摘要：Techniques for generating synchronized dictionaries for sparse coding tofacilitate coding of video content are presented. During a communication session, anencoder associated with a first terminal generates a dictionary that is synchronized with a

corresponding dictionary maintained by a decoder associated with a second terminal. Thedecoder uses the dictionary to facilitate decoding video content, based on sparse coding,received from the encoder. During a subsequent communication session between thefirst terminal and a third terminal, the dictionary is made available to a decoderassociated with the third terminal. The encoder associated with the first terminal anddecoder associated with the third terminal signal each other to identify the dictionary asbeing common between the encoder and decoder, and this common dictionary is usedfor coding content communicated between the encoder and decoder. The encoder anddecoder can update the dictionary based on the subsequent video session.
