Time shifting method for interactive network television system in next generation communication network

Abstract

The present invention provides a time-shifting method for interactive network television system in next generation communication network. The method includes the steps that: the IPTV terminal initiates a living broadcast request, performs interaction with other modules to obtain the location information of the IPTV terminal in the network and the URL information of the content consignation and storage module providing the living broadcast channel service; the IPTV terminal establishes a RTSP link with the control module, the control module establishes a RTSP link with the content consignationand storage module; the content consignation and storage module provides living broadcast content stream to the IPTV terminal; the service control module requests the time-shifting program from the content consignation and storage module, when the IPTV terminal transmits the time-shifting program request to the service control module; the IPTV terminal asks for exiting the multicast channel; and the content consignation and storage module transmits the RTSP time-shifting program flow to the IPTV terminal.

Description

technical field [0001] The present invention relates to a next-generation communication network, and more specifically, to a time-shifting method for an interactive network TV system in the next-generation communication network. Background technique [0002] At present, the frame structure of the next generation communication network (NGN) has been basically determined. In addition to the management level, NGN also includes user level, transport level, business control level and application level. IP Multimedia Subsystem (IMS) is a collection of main functional entities in the service control plane. Registration, authentication, authentication, QoS management and assurance of users and terminal equipment can be realized through IMS; at the same time, IMS supports multiple user access technologies, supports user nomadic and mobility management, and supports interworking with other traditional networks or next-generation networks , Support business integration. IMS is based...

Problems solved by technology

[0004] At present, only ITU and TISPAN are researching the convergence based on NGN and IPTV, and they are still in the initial stage of architecture discussion, and have not involved how to realize the real convergence of IPTV and NGN to provide unified services for the next generation communication network, so that operators can Carry out unified business operation and management to reduce IPTV operation management
