Abstract:
1. A method of converting data items of a media content all pre-encoded in accordance with the H.264/Advanced Video Coding (AVC) protocol into encoded data items decodable by a decoder operating in accordance with a Scalable Video Coding (SVC) baseline profile defining two or more media layers, wherein the pre-encoded data items are stored in a media file in form of pre-encoded Network Abstraction layer (NAL) units and are compliant with the single-layer AVC high profile, the method comprising: reading the pre-encoded AVC NAL units from the media file; generating one or more dummy data items in form of one or more dummy NAL units to define a SVC scalable baseline profile Base Layer (BL); marking the read pre-encoded AVC NAL units as belonging to a SVC Enhancement Layer (EL) and manipulating the AVC NAL units being pre-coded by a predictive encoding type not supported by the SVC scalable baseline profile to be compliant with the SVC scalable baseline profile; and generating at least one bitstream comprising the marked encoded data items of the media content and the generated dummy data items.
