A/V Transmitter

The goal of the project is to develop a transmitter board transmit wireless audio/video via a 2.4GHz link using FHSS protocol and MJPEG compressed video. The hardware design, PCB layout and prototype boards need for development will be provided. Selection of the processor to be used is flexible. TRANSMITTER BOARD FUNCTIONAL SPECIFICATION 1) Video Input: Composite NTSC to BT.656 Video Standard. Typical IC: TI TVP5150. The processor must initialize and interface this type of device. 2) Audio Input: 16K Sampling ADC: Typical IC: TI: PCM1802. The processor must initialize and interface this type of device. 3) Digital Output: RF Transceiver: Typical IC MuChip MV400. The processor must initialize and interface this type of device. 4) Processor firmware functional requirements: - The processor must initialize and interface the video input IC. - The processor must initialize and interface the audio ADC - The processor performs MJPEG compression on the incoming digital video data stream. - The processor combines the compressed video and audio data into a serial data stream to be transmitted via the serial RF transceiver. - The processor must control the RF transceiver per the FHSS Protocol to meet requirements of FCC CFR 47 Part 15 Sect. 247. This basically involves controlling the carrier frequency hopping and dwell times. The performance targets are to transmit 640x480 images at ~30FPS with reasonable quality (my guess is the MJPEG compression ratio has to be ~ 20:1). Note: A second project to develop a matching receiver will follow.
