Video Compression for Wireless Transmission: Reducing the Power Consumption of the WPAN Hi-Speed Systems

Optimization of high-definition video coding and hybrid fiber-wireless transmission in the 60 GHz band

“…However, there is a trade-off between the power needed to radiate larger bandwidth for uncompressed video and the power consumed for the computations of an encoder and a decoder for compressed video transmission. According to [4], low complexity compression can, in fact, bring about reduction in power consumption for a 60 GHz wireless video transmission system compared to the uncompressed case, while at the same time keeping delay under the acceptable limit.…”

Extending JPEG-LS for low-complexity scalable video coding

“…The main advantage of JPEG-LS is a possibility to set up the maximum error value per pixel by choosing a bound on the differences for near-lossless coding (so-called near parameter or lossy-factor). Another plus of JPEG-LS is an extremely low level of implementation complexity 8 and memory consumption at the encoder side. The encoding process requires less than two rows of samples only (less than 10KByte).…”
