Abstract: Distributed navigation of broadcast signals is provided through an on-line application connected through a second network connection. A customer receives the broadcast signals through a first network connection, and navigates the broadcast TV content through an on-line application by a browser connected through a second network connection. The present on-line application provides flexible and re-configurable content services, which will need to be customized once for each service provider, but will render consistently on a variety of PC and non-PC client devices. Further, the present on-line application can provide targeted advertising by maintaining an advertising profile for each viewer, determined in part by recording data about the navigating of the content of the broadcast signals, and by recording a plurality of selections of the viewer transmitted to the on-line application. The on-line capability further provides ease for roaming access.

Abstract: A method for providing audio portions of broadcast television signals is disclosed. A television signal is buffered by a multimedia client. In response to a user request, audio data may be obtained from a service provider and sent back to the multimedia client using a network back-channel. The obtained audio data may be synchronized with a video portion of the television signal and output to an audio device, while the television signal is output to a display device.

Abstract: An exemplary multi-axis television navigation system defines television navigation axes according to attributes of television programs. In one implementation, if a television program has an attribute defining an axis, then the exemplary system links a predefined database query associated with the axis to metadata for the television program. When launched, the predefined query returns a sequence of navigable television programs having the attribute that defines the axis.

Abstract: Distributed and highly software reconfigurable CMTS (CMRTS) device, based on MAC and PHY units with FPGA and DSP components, for a HFC CATV network. The various CATV RF modulators, such as QAM modulators, may be divided between QAM modulators located at the cable plant, and remote QAM modulators ideally located at the fiber nodes. A basic set of CATV QAM data waveforms may optionally be transmitted to the nodes using a first fiber, and a second set of IP/on-demand data may be transmitted to the nodes using an alternate fiber or alternate fiber frequency, and optionally using other protocols such as Ethernet protocols. The nodes will extract the data specific to each neighborhood and inject this data into unused QAM channels, thus achieving improved data transmission rates through finer granularity. A computerized “virtual shelf” control system for managing and reconfiguring the FPGA and DSP based CMTRS units is also disclosed.

Abstract: Systems and methods are provided for identifying instances of media programming available within a media distribution system. An exemplary method involves searching a listing of media programming available from a first content source using search criteria indicative of a desired media program to identify an instance of the desired media program available from the first content source, obtaining a target program identifier associated with the desired media program from that instance, identifying another instance of the desired media program in a second listing of media programming available from another content source using the target program identifier, and providing a combined search result that indicates availability of the desired media program from the content sources.

Abstract: A system and method for delivering content over a network is provided. Content may be primary content (e.g., music or a movie) or ancillary content (e.g., an advertisement). The ancillary content may further be classified as universal ancillary content that all users of the present system will receive; targeted ancillary content that particular users of the present system will receive; and context-specific ancillary content that users of the present system and viewing particular primary content will receive. The type of primary and/or ancillary content delivered to the user will depend, in part, on indicia of the user of a device receiving the content. The present invention seeks to ensure that a user has relevant and up-to-date ancillary content notwithstanding the nature or date of the primary content.

Abstract: Firmware is installed in a cable modem, enabling detection of the presence or absence of a cable trap in the feed of a customer location. Such a cable modem includes a trap-detection module and a trap-detection object. The trap-detection module is configured to determine whether a video signal is present at a cable-television frequency. The trap-detection object is configured to store data as to whether the video signal is present. For example, a first piece of data is stored if the video signal is present, indicating absence of a properly functioning cable trap between a cable head-end and the cable modem. A second piece of data is stored if the video signal is absent, indicating presence of a properly functioning cable trap between the cable head-end and the cable modem.

Abstract: In a local information broadcast system according to the present invention, a content distribution center distributes broadcast contents of local information to broadcast devices arranged in a service area via a master station. Each of the broadcast devices receives the distributed contents by a communication unit, stores the contents in a storage unit and cyclically outputs the stored contents by an output unit, converts the contents into broadcast signals in a transmission system of a digital broadcast and broadcasts the broadcast signals to the service area by a transmission unit, and provides a receiving terminal capable of receiving digital broadcast in the service area of the local information.

Abstract: A media server component serves media programs to a plurality of client media players across a distribution network taking into consideration available data transfer rate and media player characteristics. The media programs are served adaptively, considering screen size, refresh rate required, frame rate, audio format, user preferences at the recipient media player's end and estimated available data transfer rate. The media server component responds to the channel conditions, recipient media audio and video characteristics and the user preferences at the recipient device's end in real time, by either delivering a stored program or transcoding the stored program in real time.

Abstract: EPG data regarding programs and their scheduled times are structured and/or transmitted in such a way that program and schedule records are interleaved. This scheme allows better handling by receiving devices such as embedded devices (i.e. LCD remote controls), because a more efficient reception and storage of transmitted data is possible. In particular, the receiving device can read, parse and store the downloaded EPG data on the fly as it is being received (it can start reading, parsing and storing before the complete reception of data id finished). At any time when the device would have to stop storing EPG data into persistent storage, (almost) all of the data that was stored can actually be used.

Abstract: A computer-implemented method includes receiving a search request related to media programming and generating a search. The result has a list of one or more collections of episodes responsive to the search request, and a schedule grid displaying a plurality of episodes on a plurality of different channels for a time period, including at least one program responsive to the search request.

Abstract: A technique is disclosed for identifying members of an audience tuned to a program broadcast by a programming signal source, comprising the steps of storing personal identification signals in a plurality of portable devices to be carried by members of the audience; periodically transmitting said identification signals from the portable devices; providing a stationary detector to detect the identification signals if they exceed a selectable response of said detector; and setting the selectable response of said detector to a level such that the identification signals are detected only if the respective portable devices are located relative to the detector in positions where persons can perceive performance of the broadcast program.

Abstract: The user can respond to a media segment wherein the media segment may be associated with a schedulable event. Software on the device can then schedule the event into an electronic calendar system, and/or may use data associated with the media segment. At the appropriate time, the electronic calendar system may notify the user of the scheduled broadcast and/or event.

Abstract: One embodiment of the present invention sets forth a technique for adapting playback bit rate to available delivery bandwidth in a content delivery system comprising a content server and a content player. A content player periodically estimates whether a given playback bit rate can feasibly provide complete playback for a given title assuming currently available bandwidth. If playback becomes unfeasible at a current bit rate assuming currently available bandwidth, then the content player adapts the bit rate downward until a feasible bit rate is achieved. If playback is feasible using a higher bit rate, then the content player may adapt the bit rate upward.

Abstract: During tuner manufacture, the unique power parameters as a function of frequency and channel are stored on a memory unique to each tuner. When the tuner is subsequently incorporated into another device, such as a modem, the stored power parameters are made available to the subsequent device, thereby overriding the need for subsequent calibration tests to be run. The stored parameters aid in remote testing of the communication device and also allow for individual channel by channel setting of TOP levels.

Abstract: A scheme for providing programs to multiple end user devices. Two types of media streams that convey a first group of programs are provided to multiple end user devices via an edge device. The two types of programs include a unicast media stream and a multicast media stream. When a request from a first end user device to view a first program that belongs to the first group of programs is received, a type of a media stream that conveys the first program to a second end user device is selectively switched, in response to bandwidth constraints imposed on a communication path coupled to the edge device.
