[Solved] Is “multiplex” a proper name for bit concatenation? (self.programming)

I don’t remember the first time I saw this word but I suspect the word multiplex is not the proper one. How would you name this:

Shot name is multiplexed as 15:17, where:
* The first 15 bits stores the sequence number.
* The last 17 bits stores the shot number.

Thanks in advance!

EDIT: Thanks all! So it seems packed is the proper word. With pack/unpack being the name of the process.

I've seen this referred to as a "packed" field in some cases.

Yeah that’s a good suggestion. A common way to refer to low-level memory structures e.g. C structs. Bit packing, padding, and alignment.
