Anyone else know?
Furthermore, I know there are single transmitter and receiver out there for HDMI. But anyone know if a brand name that produces hi-quality products and sends out to multiple receiver preferably 30ms?
I think you probably know this, but there is no standard for wireless HDMI. Each company uses their own techniques for transmissions and frequencies (as allowed by the FCC in the U.S.). So, the term "wireless HDMI" means a lot of different things.
What you are asking for is basically a multi-frequency transciever since HDMI not only sends from the source to the sink but also gets EDID information and other handshaking from the sink to the source. So each sink on your wireless splitter would need a separate frequency to return the EDID back to the source transmitter. I suppose some type of frequency sharing scheme could be used instead. In any event, it would be a rather complex device for a small market share. I did a quick look on "wireless HDMI splitter" and didn't see anything.
I believe, if implemented properly, the concept of a wireless HDMI splitter would be doable and be permitted under HDCP (just as wired splitters are allowed). But, that would certainly be a niche and probably cost more than using a wired splitter with two so-called wireless HDMI adapters each on a different frequency.
Also, your spec of 30m isn't sufficient since you would also have to account for the number of walls in the way for many of these wireless solutions. You'll also have to check carefully that the video isn't being compressed in order to fit in the wireless bandwidth.
