Image signal reproducing method and image signal reproducing apparatus

摘要

It is an object of the present invention to provide a transmission and receiving method for bit streams including picture data generated by carrying out encoding with which cost for bit stream decoding and/or bit stream encoding can be reduced. With the present invention bit streams from recording media on which bit streams are recorded or radio wave are reproduced using reproducing equipment having only a bit stream reproducing function and the reproduced bit stream are transmitted via a high speed digital network (93; 103). The bit stream transmitted through the high speed digital network (93; 103) is decoded or recorded using a decoder (95) having only a function of decoding the bit stream connected via the high speed digital network (93; 103).
