摘要： The MPEG4 is expanded to permit the use of the 4:2:2 format and the 4:4:4 format. To this end, there is provided an encoder adapted for encoding a picture in terms of a macro-block made up of a block of luminance Y and a block of chrominance Cr, Cb. The encoder includes a VOP encoding unit 3 for encoding the picture as reading of a flag (cbpc) specifying the state of encoding of the chrominance block and a flag (cbpcb, cbpcr) specifying the state of encoding of the chrominance block associated with the types of the chrominance Cb, Cr is adaptively changed responsive to a flag (chroma_type) representing the chrominance format of the picture and to the flag (cbpc) specifying the state of encoding of the chrominance block.

摘要： In an image signal demultiplexing apparatus, a scene descriptor, object descriptors and respective bitstreams are separated by a demultiplexer circuit, and the respective bitstreams are decoded by decoders. Within output data from the decoders, output data associated with the same object descriptor (output data composing the same object) are mixed by a mixer circuit. Subsequently, the mixed output data is supplied to an object synthesizer circuit of a synthesizer circuit which is supplied with a corresponding node. Then, the object synthesizer circuit corresponds one image to one object to perform texture mapping. An image signal multiplexing apparatus multiplexes the scene descriptor, respective bitstreams, and information related to the bitstreams.

摘要： An encoder considers a frame representing a picture as comprised of areas. For each area, the encoder decides which of frame-based or field-based orthogonal transformation will be most efficient at reducing spatial redundancy in that area. For each area, the encoder decides which of frame-based or field-based predictive encoding will be most efficient at reducing temporal redundancy in that area. The encoder encodes each area of the picture frame using the most efficient orthogonal transformation technique and using the most efficient predictive encoding technique to produce an encoded signal. A decoder decodes the encoded signal. The encoded signal is recorded on a recording medium, transmitted over a transmission channel, or broadcast.

摘要： Mismatch errors occur in the local decoder of a MPEG-standard compressor for a motion picture signal, and in an MPEG-standard expander for a compressed motion picture signal. This is because of the lack of a standard for rounding results of *.5 (* is an integer) obtained when a set of transform coefficients resulting from compressing the motion picture signal is inversely orthogonally transformed. The invention prevents mismatch errors by pre-processing the set of transform coefficients prior to the inverse orthogonal transform. The transform coefficients in the set are summed, and the parity (odd or even) of the sum is judged. When the parity of the sum is judged to be even, the parity of one of the transform coefficients in the set is inverted to provide a parity-inverted transform coefficient. This makes the parity of the sum odd. Then, when the set of transform coefficients including the parity-inverted transform coefficient is inversely orthogonally transformed, none of the results of the orthogonal transform will have a value of *.5.

摘要： According to the present invention, when an ATV signal is recorded by a digital VCR in the conventional television signal record mode, variable speed reproduction data composed of HP data containing I frame is redundantly recorded in a surplus record area that is formed by the difference between the transmission rate of the ATV signal and the transmission rate of the conventional compressed digital video signal. When variable speed reproduction is performed, the variable speed reproduction data is reproduced.

摘要： Mismatch errors occur in the local decoder of a MPEG-standard compressor for a motion picture signal, and in an MPEG-standard expander for a compressed motion picture signal. This is because of the lack of a standard for rounding results of *0.5 (* is an integer) obtained when a set of transform coefficients resulting from compressing the motion picture signal is inversely orthogonally transformed. The invention prevents mismatch errors by pre-processing the set of transform coefficients prior to the inverse orthogonal transform. The transform coefficients in the set are summed, and the parity (odd or even) of the sum is judged. When the parity of the sum is judged to be even, the parity of one of the transform coefficients in the set is inverted to provide a parity-inverted transform coefficient. This makes the parity of the sum odd. Then, when the set of transform coefficients including the parity-inverted transform coefficient is inversely orthogonally transformed, none of the results of the orthogonal transform will have a value of *0.5.

摘要： The present invention is directed to an image information encoding apparatus, used in receiving compressed image information through network media when processing of such compressed image information is performed on storage media. A picture sorting buffer delivers information of picture type of frame Picture_type to a picture type discrimination unit. The picture type discrimination unit transmits command to a motion prediction/compensation unit on the basis of that information. The motion prediction/compensation unit generates predictive picture by using filter coefficients having the number of taps lesser than that of P picture with respect to B picture for which operation quantity and the number of memory accesses are required to more degree as compared to P picture on the basis of that command.
