Abstract

A system and method for providing VOD / NPVR content in a switched digital video network using unicast adaptive bitrate (ABR) streaming. In one implementation, upon receiving a notification from a back office pursuant to the VOD session request from a subscriber station (e.g., a set-top box or STB), a bandwidth pipe modeling process is operative to model a bandwidth pipe corresponding to each edge QAM device configured to support VOD sessions for selecting a particular edge QAM device that can best accommodate the requested VOD session. Bitrates of UABR streams of existing VOD sessions of the selected edge QAM device may be adjusted in order to accommodate a particular UABR stream at a chosen bitrate for the requested VOD session. UABR allocations of the selected edge QAM's bandwidth pipe may be effectuated for the existing VOD sessions and the requested VOD session as needed. A response message including one or more session frequencies, if the session request is accommodated, may be transmitted to the requesting subscriber station.

Description

technical field [0001] The present disclosure generally relates to communication networks. More particularly, and not by way of limitation, the present disclosure relates to systems and methods for providing video on demand (VOD) content in a switched digital video network using unicast adaptive bitrate (ABR) streaming. Background technique [0002] Switched digital video (SDV) technology, also known as switched digital broadcast or SDB, allows cable television systems to decide which channels should be streaming at a given time without allocating bandwidth for all channels to stream at the same time. It provides some bandwidth dedicated to static or guaranteed channels (which will stream regardless of network state) and other bandwidth dedicated to swapped channels (which can appear and disappear in response to channel change requests / responses and network conditions). In delivering content to consumers, traditional SDV architectures rely on binary operations, ie a bandwid...
