Communication device, multicast control method, and scheduling control method
A communication device, a multicast control method, and a scheduling control method are disclosed. The communication device includes: a decoding buffer that stores a first multicast packet received from a first node and a second multicast packet received from a second node; an encoder that performs network coding of the first and second multicast packets; and a transmitter that transmits the network-coded packets output from the encoder to the first node and the second node..

Entropy coding
An encoder for encoding a sequence of symbols is described which has an assigner configured to assign a number of parameters to each symbol of the sequence of symbols based on information contained within previous symbols of the sequence of symbols; a plurality of entropy encoders each of which is configured to convert the symbols forwarded to the respective entropy encoder into a respective bitstream; and a selector configured to forward each symbol to a selected one of the plurality of entropy encoders, the selection depending on the number of parameters assigned to the respective symbol.. .

Method and system for embedding metadata in multiplexed analog videos broadcasted through digital broadcasting medium
A method and system for broadcast of additional content such as metadata required for client specific interactive application in an analog domain along with conventional audio, video and psi or si data is disclosed. The present invention enables transmission of encoded audio data or epg data, timestamp information required for audio video synchronization referred to as metadata by embedding such metadata in the pixels of video pixels and then encoding by the standard video encoder to generate an encoded stream.

Device for encoding and decoding using smaller block of symbols
A method of encoding user data into codevectors of an error correcting code, includes generating a first block of data symbols including user data symbols and dummy data symbols; encoding the first block using an ecc encoder to obtain a codeword comprising the first block of data symbols and a second block of parity symbols; and generating a codevector by selecting a user data portion of the user data symbols from the first block and a parity portion of the parity symbols from the second block. The sum of a number of the user data portion and a number of the parity portion is smaller than the sum of a number of the user data symbols and a number of the parity symbols of the second block..

Rate adaptive irregular qc-ldpc codes from pairwise balanced designs for ultra-high-speed optical transports
Systems and methods for data transport include encoding one or more streams of input data using one or more quasi-cyclic low density parity check (qc-ldpc) encoders; controlling irregularity of the qc-ldpc encoded data while preserving the quasi-cyclic nature of the ldpc encoded data and eliminating the error floor phenomenon. A parity-check matrix may be partially reconfigured to adapt one or more code rates; and one or more signals are generated using a mapper, wherein the output of the mapper is modulated onto a transmission medium.
