| well most of the remotes used today follow RC5 coding, a type of manchester code.Connect an IR receiver TSOP 1738 with its associated circuitry mentioned in its datasheet to one of the external interrupts of 89C51RD2. i don't know of any C program but assembly language decoding program is available on the internet.

| Using an external interrupt plus 1timer, you can decode it by start and stop and read timer data inside an external interrupt routine.
