Industry Trends and Challenges
The delivery of live, on-demand video over IP networks continues to rise due to the increasing number of people watching Internet video over smart mobile devices and Internet-enabled set-top boxes.
There are two main types of video streaming. Transitional video streaming delivers video to end users via RTP/RTSP over a digitized cable television network; adaptive HTTP streaming delivers video over a telecommunication network. The latter is becoming more and more popular due to its ability to adapt video streaming to fluctuating network conditions. The emerging adaptive HTTP streaming technologies include Apple HTTP LiveStreaming (HLS), Microsoft Smooth Streaming, Adobe HTTP Dynamic Streaming (HDS), and MPEG Dynamic Adaptive Streaming over HTTP (DASH) .
The main challenges facing streaming transcoders include ultra-HD transcoding to improve existing high-quality video delivery and multi-screen and multi-rate transcoding to cater to different screen sizes and network bandwidth. All of these challenges require a high-density, high-performance video transcoding pool.
