Problems solved by technology

However, when a user switches from a mobile network that supports multicast services to other networks, such as broadband networks, video services will be interrupted. For example, eMBMS is based on LTE (Long Term Evolution, Long Term Evolution) networks. When users When leaving the LTE network, the video service the user is using will be interrupted

Embodiment Construction

[0031] The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0032] An example of the media playing method of the present invention is figure 1 shown.

[0033] In step 101, the client is located in the multicast network, and plays the multicast program according to the multicast program index in the program index, wherein the program index includes a unicast program index in addition to the multicast program index.

[0034] When step 102 occurs and the client leaves the multicast network and connects to the unicast network, step 103 is executed, and the client plays the unicast program according to the unicast program index in the program index.

[0035] The multicast program and the unicast program are the distribution of the same program on the multicast network and the unicast network respectively.

[0036] The DASH (Dynamic Adaptive Streaming over HTTP, dynamic adaptive st...

Abstract

The invention provides a media playing method, a media playing device, a media providing device and a media playing system and belongs to the multi-media technology field. The media play method comprises steps that, a multicast program is played in a multicast network according to a multicast program index in program indexes, and the program indexes further comprise a single playing program index; when switching from the multicast network to a single playing network is carried out, a single playing program is played according to the single playing program index in the program indexes; the multicast program and the single playing program are one same program and are respectively published in the multicast network and the single playing network. Through the method, the single playing program in synchronization with the multicast program can be continuously played when switching from the multicast network to the single playing network is carried out, and thereby program playing is realized without interruption.

Description

technical field [0001] The present invention relates to the field of multimedia technologies, in particular to a media playing method and device, a providing device and a playing system. Background technique [0002] With the widening of mobile network bandwidth and the improvement of transmission efficiency, video multicast services using mobile networks have become the focus of development, such as MBMS (Multimedia Broadcast Multicast Service, Multimedia Broadcast Multicast Service), eMBMS (Enhanced Multimedia Broadcast Multicast Service ) are well developed. However, when a user switches from a mobile network that supports multicast services to other networks, such as broadband networks, video services will be interrupted. For example, eMBMS is based on LTE (Long Term Evolution, Long Term Evolution) networks. When users When leaving the LTE network, the video service that the user is using will be interrupted. Contents of the invention [0003] The purpose of the pres...
