A low power wireless infrared transmitting system is presented for transmitting video signal. Using anti-fuse FPGA devices as Encoding/Decoding (ENDEC) core
and high speed serial infrared transceivers as transmission module in this system
the run length limited (RLL) code is deployed in FPGA as a channel ENDEC module to work together with other modules
including IO buffer
serializer/deserializer
cycle redundancy checksum and scrambler/descrambler. Combined with AD/DA interface circuits
these modules compose an integrated demonstration system
in which the two-channel composited video signal can be orderly captured
encoded
emitted
decoded and displayed.The transmitting bandwidth of the system is up to 16 Mbit/s
but the power consumption of the infrared emitting module is low to 500 mW. Therefore it can be used as a wireless interface between the video capture equipment and the video processing system.
