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： 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： Recording unit is operative so that, in the case of carrying out high speed reproduction, switch is switched by high speed reproduction control signal inputted from the external, and a signal read out from the recording unit is inputted to VLD and formatter. High speed reproduction control signal is inputted to recording unit, switch and counter. Recording unit reproduces and outputs predetermined data in accordance with high speed reproduction control signal. At VLD, variable length encoding of MPEG is released, and syntax analysis is carried out. Counter counts the number of frames to be transmitted. Moreover, counter outputs temporal.sub.-- reference in accordance with reproduction speed indicated by high speed reproduction control signal. Header converter rewrites temporal.sub.-- reference in picture header in accordance with temporal.sub.-- reference outputted from counter. From facts as described above, high speed reproduction of moving picture can be made.

摘要： A compression-coded high definition television signal is decoded and converted to a standard NTSC signal without loss of interlacing so that the resulting picture exhibits smooth motion. The compression-coding of the HDTV signal includes DCT processing to produce an 8.times.8 block of coefficient data. Upon decoding, the upper left quadrant of the coefficient data array is used to form a 4.times.4 subblock of coefficient data but the last row of elements of the subblock is replaced by corresponding elements of the eighth row of the 8.times.8 block of coefficient data.
