Abstract:
1. An apparatus for processing image data, the apparatus comprising: a buffer configured to receive image signals from one or more sources; a processor configured to encode the image signals to create a group of pictures (GOP) structure, the GOP structure including a header, a data portion, and a trailer, wherein the processor is further configured to encode the image signals to create forward error correction (FEC) capable of correcting errors in the GOP structure, wherein the processor is configured to encode the header to include information pertaining to the relationship between the GOP structure and the FEC; and a driver configured to transmit the GOP structure and FEC, wherein the FEC lags the GOP structure by an amount that allows a device receiving the GOP structure and FEC to utilize both the GOP structure and FEC during a channel-change event in order to decrease a channel-change time.
