Signal Management Processing & QC
Broadcasting has always relied on initials and acronyms to bypass the otherwise unwieldy technical or jargon-heavy terms and expressions that pop up in everyday usage for TV types. Among the longest established is T&M, standing for test and measurement. In the last 20 or so years it has been joined by QC (or QA) for Quality Control (Quality Assurance). QA is the operational procedure that relies on T&M gear to check programme material complies with broadcast distribution and transmission standards. Even today traditional – or baseband – T&M gear is often thought of as a box with a meter or graphical display that is used by an engineer in a workshop, master control room or racks area. With a Development and Channel Manager for Europe, the Middle East and Africa (EMEA) at Wohler, says hardware and software in this sector are both necessary but each has applications and places in the production chain. “T&M has a clear purpose and place of importance in guaranteeing quality of service and quality of experience for consumers,” he comments. “In the same way that multiple delivery platforms are proliferating, we expect continued demand for multiple methodologies – both hardware and software – to ensure that content and the equipment utilised to prepare that content, whether real-time using hardware or file-based using software, meets established standards and practices.” What is changing, Allford adds, is the long-held image of T&M of a stand-alone process that happens away from other parts of postproduction and distribution. “Market expectation is shifting to wanting integration of T&M capabilities as part of mainstream A/V monitoring devices,” he observes. “Also, T&M needs to provide capability to include diagnostics for MPEG transport streams as part of the

Vital QC
The European Broadcasting Union (EBU) Strategic Programme on QC has identified four main application areas for this process: ingest, legacy archive transfer to files, final programme delivery and programme exchange. The EBU Quality Control Workshop in Geneva discussed why QC is important, how to perform QC on media files and their content, end-to-end QC integration, the top 20 QC checks to make and the future of automated QC – what can we expect to come? In the run up to the conference it emerged that a number of European broadcasters, including the BBC, would like to see QC carried out at post-production facilities. In the UK the Digital Production Partnership (DPP) is looking at this way of working becoming part of its standards for the production and distribution of programmes. Formed by the BBC, ITV and Channel 4, the

The two are inextricably linked but they are not the same. T&M covers the engineering process for analysing the performance of equipment, ensuring it is running within expected parameters and all components are connecting and functioning properly. QC/
