Web Application Video Ecosystem – Web Media API Snapshot 2022 (CTA-5000-E)
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-5000-E lists key web browser components used for streaming media that were supported by all four of the major web browsers at the time of CTA-5000-E’s publication. It’s been used to create a test suite that device makers can use to confirm that their products are up-to-date with current web standards at the time of product release.
