YouTube has announced that it will be showing off its new 4K video streaming capability at CES 2014. YouTube will be showing the streaming video off in the LG and Sony CES booths. The YouTube 4k service will use Google's in house developed VP9 codec reports HDTV Test.
That codec allows the streaming of 4k video without needing lots more bandwidth. That means the video will look better even on slower web connections. YouTube also notes that the VP9 codec will reduce the data needs for streaming full HD video roughly in half.
Google tried in the past to get its own video codec adopted as the default, but that never happened. Things are different with VP9, Google currently has 19 hardware partners signed up. That means that VP9 is expected to become the default 4k video streaming codec out there. YouTube is open to using H.265 codec as well in the future.
