Unidirectional link standards?

Hey! I wasn't sure where to put this so I'll post it in the networking section. Anyway, I'm interested to know, if there are any existing standards to use for transmitting data over unidirectional links.

Example: Imagine that we want to transmit some data onto the imaginary base on the moon, and we're going to use a laser to do so. We point the laser towards the moon and begin transmitting data by pulsing the laser (turning it on/off with different timings). The moon base has a receiver that is able to detect the laser and capture the light pulses to convert them back to data. Finally, it checks the data for corruption by comparing some checksums present in the data stream. Unfortunately there is no way for the moon base to transmit back to earth to tell them to repeat some transmission because a part of the data became corrupted, but that's okay as this is supposed to be a unidirectional network.

Okay okay, so I'm not going to be transmitting data to the moon for real, but I was wondering, if there are any existing standards i.e. packet structure with checksumming and code or libraries for this kind of data transmission.

Thanks in advance!

The various Digital Television broadcasting standards would be a starting point.
