    摘要: The disclosed embodiments relate to an apparatus and a method for re-synthesizing signals. The apparatus includes a receiver for receiving a plurality of digitally multiplexed signals, each digitally multiplexed signal associated with a different physical transmission channel, and for simultaneously recovering from at least two of the digital multiplexes a plurality of bit streams. The apparatus also includes a transmitter for inserting the plurality of bit streams into different digital multiplexes and for modulating the different digital multiplexes for transmission on different transmission channels. The method involves receiving a first signal having a plurality of different program streams in different frequency channels, selecting a set of program streams from the plurality of different frequency channels, combining the set of program streams to form a second signal, and transmitting the second signal.

    摘要: Mechanisms are provided for allowing a mobile device to dynamically obtain program guide data. A mobile device having the capability of playing media streams is configurable to dynamically request program guide structure information followed by program guide content information. In one example, the program guide structure information allows a user to begin navigating the program guide data in an active and dynamic manner. Program guide content information including data such as program titles, times, icons, and links are then downloaded and displayed as needed. Potentially limitless amounts of program guide data can be provided on a mobile device. Program guide content information can be provided in a generic manner while allowing user layout customization. Program guide information can also be preemptively provided to a mobile device based on a variety of criteria.

    摘要: A method for communicating data, such as audio/video (AV) data, over plural channels involves selecting data and encryption information, and encrypting the data with the encryption information to thereby produce encrypted data. The encryption information is broken into portions. The encrypted data is communicated by way of at least one of the plural channels, and at least some portions of the encryption information are communicated over at least one channel other than that one over which the encrypted data is communicated. In a more general case, the encrypted data is sent over one channel, and the encryption information is divided and sent over several other channels.

    摘要: An adaptive digital image processor precedes an MPEG2 encoder. The processor receives a high definition video signal intended for broadcast or storage, and adaptively low-pass filters the signal. The signal is subjected to low-pass two-dimensional filtering to eliminate encoding artifacts and related noise. The video signal is then horizontally down-sampled to create a lower resolution hybrid signal. A receiver decodes and decompresses the hybrid signal. The hybrid signal is upsampled to its original resolution using existing hardware and software with a software modification.
