14 DAY TRIAL // In case you were planning for a long wait in order to get your hands on wireless HD transmitters, it seems that Amimon has what you need. Several voices confirm that they have successfully unveiled a wireless high definition interface (WHDI) that can send uncompressed 720p or 1080i video through walls and over short distances without any perceptible degradation of the resulting image.
Amimon says the transmitter will be mass released in 2007 with a sustained transfer rate of about 3Gb/s. The result was obtained by binding two 20MHz channels together instead of using the 5GHz band that carries the draft 802.11n signal (capable of 300Mb/s at best). The resulted bandwidth is sufficient for a streamed 720p or 1080i content but it still lacks the bandwidth to sustain a lossless 1080p transmission. The device developed by Amimon is said to feature a technology called "data segmentation" which can sort pixels according to the information. With the help of these technology only pixels that are important to the picture will be transmitted with the unimportant ones being stopped at the source transmitter. Nice way to lower the bandwidth usage. But does it work?
Apparently yes. A demo that has been watched by the representatives of PC Magazine consisting of a comparison between a HDMI transmission and the wireless one revealed that there are no significant details between the two modes. Amimon's technology really works and they plan to develop it even further in order to sustain 1080p resolutions. The test results also showed that the technology can be used to transmit HD content over a 40 feet distance without any perceptible latencies or pixel errors. The device will also be shown at CES, where it will probably make a very good impression.
