on the command signals from the voice recognizer, accessing/browsing the Internet and retrieving/organizing Internet content via the Internet browser, the Internet content being sent to the cable or satellite television via cable or satellite media.
Further in one embodiment of the present invention, the voice recognizer operated on the supercomputer or other computer platforms is disposed in a phone switching network. In another embodiment, the voice recognizer operated on the supercomputer or other computer platforms is disposed in a cable or satellite system. In a further embodiment, the voice recognizer can be installed in a phone or any other parts of the system.
Still in one embodiment of the present invention, the accessed, browsed, or organized Internet content is presented on the cable or satellite television and interactive with the user's voice signal.
Additional in one embodiment of the present invention, the cable or satellite television further includes a set top box/filter having identification. If an identification of the phone does not match with the identification of the set top box/filter, the Internet content is filtered out. If the identification of the phone matches with the identification of the set top box/filter, the Internet content is presented on the television.
Yet in one embodiment of the present invention, the cable or satellite television further includes a frame grabber device for locally refreshing the content of the Internet information presented on the television until a subsequent request being made by a user via the phone.
Yet in one embodiment of the present invention, the voice signal may include a plurality of instructions of accessing/browsing the Internet content, and/or a plurality of menu instructions, such as “go back” to the previous frame, “go to” the main page, etc.
Still in one embodiment of the present invention, the phone switching network is coupled to a plurality of users' phones for routing corresponding plurality of voice signals from the plurality of users to the voice recognizer for recognizing/interpreting/analyzing the corresponding voice signals and generating command signals to access/browse the Internet on the cable or satellite system. The system includes at least one Internet browser. The Internet browser can be run on a computer or a stack of computers, for accessing, browsing, and/or organizing Internet contents based on the command signals from the voice recognizer and presenting accessed, browsed, and/or organized Internet contents or user instructions from the cable or satellite system to the cable or satellite television.
In one embodiment of the present invention, a method of accessing/browsing the Internet via a cable or satellite television includes: receiving a voice signal from a user, the voice signal controlling an Internet interface which displays the Internet content on the cable or satellite television via a cable or satellite channel; routing the voice signal to a voice recognizer; recognizing/interpreting/analyzing the voice signal and generating command signals to access/browse the Internet contents on a cable or satellite system by a supercomputer, the voice recognizer being capable of simultaneously recognizing/interpreting/analyzing a plurality of voice signals transmitted from a plurality of users and generating the command signals for accessing/browsing the Internet; accessing, browsing, and/or organizing Internet contents based on the command signals from the voice recognizer; and presenting accessed, browsed, and/or organized Internet content from the cable or satellite system to the cable or satellite television via a cable or satellite channel or medium.
Additionally in one embodiment, the method further includes the step of receiving a second voice signal, which is interactive to the Internet content presented on the cable or satellite television.
Further in one embodiment of the present invention, the operation of the voice recognizer on the supercomputer is in the phone switching network. In an alternative embodiment, the operation of the voice recognizer on the supercomputer is in the cable or satellite system.
Still in one embodiment of the present invention, the method further includes the step of filtering out the signals received from the cable or satellite channel if an identification of the phone does not match with an identification of a filter, and passing through the signals if the identification of the phone matches with the identification of the filter.
Yet in one embodiment of the present invention, the method further includes the step of locally refreshing the content of the Internet information presented on the television until a subsequent request being made by a user via the phone.
Additionally in one embodiment of the present invention, the method further includes the step of downloading information, such as movies, music, or other services, etc., at a local site, e.g. at the set top box of the television or the like, for a user to make subsequent uses.
The present invention provides a system capable of uploading voice signals via a narrowband wire or medium, such as a phone line or a data port line (or referred to as the smaller wire), and downloading the Internet information via a broadband wire or medium, such as cables or satellite receiver (or referred to as the larger wire). The larger wire is well suited to receive a large amount of data efficiently. Accordingly, the present invention uses voice recognition to upload a request via a telephone wire and download the requested data via a cable or satellite channel.
One advantage of the present invention is that it provides a user friendly interface such that a user does not have to be a computer literate to access/browse the Internet. Also, a computer does not have to be maintained and/or upgraded on an individual user basis.
These and various other advantages and features of novelty which characterize the invention are pointed out with particularity in the claims annexed hereto and form a part hereof. However, for a better understanding of the invention, its advantages, and the objects obtained by its use, reference should be made to the drawings which form a further part hereof, and to accompanying descriptive matter, in which there are illustrated and described specific examples of an apparatus in accordance with the invention.
BRIEF DESCRIPTION OF THE DRAWINGSReferring now to the drawings in which like reference numbers represent corresponding parts throughout:
In the following description of the exemplary embodiment, reference is made to the accompanying drawings which form a part hereof, and in which it is shown by way of illustration the specific embodiment in which the invention may be practiced. It is to be understood that other embodiments may be utilized as structural changes may be made without departing from the scope of the present invention.
The present invention discloses a telephone controlled television Internet system and method and remote computing service systems and methods. The present invention uses a telephone interface and voice recognition driven Internet browser system and method for Internet accessing/browsing on a cable or satellite television.
It is appreciated that the present invention is not limited to an embodiment of an Internet TV system where a transmitting device is a telephone, and a receiving device is a television via a cable or satellite channel or medium. The present invention applies to many other embodiments and/or configurations of an Internet TV system where a transmitting device can be any types of voice related devices, such as a touch tone phone, a rotary phone, a cell phone, a voice conference phone, a headset phone, etc., and a receiving device can be any types of viewing devices, such as a television, a portable personal communication device, e.g. a palm pilot, or a receiving screen mounted in a vehicle, etc. The media for transmitting or broadcasting high volume information, such as streaming video, etc., can be any types of media, such as fiber or copper cables, satellites, or other broadcasting media, etc.
As an example, a system and method of accessing/browsing the Internet via a cable environment and a cable ready television are discussed below. It is appreciated that the system and method of accessing/browsing the Internet via a satellite television or any other broad band receivers can be implemented within the scope of the present invention.
In
The stack of computers access/browse the Internet 107 based on the respective command signals, and retrieve/organize the Internet contents and/or telephone interface command menu based on the Internet browser. The signals carrying the Internet contents and ID are then sent to cable subscribers to be viewed on a cable TV 108 via cable media 124. The cable TV 108 is coupled to a cable box 110, which includes a filter 131 (in
The cable box 110 also includes a frame grabber 132, which locally refreshes the Internet contents and/or telephone interface command menu until a subsequent request is made. The Internet contents and/or telephone interface command menu are presented on the cable TV to be viewed by the user.
Since the speed of making the subsequent request is much slower than the speed of cable TV transmission, the real time use of an Internet designated cable channel is significantly reduced. Accordingly, a virtual number of users can subscribe to such Internet designated cable channel without losing privacy of Internet contents that each of the user's is viewing. It will be appreciated that the Internet browser is customized and is interactive between the requester and the contents displayed.
The phone 102 is preferably coupled to a voice recognizer 114 (in
In
The command signals are then sent to the cable system 106. It is appreciated that the computer 116, which operates the voice recognizer 114, may also be implemented in the cable system 106 within the scope of the present invention.
In
In
In
Further, the cable box 110 includes the frame grabber 132. The frame grabber 132 is used to locally refresh the Internet contents and/or telephone interface menu displayed on the user television until a subsequent request is made to change the Internet contents. Since the changes from one Internet content frame to the next Internet content frame are generally small and made in slow speed, e.g. one's speaking speed, the system can be adapted to be used by a virtual number of users, as opposed to a limited number of users in a typical video-on-demand circuit system. It is also noted that the ISP may be a part of a cable operator (not shown) without departing from the present invention.
It is appreciated that the telephone interface command menu can be in a variety of forms. The interface may include commands such as edit, exit, show previous, show next, etc.
It is noted that the voice recognition system can be implemented in conjunction with a control device. It is also noted that the present invention may be operated with or without the voice recognition system. In one embodiment, the control device drives a stream of commands to a stack of computer processors, a supercomputer, or the like. The control device may be a mouse, keyboard, joystick, or simple play station type device, television remote control, or the keypad of the phone, in addition to controls that are driven through a voice recognition configuration.
It is further noted that a phone line or voice line can be implemented in conjunction with a cable line or satellite signal wave. In one embodiment, phone lines or voice lines can be configured and arranged as a part of a cable or satellite hookup to a home or other receiving destinations.
In addition, the Internet TV system of the present invention can be used in association with a security system, which is based on individual characteristics of each user's voice. Voice is as individual as a fingerprint. The voice recognizer can be arranged or configured to screen out other voices or noises received at the voice recognizer, such as ambient noise, or to only recognize/interpret/analyze a specific user's voice profile in performing a specific Internet browsing request. For example, a teen may not be able to request a certain Internet browsing requests, etc., while parents' voice profiles would be accepted for these requests.
It is further noted that in the present invention, computers, supercomputer, or stacks of computers, which are used to process a voice mode or other modes of instruction request, are provided to the users as a service. They are generally located in a remote site from a user's transmitting or control device. One advantage of this is that users do not have to purchase upgraded computers or other “information appliance” every time when there is an advance or improvement in computing technology that improves processing functionality. The processing functionality can be added to the system by upgrading the service to the users without disrupting their current service or forcing them to buy new equipment. Further, it is appreciated that processing power of these computers can be used for other types of personal computing functions. A remote personal computer type service can be offered on the present system as well as Internet access as described above. For example, a word processor or a database management program can be offered as a service on the present system, as opposed to a product that a user often has to buy. These services can be offered to a user in a similar fashion as a voice messaging service offered by telephone companies.
It is also appreciated that the services offered the Internet can be downloaded at a local site, e.g. at a set top box of the television, etc., for a user to make subsequent uses. This is similar to the movie menu services offered in hotels.
Further, instead of a frame grabber as described above, an intelligent router can be implemented within the scope of the present invention. Typically, a frame grabber can be used to refresh a static image or low speed video clips, whereas an intelligent router can be used for transmitting high speed streaming video type of data. One way of describing the difference of the two is to introduce the processes of addressing packets of information, reading and routing the packages as well as opening the package envelopes. In the case of a frame grabber, a full address of packages of information is read at an individual recipient or local site, and a static image is refreshed on a screen at that location until a new packet is opened up to replace it. In the case of an intelligent router, a partial address read at trunks or branches of a media system, e.g. a cable system, allows for package delivery in a more sophisticated way and thereby creating enough capacity to provide streaming video to an individual recipient or local site at, e.g. thirty-two new frame packages of information per second. An alternative way of providing such capacity may be to create a massive number of new channels, one for each specific household or user, which relies significantly on advancement of channel bandwidth technology.
Accordingly, the present invention provides a system in which voice and an instruction stream come from a control device in a user's location and are sent upstream to a computer or a stack of computers at a remote site. In the case of voice, a translation is made from sounds to a stream of text and processing commands. A stack of computers process requested functions upon receiving the commands, for example, accessing/browsing the Internet interface and/or performing other computing functions. The requested information is then displayed on a television type of receiving device. The present system is arranged and configured in a loop between the control device at a local site, such as home, where requests are sent to a computer at a remote site via a narrowband medium, such as a phone line, and a display at the local site for displaying requested information from the computer via a broadband medium, such as a cable or satellite channel or medium.
The foregoing description of the exemplary embodiment of the invention has been presented for the purposes of illustration and description. It is not intended to be exhaustive or to limit the invention to the precise form disclosed. Many modifications and variations are possible in light of the above teaching. It is intended that the scope of the invention be limited not with this detailed description, but rather by the claims appended hereto.
