Serial Digital Interface (SDI) has, until recently, been the preferred transport mechanism for broadcast transmission. Its main advantage is that it provides a consistent and predictable delivery of data which is ideal for audio/video transport. However, networks in the broadcast industry are now in a state of flux. Increasingly there is a shift away from single-purpose legacy systems like SDI, and a shift towards multi-purpose IP-based networks.
PHABRIX Whitepaper: Using Pseudo-Random Binary Sequences to Stress Test Serial Digital Interfaces
In this whitepaper, PHABRIX discusses the use of pseudo-random binary sequences (PRBS – also referred to as pseudo-random bit sequences), along with bit-error rate tests (BERT – also referred to as bit-error ratio tests) to stress test serial digital interfaces. The purpose of any physical layer serial digital interface (PHY) is to transmit or receive data whilst preserving that data’s integrity. In practical systems the major cause of bit-errors is random noise. To stress test such systems, it is necessary to both generate a “noisy” bit stream and then analyze the output from the interface to determine the bit-error rate which represents the integrity of the data.
How Redundant Paths Work Using SMPTE ST 2022-7 for SMPTE ST 2110 Streams
SDI redundant paths required a frame sync to switch in to aid with a seamless switch over to a redundant feed. Not so with IP. The SMPTE ST 2022-7 is the standard for seamless protection which is packet-based, so no frame sync is required. Merrick Ackermans (Principal Engineer, MVA Broadcast Consulting) explains how this works with SMPTE ST 2110 streams.

Deep dive into SMPTE ST 2110-40 Ancillary Data
This presentation from Leigh Whitcomb (Architect, Imagine Communications) is a deep dive into the SMPTE ST 2110-40 Ancillary Data standard. The ANC standard for SMPTE ST 2110 is made up of two parts, one from the IETF and one from SMPTE. This presentation covers how SDI ANC services are transported by SMPTE ST 2110. New flexibility enabled by the standard will also be covered.

Creative collaboration: how working with DELTACAST enables customers to focus on their core business
Olivier Antoine (Head of Software Product Development, DELTACAST) “As a broadcast equipment designer and manufacturer, why should I rely on an external partner to implement my video interfacing?” This question arose at many solution providers before they became DELTACAST partners and started using our video interface solutions. These companies chose to entrust DELTACAST with the responsibility of implementing the video inputs and outputs of their products and appliances. Let’s have a look at why and how it works for them. With DELTACAST customers being professional –often large and renowned – broadcast equipment manufacturers, they generally have all the necessary knowledge and resources to design their video interfaces in-house, so the reason for relying on DELTACAST is rarely a question of lack of technical capability. So why have they chosen DELTACAST solutions instead? The reasons are several, but all come back to concentrating on what they are good at and relying on a collaborative, expert partner to deliver a key element of the solution quickly and efficiently. ‘Time-to-market’ is the first, most obvious reason, and common to all. Designing and prototyping, then integrating and producing, your own custom electronic devices takes a lot of time, while your need is generally linked...

BaM™ Product Highlight: MuxLab
MuxLab’s new 3G-SDI/ST2110 over IP Uncompressed Extender (model 500767) provides two methods of signal extension: one riding on an IP-infrastructure running 4K AV through a 10GB Ethernet switch; and another allowing a more traditional point-to-point extension using CAT5/6 or fiber cable. In both scenarios, uncompressed resolutions up to 4K/30 are supported.
Video Clarity at SMPTE 2016

Leader LV5490 Checks the UHD Detail in NEP Visions Production from London’s West End
London, United Kingdom, June 1, 2016: NEP Visions, one of the world’s most distinguished outside broadcast service providers, chose a Leader LV5940 4K multi-format waveform monitor as the master reference instrument during the recent UHD capture of Martin McDonagh’s play, Hangman. Performed at the Wyndham Theatre in London’s West End, the production has received very positive reviews including an accolade from The Telegraph as ‘the best new play of the year’. “The LV5940 proved very useful both for initial lineup and during the stage production,” says Chris Cannon, Head of Vision & VT at NEP Visions. “It enabled us to ensure precise phase alignment between the four HD-SDI channels that carry the UHD signal stream. We also used the LV5490 to check the colorimetry of the six Sony PMW-F55 cameras we used for for the project. It performed very well and has the further advantage of being extremely compact.” The resultant 173 minute production, starring David Morrissey, Andy Nyman and Johnny Flynn, has been delivered to Vue Cinema audiences around the UK as a 4K Digital Cinema Package. It was created by National Theatre Live in partnership with the Royal Court and Playful Productions. “Leader was the first manufacturer to...
