This paper presents a new scheme for TFRC-based rate control with JPEG 2000 real-time video streaming over the Internet. Due to the low-delay and error resilient nature of JPEG 2000, JPEG 2000 real-time video streaming is a viable streaming solution on the Internet. In this paper, we have implemented a system using JPEG 2000 real-time video streaming with a TFRCbased algorithm; we modified it to add a function of prediction of possible packet loss by the ratio of long-term RTT to short-term RTT. We have evaluated a scheme simply adapted from TFRC (Simple Adaptation Method) and our proposal (Loss Prediction Method) based on the number of dropped bytes, received video quality and total TCP throughput. Our experimental result shows Loss Prediction Method has better performance on JPEG 2000 real-time video streaming.
We consider the problem of distributing video data from a server to a population of interested clients. Deploying overlay network with application-layer multicast, we propose a FEC-based scalable multiple description coding (SMDC) scheme to arrive at the solution to the problem. Without the performance penalty on each receiver, our SMDC can achieve optimal performance of each client with different network conditions as simply as additional assembling and truncating operations. In the mean time, a R-D allocation algorithm is presented to decide the rates of the source and channel. Simulation shows that our SMDC have better quality for heterogeneous receivers than traditional scheme.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
