Encoding apparatus and encoding method, and decoding apparatus and decoding method

An encoding method comprising the steps of:

• receiving syntax information defined by an encoding standard;
• performing a first encoding of encoding the received syntax information to generate encoded information;
• transferring transmission encoded information based on the encoded information generated by the first encoding;
• performing a second encoding of encoding reproduced encoded information reproduced from the transferred transmission encoded data;
• converting the encoded information encoded by the first encoding into redefined encoded information, to generate the transmission encoded information in accordance with a transfer capacity of the transferring and a processing speed of each of the first encoding and the second encoding so as not to cause delay in the first encoding or the second encoding;
• and
• inversely converting the converted redefined encoded information to generate the reproduced encoded information.

A decoding apparatus comprising:

• a receiving section receiving a bit stream encoded in accordance with an encoding standard;
• a first decoding section decoding the bit stream received by the receiving section to generate decoded information;
• a transferring section transferring transmission decoded information based on the decoded information generated by the first decoding section;
• a second decoding section decoding reproduced decoded information reproduced from the transmission decoded information transferred by the transferring section;
• a conversion section converting the decoded information decoded by the first decoding section into redefined decoded information, to generate the transmission decoded information in accordance with a transfer capacity of the transferring section and a processing speed of decoding in each of the first decoding section and the second decoding section so as not to cause delay in decoding in the first decoding section or the second decoding section;
• and
• an inverse conversion section inversely converting the redefined decoded information converted by the conversion section to generate the reproduced decoded information.

A decoding method comprising the steps of:

• receiving a bit stream encoded in accordance with an encoding standard;
• performing a first decoding of decoding the received bit stream to generate decoded information;
• transferring transmission decoded information based on the decoded information generated by the first decoding;
• performing a second decoding of decoding reproduced decoded information reproduced from the transferred transmission decoded information;
• converting the decoded information decoded by the first decoding into redefined decoded information, to generate the transmission decoded information in accordance with a transfer capacity of the transferring and a processing speed of each of the first decoding and the second decoding so as not to cause delay in the first decoding or the second decoding;
• and
• inversely converting the converted redefined decoded information to generate the reproduced decoded information.
