SVC

Acronym:Scalable Video Coding

Scalabe Video Coding emerged in the mid-2000s as a way to pre-define a number of consistent bitrates and resolutions for H.264 content. Some implementations allow up to 27 different pre-defined bitrates and resolutions. In many ways, Adaptive Bitrate (ABR) versions from Adobe and Microsoft (fragmented MP4) as SVC "lite" but ABR gained in popularity due to the availability of ABR-capable players, while SVC-equipped players lagged. SVC offers significant benefit when it comes to network traffic shaping, so expect to see a derivative of SVC emerge around H.265 or future compression standards.
