“…VOD services include a much wider range of services and opportunities. VOD services have become feasible due to the availability of a number of enabling technologies such as MPEG [4], ATM [5,6], ADSL [7] and HFC with the maturity of two physical and medium access control protocol standards, i.e. IEEE 802.…”

SUMMARYAccording to the MPEG-1/2 standard, full motion video can be compressed and stored in an information warehouse. Multiplexing with normal voice calls, it is retrieved and delivered to the customer's local BISDN central o$ce via 155 Mb/s trunks. These voice calls have higher priority than video-on-demand (VOD) so that normal voice services will not be in#uenced by VOD transmission. The number of voice calls always #uctuates in real-time. Thus, an e$cient tra$c control scheme is highly desired to guarantee a given level of performance and achieve as great as possible use of available bandwidth. Based on the fact that the number of real-time voice calls is variable, and the use of available capacity is less than 100 per cent, this paper will present an e$cient tra$c control scheme for store-and-forward VOD services, and demonstrate the scheme by various simulation results.

“…Digital Network offers two kind of access interfaces [7] i)BRI Basic Rate Interface 2B + D where the bit rate of B channel is 64 Kbps and for D channel is 16 Kbps. The B channel can be used for visual communication with low video quality (Fig.3).…”

We propose and investigate many different options for video communications like SW56, SMDS, ISDN AND POTS. We consider freeze frame system for video transmission at low data rates on copper pairs to the multiple users at remote locations. Freeze frame video system transmits data or picture @ 5 frame per second (FPS) rate dependent upon the activity in the picture with the SNR greater then 30 dB at very low cost. This system is designed specifically for the real time surveillance of highways by video cameras.

“…Using HDSL [7] over short distances gives up to 1 Mbit/s, and using ADSL-I, -11 or -111 bit rates of 1.5 , 3 and 6 Mbit/s respectively can be provided over progressively shorter distances. Additional copper pairs can be employed to increase bandwidth.…”
