Notes
  • Streaming video data over a digital Radio Frequency (RF) link operating in the ISM band (e.g., 2.4GHz/​5GHz) is known to be a challenging task that has recently captured consid- erable industry attention. Various sources of air interference cause packets to be dropped despite retries and forward error correction (FEC) schemes found either at the transport or video encoding layer. However, there is an industrial interest for a concealment technique suitable for wireless cameras, featuring very low processing power. This article presents therefore an alternative to the conventional wisdom: a novel video packet loss concealment scheme that operates after the decoding/​ decompres- sion of a truncated video bitstream. The approach is therefore codec-independent and does not incur the overhead associated with typical FEC techniques. We demonstrate recovery up to 20dB using a real-time implementation of our proposed approach.
