The professional video business is built around a myriad of technologies. In the production arena, vast arrays of high-definition formats are used both for acquisition and post-production editing. Broadcasters use MPEG-based compression schemes for content delivery. Other services that may be offered include low bit-rate programme delivery to portable devices, internet media streaming, and home video-on-demand services.
The differing technical requirements of these media services mean a wide variety of image compression techniques are needed in order to meet the bandwidth limits of the chosen transmission path. Picture quality and A/V Delay assessment on the resulting video signal are essential to ensure that the best use is being made of the available bandwidth.
This white paper introduces these PQA facilities and explains how they can be used to assess picture quality across a range of possible set-ups.
