Abstract:
1. A method of delivery of encoded scalable media data having associated media content comprising: formatting original scalable encoded media data into a format including a first portion corresponding at least to non-media type specific scalability attributes of the original encoded media data wherein at least some non-media type specific scalability attributes have a universal meaning across a plurality of media types and said first portion corresponding to data structure information of a second portion and the second portion corresponding to the original scalable encoded media data arranged in a non-media type specific indexable data structure having at least one dimension wherein said encoded media data is arranged in format generic to all types of media; providing information corresponding to receiving attributes of a media destination of at least one type of scalable encoded media; generically transcoding the formatted media data prior to delivery to the media destination and without knowledge of the content of the original media data to generate a scaled version of the formatted media data adapted to the receiving attributes of the media destination, based on matching the scalability attributes and the receiving attributes, wherein the matching includes determining whether a scalability attribute identified in the first portion of the formatted media data matches a received attribute of the receiving attributes of the media destination; if the scalability attribute matches the received attribute, comparing a limit for the received attribute to a value for the scalability attribute; and the transcoding includes scaling the scalability attribute if the value is outside the limit.
