This paper specifically targets a system to improve the trade-off between the storage bit-cost of the different representations, the transcoding complexity and transmission efficiency (i.e. bitrate-quality trade-off at transmission) of the requested representation by the end-client while guaranteeing that the delivered output bitstream remains compliant with the legacy decoding system available at the client.
This paper addresses the problem of multi-profile encoding and delivery system optimization for the purpose of standard HTTP-based Adaptive Bitrate (ABR) video streaming. Such delivery systems must process, encode, and usually store the same content in different (bitrate, resolution) pairs, which defines a set of encoding profiles or coded representations (a.k.a. bitrate ladder), to serve and adapt the video content to various end user bandwidth requirements and device capabilities.
The presented research work specifically targets such a system to improve the trade-off between the storage bit-cost of the different representations, the transcoding complexity and transmission efficiency (i.e. bitrate-quality trade-off at transmission) of the requested representation by the end-client while guaranteeing that the delivered output bitstream remains compliant with the legacy decoding system available at the client.
For that purpose, we propose...
