Abstract
In a system that uses inter-frame coding to compress blocks of data for transmission from a transmitting device to a receiving device, and sends acknowledgment signal back from the receiving device to the transmitting device, the receiving device packs decoding-error information about multiple blocks into each acknowledgment signal. The transmitting device unpacks the acknowledgment signal to obtain the decoding-error information, and uses this information to keep from performing inter-frame coding with reference to data that the receiving device was unable to decode. The bandwidth saved by packing information about multiple blocks into each acknowledgment signal can be used to enhance reliability by repeating the information in multiple acknowledgment signals.
