Per stream, budget 15 to 25 Mbps for 4K and 5 to 8 Mbps for 1080p. Those are sustained figures, not burst speeds from a test site, and they multiply by simultaneous connections rather than averaging out. Three 4K streams at once means 45 to 75 Mbps held steady while the rest of the house is also online. HEVC changes the arithmetic: the same picture at roughly half the bitrate, so a 4K stream can land nearer 12 Mbps on a device that decodes HEVC in hardware. The number to size against is your worst evening, when local congestion is highest, not the speed on your bill.

1. 1Multiply by concurrent streams, never average them
2. 2Three 4K streams at once: 45-75 Mbps sustained
3. 3HEVC brings the same picture at roughly half the bitrate

Resolution is decided at the source, upstream of any subscription. A 4K IPTV subscription does not upscale a feed that was encoded at 1080p or 720p, and no player setting invents detail that was never sent. That is why a catalog can be genuinely large and still mixed: some feeds are 4K, plenty are 1080p, and older material is exactly what it was shot on. A quick way to separate a source limit from a delivery limit is to compare a 4K on-demand title, which was encoded once and sits on storage, against a live channel at the same moment. If the on-demand title is sharp and the live feed is not, the constraint is the live source or the path to it, not your screen.

1. 1No subscription upscales a 1080p source into 4K
2. 2Compare a 4K VOD title against a live channel to isolate the cause
3. 3Mixed resolutions are normal in any large catalog

About 7 GB an hour, which turns into real numbers fast. Three hours a night at 4K is roughly 21 GB a day and about 630 GB a month from one screen. The same three hours at 1080p is closer to 270 GB. On a 1.2 TB cap, one heavy 4K viewer plus a second household stream can reach the ceiling in a month, so this is worth checking before assuming 4K everywhere is free of consequence. Two levers help: pick the 1080p variant of a channel for background viewing, and prefer devices with HEVC decoding, which cuts the bytes roughly in half for the same picture.

1. 14K: about 7 GB/hour. 1080p: about 3 GB/hour
2. 2Three 4K hours a night is about 630 GB a month
3. 3HEVC playback cuts data roughly in half

An IPTV 4K subscription splits responsibility in a way cable never had to. Yours: a device with hardware HEVC decoding and an HDMI 2.0 or later path to the panel, which covers Firestick 4K, Apple TV 4K, current Android TV boxes and recent Roku models. Yours also: 5 GHz Wi-Fi or, better, Ethernet, since 4K sits at the bitrate where 2.4 GHz starts failing in the evening. Ours: the feed, the server capacity behind it, and what happens when thousands of people open the same stream at once. Some stalling is oversold capacity on a provider side and no player setting touches it, which is why an uptime figure matters. Ours is 99.99%, about 53 minutes across a year.

1. 1Hardware HEVC decode and HDMI 2.0+ on your side
2. 2Ethernet or 5 GHz Wi-Fi at 4K bitrates
3. 3Provider capacity is not something a device setting can fix
