    摘要: A video image decoding device (1) is equipped with a TT information decoder (14) that, in the case where encoded data includes merge/skip information that merges or skips presence information indicating whether or not frequency-domain transform coefficients are included in the quantized transform coefficients, does not decode the presence information, and a TT information inference unit (33) that, in the case where the encoded data includes merge/skip information that merges or skips the presence information, infers the presence information. The TT information decoder (14) uses presence information inferred by the TT information inference unit (33) to decode the encoded and quantized transform coefficients.

    摘要: The present invention is related to a hash-based distributed video coding architecture. At the encoder, the input video sequence is organized in Groups of Pictures (GOPs) and is decomposed into key frames, i.e., the first frame in each GOP, and WZ frames. The key frames are encoded using H264/AVC Intra frame coding. The Wyner-Ziv (WZ) frames are encoded in two parts, a hash layer and a WZ layer. To construct the hash information, the WZ frames are quantized and each quantized frame is then decorrelated using spatio-temporal prediction and entropy coded, and then multiplexed with the encoded key frames. At the decoder, the intra bit stream is H264/AVC decoded and the intra frames are stored in a reference frame buffer. The hash is decoded by inverting the tasks applied at the encoder, i.e. entropy decoding and inverse spatio-temporal prediction, and the obtained bit planes are stored. Next, Overlapped Block Motion Estimation and Probalistic Compensation (OBMEPC) is used to estimate the missing bit planes in the side - information. The decoder utilizes the hash information and the side information frame created by OBMEPC to perform online estimation of the correlation channel, and produces soft estimates used to decode the WZ bit planes.
