Abstract

As the Web client devices become more and more heterogeneous, the Web content providers should cater for multi-presentation services. Transcoding is seen as an alternative to deliver such services. When deployed offline, transcoding is space-consuming, inflexible, and difficult to maintain. On-demand transcoding, on the other hand, is CPU-consuming and time-delaying. Inspired by new multimedia standards - like JPEG 2000 and MPEG-4 -, a new adaptation called modulation is devised. Unlike transcoding, modulation does not involve complex computations and can offer high data reuse, which is beneficial to Internet data access. The specifications of modulation are presented, and so is its comparison with transcoding
