Several months ago, I saw a portable television that Sharp had introduced that utilized 802.11b wireless to transmit a digital signal from a base unit to the television. At first, this seemed similar in operation to the audio/video wireless sending units that most everyone is familiar with. The picture quality, however, was crystal clear. Most of the other audio/video sending units I have seen transmit a 'fuzzy' analog signal, especially as you add distance or walls to the picture. The Sharp, utilizing an 802.11b digital signal was rather impressive. However, the price was rather high, I thought, for what it was. What I would like to do is either purchase or somehow manufacture a device that will take video and or audio signals, encode them and transmit them utilizing 802.11b or 802.11g wireless protocols to another receiving unit that could then be connected to a regular television. I know I have seen home media devices that will transmit files from your computer, etc. but is there something that will encode MPEG streams from sources on-the-fly and transmit them like the Sharp unit does?
