DeckLink IP features 3 channels of capture and playback to 2110 IP broadcast systems via an SFP based optical fiber Ethernet connection. It supports all 720p, 1080i and 1080p standards up to 1080p60.
For connection to both 3G-SDI and 2110 IP systems, this model has 2 capture and playback channels to 2110 IP via RJ45 Ethernet, 3G-SDI and ref out. Supports 720p, 1080i and 1080p standards to 1080p60.
DeckLink IP connections are multi rate so they support all SD and HD formats. Plus the DeckLink IP/SDI HD model includes both 2110 IP and 3G-SDI on the same card, so it can connect to all your existing SDI broadcast equipment, while simultaneously connecting to new IP based infrastructure. Or you can just use the 3G-SDI output for local monitoring! In standard definition, DeckLink IP supports both 525i59.94 and 625i50 standards. In high definition, DeckLink IP cards support all 720p video standards up to 720p60, all 1080 interlaced standards up to 1080i60 and all 1080p standards up to 1080p60. Plus there is no complex change over as the cards can switch instantly to a new video standard.
Each 3G-SDI video input features its own dedicated standards converter. That means ATEM SDI will automatically convert 1080p, 1080i and 720p sources to the switcher video standard! By default the switcher will set its video format automatically, however you can also set the switcher to any video standard manually! The SDI outputs are a true "aux" outputs so you can independently customize the source video routed to each SDI output. All outputs can be connected to cameras as they include camera control and tally information. On the more powerful ATEM SDI Pro and ATEM SDI Extreme models, the SDI output can also be selected to display the built in multiview.
Initially the existing 5:3 aspect ratio had been the main candidate but, due to the influence of widescreen cinema, the aspect ratio 16:9 (1.78) eventually emerged as being a reasonable compromise between 5:3 (1.67) and the common 1.85 widescreen cinema format. An aspect ratio of 16:9 was duly agreed upon at the first meeting of the IWP11/6 working party at the BBC's Research and Development establishment in Kingswood Warren. The resulting ITU-R Recommendation ITU-R BT.709-2 ("Rec. 709") includes the 16:9 aspect ratio, a specified colorimetry, and the scan modes 1080i (1,080 actively interlaced lines of resolution) and 1080p (1,080 progressively scanned lines). The British Freeview HD trials used MBAFF, which contains both progressive and interlaced content in the same encoding.[citation needed]
It also includes the alternative 14401152 HDMAC scan format. (According to some reports, a mooted 750-line (720p) format (720 progressively scanned lines) was viewed by some at the ITU as an enhanced television format rather than a true HDTV format,[35] and so was not included, although 19201080i and 1280720p systems for a range of frame and field rates were defined by several US SMPTE standards.)[citation needed]
These first European HDTV broadcasts used the 1080i format with MPEG-2 compression on a DVB-S signal from SES's Astra 1H satellite. Euro1080 transmissions later changed to MPEG-4/AVC compression on a DVB-S2 signal in line with subsequent broadcast channels in Europe.[citation needed]
The Freeview HD service currently contains 13 HD channels (as of April 2016[update]) and was rolled out region by region across the UK in accordance with the digital switchover process, finally being completed in October 2012. However, Freeview HD is not the first HDTV service over digital terrestrial television in Europe; Italy's RAI started broadcasting in 1080i on April 24, 2008, using the DVB-T transmission standard.[citation needed]
If all three parameters are used, they are specified in the following form: [frame size][scanning system][frame or field rate] or [frame size]/[frame or field rate][scanning system].[50] Often, frame size or frame rate can be dropped if its value is implied from context. In this case, the remaining numeric parameter is specified first, followed by the scanning system.[citation needed]
For example, 19201080p25 identifies progressive scanning format with 25 frames per second, each frame being 1,920 pixels wide and 1,080 pixels high. The 1080i25 or 1080i50 notation identifies interlaced scanning format with 25 frames (50 fields) per second, each frame being 1,920 pixels wide and 1,080 pixels high. The 1080i30 or 1080i60 notation identifies interlaced scanning format with 30 frames (60 fields) per second, each frame being 1,920 pixels wide and 1,080 pixels high. The 720p60 notation identifies progressive scanning format with 60 frames per second, each frame being 720 pixels high; 1,280 pixels horizontally are implied.[citation needed]
Systems using 50 Hz support three scanning rates: 50i, 25p and 50p, while 60 Hz systems support a much wider set of frame rates: 59.94i, 60i, 23.976p, 24p, 29.97p, 30p, 59.94p and 60p. In the days of standard-definition television, the fractional rates were often rounded up to whole numbers, e.g. 23.976p was often called 24p, or 59.94i was often called 60i. Sixty Hertz high definition television supports both fractional and slightly different integer rates, therefore strict usage of notation is required to avoid ambiguity. Nevertheless, 29.97p/59.94i is almost universally called 60i, likewise 23.976p is called 24p.[citation needed]
For the commercial naming of a product, the frame rate is often dropped and is implied from context (e.g., a 1080i television set). A frame rate can also be specified without a resolution. For example, 24p means 24 progressive scan frames per second, and 50i means 25 interlaced frames per second.[51]
Standard 35mm photographic film used for cinema projection has a much higher image resolution than HDTV systems, and is exposed and projected at a rate of 24 frames per second (frame/s). To be shown on standard television, in PAL-system countries, cinema film is scanned at the TV rate of 25 frame/s, causing a speedup of 4.1 percent, which is generally considered acceptable. In NTSC-system countries, the TV scan rate of 30 frame/s would cause a perceptible speedup if the same were attempted, and the necessary correction is performed by a technique called 3:2 pulldown: Over each successive pair of film frames, one is held for three video fields (1/20 of a second) and the next is held for two video fields (1/30 of a second), giving a total time for the two frames of 1/12 of a second and thus achieving the correct average film frame rate.
Non-cinematic HDTV video recordings intended for broadcast are typically recorded either in 720p or 1080i format as determined by the broadcaster. 720p is commonly used for Internet distribution of high-definition video, because most computer monitors operate in progressive-scan mode. 720p also imposes less strenuous storage and decoding requirements compared to both 1080i and 1080p. 1080p/24, 1080i/30, 1080i/25, and 720p/30 is most often used on Blu-ray Disc.
Glans:So Avid is changing the codec naming from the usual DNxHD 36, 120, 185 and 185x (25p) to DNxHD LB, SQ, HQ and HQx. Not really. The latter three are called DNxHR, not DNxHD. They are in essence the same compression type, yes, but DNxHD is still the HD flavor, DNxHR (not D but R) can be most any canvas size and framerate.
The GTX 1080 Ti acquits itself well in the first benchmark we're looking at, Ubisoft's Assassins Creed Odyssey. The large and detailed open world of this game makes it challenging to render, and we can see that with the 1440p results here: only the GTX 1080 Ti and RTX 2080 manage to sustain 60fps or higher on average. The RTX 2070 is nine per cent behind the GTX 1080 Ti here, while the RTX 2080 is three per cent ahead of the flagship Pascal card. At 4K, we see the GTX 1080 Ti again take second place with a playable 31fps, although we'd definitely recommend the use of G-Sync to smooth out any scene-to-scene frame time variation.
Far Cry 5, released in 2018, is our first of three new benchmarks to debut alongside our RTX 2080 and 2080 Ti reviews, so we've included it in this new iteration of our GTX 1080 Ti benchmarks as well. The 1080 Ti slips a little behind the RTX 2080 in this newer title, although the difference is only three frames per second at 4K. Meanwhile, the GTX 1080 is a substantial distance behind, 22 per cent at 4K.
Rise of the Tomb Raider comes with an interesting three-party benchmark, although it's not quite as demanding as the game itself. The GTX 1080 Ti outperforms the newer and more expensive RTX 2080 here at 4K, although the difference is just a couple of frames per second. Expect a 20 per cent gap to the RTX 2080 Ti, though it's not shown here.
Make sure you're gaming system is not set to 1080p. The HD PVR does not understand this format. Please set the output resolution to 1080i or 720p. Please see the appropriate setup instructions for your game console:

As you are likely aware by now Foo Fighters were the final performers at the closing ceremony of the Invictus Games which took place this past Sunday, September 14th, in London, United Kingdom. The band played for a little over an hour but in their highlights of the evening BBC broadcast only three full songs on Television, as well as part of a fourth. It seemed likely that we would have to make do with this short snippet of the performance but thanks to an anonymous upload to Usenet servers a complete version is now available.
