Slice-balancing H.264 video encoding for improved scalability of multicore decoding

摘要

With multicore architectures being introduced to the market, the research community is revisiting problems to evaluate them under the new preconditions set by those new systems. Algorithms need to be implemented with scalability in mind. One problem that is known to be computationally demanding is video decoding. In this paper, we will present a technique that increases the scalability of H.264 video decoding by modifying only the encoder stage. In embedded scenarios, increased scalability can also enable reduced clock speeds of the individual cores, thus lowering overall power consumption.
