content in a broad variety of formats, and in numerous “profiles” — sets of specific parameters — within those formats. The automation of transcod- ing processes has helped to reduce the time and cost involved in handling these tasks, but it has become clear that a more sophisticated approach to managing file-based media and the processing applied to that media can yield significant operational and business benefits. The concept of “media transformation” responds to this need, building on the value pro- vided by transcoding to enable more efficient and streamlined processing of file-based media across the entire workflow. Ultimately, this approach supports an optimized media pipeline that maximizes the quality of both me- dia assets and the operation’s outputs. Rather than simply convert files from one format to another, media trans- formation solutions extract, index and leverage intelligence about media files in order to automate key media management and processing steps required to hit the target output parameters. What’s more, with such a solution, the content creator or pro- vider can simply, quickly, and afforda- bly ensure that as media is ingested, transcoded, edited, and otherwise transformed for distribution, the quality and value of that content is main- tained, or even enhanced. For exam- ple, the solution might adjust (normal- ize) the audio structure to assure that it meets technical and/or regulatory requirements; adjust video to make sure that it meets broadcast gamut colour requirements; and ensure that closed caption data is properly dis- played for the target distribution outlet and end-user device. Within a typical media transformation workflow, content is stored within a single system or repository. A pool of central processing unit (CPU)/graph- ics processing unit (GPU) resources provides the processing power for transformational algorithms incorporat- ed into the media transformation plat- form. The processes effectively run on a single system built on commodity IT resources rather than on more expen- sive — to buy and to maintain — dis- crete dedicated processing systems. Though transcoding plays a central role in virtually every media facility today, media transformation sup- ports a more holistic — and ultimately more cost-effective — approach to audio and video processing. With this approach to managing file-based assets, content creators and providers can prepare and deliver media with a much greater degree of efficiency and accuracy, both critical capabilities in today’s competitive multiplatform media marketplace.
