Problems solved by technology

However, the content of the mobile multimedia service is various, and there are many devices providing the content of the mobile multimedia service, and the protocols and messages adopted for the data output of each device are different. At present, between the mobile multimedia service device and the multiplexer A large number of proprietary protocols and message transmission are used, and there is no unified transmission method, which is not conducive to the construction of mobile multimedia networks and the interconnection and intercommunication between devices

[0034] refer to image 3 , below take mobile multimedia service equipment to adopt UDP transmission protocol and multiplexer to carry out data transmission as example, in conjunction with accompanying drawing, the present invention is described in detail, specifically comprises the following steps:

[0035] Step 1: the mobile multimedia service device encapsulates the mobile multimedia service data into a multiplex transmission message;

[0036] The mobile multimedia service equipment encapsulates the mobile multimedia service data into Figure 4 As shown in the multiplexed transmission message, the encapsulation structure of the multiplexed transmission message includes two parts: a message header and a message body. The message body of the multiplexed transmission message contains mobile multimedia service data, for example: ESG data, program prompt information, data broadcast, emergency broadcast information table, ESG basic description table, etc.

[0037] The message he...

Abstract

The present invention provides a transmission method of multiplexing data stream, including: a business apparatus firstly packaging business data into a multiplexing transmission message; and then, according to User Datagram Protocol(UDP) or Transfer Control Protocol(TCP), packaging the multiplexing transmission message into a UDP message or a TCP message and transmitting to a multiplexer. The method unionizes the data transmission method between the business apparatus and the multiplexer, thereby resolving the interconnection and intercommunication problem between network devices.

Description

technical field [0001] The invention relates to the technical field of mobile multimedia broadcasting, in particular to a method for transmitting multiplexed data streams of mobile multimedia broadcasting services. Background technique [0002] Mobile multimedia broadcasting is a broadcasting multimedia playback technology that has emerged in recent years. It can watch multimedia services such as TV through a handheld terminal while moving at a high speed. The terminal can receive the multimedia service program list through the wireless broadcast channel, select the channel that it has the right to watch, and then receive the multimedia data of the selected channel, so as to realize watching multimedia services such as TV on the mobile terminal. [0003] The mobile multimedia broadcasting standard GY / T 220.1-2006 defines that in the mobile multimedia broadcasting system, data streams are transmitted in the form of multiplexed frames. A multiplexed frame is composed of multip...
