“…The fit.mpg movie was coded using the following sequence IBBPBBPBBPBBPBB. Since Vic does not support MPEG format, we used the Berkeley Mpeg_play tool to collect traces [Rowe and Smith, 1992]. Mpeg_play doesn't support network communication and hence the display cycle time was not affected by packet arrival.…”

This paper examines problems associated with display of live continuous media. Under the assumption that the network cannot guarantee the required bounds on delay and jitter and the operating system scheduling is non-realtime, there is a need to accommodate the delay and jitter in the end systems in order to maintain a desirable Quality of Service (QoS). We propose a method of video playback which requires accurate estimation of display cycle time of video frames and the delay suffered by frames in the packet network. We apply various deterministic forecasting methods used in time series analysis on experimental data collected from video transmission. Suitable methods are recommended for display cycle time and delay estimation.

“…Video on demand systems allow a user to select a video clip (perhaps a long clip, like a movie) and have the video, audio, and perhaps supporting documents, be instantly available for viewing [Rangan et al, 1992;Rowe and Smith, 1992]. The data usually can be played back at various speeds and with random access.…”

This paper presents a confederation of tools, called Coral, that combine to support the real-time capture of and subsequent access to informal collaborative activities. The tools provide the means to initiate digital multimedia recordings, a variety of methods to index those recordings, and ways to retrieve the indexed material in other settings. The current system emerged from a convergence of the WhereWereWe multimedia work, the Tivoli LiveBoard application, and the Inter-Language Unification distributed-object programming infrastructure. We are working with a specific user community and application domain, which has helped us shape a particular, demonstrably useful, configuration of tools and to get extensive real-world experience with them. This domain involves frequent discussion and decision-making meetings and later access of the captured records of those meetings to produce accurate documentation. Several aspects of Coral--the application tools, the architecture of the confederation, and the multimedia infrastructure--are described.

--Video distribution over the Internet poses many challenges. Due to the best-effort nature of today's public data networks, end system applications cannot rely on either bandwidth or delay guarantees. We designed and implemented a prototype of a multicast video distribution architecture involving knowledgeable active routers, a scalable video codec based on wavelet transformation, and a high-performance video scaling algorithm implemented as a router plugin. The plugin scales the video with an average overhead of only 22 µs per video datagram and is installed on-the-fly on the routers after the sender starts transmitting video for the first time. Through experiments on our test network, we show that we can dramatically improve the video quality on the receivers (up to 15 dB PSNR) by scaling the video on the routers to almost any target bandwidth. The target bandwidth is evaluated by the router solely based on monitoring of the load situation of the router's downstream links and can be adjusted within 50 ms.
