WHAT IS SDI? SDI = Serial Digital Interface. In 1989, The Society of Motion Picture and Television Engineers ( SMPTE ) announced a new digital video format for the broadcast industry, used for mostly uncompressed content in TV studios and production facilities. The first format was simply called SDI, and could carry enough info for[…]
High Dynamic Range AV DESIGN INFRASTRUCTURE When AV designers specify systems, the infrastructure (how the system is transmitted, switched and displayed) is one of the first decisions made. Large systems and large displays make it more likely the central backbone will need to be much more robust in scale and scalability. If the need is[…]
Valens updated HDbaseT by announcing the Colligo HDBaseT family of chips at ISE recently. They now support native USB 2.0, HD audio, transmission of 4K video over Cat-5/6 cables up to 100m in length, and add single- and multi-mode fiber transport over distances up to 10km. Not a bad spot to ask whether HDbaseT is becoming a[…]
In March 2011, the IEEE 1733 standard was approved for publication. It specified how to transport Layer 3-encapsulated AV data. The awesome Layer 2 Quality of Service (QoS) provided by the IEEE 802.1 AVB standards is one of the best things to come with this standard. Also big: the standard is reliable, well known, what[…]
Some basic facts about the AVB standard: NOT proprietary: Good news, open standard, everyone understands. Manufacturers, like Pakedge will make products that support the standard, and will back their products up with their usual strong after sale support directly. Same will go for others who produce AVB capable equipment. NOT a whole lotta V: AVnu[…]
So how does AVB work? Timing is everything in AV. . In your office or conference room, you have become accustomed to video and audio that behave in a certain way. You will not, for example, put up with video that takes 10 seconds to begin playing, nor would you accept video if it’s audio was delayed even a[…]
What is it? In an ideal world, all video and audio would just hop onto the nearest network, to be pulled accessed anywhere that network goes, bandwidth permitting. With network bandwidth increasing by the day, why not? Because IEEE 802.1 standards are needed to make this happen. See, data networks typically give you the data when they can,[…]
Crazy flexible new system, check it out: The new CAT-Linx cards, which easily install in any available slot of the Linx Prime switcher chassis, with DVI/HDMI and fiber cards. Using Power over HDBaseT (PoH) technology, CAT-Linx I/O cards provide 48 VDC of power directly to endpoints through the same cable that carries signals, (no external[…]
