Methods, systems and computer program products for expressing classes of adaptation and classes of content in media transcoding

摘要

A generic method and means for defining and identifying classes of adaptation and classes of content in transcoding processes. The generic nature of the method and means allow for description of large quantity of adaptation and content classes, which would accommodate MMS, as well as other network applications. In addition, the method and means provide for a network application to communicate the defined classes of adaptation to a transcoding routine along with an indication as to whether adaptation of media content falling into such classifications are permitted or denied. The method and means also provide for the transcoding routine to communicate to the network application information about the adaptation performed in relation to the classification. The invention also provides for classification of the content of media elements both prior to and post adaptation.
