Problems solved by technology

Due to the influence of bandwidth and other factors, the 3G network can provide limited program content, and the cost is relatively high
[0016] The satellite digital multimedia broadcasting system currently used in my country is DVB-S technology, but this standard solution is usually only suitable for fixed receiving equipment, and cannot provide mobile video broadcasting for mobile terminal equipment.
In addition, the terrestrial multimedia digital broadcasting systems currently adopted by other countries in the world, such as DVB-H in Europe, media FLO in Qualcomm and T-DMB in South Korea, are costly to achieve wide coverage, and are difficult to achieve in areas with complex terrain

Embodiment Construction

[0051] The present invention mainly adopts the combination mode of satellite DMB network and ground DMB network, wherein, described satellite DMB network comprises: business center, ground station and satellite; Described ground DMB network comprises: satellite signal receiving antenna and Transmitter (transmitter ). The present invention mainly replaces the existing repeater equipment by using a Transmitter in the ground DMB network. The Transmitter is used to perform frequency conversion and power amplification on the satellite signal, and uses a frequency different from that of the satellite transmitted signal to convert the The program signal is sent out to be received by the mobile terminal, thereby achieving the purpose of reducing the number of devices and providing rich digital multimedia broadcasting services for mobile terminal devices.

[0052] Because the present invention relates to the breadth and depth of satellite signal coverage, and the characteristics of the...

Abstract

The invention relates to a multimedia broadcasting system, it includes satellite DMB network and land DMB network. The satellite DMB network includes: satellite signal receiving antenna for receiving satellite signals; transmitter for receiving relative satellite signals from the antenna and conducting frequency conversion and amplification process and sending the processed signals adopting such frequency different from that of satellite signal; mobile terminal for receiving the signals from the transmitter. The invention adopts transmitter to replace current repeater, in which the number of apparatus and cost are reduced.

Description

technical field [0001] The invention relates to the technical field of mobile multimedia broadcasting, in particular to a system for realizing mobile multimedia broadcasting. Background technique [0002] With voice and wireless Internet data service growth slowing down and profits declining, as well as more service demands from users of handheld devices, operators need to develop into new business areas. Under such circumstances, the emergence of digital multimedia broadcasting technology has brought opportunities for integration and new development opportunities for broadcasting media whose business space is becoming saturated and telecom operators whose business income is sluggish. As a symbolic service of the integration of the two industries, the field of mobile video broadcasting has attracted extensive attention from operators and users. [0003] At present, there are two ways to realize mobile terminal video services: one is based on the 3G network provided by mobil...
