Contents transmission system and contents processing apparatus

A contents transmission system comprising:

• a first terminal having a converter section which converts a first code stream produced by compression-encoding contents into a second code stream having a smaller data size than that of the first code stream;
• and
• a second terminal reconstructing the contents by decoding the second code stream, receiving the first code stream and transferring the received first code stream to said first terminal,
• said converter section converting the first code stream transferred from said second terminal into the second code stream and transferring the converted second code stream to said second terminal.

A contents transmission system comprising:

• a plurality of terminals including at least one terminal which receives a code stream produced by compression-encoding contents and decodes the code stream to reconstruct the contents;
• a transmission channel connecting said plurality of terminals to each other;
• and
• a contents processor device which gathers to at least one of said terminals the code streams received by said plurality of terminals via said transmission channel, decodes the code streams, and then combines the code streams to reconstruct the original contents.

A contents transmission system which comprises:

• a plurality of terminals;
• a first transmission channel which connects said plurality of terminals to each other;
• and
• a second transmission channel;
• and
• wherein said plurality of terminals includes a transmission section configured to transmit a code stream produced by compression-encoding contents via said second transmission channel, at least one of said terminals has a function of separating a code stream into a plurality of separated code streams, transmitting one of the separated code streams via said second transmission channel and transmitting the other separated code streams to the other terminals via said first transmission channel, and
• the contents are reconstructed from the separated code streams transmitted from said plurality of terminals via said second transmission channel.

A contents transmission system comprising:

• a plurality of terminals which each have functions of producing a code stream by encoding contents and reconstructing the contents by decoding the code stream, at least one of said terminals working as a server;
• a first network connecting said plurality of terminals to each other;
• a second network;
• and
• a transmission channel connecting said server to said second network, said server taking a code stream from said second network through said transmission channel and distributing the code stream to the other terminals in said plurality of terminals.

A contents transmission system which comprises:

• a plurality of terminals which each have functions of producing a code stream by encoding contents and reconstructing the contents by decoding the code stream, at least one of said terminals working as a server;
• a first network connecting said plurality of terminals to each other;
• a second network;
• and
• a transmission channel connecting said server to said second network;
• and
• wherein said server combines code streams produced by the other terminals in said plurality of terminals and transmits the combined code stream to said second network through said transmission channel.

A contents processing apparatus comprising:

• a receiver section which receives a first code stream obtained by encoding contents;
• a converter section which converts the received first code stream into a second code stream having a data size smaller than that of the first code stream;
• and
• a transmitter section which transmits the second code stream.

A contents transmission system comprising:

• a first terminal having a converter section which converts a first code stream produced by compression-encoding contents into a second code stream having a data size smaller than that of the first code stream;
• and
• a second terminal reconstructing the contents by decoding the second code stream, receiving the first code stream and transferring the received first code stream to said first terminal,
• said converter section converting the first code stream transferred from said second terminal into the second code stream and transferring the converted second code stream to said second terminal.

A contents transmission system for transmitting a code stream obtained by compression-encoding contents, comprising:

• a first transmission channel;
• a second transmission channel;
• a first terminal which receives a first code stream through said first transmission channel;
• a second terminal which receives a second code stream through said first transmission channel;
• an exchanger device which exchanges the first and second code streams received by said first and second terminals through said second transmission channel;
• a reconstruction device which decodes the code stream received through said first transmission channel and the code stream received through said second transmission channel and combines the decoded streams to reconstruct the contents.
