Comcast’s Video IP Engineering and Research (VIPER) team is responsible for delivering tens of thousands of IP linear television channels and thousands of hours of on-demand content to tens of millions of users using a highly scalable, multi-tier software and network architecture.
Adaptive bitrate (ABR) technologies such as DASH (ISO 23009-1) let us originate and deliver video segments as internet objects that are conveniently retrieved, stored, and forwarded using HTTP. With an ABR platform, we can experiment with encoding technologies such as H.264 (MPEG-4 AVC), H.265 (HEVC), and high dynamic range (HDR). We use multimedia presentation technologies to implement an interactive and compelling user experience to our customers, while our alternate content systems require metadata, signaling, splicing, scaling, and reporting that is an order of magnitude more complex than primary video delivery. Comcast continues to solicit, utilize, and share contributions from open source communities, standards bodies, and especially academic researchers for the technologies that make our IP video system possible.
This provides a unique opportunity to view the intersections and the inter-play of the various approaches and solutions developed across these domains to deal with multimedia data types.
