The obtained encoded data is temporarily accumulated in an encode data buffer (110).

When the data is encoded, the parameter values are appended to the encoded data.

A communication system including a transmitter (1'), a receiver (2'), and a serial link, in which encoded data (e.g., encoded video data and encoded auxiliary data) are transmitted from the transmitter (1') to the receiver (2').

Encrypted data obtained by encryption data to be processed includes header data (501), basic condition data (502), encrypted condition data (503), and encrypted cut data (504).

The coded data is stored in the ADPCM-coded data storage region (150b).

The printer includes a coded data generator configured to generate the coded data based at least partially on the identity data.

Pattern matching can be performed on uncoded data or Oh arithmetic coded data.

The data output means outputs encoded data obtained by hierarchical encoding as the encoded data.

Data (D), which has been coded by a coder (COD) so as to obtain coded data (CD), is modified.

The interface also includes coded data.

Then the encrypted data is stored.

A video decoder or other tool receives the encoded data and MCTS control data, and processes the encoded data.

The parser receives and parses the encoded data into a plurality of parsed data streams, with each of the parsed data streams including a portion of said encoded data.

Techniques for encoded data processing which allow for continuous data processing as encoded data changes.

The recording data is encoded to generate encoded data which is a combination of a mark and a space.
