“…Furthermore, some of our previous studies [NG91,NG93A,NG93B,NG93C] have shown that the timed token MAC protocol is suitable for real-time communication and multimedia application within a local area network (LAN). The main idea behind the timed token MAC protocol is to control the sharing of network bandwidth among the stations for transmitting synchronous messages.…”

This paper presents three transmission schemes to improve the transmission of MPEG video over a timed token medium access control (MAC) network. Multiple classes of MPEG video IntroductionBecause of the demands of the videos on network bandwidth, video data needs to be compressed before being transmitted over a computer network. Many compression schemes have been proposed or developed for these variable bit rate (VBR) video services. Of all these video compression schemes, the scheme developed by the Moving Pictures Experts Group (MPEG) is the most notable. By MPEG standard, video information is compressed frame by frame, and the resultant frames should be transmitted and processed under stringent timing constraints. To support such applications on top of a computer network, the underlying transmission scheme must ensure that most, if not all, frames should reach their destinations before their deadlines. Frames arriving late and missing their deadlines will result in a poorer quality of the picture or jumpy video. Hence, it is a tradeoff between video quality and on-time delivery of video frames.In order to address the issue of on-time video frame delivery, transmission delays for the underlying network must be deterministic and bounded. Here, we adopted the time token medium access control protocol because of its important property of bounded transmission delay. This bounded delay property is a necessity for real-time communications, multimedia computing systems, and industrial process controls. This is why the timed token MAC protocol has been well received and being adopted in several high-bandwidth network standards over the years.

A study on transmitting MPEG-I video over a FDDI network

This paper presents two schemes to improve the transmission of real-time MPEG-I video over a FDDI network. Multiple classes ofMPEG-I video will be used in the study and what makes this simulation study different from the others is the different kinds of MPEG-I video data we used. These data are captured from real video programmes and we categorized these video clips according to their workload characteristics. The performance of the FDDI network is examined in terms of the maximum number of MPEG-I video streams got transmitted over the network without missing their deadlines. This simulation study observed that by employing the Intentional-delay scheme, we can improve the performance by an average of 35%. From another set of simulation experiment, when applying the Framegrouping scheme for MPEG-I transmission, we can improve the performance up to 150%.10 0-8186-7626-4196 $5.00 0 1996 IEEE
