What is the script that defines the parameters of the IPTV stream? Ideally and stream quality

Question

PHP

For a Web project, it is necessary to process IPTV television broadcast broadcast addresses. It is assumed that the server automatically and cyclically polls the list of addresses on the network to receive stream parameters: video codec, audio codec, image size, video bitrate, audio bitrate, and so on.
Interested in any information in this direction. I read various scientific papers on determining the quality of a video signal, but I did not understand how this can be measured by a software method, especially on the Web.
The option of using the desktop application is unfortunately not acceptable.
