Det bliver rigtig spændende at følge hvornår vi får trådløs HD billede / lyd i vores hjem og i hvilken kvalitet det bliver. Men det giver helt klart nogle muligheder for at indrette ens hjem anderledes og f.eks. slipper man for en streambox under tv'et hvis det har indbygget Wireless HD.
Be happy: A new wireless HD video standard guarantees that major brands
including Sony, Sharp, Hitachi, Samsung and Motorola will have
interoperable wireless video streaming. Amimon—the chip makers behind
the "video modem" wireless HD tech we've been seeing on and off for the last few years, and most recently in Belkin's Flywire—is announcing the WHDI consortium with the above members, formed to standardize their wireless HD spec and embed it in member companies' TVs, projectors and HD video sources. The result is a network of HD components, streaming uncompressed 1080p video not just through one room like competing UWB standards, but to and from any source to any TV
in your entire home, with a range comparable to Wi-Fi. Pretty impressive stuff.
just like 802.11n Wi-Fi, meaning it must be able to tolerate the reasonable levels of interference only from other devices that use the same frequencies, and can broadcast at higher power levels than UWB—enough for a range of "over 100 feet." WirelessHD, a third major spec also funded by Samsung and Sony, plus Panasonic, Toshiba, LG and NEC, uses the 60GHz band, and apparently has problems unless the transmitter and receiver are within line-of-sight.
Components will be paired through menu systems using a pass-key, like Bluetooth. The spectrum can hold around six streams of 1080p video at a time, although real-world interference may vary. A likely scenario would be streaming from a WHDI cable box or Blu-ray player downstairs to 3 TVs throughout your house while still having room for HD gaming in the den.The fact that a few heavies like Panasonic are still notably missing
could mean another standards battle is on the horizon. While WirelessHD
already claims a published 1.0 spec, and Monster's UWB product should be out by the fall, the WHDI spec is due to be finalized at the end of the year, with products hopefully popping up in time for CES '09. Stay tuned until then—as one format war ends, another begins.
Og det første tv er på vej
While there have been several other ultra-thin TVs to cheat on size by moving
some of the set's guts into an external box, we're starting to see a
few of the biggies taking advantage of the newly-codified WHDI spec to beam the signal from the external box to the screen wirelessly. Details are somewhat thin
on these new concept Mitsubushi panels, which are 40mm (a hair over 1.5
inches) thick and should reach manufacturing before the year is up. But
their use of WHDI (like these Sharp sets before them) to link the panel to the external tuner box adds an interesting twist to this trend.
Trading a few millimeters shaved off the panel for a big honking box may not seem like a hugely advantageous situation, but WHDI has a range of over 100 feet (into the closet it can go) and allows for seamless pairing of compatible HDTV gear throughout your home, meaning the tuner (or the external Mitsubishi Blu-ray recorder shown next to it) could potentially be linked to other panels in the house. I kind of like the idea of stashing all of my modular source gear in a home theater server room of sorts, leaving only ultra-thin panels to receive the signals visible. That seems to be where WHDI is taking us, although Panasonic (who is not a WHDI member) could have something else up their sleeves. [Tech ON]
