Just what the world needs: another consortium promoting a wireless technology for the transmission of HD content in the home. The latest is the Wireless Home Digital Interface (WHDI), launched today by Sony, Samsung, Hitachi, Motorola and Sharp. WHDI's technology comes from Israeli company Amimon. It uses the 5GHz band to transmit uncompressed 1080p video, audio and control signals around the home from multiple sources to multiple receivers. All this data is beamed at up to 3Gb/s.Amimon claimed WHDI's range is 30.5m. It can go through walls and has a latency of less than a millisecond. The technology was developed specifically for video, Amimon said. It "takes the uncompressed HD video stream and breaks it into elements of importance. The various elements are then mapped onto the wireless channel in a way that give elements with more visual importance a greater share of the channel resources".

Based on what? Blu-ray? That's probably the only major format that Sony designed that ever became the mainstream. They've certainly had more failures/misses than successes - UMD, Minidisk, Memory Stick Duo/Pro (admittedly these are used often enough, but SD and SDHC are vastly more popular), I believe they even had a hand in Betamax.
yet they claimit's uncompressed. Sure it may be uncompressed, but doing that will effectively achieve the same degradation and artefacts as compression....

Also, how the hell are you supposed to define "importance" in a video stream?
of course VC1 HD video is allready compressed, so a properly implemented wireless HD stream in a BD player should be able to stream it directly , granted you'd have to move the dcoding to the TV/receiver device.
AVC is computationally much more expensive than VC1, but it HAS to be supported, as it is also a standard.
So, putting the decoding on the end device might cost more.
However, those companies backing it up are new. What i don't unsderstand is why we need another standard. Instead, effort should be put to work on standardization of current standards...Talk about encoding alone. There are many profiles, bitrates, etc... One can't choose a profile along with an application because maybe some time from now those video files won't be even played or supported anymore.
This WHDI seems good, but there is already pre-N gear that can keep up with streaming HD content wirelessly.
