Abstract-Digital Subscriber Line (DSL) network access is subject to error bursts, which, for interactive video, can introduce unacceptable latencies if video packets need to be resent. If the video packets are protected against errors with Forward Error Correction (FEC) calculation of the applicationlayer channel codes themselves may also introduce additional latency. This paper proposes Low-Density Generator Codes (LDGM) rather than other popular codes because they are more suitable for interactive video streaming not only for their computational simplicity but also for their licensing advantage. The paper demonstrates that up to a 4 dB reduction in video distortion is achievable with LDGM Application Layer (AL) FEC. Telemedicine and video conferencing are typical target applications.

“…As in [15] an LDPC code with a block length as low as 170 was found to be competitive with RS codes in error recovery terms. Because not all packets could be recovered even at low loss rates, the ability to retransmit was recommended, which is also the recommendation of [28].…”

Interactive video, due to the need to maintain synchronization, has strict latency requirements. Video streaming to residential users is also constrained by the error bursts that are a feature of Digital Subscriber Link (DSL) access. This paper examines the video response to unlicensed Low-Density Generator Matrix (LDGM) channel codes that combine reduced computational latency and small block sizes with reasonable recovery properties. The paper demonstrates that up to 4 dB gain in video quality is achievable with LDGM Forward Error Correction (FEC) at the Application Layer (AL).
