Is this simply because everybody is connecting to a stream to watch a big moment in a game all at once? It seems like whenever I watch the game and there’s a critical moment the screen freezes up. Luckily the provider has six or seven streams for the game but they all seem to do it from time to time. Is this just one of the downsides of IPTV?
I did some digging around this a couple of months ago. From what I understood, most codecs work by updating the pixels of the previous frame - instead of redrawing the entire frame (which could happen 28 or more times per second) the codec will only update changed pixels.
When such big moments happen, example when a goal is scored in a soccer match, a lot of things happen simultaneously (confetti, spectators cheering, etc). This means there will be a spike of data that needs to be sent and updated which could lead to buffering ( if the server is not able to send this data in time) or chopping (media device not able to keep up with the changed data)
