Description

Interactive system and method for mobile multimedia broadcasting

The present invention relates to the field of communications technologies, and in particular, to an interactive system and method for mobile multimedia broadcasting. Background technique

After experiencing the game period of the market, especially the triple play, the China Mobile Multimedia Broadcasting System (CMMB) mobile TV standard with China's independent intellectual property rights has basically ushered in a good situation. Naturally, CMMB broadcast network and communication Network, including but not limited to time division-synchronous code division multiple access (TD-SCDMA), wideband code division multiple access (WCDMA), code division multiple access 2000 (CDMA2000) systems, etc., and technology integration with the Internet (Internet) network Complementation is inevitable.

The State Administration of Radio, Film and Television has a frequency band of 470MHz-798MHz, which is not only superior to the 3G frequency band currently mastered by telecom operators in terms of wireless transmission characteristics, especially the CMMB broadcast network has great advantages in coverage, making it necessary to build fewer launchers. The investment is low, and the communication network (including but not limited to TD-SCDMA, WCDMA, CDMA2000 communication network) and Internet network that are not covered by the vast rural and urban-rural joints can be covered in the future. Although CMMB is a broadcast mobile TV technology, the characteristics of broadcasting technology make it have obvious advantages in multi-channel and wide-range signal coverage. Watching TV programs on CMMB broadcast network is cheap, does not go traffic, but for CMMB. In other words, the characteristics of the one-way network make it impossible for users to interact with the program content, and the interactive on-demand function cannot be realized.

In theory, WCDMA, TD-SCDMA-based Multimedia Broadcast Multicast Service (MBMS) and CDMA2000-based Broadcast Multicast Service (BCMCS) enable telecom operators to provide broadcast and mobile subscribers with broadcasts through their deployed base stations. Multicast video service. This way The mobile TV service can also provide users with interactive on-demand services by taking advantage of the upstream bandwidth of 3G networks. Communication networks (such as MBMS, BCMCS) can provide two-way interactive mobile TV services. However, as consumers' demand for Internet video services grows, bandwidth has become a bottleneck. In urban densely populated areas, the bandwidth allocation of base stations themselves is relatively tight. If a large number of users use video multicast services, it will inevitably cause congestion in the wireless network, which in turn affects the user experience. Summary of the invention

To solve the above technical problem, the present invention provides an interactive system for mobile multimedia broadcasting, the system comprising a mobile multimedia broadcast CMMB service and an interactive control device, wherein the CMMB service and the interactive control device are configured to receive a CMMB terminal transmission through a two-way network. The interactive service request information including the service requested by the CMMB terminal, and the service content requested by the CMMB terminal is sent to the CMMB terminal via the CMMB broadcast network according to the interactive service request information.

Further, the business content is provided by a content/service provider server.

Further, the two-way network includes a communication network and an Internet network.

Further, the CMMB service and interaction control device comprises a content management platform, a data broadcast platform and an interactive service platform.

The present invention also provides a method for mobile multimedia broadcast interaction, the method comprising the following steps: The mobile multimedia broadcast CMMB service and the interactive control device receive the interactive service request information sent by the CMMB terminal and include the service requested by the CMMB terminal through the two-way network. The mobile multimedia broadcast CMMB service and the interactive control device send the service content requested by the CMMB terminal to the CMMB terminal via the CMMB broadcast network according to the interactive service request information. The method further includes: the mobile multimedia broadcast CMMB service and the interactive control device send the information display to the CMMB terminal through the two-way network, where the information display is used by the CMMB terminal to send an interaction to the mobile multimedia broadcast CMMB service and the interactive control device according to the information display. Business request information.

The invention utilizes the existing network conditions to provide an uplink network loop for the CMMB mobile TV technology, realizes the interaction of the CMMB terminal, and solves the network congestion problem caused by the two-way network transmitting the audio and video programs in the downlink, thereby saving the network cost.
