Streaming uncompressed raw video over ethernet for TV production. It's still commonly done over dark fiber but people are slowly migrating towards IP. A single uncompressed 4K video stream is over 12Gbps, 1080p is 3Gbps and obviously when you're producing content you have a few of these running alongside each other (multiple cameras, feedback, big screens etc... Think something like the world cup or superbowl). It quickly adds up to a tremendous bandwidth. On top of that it needs very low latency and jitter to keep all the streams synchronized.
- tatersolid 9y agoWhy would anyone stream uncompressed raw video? Even MPEG-2 at q=1 with no B-frames is about 1/10 the size, visually lossless, and adds only a few ms of latency.
- e12e 9y agoLooks like for editing you're looking at up towards 3.5 gbps per camera, not sure how much to add for sound. So a three camera production could easily push over 10 gbps. Pushing past 100 seems to be a bit of a stretch. Maybe for 3d?
