Patent Images

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; 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.
