Abstract
The Broadband Integrated Services Digital Network (BISDN) is a new concept for exchange area communications. Based on lightwave technology, high-speed circuit and packet switching, and intelligent networking, BISDN will integrate services such as voice, data, video, LAN (Local Area Network), and MAN (Metropolitan Area Network) under the same umbrella as POTS (Plain Old Telephone Service). Among various components of the BISDN, the cell-based ATM (Asynchronous Transfer Mode) multiplexing technique is a powerful vehicle for providing integrated services effectively. Among various services envisaged for BISDN, high-quality video may be the most attractive new service for the majority of residential customers. Therefore, the digital coding of high-quality video signals in a form suitable for transmission through the proposed BISDN network is of great interest and importance. The coding of ATV (advanced television) for digital transmission is of particular importance since it may represent the most viable means for avoiding transmission impairments and delivering very high image quality. The target rate for the coding of the ATV signal is the currently proposed CCITT H4 rate of roughly 135 Mbps, which is the BISDN payload of the SONET channel. In this paper, we review the structure of the BISDN and effective digital coding of ATV at about 135 Mbps. We also address issues related to transmission of compressed ATV over the cell-based ATM networks.
