Infra-red : Don't rebuild IrDA unless you are doing something really simple
Simple solution: just hook an IR transceiver to a USART
Complex (or at least not simple): MAX3120 - Single chip IRDA modulator: hook one end to USART and the other end to IR transceiver, 115 kbps @ 1 meter
4meg IRDA Edit
Use the LT1328CMS8 4meg IrDa chip for data reception. Do Mpeg4Compression down to 4meg on a CctvCameras stream transmit 500m to a central node via RonjaChips IR transmitter. Main advantage of the 4meg Linear chip is the low cost of $3 and no spectrum pollution.
115kbit/s IR transceiver Edit

Measuring 1.9 mm high, 3.1 mm deep, and 6 mm long, the TFBS4711 transceiver is designed for short-range wireless applications using infrared connectivity. It features a data rate of 115 kbits/s. The device will find homes in cell phones, PDAs, digital cameras, Point and Pay applications, or in any other situation where designers must find space for connectors, buttons, antennas, or displays required of other wireless technologies. Engineering samples are available now.
