Every live channel starts as a source feed that gets captured and then run through an encoder, a system that compresses raw video into a much smaller file size for practical transport over the internet. Most modern services use HEVC compression, which needs roughly half the bitrate (data rate) that the older H.264 format required for the same picture quality on screen. That's why a well-run HEVC stream at 1080p can look every bit as sharp as a much larger H.264 file while using noticeably less of your available internet connection to deliver that same picture to your device.

After encoding, the stream moves through a content delivery network — a layer of distributed servers positioned specifically to shorten the physical distance between the source and wherever you happen to be watching — arriving at your device as small segments, typically around six seconds each in length. Your player app buffers a few of these segments ahead of actual playback, which is exactly why a stall lasting longer than that buffer window shows up on screen as a visible freeze rather than as a gradual, smooth slowdown you might barely notice happening.

IPTV as a technology is just television delivered over an internet connection instead of a coaxial cable or a satellite dish pointed at the sky — the transport method itself isn't the legal question anyone actually needs to answer. Licensing questions attach specifically to what a given service does with its source content, and that genuinely varies from one provider to the next. A VPN hides your traffic from your internet provider but doesn't change what any particular service is actually licensed to show, so it isn't a legal fix for anything related to content rights.

A channel's EPG (electronic program guide) data comes from a separate field inside the playlist source, and when that specific field gets left blank for one channel, that single channel loses its guide while every other channel on the exact same playlist keeps working normally. That's a distinct, narrow technical cause — a missing tag on one individual entry in a larger file — not a sign that the whole content pipeline behind the service has failed or that something bigger is broken across your entire subscription. Reporting the exact channel name to support usually gets that one entry corrected faster than restarting the app or the device ever will.
