摘要： A system includes a signal-processing engine configured to generate a video data stream including a plurality of data packets based on a received video signal. A first subset of the plurality of data packets is usable to generate a video display of content having a first quality and all of the plurality of data packets are usable to generate a second video display of the content having a second quality. The second quality is higher than the first quality. The signal-processing engine is further configured to distinguish the first subset of the plurality of data packets from other data packets of the plurality of data packets by applying a tag to particular data packets to form tagged data packets. The system also includes a transmitter coupled to the signal-processing engine and configured to transmit the plurality of data packets of the video data stream.

摘要： A satellite transponder switch (STS) maintains a table that maps set-top boxes (STBs) to carrier frequencies. The STS receives a first request from a first STB for a first transponder band and a second request from a second STB for a second transponder band. The STS receives contact from the first STB on a control channel upon power-up of the first STB and in response to the contact from the first STB, assigns a first carrier frequency to the first STB. The STS frequency shifts the first transponder band to a first carrier frequency assigned to the first STB and the second transponder band to a second carrier frequency assigned to the second STB. The STS outputs a signal that comprises the frequency-shifted first and second transponder bands to the first STB and the second STB. The frequency-shifted first and second transponder bands are separated by a separation band. A first carrier frequency of the signal is unique to the first STB and a second carrier frequency of the signal is unique to the second STB.

摘要： A system and method are disclosed for providing a unified video data stream for diverse receiving platforms. In some embodiments, the unified data stream can provide video data to multiple receiving devices with diverse video data input requirements. The communication system can include a digitizer that converts an analog video to a high resolution (HR) digital video signal. The communication system can also include a signal processing engine that receives the HR digital video signal, compress the video signal, creates video packets from the compressed signal, and identifies at least a portion of the video packets for distribution to lower resolution devices. The HR data stream can be sent to high resolution devices wherein the identified packets can be “copied” from the HR data stream and sent to devices having lower resolution requirements.

摘要： A satellite transponder switch (STS) maintains a table that maps set-top boxes (STBs) to carrier frequencies. The STS receives a first request from a first STB for a first transponder band and a second request from a second STB for a second transponder band. The STS accesses a first satellite feed and polarity based on the first request, and a second satellite feed and polarity based on the second request. The STS band-pass filters the first and second transponder bands from the first and second satellite feed and polarity, respectively. The STS frequency shifts the first transponder band to a first carrier frequency assigned to the first STB and the second transponder band to a second carrier frequency assigned to the second STB. The STS outputs a signal that comprises the frequency-shifted first and second transponder bands to the first STB and the second STB.
