Embodiment 1

[0077] see figure 2 , which is a flowchart of a method for multimedia data communication provided in this embodiment, specifically includes:

[0078] 101: The mobile multimedia broadcasting wireless terminal device receives access requests sent by various user terminals, each access request includes a channel identifier of the target multimedia data requested to watch and an identifier of the user terminal.

[0079] 102: The mobile multimedia broadcast wireless terminal device assigns IP multicast addresses to each user terminal, and divides the IP multicast addresses of user terminals with the same channel ID of the target multimedia data requested to watch into the same multicast group.

[0080] Wherein, the mobile multimedia broadcast wireless terminal device divides at least one multicast group.

[0081] Optionally, the range of IP multicast addresses assigned by the mobile multimedia broadcast wireless terminal equipment to each user terminal may be 224.0.0.0-239.255.25...

Embodiment 2

[0087] see image 3 , is a flow chart of a multimedia data communication method provided in this embodiment. In this embodiment, three user terminals request to watch target multimedia data from mobile multimedia broadcasting wireless terminal equipment, and the multimedia data channels requested to watch are the same as an example. Be specific.

[0088] A flow chart of a method for multimedia data communication, specifically comprising:

[0089] 201: The mobile multimedia broadcasting wireless terminal device receives access requests sent by three user terminals, and each access request includes a channel identifier of the target multimedia data requested to be watched and an identifier of the user terminal.

[0090] It should be noted that multimedia data channels are divided into encrypted channels and non-encrypted channels. The maximum number of user terminals that can be accessed by each non-encrypted channel of the broadcast wireless terminal equipment has a certain u...

Embodiment 3

[0135] see Figure 8 , is a flow chart of a multimedia data communication method provided in this embodiment. In this embodiment, four user terminals request the mobile multimedia broadcasting wireless terminal device to view target multimedia data, and the multimedia data channels requested to be viewed are not the same as an example. The invention is described in detail.

Abstract

The invention provides a method, apparatus and system for multimedia data communication and belongs to the field of communication. The method comprises the following steps of: receiving the access requirements sent by each user terminal; respectively allocating an IP (internet protocol) multicast address to each user terminal, dividing the IP multicast addresses of the user terminals with the same channel identifier of the target multimedia data required to be watched into the same multicast group; transmitting the requirement used for obtaining the target multimedia data to a mobile multimedia broadcasting system, wherein the requirement comprises the channel identifier of the target multimedia data; receiving the target multimedia data transmitted by the mobile multimedia broadcasting system; and broadcasting a target multimedia data pocket of each user terminal to each user terminal in the same multicast group. According to the invention, the purpose of simultaneously providing the multimedia data service to multiple users by one mobile multimedia broadcasting wireless terminal apparatus can be fulfilled.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method, device and system for multimedia data communication. Background technique [0002] The mobile multimedia broadcasting system is a system that can provide multimedia data services to various user terminals such as mobile phones and notebook computers. For example, China Mobile Multimedia Broadcasting (CMMB) and the Japanese and Latin American mobile TV standard ISDB-T ( Integrated Services Digital Broadcasting-Terrestrial), European mobile TV standard DVB-T (Digital Video Broadcasting-Terrestrial) and European mobile TV standard DVB-H (Digital Video Broadcasting-Handheld), etc. When users watch TV programs through user terminals such as mobile phones and notebook computers, they need to use a wireless terminal device that supports the mobile multimedia broadcasting system. ) module, a WiFi (Wireless Fidelity, Wireless Fidelity) module and a CMMB module to connect to th...
