Adaptive format conversion information as enhancement data for scalable video coding
Scalable coding techniques can be used to efficiently provide multicast video service and involve transmitting a single independently coded base layer and one or more dependently coded enhancement layers. Clients can decode the base layer bitstream and none, some or all of the enhancement layer …

A spatial scalable video coding with selective data transmission using wavelet decomposition.
In this research a scalable video coding framework is proposed, mainly focusing on spatial scalability, and a subjective data compression algorithm based on: (1) quality, (2) resolution (target output device), and (3) bandwidth. This framework enables the scalable delivery of video based on the …

SoftCast : exposing a waveform interface to the wireless channel for scalable video broadcast
Video broadcast and mobile video challenge the conventional wireless design. In broadcast and mobile scenarios the bit-rate supported by the channel differs across receivers and varies quickly over time. The conventional design however forces the source to pick a single bit-rate and degrades …

Real-time data flow models and congestion management for wire and wireless IP networks
In video streaming, network congestion compromises the video throughput performance and impairs its perceptual quality and may interrupt the display. Congestion control may take the form of rate adjustment through mechanisms by attempt to minimize the probability of congestion by adjusting the rate …
