Abstract :
Unequal error protection (UEP), which provides important data with more protection, has been proven to be able to produce better quality in image communication. Previous UEP schemes are mostly proposed for single-image or single-program scenarios. Yet few are developed for multiple programs. Inspired by the MPEG-2 transport stream (TS), in this paper we transform the conventional TS packets to be length-variable, and propose a new UEP scheme, which is suitable for multiple-program scenarios. A theoretical model for this scheme is built in this paper, and experimental results also demonstrate the effectiveness of the scheme.
