Embodiment Construction

[0046] In order to solve the problem that a large number of users apply for multicast to unicast at the same time, resulting in an instantaneous increase in network load, or even a system crash, the embodiment of the present application provides a method for switching from IPTV multicast to unicast. The basic principle is: First, the management server collects the user information of N users, generates a user list according to the user information of N users, and configures the user list to the electronic program guidance server; after the electronic program guidance server receives the program information request sent by the set-top box, according to the program The set-top box identification included in the information request queries the user list. If it is determined that the user list includes the set-top box identification, a program information response is sent to the set-top box. The program information response includes the multicast address of the program corresponding...

Abstract

The embodiment of the invention discloses an IPTV multicast-to-unicast switching method and device, relates to the technical field of network communication, and solves the problems that a large numberof users apply for multicast-to-unicast at the same time, so that the network load is increased instantly, and even the system is collapsed. According to the specific scheme, firstly, a management server collects user information of N users, generates a user list according to the user information of the N users, and configures the user list to an electronic program navigation server; after the electronic program navigation server receives a program information request sent by a set top box, it is determined that a user list comprises a set top box identifier and a program information responseis sent, the program information response comprises a multicast address of a program corresponding to the program identifier and a unicast address of the program, and the set top box requests a multicast stream of the program or a unicast stream of the program. The embodiment of the invention is used for requesting the unicast stream.

Description

technical field [0001] The embodiments of the present application relate to the technical field of network communication, and in particular to a method and device for switching from IPTV multicast to unicast. Background technique [0002] With the increasing development of network technology, streaming media is widely used in many services such as video on demand, online teaching, and online live broadcasting due to its intuition, real-time, and interactive features. Internet Protocol Television (IPTV) is a new type of media information service technology based on telecommunication network technology, Internet technology, broadcast TV network technology and media transmission technology. Both live and on-demand video programs can be watched on the terminal. [0003] In the prior art, some live programs of IPTV transmit the streaming media to the user access network (Content Delivery Network (Content Delivery Network, CDN)) through IP multicast mode. While realizing unicast ...
