2. Description of the Prior Art
As the technology related to portable electronic device advances and the need for portability increases in relation to the current market trend, traditional personal computers are transforming to lighter and more dedicated devices provided for or targeted at different purposes and user groups including such as gaming, telecommunication, web browsing and media streaming. Such shift of market and technology trends related to advanced needs of portability and interactions demanded by users of such electronic devices are in fact facilitating not only the improvement of traditional personal computers, laptops or smart-phones to be more powerful and/or integrated with more features and functions than ever but also a new category or breed of portable electronic devices with more dedicated functions for certain purposes and greater portability at the same time.
In view of the merits of greater portability as well as interaction provided by such newly evolved breed of electronic devices previously mentioned, the inventor realizes that electronic designers and manufacturers are introducing a “lighter” version of portable personal computers or laptop to the market while telecommunication device designers and manufacturers are, in general, offering a “heavier” version of mobile phones such as smart-phones such that the new growing market and user demand of high portability as well as interactive functions may be fulfilled. Some known examples of such new breed of devices may include: iPad by Apple®, Playbook by RIM®, Cius by CISCO®, Galaxy Tab by Samsung®, Libretto by Toshiba®; and examples of known smart phones may be: iPhone by Apple®, Blackberry Bold by RIM®, Galaxy S by Samsung®, HD7 by HTC™. In general, these portable devices share some common building blocks of traditional personal computers but with greater portability in terms of their size, weight as well as with greater interactive and integrated functions with more dedicated applications and telecommunication capabilities including via such as known 3G, 4G or Wi-Fi™.
As such new breed of portable electronic devices are being introduced to the market, the inventor also realizes that each one of such devices may be operated under a specific platform or OS that may be unique from each other, which may be good in providing varieties to the market in general but may too raise a preference issue to the user depending on his/her own demands in terms of such as function, design or performance of different operating systems and devices. Instead of choosing one particular type of portable electronic device miming a certain type of operating systems including such as Windows® by Microsoft®, iOS® by Apple®, Android® or Linux® by Google®, Blackberry® OS by RIM®, the inventor realizes an user may advantageously be provided with an universal apparatus capable of communicating with the any example of new breed of electronic devices running any certain type of operating systems and may be advantageously free from the preference selection issue while still being able to utilize or interact with the any one such new breed of electronic devices running different type of operating systems.
However, there are at least two major concerns to be considered in providing an electronic apparatus capable of advantageously communicating and interacting with the newly introduced breed of portable electronic devices, one is related to the various different platforms or operating systems being adapted by different electronic devices and the other is to preserve the merits of great portability and being light in terms of operation and hardware structures or components of portable electronic devices demanded by the market trend. Therefore, there is a need to provide an electronic apparatus capable of communicating with external device(s) of various types of operating systems while preserving a relatively “light” hardware structures to provide a highly portable and interactive devices to users.
Furthermore, as previously mentioned that portable devices are integrated with more functions to be easily accessed by and interacted with users for more dedicated purposes or services including such as gaming, web browsing, teleconferencing and navigation. The inventor realizes that in order to provide an electronic apparatus capable of communicating with external devices of various of different operating systems offering more dedicated services or applications, the most accessible functions or main services of the communicated external devices shall be preferably preserved, controlled and/or interacted by users while preserving a relatively less hardware structures to provide a highly portable and interactive devices to users.
In view of the foregoing, it is desirable to provide an electronic apparatus capable of communicating with external device(s) of various of different types of operating systems such that applications and services of the connected/communicated external device of different types of operating systems in relation to such as interactive gaming, teleconferencing, web browsing, media playing, navigation, image displaying or taking may all be preserved or advantageously made available, and preferably with enhanced data transmission, while realizing or having a relatively “light” hardware structures with great portability and interactive feasibility to users.

As shown in
The RX side 10 (refer back to
-
- the mapping absolute position (x′, y′) on the phone-like screen=the current position (x, y)×mapping_ratio,
where - mapping_ratio along x-axis=x-axis_resolution of phone-like screen/x-axis_resolution of pad-like screen;
- mapping_ratio along y-axis=y-axis_resolution of phone-like screen/y-axis_resolution of pad-like screen;
- given the same origin for both screens 1202 and 1002.
- the mapping absolute position (x′, y′) on the phone-like screen=the current position (x, y)×mapping_ratio,
Alternatively, the mapping movement (delta_x′, delta_y′) on the phone-like screen can be obtained as following expression:
-
- mapping movement (delta_x′, delta_y′) on the phone-like screen=current movement (delta_x, delta_v) on the pad-like screen×mapping ratio,
where - delta_x=x1−x0; delta_y=y1−y0;
- mapping_ratio along x-axis=x-axis_resolution of phone-like screen/x-axis resolution of pad-like screen;
- mapping_ratio along y-axis=y-axis_resolution of phone-like screen/y-axis resolution of pad-like screen;
given the same origin for both screens 1202 and 1002, - where xo and y0 represents the old position on the pad-like screen, and x1 and y1 represents the new position on the pad-like screen while each of the mapping ratios has a value less than one when the display size of the pad-like screen is larger than that of the phone-like screen. Thus, the operating system 1204 can be further provided for performing the actual operation at the second screen based on the second position information, such that the screen 1002 can display results from the actual operation. As a result, the RX side 10 can control multimedia contents played at TX side 12 in realtime fashion due to up-scale and down-scale operations by the coordinate mapping unit 1004 (RX side) and the coordinate calculating unit 1208 (TX side).
- mapping movement (delta_x′, delta_y′) on the phone-like screen=current movement (delta_x, delta_v) on the pad-like screen×mapping ratio,
Noticeably, the first position information may further include the current position of the cursor on the pad-like screen 1002 of the RX side 10, and the resolution data of the RX side 10, e.g. 1920×1080, and the second position information can be calculated so as to obtain the mapping position of the cursor on the phone-like screen 1202, e.g. scaling down to a resolution 480×320. For example, the actual action can be “play a video movie” when the mapping position of the cursor on the screen 1202 is pointed on a “play” icon. As a result, the user can “touch” on the pad-like screen 1002 of the RX side 10 to implement operations without access to the phone-like screen 1202 as if what he/she usually does on the phone-like screen 1202 of the TX side 12. On the other hand, all the tasks requiring extensive computing power/resources are handled by the TX side 12, and only the display task is duplicated (mirrored) to the RX side 10 from the TX side 12 such that the multimedia contents can be presented in realtime fashion between the pad-like screen 1002 of the RX side and the phone-like screen 1202 of the TX side 12.
For example, please refer to

Besides, the present invention discloses another method for controlling in realtime fashion multimedia contents between a RX side having a first touch panel and a TX side having a second touch panel via a network communication. The multimedia contents comprise at least a screen frame data (not shown) where the screen frame data includes the screen resolution data, image data displayed on the screen and audio data. The method comprising the steps of:
-
- Step 1: detecting at least one touch signal from the second touch panel 1202, for example, the user may touch the touch-sensitive phone-like screen 1202 to do something, and the “touch” can be detected and a touch signal will be sent to OS for particular operation;
- Step 2: in response to detecting the touch signal from the second touch panel, compressing the screen frame data on the TX side and transmitting to the RX side so that the RX side decompresses the compressed screen frame data so as to obtain a TX's resolution data, where the TX's resolution data is provided together with a RX's resolution data to scale the screen frame data so as to display the screen frame data to fit with the RX's touch panel;
- Step 3: detecting at least one touch signal from the first touch panel;
- Step 4: in response to detecting the touch signal from the first touch panel, the further steps including:
- Step 4-1: converting the touch signal on the RX side into touch data associated with a first position information defining a virtual operation on the first screen corresponding to an actual operation on the second screen, the first position information being with respect to a first coordinate system of the first screen;
- Step 4-2: transmitting the touch data from the RX side to the TX side via the network communication, and calculating on the TX side a second position information with respect to a second coordinate system of the second screen based on the first position information, and
- Step 4-3: performing the actual operation at the second screen based on the second position information; and
- Step 5: implementing an override mechanism to assign the TX side a higher priority overriding the RX side when the two detecting events (respectively from the TX and RX sides) occur simultaneously, for example, the phone-like screen 1202 will override the pad-like screen 1002 to take control when the user receives an incoming call from the phone-like screen 1202, and the override mechanism is implemented by a software program installed at the TX side. That means the TX side can dominant the RX side to facilitate the communication since the user has paid attention on doing the task at the TX side rather the RX side (e.g. pick-up the incoming call).

For example, please refer to

Noticeably the spirit of the present invention is to utilize a RX side to control multimedia contents played at transmitting entities of different types of operating systems in realtime fashion, wherein the RX side only transmits touch data and sensor data for a TX side to perform actual operation, and displays the multimedia contents of the TX side. Those skilled in the art should make modifications or alterations accordingly. For example, the RX side 10 can be foldable, portable, or any other types to meet each user's need(s).
Besides, the network communication NC may preferably include a Wi-Fi communication and a Bluetooth (BT) communication, and since the touch data and sensor data have less data volume while the multimedia contents have greater data volume, the touch data and the motion date are preferably transmitted to the TX side 12 via the BT communication, while the multimedia contents are preferably transmitted to the RX side 10 via the Wi-Fi communication. It can be understood that the transceiver 1006 and 1206 of the present invention may be a wireless module adapting other communication standards or profiles including such as IEEE 802.16 (WiMAX), CDMA2000, WCDMA, TD-SCDMA, LTE, TDLTE, Bluetooth-profile and combination thereof or a wired module.
Furthermore, the video data of the multimedia contents decompressed and outputted by the decompressing unit 1010 may preferably from a MJPEG format to a RGB format and transmitted or outputted to the screen 1002 in a LVDS format via a display interface converter such as a RGB-to-LVDS converter. It can be understood that other video stream formats such as ITDMI and related interfaces may also be possible. On the other hand, the audio data of the multimedia contents processed and outputted may preferably be transmitted via an audio interface such as an I2S interface or standard and further to the speaker 1008.
Moreover, it is preferable that the multimedia contents transmitted and processed in video streaming may be made “real-time” or without significant delays with respect to time for the sake of low latency. In other words, in a preferred explanatory example of the present invention recited herein, the multimedia contents may be communicated between the RX side 10 and the TX side 12 and processed to output “real-time” video and audio streams to the screen 1002 and/or the speaker 1008 of the RX side 10 of the present invention. Preferably, the multimedia contents may be processed in video streaming (i.e. encoding and decoding) and communicated there between as data packets and the duration or delay of time involved in a “real-time” processing and transmission may be less than 100 ms for the sake of low latency; in one example, it may preferably be less than 10 ms, and in another example, it may approximately be 20 ms.

The event of a charging connection can be detected either by a charging detector 1226 on the TX side 12 or by a charging controller 1018 on the RX side 10. The charging controller 1018 can be implemented by a power management chip. The charging detector 1226 can receive the remaining battery capacity of the battery cells 1228 on the TX side 12; so as to send the battery capacity information to the user interface by means of the charging application 1224 managed by OS 1204, and thus users can view the icon that indicates the actual measurement of the TX's battery capacity. The charging controller 1218 on the RX side 10 can receive the actual measurement of the RX's battery capacity, and sends the measurement to the charging detector 1226 on the TX side 12, so as to facilitate the charging detector 1226 to determine what condition can be meet to implement the appropriate charging operation.
For example, when each of the remaining battery amounts is below the predetermined battery capacity percentage (i.e. Rt<Tt and Rr<Tr), a power adaptor is used to charge both the RX side 10 and the TX side 12; when the remaining battery amount of the RX side 10 is higher than its predetermined battery capacity percentage, and simultaneously the remaining battery amount of the RX side 10 is higher than that of the TX side 12 (i.e. Rr>Tr and Rr>Rt), the RX side 10 is used to charge the TX side 12; when the remaining battery amount of the TX side 12 is higher than its predetermined battery capacity percentage, and simultaneously the remaining battery amount of the TX side 12 is higher than that of the RX side 10 (i.e. Rt>Tt and Rt>Rr), the TX side 12 is used to charge the RX side 10. It is noted that the RX side may be compulsorily switched to the power saving mode by the override mechanism when the user receives an incoming call from the TX side, that is, the user currently uses the TX side rather the RX side to either answer or dial the call. Therefore, it makes sense for the user to temporarily keep the RX side idle while he or she is busy for phone call.
In the prior art, a universal apparatus capable of communicating with the any example of new breed of electronic devices running any certain type of operating systems is lack. In comparison, the present invention utilizes a RX side to control multimedia contents played at transmitting entities of different types of operating systems in realtime fashion, wherein the RX side only transmits touch data and sensor data for a TX side to perform actual operation, and displays the multimedia contents of the TX side.
