Abstract
An input image signal is coded by an encoder to be outputted as a basic code string, and the basic code string is delayed by a code-string delay circuit for a predetermined period of time to be outputted as an additional code string. The basic code string is synthesized with the additional code string by a code-string synthesizer to be outputted as an output code string. Thus, there is provided an image data coding system which can quickly restore data even if the data is lost due to error and in which the increased code amount is less than the cycle refresh and the error correction.
Claims12
A moving-picture decoding system comprising:
- code-string dividing means for dividing an input code string into a basic code string and an additional code string, said additional code string including a portion or all of the basic code string;
- basic code decoding means for decoding the basic code string;
- and
- additional code decoding means for decoding the additional code string.
A method of decoding a moving-picture, comprising:
- dividing an input code string into a basic code string and an additional code string, said additional code string including a portion or all of the basic code string;
- decoding the basic code string;
- and
- decoding the additional code string.
A moving-picture decoding system comprising:
- a code-string divider configured to divide an input code string into a basic code string and an additional code string, said additional code string including a portion or all of the basic code string;
- a basic code decoder configured to decode the basic code string;
- and
- an additional code decoder configured to decode the additional code string.
