R 15 Bd 720p Or 1080i [PATCHED]


While 1080i has 1080 lines of resolution, 720p has only 720 lines. The "i" and the "p" in these resolutions stand for interlaced and progressive scanning, respectively. While some customers will not notice a significant difference between the picture quality of 720p and 1080i, progressive scanning offers an objectively superior picture, especially on newer LCD or LED TVs built for higher resolutions and progressive scanning.


1080i represents 1,080 lines of resolution scanned in alternate fields consisting of 540 lines each. 1080i is the most widely used HDTV format, and has been adopted by many television broadcast, cable, and satellite outlets as their HDTV broadcast standard.


720p represents 720 lines of resolution scanned sequentially. In other words, all lines are scanned in progressively, providing a more detailed high definition video image compared to interlaced display technology of the same resolution. Progressive scanning reduces the need to prevent flicker by filtering out fine details, so spatial (sharpness) resolution is much closer to 1080i than the number of scan lines would suggest.


Video Up-conversion: When connected to your TV using the HDMI output the BD-P1500 scales the output of a standard DVD signal to HD-compatible 720p, 1080i, or 1080p. The unit also supports 480p and 480i output if your television is not HD-compatible.


These TVs are perhaps more similar than they first appear. The Samsung PN51F4500 plasma is the cheapest of its kind: a bare-bones, 1,024x768-pixel "720p" entry-level model. The Seiki SE50UY04 LCD is also one of the cheapest of its kind: a bare-bones, 3,840x2,160-pixel "4K" entry-level model. LCDs are typically more expensive than like-size plasmas, and 4K TVs even more so.


Strengths and weaknessesInitially, I tried out some 1080i content from AT&T U-verse. I suppose I could have started with DVD, but who cares about DVD I sat at roughly 9 feet from both TVs.


I've written multiple articles about this, as have many others, but the fact is, your eye has finite resolution. From a certain distance, your eye can't resolve the difference between 1080p and Ultra HD. With TVs this "small," your eye can't even tell the difference between 720p and 1080p, never mind 4K. So all the extra pixels on the Seiki are wasted. If you're curious if you'll be able to see the difference from where you sit, with your eyes, and whatever TV size you want to get, check out Chris Heinonen's excellent 4K Calculator.


Why was I sitting at 9 feet Studies have shown that most people sit between 9 and 10 feet from their TV (called the Lechner distance). If you sit closer, good on ya, but you're on one of the slopes of the bell curve. Personally, I usually sit 8 feet away from a 102-inch screen, so I'm way on the flat tail of the curve. At 9 feet, 50 inches is way too small to need more than 720p resolution. At that distance, 4K has dubious merit even on a 60-inch TV.


With up to 40 multi rate 3G-SDI input connections, depending on the model, the ATEM Constellation HD is compatible with all types of HD video sources. You can connect equipment in all HD television standards including 720p, 1080i and 1080p formats. Only multi rate 3G-SDI allows switching between HD formats so you can instantly adapt to the needs of the job you are doing anywhere in the world! The SDI inputs will also handle embedded audio and mix audio from all video inputs. Plus the program outputs include talkback, tally and camera control information. That means you can connect any of the switcher SDI outputs back to the camera for program return, camera control, and talkback. 1e1e36bf2d
