Software Implementation of Forward Error Correction for IPTV Terminal Devices

Internet Protocol (IP) TV delivers scheduled TV programs and video on demand over IP networks, allowing such services to be provided at low cost. On the other hand, packet losses and delays are inevitable in IP networks, degrading audio and video quality.

To solve this issue, Toshiba has developed a practical technology for implementation of forward error correction (FEC) software for mid-range and low-end TV sets and PCs. Our algorithm and its implementation are platformindependent and adjustable for each product, without the need for any additional hardware.

This algorithm reduces processing time by 40% and memory usage by half, which is achieved by integrated processing of delay compensation, reordering, and loss recovery.
