If life ever returns to normal, one thing no one will miss from the lockdown era is the 'TV goldfish'. For over a year, we've watched the disembodied, pixelated faces of contributors to live TV mouth their words out of sync with their audio, gulping away as if in a private fish tank. This isn't the exception for internet video, it's the norm.
John Day is one of the internet's greybeard founding fathers. For a decade he has been advancing a set of improvements to the current mainstream internet protocols. His proposals – called RINA (Recursive Internetwork Architecture) – revisit and build on Louis Pouzin's founding concept of datagrams (data packets). Simplifying these features allowed the original inter-networking protocols (IP) to get out of the door in the 1980s and 1990s, and allowed for the rapid growth of the internet. But the current system we have – TCP/IP – is holding back new innovation.

Blocks on the screen and skipping audio are caused by packet loss. Whatever interference caused it doesn't care if they are video or audio so using two streams wouldn't really help, since both streams would still experience packet loss.

True, but the emphasis should (for these types of things) ALWAYS be on audio, because the video is usually superfluous.

Also, making audio redundant is cheap. If the channels are bonded, redundancy is too expensive. I think the difference in bandwidth is such that you could do a simple tripling of the audio packets, use a "voting" system to throw out loss and not consume too much bandwidth. I think the more sophisticated approach is to prioritize a low sampling rate for redundancy. I think cel phone providers to this, which is why you sometimes hear people transition to an echoey "robot voice" for a few seconds.
