ERROR PREVENTING DEVICE FOR MULTIMEDIA SYSTEM Russian patent published in 2004 - IPC

FIELD: preventing errors in decoding plurality of information bursts.

SUBSTANCE: device has transmitter incorporating burst buffer for generating primary information bursts using punched convolution code compatible with transmission speed as well as receiver incorporating buffer linked with transfer channel and designed to store information bursts received from transmitter, and decoder designed to decode one or more information bursts saved in buffer; decoder functions to decode combination of information bursts in response to error generated in them during decoding of one or more information burst, and information transferred earlier is obtained from any information burst or from combination of information bursts saved in buffer; the latter transfers message in response to error generation during decoding of combination of information bursts for automatic retransmission of request and burst number over transmission channel to transmitter, and the latter transfers other information bursts of their plurality.

EFFECT: improved data recovery and enhanced capacity of transmission-system channel.
