Web Application Video Ecosystem - Content Specification (CTA-5001-D)
People watch streaming video on many different devices – phones, tablets, computers, TVs, projection systems, stadium displays, and more. This created a nightmare for content creators and streaming media service providers. Not only do viewing devices often have different aspect ratios (ratio of width to height), but they might also have different software, too. The result is that streaming video providers must create and send many differently formatted streams of the same program to reach all the various combinations of playback hardware and software out there. The WAVE Project limits the scope of this problem by identifying a limited number of formats that streaming service providers should be able to use to reach most of their audience. CTA-5001-D enables content producers (movie and TV studios, etc.) to produce a single version of a program that can be viewed on different hardware/software combinations, and it assists content distributors (streaming media companies) in preparing streams that will be compatible with the consumer devices they want to target.
