Pay TV services and adaptive bitrate (ABR) streaming
As subscribers’ demand for non-stop video content grows, Pay TV providers have turned to Adaptive Bitrate (ABR) streaming to deliver programming over Internet Protocol (IP) networks. Though unicast ABR supports delivery to devices such as tablets, phones and laptops, unicast ABR consume significantly more bandwidth for each incremental video stream viewed. This can choke video delivery networks and cause the video quality to degrade.
Multicast ABR offers service providers a way to optimize ABR video bandwidth usage, minimize exposure to unicast traffic spikes during popular live TV events, improve video quality, and ease the transition to IP video.
