“…Storage and delivery of video data have been the topic of many recent research works and prototype implementations, but much of this research is directed towards the technology needed to build video on demand (VOD) servers for entertainment purposes [8,9]. However, we address the unique requirements of video storage and delivery in digital libraries since there are major differences between the VOD and digital library services, in terms of the characteristics of the video data and the viewing frequencies.…”

“…One of the most common video compression standards currently in use is called MPEG [11]. A typical 1-h video in MPEG compressed form requires about 1 to 2 gigabytes of disk storage [2,12] and must be delivered at the rate of 1.5 megabitsÂsecond to avoid``jerkiness'' [1,4,8,9]. Furthermore, in many cases a video object must be delivered synchronously with its associated sounds, thus complicating the storage and delivery problem [2,5].…”

“…The store-and-forward (SAF) is a well-known approach [22,23] in which the MPEG video data are "rst transported from server to central o$ce (CO) in bursts. Then the video data are bu!ered in CO before delivering to the playback destination in real-time.…”

SUMMARYThis paper focuses on the optimization of network bandwidth allocation and bu!er dimensioning to transport pre-stored MPEG video data from source to playback destination across ATM networks. This is one of the most important issues in the support of video-on-demand (VoD) service. This paper provides a novel scheme in the dynamic allocation of bandwidth to segments of video using ABR mode. The dynamic bandwidth allocation is based on a new concept, called playback tunnel which is obtained from the tra$c characteristics of the pre-stored MPEG video trace to determine the optimum of transmission bandwidth as well as the bu!er capacity to ensure that the playback bu!er neither under#ows nor over#ows. The proposed scheme is tested with real-life MPEG video traces. The obtained results have shown its signi"cant performance improvement in terms of the capacity of playback bu!er, the start-up playback delay, the size of video segment and the network multiplexing gain.

“…Design of video server to support many users has been studied by a number of authors [19], [20]. The buffering architecture and requirements for stored video on demand have been discussed in [21], [22]. The authors in [23] discussed the video-on-demand (VoD) server with unrestricted VCR function in multicast VoD system.…”

In recent years, there has been a strong interest in transmitting compressed video over packet switched networks, such as asynchronous transfer mode (ATM). Previous work has dealt with transmitting MPEG over constant bit rate (CBR) and variable bit rate (VBR) services of ATM. The available bit rate (ABR) service of ATM is expected to be much more cost effective than CBR or VBR. However, there hasn't been much work done on running interactive client/server applications (for example, video on demand) over ABR.In this paper, we have developed a framework to design interactive video systems transmitting MPEG video over the ATM ABR service. We have developed models to determine the network connection parameters required to run interactive client/server multimedia applications over an ATM network using the ABR service. We solve our model using real-time dynamic equilation (RTDE) analysis. We conclude that by proper dimensioning of the buffers at the client and the server, it is possible to run interactive video over the ATM ABR service.Index Terms-Buffer dimensioning, MPEG-2 video, multimedia over ATM systems, video system design.
