How is online television arranged?

Question

Python

Sorry for the too general question, but I don’t know much about this area in order to search correctly, and Google basically throws it out on ready-made sites.
Actually, the question is, how are sites like rus24.tv/rossiya1.html arranged
, what technologies do they use, how are things with copyright, where does the content come from ...?
Thanks in advance for a kick in the right direction :)

Answer 1

It works through IP-tv, RTSP or other protocols.
Content is taken in different ways:
1) From the same sites of television channels, they usually broadcast their own channel to their site.
2) Digital TV is connected at home (many providers now broadcast over IP-TV) and simply relay it to their server from where they are already distilled anywhere further.
3) They connect TV at home, put a bunch of TV tuners, collect streams to their server and transfer it further anywhere.
The most reliable but at the same time costly 3rd method. The 1st method will break when the site\api\server is updated, etc., you will have to study again what has changed. The 2nd method is not very reliable because (purely personal impressions) providers push IP-tv very poorly and there are always some problems, the picture will freeze, the sound will disappear, etc.
For example, you can dig into the official page with the channel Russia 1 live.russia.tv/index/index/channel_id/1
From your link is also an interesting example of how they tried to link to the playlist:
Answer after wildly complicated decryption " 62.210.127.74/hls/01/index.m3u8?mkll1463510293 "
Copyright in most cases is very bad.

Answer 2

Find the source and rebroadcast. In the event of a collision, as a rule, the channel is turned off.

Answer 3

Information, on TV or in official websites, is taken and relayed to their website.
You can also stream on twitch (or other sites), rebroadcast.
But you don't have to do that !

Answer 4

For example, I used to have a TV tuner on my PC.
Through the software, I could watch absolutely all the channels that went via cable to the TV in the living room.
Your site uses the Uppod player, with the source file:
Most likely takes links from direct sources, i.e. for example, from the site of the first channel, etc.
Or maybe it somehow relays through this same TV tuner from a PC / server in a certain format to a playlist (this is the file that is encoded in txt), after which Uppod takes the broadcast from txt and converts it to what we see.
