摘要:
A contents transmission system comprising a first terminal which receives a first code stream produced by compression-encoding contents and has a converter section converting the first code stream into a second code stream having a data size smaller than that of the first code stream, a transmission section transmitting the second code stream, and a second terminal which receives the second code stream transmitted from the first terminal and has a reconstruction section reconstructing the contents by decoding the second code stream.

摘要:
In a coding system where in an error correction/detection coding is combined with a synchronization recovering technique using a synchronization code, the problems of a pseudo synchronization and a step out due to error detection are solved. There is provided a coding part 212 for coding an input multiplexed code string 201 to an error correcting-/detecting code comprising an information bit and a check bit, and code string assembling part 213 for inserting a synchronization code into any one of a plurality of periodically predetermined synchronization code inserting positions in the code string 201, for arranging the information bit at an optional position in the code string, and for arranging the check bit at a position other than the synchronization code inserting positions in the code string 201 to assemble an output code string 205.
