Obviously depending on the satellite or cable provider, the bit rates are normally kept high when exported from the station. But also keep in mind that all that data has to get crunched down and fired off into outer space, or shoved in a cable a sent across a long distance. It's all about efficiency. | |

From a TV station perspective, they usually aim for the best that they can provide. (Unless it's a local station using OTA, and you're getting free TV, then the station would be the one making that call). | |
| Jul 21, 2017 at 18:12 | comment | added | user54031 | Then you must have a lot of hard drives @JorenVaes! Sorry too hear that your TV experience was that bad! The TV stations like the larger files because it gives them a bit of freedom. For example, if they can provide an internet streaming solution at a higher bit rate than they can provide on OTA TV, or satellite, having the highest quality file lets them compress and convert as they need to. And yes, TV stations usually have a lot of storage (usually between 250 TB - several PB), which is a very worthwhile investment. | |
| Jul 21, 2017 at 18:03 | comment | added | Russell Borogove | In set-top cable installations, the provider will reallocate bandwidth across channels dynamically -- spending more bits on the big game than on daily soap operas one day, then spending more bits on the season premiere of a big drama than a little league game the next, for example -- so it makes sense to distribute the highest quality version even if it might be re-encoded at a lower quality for broadcast. | |

Added some info on bit rate and corrected some typos.

The bitrates I seem to get when I look at TV are very low, and they are one of the reasons I stoped watching TV, prefering to wait untill I can get a blu-ray version of the content. If you are going to display a heavily compressed version, why don't you just store it as such? I imagine with the amount of redundancy and such storing a 32GB file will take a lot of space. | |

Expounded upon some specifics, corrected some errors.
