Abstract
The integrated digital multimedia video service can be delivered via different network media such as Hybrid Fiber Coax (HFC) and Fiber to the Curb (FTTC). Asynchronous Transfer Mode (ATM) can be used as an effective transport mechanism for the digital video services, such as MPEG-2. Both the lower layer physical network topology/characteristics and network protocols impose special technical constraints on the overall digital video system design.
The system issues on network delivery of digital video discussed in this paper include: (1) Overall network impact and system protocol stack for HFC and FTTC video delivery; (2) Interactivity of digital video and its signaling; (3) Quality of Service (QoS) impact on digital video coding algorithm.
Finally, the future directions on the networked video field are discussed and implementation choice and migration strategy are briefly analyzed.
