A protocol for adaptation-aware multimedia streaming
2003
2003 International Conference on Multimedia and Expo. ICME '03. Proceedings (Cat. No.03TH8698)
Preserved Fulltext
Multimedia streaming is becoming ever more popular. However, the Internet does not support streaming with its high bandwidth and low latency requirements very well. ...
Unfortunately, none of the known protocols can meet all requirements. ...
Stream multiplexing and hence the delivery of scaling guidelines using a separate stream is supported by [8] . ...

This paper proposes a multiplexing scheme for improving the bandwidth efficiency of existing VoIP applications. ...
Existing voice-over-IP (VoIP) applications transmit voice data in packets of very small size to minimize packetization delay, causing very inefficient use of network bandwidth. ...
It is now being used by various network applications, including H.323, for delivery of media stream. ...

In this paper we propose a novel end-to-end architecture for H.264 unicast video streaming over the Internet. ...
We show that the network-friendly specification of H.264, and the novel technical characteristics of SCTP, when coupled together are able to provide a highly adaptive and flexible system for unicast video ...
These streams could either be multiple media streams encapsulated in RTP packets (figure 2). ...

Finally, based on all such considerations, we offer sketches of several possible hybrid architectures, with different degrees of offloading of processing in cloud, that are likely to emerge in the future ...
To bridge the gaps, we suggest specific improvements in cloud ingest, signal processing, and transcoding stacks. Cloud playout is also identified as critically needed technology for convergence. ...
To route streams to cloud, broadcast workflow produces contribution streams, one for each channel, and then sends them over IP (e.g., using RTP+FEC or SRT) to cloud. ...

This paper provides guidelines for best practices of VoLTE deployment as well as practical performance evaluation based on field measurement data from commercial LTE networks. ...
During the phases of VoLTE deployments, carriers would typically face challenges in understanding the factors affecting the VoLTE performance and then optimizing it to meet or exceed the performance of ...
Another technique is to use the 2x2 MIMO codewords (or higher order MIMO) for splitting the VoLTE and PS data into two different streams with Rank-2 spatial multiplexing, i.e. segmentation of packets at ...
