A good start is to research the different IR remote standards viz Remote control - Wikipedia, the free encyclopedia

ya i had gone through such protocol.SIRC protocol,actully this is my first project on controller based.each bits have both high and low part.also the pulse width of consequtive bits are different.the start bit is big enough.whereas some bits are small .i don't know how to serially recieve such a input from ir sensor
