You are probably better off searching the Interweb thingy about that ...... much as we like to help, re-inventing the wheel isn't part of the job ;)
But here's a brief intro:
For Satellite, Platforms like Sky and Freesat carry all the EPG data on a dedicated "Default" Transponder.
Related reception equipment then polls the data stream and populates the allocated local memory.
Don't know about Sky, but Freesat archives the data for access via Schedule then Red, but that can be out of date. Pressing Guide gets you bang up to date data, but takes half a minute or so to refresh.
Edit: Actually, this also relates to your question about Channel Icons on another, on-topic topic. One of the occasions when the Freesat Default Transponder is accessed is at 03.00 each day, when not only is the EPG updated, but also stuff like Channel Icons, Thumbnails for stored Recordings, Added/Removed Channels etc.
