Embodiment Construction

[0032] The present invention can be applied to an interactive service content distribution system based on an HFC network that requires dynamic bandwidth management. The present invention can also be applied to interactive service systems including but not limited to time-shifted TV (TVOD), video on demand (VOD), network personal VCR (Network Personal Video Recorder, NPVR), switched broadcast (switched broadcast), on demand distribution of television programming (ODDTP), digital on-demand TV service (swtiched digital video, SDV), IP voice (Voice over IP, VoIP) and other business systems.

[0033] figure 1 It is an overall system architecture diagram of two-way cable television network interactive services, including SRM server, MS, IP network, IPQAM, HFC network, STB and other main components.

[0034]Among them, the MS, the SRM server, and the local area network formed by the IP network connection form the front-end part of the system; the front-end part of the system also i...

Abstract

The invention relates to the cable communications field and provides a method for managing the interactive service of a cable TV network. Resource allocation and resource recycling are performed through registration and session with set-top box equipment, session and an SRM server to allocate and manage interactive service resources, thereby maximizing the utilization ratio for bandwidth resources and ensuring that the amount of maximum bandwidth resources needed for operation does not increase linearly along with the increase of media content. Therefore, the flexibility of a system is enhanced, the system response time is shortened, and the system is enabled to automatically recover from abnormal conditions.

Description

technical field [0001] The present invention relates to the field of wired communication, and more specifically, the present invention relates to a method for managing interactive services of a cable TV network. Background technique [0002] The traditional cable TV network distributes the program data through the hybrid fiber-coaxial network (HFC), and only provides one-way broadcast service for users in the network area. The HFC network has the advantages of wide frequency range, large capacity, low cost, strong anti-interference ability, supporting multiple services, and connecting thousands of households, laying a foundation for the development of digital TV technology. With the development of digital TV technology and the gradual integration of digital TV technology and IP technology, providing users with more interactive two-way interactive video services will become the development direction of cable television networks. Two-way interaction refers to data interaction...
