Embodiment 1

[0044] This embodiment provides a multimedia service transmission method, the method is based on the real-time conditions of the network communication between the terminal and the multimedia provider and the real-time state of the terminal processing capability to transmit the multimedia service, that is, the terminal needs to notify the multimedia service provider The real-time status of the relevant terminal in order to negotiate the best multimedia service experience. The implementation of this method is as follows figure 1 As shown, including the following operations:

[0045] Step 100, the terminal obtains the currently available network transmission rate, and obtains the decoded output code rate of the multimedia content with the same service attribute as the applied multimedia service;

[0046] The service attributes of the above-mentioned multimedia services include at least the code rate of the multimedia service content, and one or more of the following information:...

Embodiment 2

[0082] figure 2 As shown, it is a system structure diagram in the embodiment of the present invention, showing the service interaction between the terminal equipment and the multimedia service provider. In the prior art, a terminal usually initiates a service request to a multimedia service provider, and the multimedia service provider delivers multimedia content to the terminal. During this process, the terminal usually informs the multimedia service provider of the multimedia capabilities supported by the terminal, such as requirements such as multimedia format, multimedia resolution, and code rate, through SDP files or UA Profiles or other means. But it does not take into account the real-time conditions of network communication and the real-time status of terminal processing capabilities. Therefore, the applicant proposed that the terminal should inform the multimedia service provider about the real-time status of the terminal, so as to negotiate the multimedia service w...

Abstract

A method and terminal for transmitting a multimedia service. The method comprises: a terminal acquiring a currently available network transmission rate, and acquiring a decoding output bitrate of multimedia content of which the service attributes are identical to those of an applied multimedia service; the terminal at least sending a smaller value of the acquired network transmission rate and the decoding output bitrate of the multimedia content to a multimedia service provider; and the terminal receiving multimedia service content matched and sent by the multimedia service provider according to the smaller value of the network transmission rate of the terminal and the decoding output bitrate.

Description

technical field [0001] The present invention relates to the communication field, and more specifically relates to a multimedia service transmission method and terminal equipment. Background technique [0002] With the development of mobile communication technology and the popularization of intelligent terminals, mobile multimedia services are also developing faster and faster. Users can enjoy rich multimedia services through mobile smart terminals, such as mobile TV, online high-definition video, and so on. When a terminal uses multimedia services, it usually conducts capability negotiation with a server or other terminal that provides multimedia services, and informs the other party of the device capabilities of the terminal, such as supported multimedia formats, resolutions, bit rates, etc. After the capability negotiation is passed, the adaptation The multimedia content of the terminal can be delivered to the terminal for display. But this existing technology considers ...
