BS8K
NHK BS8K is a satellite television broadcasting service offered by NHK. Launched on 1 December 2018, it is the world's first television channel to broadcast in 8K resolution. Background NHK Science & Technology Research Laboratories had started to develop an 8K broadcast resolution in 1995. The format was first publicly displayed at the Expo 2005 in Aichi Prefecture, Japan, whereas the first 8K live feed broadcast were tested at the 2012 Summer Olympics in London. Due to the successful tests, plans for a television channel dedicated to airing an 8K resolution were approved by the NHK. On 1 August 2016, NHK started to test an Ultra HD channel on BS17, to prevent terrestrial digital broadcasting on its other networks. It featured a variety of 4K and 8K resolution programming, before concluding on 23 July 2018, after which an 8K network was assigned to a newly created BS 14 channel.

4320p
8K resolution refers to an image or display resolution with a width of approximately 8,000 pixels. 8K UHD () is the highest resolution defined in the Rec. 2020 ( UHDTV) standard. 8K display resolution is the successor to 4K resolution. TV manufacturers pushed to make 4K a new standard by 2017. At CES 2012, the first prototype 8K TVs were unveiled by Japanese electronics corporation Sharp. The feasibility of a fast transition to this new standard is questionable in view of the absence of broadcasting resources. In 2018, Strategy Analytics predicted that 8K-ready devices will still only account for 3% of UHD TVs by 2023 with global sales of 11 million units a year. However, TV manufacturers remain optimistic as the 4K market grew much faster than expected, with actual sales exceeding projections nearly six-fold in 2016. In 2013, a transmission network's capability to carry HDTV resolution was limited by internet speeds and relied on satellite broadcast to transmit the high ...

Progressive Scan
Progressive scanning (alternatively referred to as noninterlaced scanning) is a format of displaying, storing, or transmitting moving images in which all the lines of each frame are drawn in sequence. This is in contrast to interlaced video used in traditional analog television systems where only the odd lines, then the even lines of each frame (each image called a video field) are drawn alternately, so that only half the number of actual image frames are used to produce video. The system was originally known as "sequential scanning" when it was used in the Baird 240 line television transmissions from Alexandra Palace, United Kingdom in 1936. It was also used in Baird's experimental transmissions using 30 lines in the 1920s.Burns, R.W. ''John Logie Baird, Television Pioneer'', Herts: The Institution of Electrical Engineers, 2000. 316. Progressive scanning became universally used in computer screens beginning in the early 21st century. Interline twitter This rough animatio ...

1080i
In high-definition television (HDTV) and video display technology, 1080i is a video display format with 1080 lines of vertical resolution and Interlaced video, interlaced scanning method. This format was once a standard in HDTV. It was particularly used for broadcast television because it can deliver high-resolution images without needing excessive bandwidth. This format is used in the SMPTE 292M standard. Definition The number "1080" in 1080i refers to the number of horizontal lines that make up the vertical resolution of the display. Each of these lines contributes to the overall detail and clarity of the image. The letter "i" stands for Interlaced video, interlaced. This is a technique where the image is not displayed all at once. Instead, the frame is split into two fields. One field contains the odd-numbered lines, and the other field contains the even-numbered lines. These fields are displayed in rapid succession, giving the appearance of a full image to the human eye. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
HDTV
High-definition television (HDTV) describes a television or video system which provides a substantially higher image resolution than the previous generation of technologies. The term has been used since at least 1933; in more recent times, it refers to the generation following standard-definition television (SDTV). It is the standard video format used in most broadcasts: Terrestrial television, terrestrial broadcast television, cable television, satellite television. Formats HDTV may be transmitted in various formats: * 720p (): 921,600 pixels * 1080i () interlaced scan: 1,036,800 pixels (≈1.04Mpx). * 1080p () progressive scan: 2,073,600 pixels (≈2.07Mpx). ** Some countries also use a non-standard CTA resolution, such as : 777,600 pixels (≈0.78Mpx) per field or 1,555,200 pixels (≈1.56Mpx) per frame When transmitted at two megapixels per frame, HDTV provides about five times as many pixels as SD (standard-definition television).
