摘要： A single chip set-top box system and method is provided. The system comprises, for example, a transceiver, an audio/video decoder, a CPU, peripherals, DAVIC MAC and a graphics processor. The transceiver receives a digitally modulated compressed audio/video signal, and the audio/video decoder receives the compressed audio/video signal from the transceiver and decompresses the compressed audio/video signal. The graphics processor blends the decompressed audio/video signal with graphics to generate a blended video image with audio.

摘要： Signals transmitted on the backhaul links of a cloud radio access network may be compressed using joint compression encoding. Joint compression encoding may be performed using a successive estimation-compression architecture. Joint compression encoding may include designing preceding matrices that may be used with signal compression. Joint compression encoding may be applied to signals transmitted on the downlink of the cloud radio access network. One or more baseband signals to be delivered over the backhaul links may be jointly compressed using multivariate compression. Multivariate compression may be implemented using successive compression based on a sequence of minimum mean squared error (MMSE) estimations and per BS compression.

摘要： In a data transmission system such as a television service provider system, compensation value data corresponding to information lost during lossy compression of program content (which may or may not already be compressed prior to the lossy compression) may be sent to a customer along with the lossy-compressed content. At the customer end, the compensation value data may be used during decompression to provide higher quality content to the customer than would otherwise be experienced without access to the compensation values.

摘要： Disclosed are a method and an apparatus for transmitting a sparse signal, and a method and an apparatus for recovering the sparse signal. The method for recovering a sparse signal by using a sparse signal recovering device that recovers a target signal from a received signal includes receiving a measurement signal with a noise signal from a sparse signal transmitting device which scans a target signal based on a measurement matrix, performing a mutual update procedure in which a likelihood probability is calculated by using a posterior probability of the target signal based on a relation between the target signal and the measurement signal, and the posterior probability is updated by using the likelihood probability, and recovering the target signal by performing maximum a posterior estimation for a final posterior probability output through the mutual update procedure.

摘要： Transmitters and receivers deal with streams of data, wherein the receiver is expected to begin using received data before receiving all of the data. Concurrent streams are sent and FEC coding is used with the streams and done as an aggregate. The transmitter performs FEC operations over the plurality of streams, wherein source blocks from at least two streams logically associated into a jumbo source block and FEC processing is performed to generate one or more jumbo repair block from the jumbo source block. Each of the source blocks comprises one or more source symbols from their respective stream. The jumbo source symbols can be of constant size and are suitably aligned along size boundaries that make processing efficient. Each source symbol need not be the same size, and the number of source symbols from each stream in a jumbo source block need not be the same value across streams.
