Why do HDMI cables have such high bandwidth capability when most of the content we watch is usually at a much lower bit rate?
In: Technology
To add to what u/schorhr said, the actual data rate for a 60fps 1080p video stream is somewhere around 4 or 5 gigabits per second through an HDMI cable. 60fps 4k is four times that.
If you’re watching a DVD/Blu-Ray or streaming video, the video source is handling decompression and each frame is sent over the cable as an uncompressed image. If you’re playing a video game then the video card in your computer or console is sending each frame uncompressed pretty much as soon as it’s done rendering it.
