It's all about bandwidth. Cable TV providers simply don't have enough bandwidth to deliver a 1080p signal where every frame contains the whole picture at 60 frames per second. So, it sends 1080i signal, where only half of the picture is contained in every frame.
Yes, it seems lately that in auto mode, it reverts to SD, even though I had set it to 1080p, and the signal was definitely at least 1080p. Sounds like a dirty way for Youtubetv to get us to buy the 4k option, by ruining everything else into SD, unless you go back and put each channel into HD every time.
youtube 720p or 1080p signal
Still, by even offering some channels at 1080p, YouTube TV vaults over its competitors. Hulu with Live TV only just started streaming some channels at 1080p. Sling doesn't have detailed information about its streaming resolution, while Philo streams live TV at 720p and on-demand at 1080p.
The 1080 and 720 in 1080p and 720p stand for vertical screen resolution, or height, in pixels. The more pixels there are in an image, the clearer it will be. As such, a screen resolution of 1920x1080 (two million pixels when multiplied) should appear twice as sharp as a resolution of 1280x720 (fewer than one million pixels). Meanwhile, the p in 1080p and 720p stands for progressive scanning, which updates full frame images more quickly than traditionally interlaced content.
HD DVDs contain 720p content and sometimes 1080p, while all Blu-ray discs contain 1080p content. Regular DVD quality can vary considerably, with some displaying content at a resolution lower than 720p, such as 480p. Moreover, there are still DVD players around that only carry support for up to 480p or 480i, meaning a viewer cannot get the full experience of any high-definition DVD they insert into the player.
Netflix typically streams at 720p, but with the release and expansion of what it calls "Super HD," users are able to stream more and more content at 1080p quality with a high-speed internet connection. Apple TV allows users to choose between 720p and 1080p streaming. DirecTV displays a "1080pHD" logo on 1080p pay-per-view content, and all their latest DirecTV Cinema content is in 1080p. On YouTube and Vimeo, high quality videos often allow for 720p or even 1080p streaming.
Screen resolution can be especially important in video gaming. Because there are more pixels in 1080p, less anti-aliasing is required for a smooth visual experience. This means that 1080p will not only likely look better than 720p, but will lead to a better gaming experience overall, as anti-aliasing can slow down a console or computer.
When you play a YouTube video, the site offers up as high a video resolution as your bandwidth appears to support for fluent playback. At the lower resolutions that YouTube makes available to viewers -- 240p and 360p -- you see a small video frame size. To access the best video quality you can view, you need the bandwidth necessary for high-definition 720p or 1080p footage. The higher the resolution, the more pixels the video image contains and the better it can reproduce the details of a sequence or movie. When you display a video full screen, however, the image enlarges enough that it can become blurry because you now see it larger than its actual size.
When I go to youtube itself, playing 720p video in a 720x480 window looks better than 480p at the same size. I want to play 720p in a 720x480 window (downsampled better quality). There is no good solution yet afaik.
SD resolution is standard quality resolution. The resolution often refers to a pixel height of 480 in a single image. The frame is more detailed than that of a 360p, 240p, or 144p image , but less detailed than one that is 720p or 1080p.
Once you know your upload and download speeds, you can choose a stream quality. For livestreaming, we are concerned with the upload speed (measured in megabits per second or Mbps). To stream in 1080p (Full HD), you will want at least 6 Mbps upload speed. To stream in 720p (HD), at least 2 Mbps. For 540p (high), use at least 1.2 Mbps. A 360p (medium) stream needs at least .8 Mbps. And lastly, a 270p (low) stream requires .5 Mbps upload.
High Definition (HD) resolution is rated at 720p and 1080i (interlaced scan)/1080p. The superiority of this resolution over standard definition is dramatic, and it requires at least 5 Mbps of bandwidth to play smoothly and without interruption.
In the most basic terms, HD Ready TVs (and set-top boxes) are capable of displaying 720p video, which is 1280x720 pixels. Full HD TVs and boxes can show 1080p video, which is 1920x1080 pixels. The HD Ready standard came about in Europe around 2005, so that people could be sure they were buying TVs that actually supported HD.
In the US, HD Ready for a TV means that the display can output 720p images. In most cases, this also indicates that the TV has a built-in digital tuner, which is necessary to accept digital TV broadcasts (which have largely replaced analog signals). This same HD Ready logo is also printed on several projectors, computer monitors, and other devices, which don't have a tuner.
TVs show video as a series of lines; resolution is simply the amount of pixels that make up a display, both horizontally and vertically. The shorthand numbers used for resolution (720p and 1080p) represent how many vertical lines can your TV display at one time.
1920x1080 resolution (1080p) means that there are 1920 pixels horizontally and 1080 pixels vertically. 720p resolution is 1280x720 pixels. Having a higher resolution results in a sharper image, because there's more information on the screen at once.
A 1080p ("Full HD") TV can display progressive scan HD signals from video game consoles, Netflix streaming, and similar. These TVs can also show interlaced signals, but since the process of deinterlacing isn't perfect, you can sometimes spot imperfections.
Remember that video will play at the lowest resolution supported by any device in the chain. For example, if your TV is Full HD (1080p), but your set-top box is only HD Ready (720p), your TV will show 720p video. A PlayStation 4 capable of outputting in 1080p won't be able to show that 1080p video on a 720p TV.
720p resolution has become the default minimum for nearly every display device. If you're buying a TV, monitor, projector, or anything like that, it will almost certainly support 720p video at least. Unless it's extremely cheap, chances are that it supports 1080p as well; the Full HD tag lets you know for sure.
In general, unless you're looking to spend as little money as possible, we don't recommend buying any display that's under 1080p. While 720p is still referred to as "HD," 1080p is the HD standard in most people's minds. It's used for Netflix streaming, Blu-ray discs, game consoles, and similar.
Hi, Lately I have been unable to watch any youtube content using the bluecurve tv. Anytime I try to watch anything in HD (720p) the screen goes all fuzzy but when I drop the quality down to 480p it seems to play perfectly fine. This just randomly started to happen and I can't seem to fix it. I have done several restores and resets on the bluecurve tv box and nothing seems to work. Anyone else have this problem or have any solutions?
YouTube TV supports up to 1080p resolution at 30 frames per second, and up to 720p at 60 frames per second. However, not all channels will provide that quality. Video quality has been a common complaint among streaming viewers, including YouTube TV subscribers.
3. Set up 4K TV settings properly: Your 4K TV should be by default set in 4K mode and show 4K quality if your video contents are in 4K resolution. But what if you play 1080p/720p or lower resolution videos on 4K TV, how to make your picture quality show better without fuzzy errors? Each 4K TV brand including LG, Samsung, Sony, etc. gives you official suggestion to adjust best picture settings on 4K TV to get the best effects, so you can go to their official sites to follow the guide. Commonly, your 4K TV settings should be as follows to let your video playback be close to 4K as much as possible:
6.The bandwidth is strong enough for TV broadcasting: Though most the live TV broadcasts are in 720p or 1080p, there are some 4K shows available. Especially for the IPTV streaming, the network connection should be strong enough as IPTV streaming automatically changes the video resolution based on the network condition.
720p improved on the 480i and 480p of standard definition terrestrial television (SDTV). In TV signal specifications, like 720p, 1080i or 1080p, the numeral indicates the number of horizontal lines in the complete raster. The p in 720p stands for progressive scanning, in which each scan displays every line in the image raster sequentially from top to bottom, so that the entire image is refreshed with each scan. 2ff7e9595c
