    摘要: An approach is provided for distributing multi-media information from a satellite broadcast system. A hub receives a signal from the satellite broadcast system, wherein the signal represents video information and audio information associated with multiple broadcast channels. The hub centrally demodulates and decodes the received signal for distribution to one of a number of access point devices. According to one embodiment of the present invention, the decoded signal represents uncompressed video and audio information corresponding to one of the broadcast channels. The access point devices convert the received decoded signal for output respective displays (e.g., television sets). The hub can also be equipped with an interface to provide access to a public data network, such as the global Internet. Further, the hub can be supplied with a digital video recording capability.

    摘要: An apparatus and method for processing content signals received from a plurality of different, and possibly dissimilar, signal sources, such as different satellite networks, and providing a display based on the content of those signals. The apparatus includes a tuner/demodulator for receiving content signals and demodulating the received content signals as programming bitstreams, and one or more access control devices for descrambling any conditional access present in the demodulated programming bitstreams. The apparatus further includes a processor, such as a system chip, which is responsible for all command and control functions. The system chip evaluates conditional access to determine whether the bitstream needs decryption, descrambling, or both, and processes a bitstream from one of the multiple signal sources for display on a suitable output device.

    摘要: A method and apparatus for synchronizing downstream circuit boards with the clock values transmitted in the incoming bitstream of a digital broadcast data signal from a digital satellite system (DSS) or digital video broadcast (DVB) is disclosed. The disclosed embodiments use the generation of quasi-periodic interrupts which latch, at the same time for all downstream circuits, local clock times. The differences between successive local clock times are compared in downstream processors to differences between a front-end circuits locked system times to determine local clock adjustment values to synchronize downstream circuits.

    摘要: A method and apparatus for enabling background caching of encrypted programming data on a storage medium for later playback in a digital video recorder (DVR) system. A set-top box (STB) equipped with a DVR searches a program guide for upcoming pay-per-view (PPV) events. When the PPV event begins, the STB tunes an appropriate transponder and begins receiving programming data packets containing audio, video, system time and conditional access data packets associated with the event, which are stored for playback on a storage medium. When the user turns the STB on and selects an option to playback a previously-recorded PPV event, the appropriate programming data is retrieved from the storage medium, and the STB recreates the original transmission timing of the data, to be displayed on a display device of the user.

    摘要: A CDMA network includes a retransmission scheduler which selectively delays the retransmission of an initially erroneously sent signal. The selected delays have an average value in a range of values which results in a single equilibrium point between input messages and output messages to avoid a bistable condition that can lower overall system throughput.

    摘要: A checkerboard subsampled image is packed in a format to remove shifts that would otherwise result in jagged edges where edges that were not jagged used to exist when checkerboard subsampling is used to reduce video bandwidth. The packing format places alternate rows of a checkerboard subsampled image row by row or places alternate columns of a checkerboard image line by line. By removing the shift and jagged edges, high frequency components that are difficult compress and display as annoying artifacts are eliminated.

    摘要: A method and system for controlling a local content aggregated system includes a switch module receiving external channel signals, user receiving devices and a local headend generating a local channel signal. The local headend communicates the local channel signal to the switch module and communicates local channel program guide data to the user receiving devices. The user receiving devices receive external program guide data corresponding to the external channels. The user receiving device selects either a first external channel signal from the external channel signals or the local channel signal at the program guide to form a selection signal corresponding to a selected channel at a first user receiving device of the user receiving devices. The user receiving device communicates the selection signal to the switch module, which is switched in response thereto. The switch module communicates the selected channel signal to the first user receiving device.
