This paper presents results from a study of stieaming h~EG compressed video over the pubHc Inteme& using the RTP and UDP tianspoti protocok. TmTofie minute video etips were h~EG coded at rates of 384 Kbps and 1 l~ps. The resultant coded streams were transmitted at their respective data ra$esbe~een four sites in the United States and Europa hIeasurements(More)
—This paper analyzes the distortion in decoded video caused by random packet losses in the underlying transmission network. A recursion model is derived that relates the average channel-induced distortion in successive P-frames. The model is applicable to all video encoders using the block-based motion-compensated prediction framework (including the(More)
This paper describes extensions to the High Efficiency Video Coding (HEVC) standard that are active areas of current development in the relevant international standardization committees. While the first version of HEVC is sufficient to cover a wide range of applications, needs for enhancing the standard in several ways have been identified, including work(More)
The JVT/H.264 video coding standard can achieve considerably higher coding efficiency than previous standards. Unfortunately this comes at a cost in considerably increased complexity at the encoder mainly due to motion estimation and mode decision. In this paper, we propose a new scheme to jointly optimize motion estimation and mode decision. Simulation(More)
—Packet video will become a significant portion of emerging and future wireless/Internet traffic. However, network congestion and wireless channel error yields tremendous packet loss and degraded video quality. In this paper, we propose a new complete user datagram protocol (CUDP), which utilizes channel error information obtained from the physical and link(More)
