The DPP issued a statement “All digital does is carry the saying it “hopes to achieve content. If the video is illegal and industry-wide collaboration with doesn’t meet technical standards broadcasters and QC tool vendors, or the audio is too loud or too soft industry-wide standards for QC or down on one leg, that is going to cause problems either during reporting, tests and terminology and best practice sharing among post or on transmission, so it has broadcasters.

The EBU QC conference included who understands the nuances of the subject and what to look for. Robert Millis, Product Manager for Compressed Servers and File QC Systems at Harris Broadcast Communications, is of the opinion that traditional T&M is “still critical to overall success”. He explains that material in file-form typically starts life as real-time feeds or ones that have been creatively modified. “Encoding/compression technology, while highly evolved for most formats, is not a lossless process,” says Millis. “Another risk point is file-based media has gone through workflows that may affect the captioning or other ancillary data that is part of the complete package for broadcast delivery. Baseband T&M products have a role to monitor during ingest, serve as a double check during the edit process and at broadcast playout. Traditional T&M products, driven by experienced operators, can also differentiate between intended artistic effects and objectionable artefacts, filtering out false positives that can be hard to avoid in the automated tool sets.”

Sound Results
The blurring of the lines between professional broadcast and streamed distribution platforms has opened up a new area of research and development for some wellestablished T&M manufacturers. Danish company Brüel & Kjær is noted for its academic approach to ensuring good sound quality in broadcasting and live sound. Its specialised equipment is being used by manufacturers of handheld units, such as smartphones and tablets, because people are listening on headphones or earphones and expect good quality audio. “It’s opened up a whole new T&M market,” comments Julian Simpson, Production QA Programme Manager of Brüel & Kjær Sound and Vibration Measurement. “We’re using our core technologies, such as high quality measuring microphones and the dummy head and torso simulation set-up, to test these systems. As well as products like tablets and

File QC
T&M manufacturers are now being joined by specialised software developers producing systems for QC. Companies like Amberfin do not claim to produce T&M equipment but develop programs using test and measurement principles to perform checks on file-based material during the transmission process. “There’s still the need to measure signals upstream, in post-production and production, and that’s done using traditional machines,” comments Bruce Devlin, Chief Technology Officer of Amberfin. “When you get more into transmission you still need the same measurements but in a different way. This is because, although there are now more channels available, many have fewer viewers, so there is less money to be spent on running them, which means more automation is being used to produce good results.” Devlin explains that this situation means broadcasters are using software variants of hardware equipment downstream – in distribution/transmission – to maintain quality and assurance. “The way things should be working is to check material with a T&M box and then in software as it goes down the chain,” he observes. “But all measurements seem to get thrown away when something is put into video on demand. People have to consider the life cycle of something and find a way of remembering what they did upstream and then incorporate those changes into the version being streamed later.”
