Optimizing Scalable Video Compression for Efficient Implementation on a VLIW Media Processor

“…This results in a scalable compression scheme with a very competitive complexity-performance tradeoff. In particular, the algorithm achieves the performance of the baseline JPEG scheme at much lower complexity, while adding the scalability feature [3], [7].…”

“…The proposed video compression algorithm [3], [6], [7] produces a Fine-Granular Scalable (FGS) stream, which is often called an embedded bit-stream. An FGS bit-stream contains all lower bit rates embedded at the beginning of the stream; thus the bits are ordered from the most important to the least important.…”

“…In this paper, principles of algorithm-architecture co-design are studied using as a reference an implementation of a scalable video compression algorithm [3] on a VLIW media processor [1]. The algorithm-architecture co-design and the low-cost video coding algorithm are explained in Section II and Section III respectively.…”

“…Besides acoustic and linguistic features used in speech summarization, prosody is also the particular information and can be used to improve the summarization performance. In [3], prosodic features such as pitch, power, and pause are applied to analyze the summary units and their dependency relations. This study focuses on speech-to-speech sentence compression of TV news broadcasts.…”
