Video Conferencing with guaranteed bandwidth for high resolution video and full-quality audio

I am looking for an expert to advise me on how to get the right video conferencing system. The first requirement is that it can dedicate bandwidth for 720p (or ideally 1080p) video and audio with full frequency range and limited compression. In addition, it would ideally have functionalities in line with the best systems. It could be Zoom rooms, Zoom Group HD, Adobe Connect, Cisco - or any supplier who would allow me to buy a premium, guaranteed quality. I need it to connect to my video studio (with quality video and audioI, i.e. I do not need hardware. It should accept up to 20 participants. They do not have to be in max resolution - only my studio. But it should be 100% interactive, without latency. I am looking for someone who already has done this before, who can advise me on the supplier, and can install any software on my PC - and set it up for max quality.
