A quick look at the lens to display pipeline highlights some trivial-seeming bottlenecks that place important constraints on motion imaging systems. One of these is the connection to the consumer display. The announcement of HDMI 2.1 is key to advancing to 4K and beyond, with additional support for HDR, and increased frame rates for UHD video.
Television remote controls used to be simple devices; channel up, down, volume up, down and power on, off. Today, a television remote control may have 50 or more functions. Yet, viewers seldom use more than a few of those capabilities because they do not understand what the buttons do. Better remote control design is the solution.
Migration towards ST 2110 and ST 2022-6 video networks for production and content delivery is picking up pace as the advantages of IP versus traditional SDI over coaxial cable carriage become more evident. The key drivers of IP include the introduction of more flexible and scalable business models based on virtualization and cloud technologies, along with the economies of scale and speed of technology development that stem from the use of commercial off-the-shelf (COTS) IT equipment.
Metadata is well known to hold the keys to good user experiences by making content readily searchable and enabling more compelling or relevant recommendations, but has been held back by limited depth and need for laborious manual production.
The Digital Video Broadcast (DVB) has added final revisions to its first DVB UHD-1 specifications for Ultra HD covering transport of UHD services over IP networks. This comes just over a year after the DVB Project approved the underlying standards in October 2016 as UHD-1 Phase 2 (TS 101 154) for broadcast networks.
4K imagery has become the quality standard for many broadcast applications. A key requirement is that the transmission links be of sufficient bandwidth. Links using H.264 can be overwhelmed by the much higher bandwidth requirements of 4K video. HEVC is often the better solution. How does it work and what are some benefits?
Last year, more than 400 original series hit the small screen. With no signs of slowing; predictions suggest 2017 could beat records, with over 500 programmes launched. It’s now possible for companies to make video easily accessible online and with the widespread adoption of Video on Demand (VOD) the content floodgates have opened like never before.
Japanese broadcasters are preparing for the 2020 Tokyo Olympic Games, including getting ready for 8K UHDTV. In 2018, public broadcaster NHK will roll out the needed ISDB-S3 standard. The multichannel R&S SLG signal generator from Rohde & Schwarz was used for the 8K satellite tests.
