Abstract:
A recording medium comprising a first portion in which an encoded picture signal is recorded and a second portion in which header information is recorded for access by a reproducing apparatus having a decoder for decoding said encoded picture signal based on said header information, said encoded pisture signal having a plurality of macroblocks and representing frame-based type orthogonal transformation coefficients and/or field-based type orthogonal transformation coefficients, said header information including macroblock address information indicating the respective location of each macroblock and information identifying the type of orthogonal transformation coefficients represented by said encoded picture signal, in which a respective type of the orthogonal transformation coefficients represented by said encoded picture signal is the one of the frame-based type of orthogonal transformation coefficients and field-based type of orthogonal transformation coefficients which has the least amount of data so as to reduce the amount of data recorded on said recording medium.
