摘要： An information delivery system and information delivery method can provide information delivery services that utilize network resources efficiently. A push server 3 transmits data associated with summary content 15 (summary of detailed content 23) to a push delivery controller 2, and a terminal 1 transmits data associated with the terminal 1 to the push delivery controller 2. According to these data, the push delivery controller 2 decides the terminal to which the summary content is to be transmitted, and notifies the push server 3 of the terminal. The push server 3 transmits the summary content to the terminal notified. When the terminal 1 wishes to acquire the detailed content corresponding to the received summary content, it sends to the pull server 4 a request to transmit the detailed content. In response to the request, the pull server 4 transmits the detailed content to the terminal 1.

摘要： A motion of an image in a block is detected with respect to image data D1, a coding mode to be applied thereto is selected among a plurality of prepared coding modes, and motion compensation is performed for the image data (Step S101). Then, an orthogonal transform coefficient D6 and coding mode information D3 undergo variable-length coding to generate coded data D7 (Step S103). Subsequently, in the variable-length coding of the coding mode information, a probability table for use in arithmetic coding is switched for each of binarization codes included in a binarization pattern of the coding mode information with reference to a coding mode selected in a block adjacent to the block. Thus, the image coding method, image decoding method, image coding apparatus, image decoding apparatus, program, computer data signal, and image transmission system, which are capable of enhancing efficiency of data compression for coding mode information multiplexed on coded data, are realized.

摘要： An orthogonal transform such as a DCT is carried out for image data D5 of an image in blocks obtained by dividing a frame image, the image data D5 being represented by spatial coordinates (Step S102), and a plurality of orthogonal transform coefficients D6 as image data represented by spatial frequencies are generated. Then, the orthogonal transform coefficients D6 undergo arithmetic coding, and thus coded data D7 is generated (S103). Subsequently, in the arithmetic coding of the orthogonal transform coefficients, data characteristics of the orthogonal transform coefficients to be coded, which depend on the spatial frequencies, are considered, and a probability table is switched for a predetermined orthogonal transform coefficient, and thus the arithmetic coding is carried out. Thus, the image coding method, image decoding method, image coding apparatus, image decoding apparatus, program, computer data signal, and image transmission system, which are capable of enhancing efficiency of data compression in coded data by reflecting characteristics of image data to be coded on coding conditions, are realized.

摘要： When generating a prediction image of a color difference signal, an intra prediction unit 4 carries out an intra prediction process on a target block to be encoded of a color difference signal by using the same intra prediction parameter as that which the intra prediction unit 4 uses when carrying out an intra prediction process on a target block to be encoded of a luminance signal, or carries out the intra prediction process on the target block to be encoded of the color difference signal by applying an average prediction to the target block to be encoded. A variable length encoding unit 13 variable-length-encodes a flag showing whether the intra prediction unit 4 uses the same intra prediction parameter as that used for the luminance signal.
