ITU-T H.701 PDF

The ability to deliver high level of service quality to users is an essential aspect of IPTV services, and thus captured in many IPTV-related requirements. As IPTV services can easily be degraded if the media decoders are exposed to impairments such as packet losses, mechanisms are needed to reliably deliver good IPTV service quality in the presence of such defects.

This Recommendation integrates error recovery in the IPTV architecture, describes specific mechanisms and discusses the applicability of the mechanism to IPTV services and network conditions, and provides recommendations and guidance on their use.
