Problems solved by technology

Although mobile TV CMMB and cellular network TD-SCDMA respectively provide channels for broadcast video and two-way interaction, this platform does not allow users to interact dynamically with rich media on mobile TV
This is mainly because the current CMMB technology cannot realize dynamic rich media applications, and the only rich media is a purely static browser user interface. Another problem is that CMMB does not have an uplink channel, so interactive applications cannot be realized

Embodiment Construction

[0021] In the following embodiments, the dynamic rich media interaction technology based on the integration of CMMB mobile phone TV and cellular network is described, wherein the cellular network can be a 2G network, such as a GSM network, or a 3G network, such as a WCDMA network or TD-SCDMA network. If there is no special description, in the context of the present invention, dynamic rich media is referred to as rich media for short.

[0022] First, a dynamic rich media scene and its generation and transmission are described. The dynamic rich media scene technology describes how to encode rich media content and transmit and decode rich media resources in a unified format on various communication channels and devices. These rich media resources include but are not limited to audio, video, vector graphics, text, pictures, etc. Such as Figure 4 As shown, the basic function of the rich media scene description technology is to describe the layout of rich media content elements ...

Abstract

The invention provides a dynamic interaction method and a dynamic interaction system of a CMMB (China Mobile Multimedia Broadcasting) mobile television, aiming to provide a dynamic interaction function based on rich media at a CMMB mobile television terminal. In the method, dynamic rich media scene description data and rich media content elements are carried in a CMMB multiplexing frame of a server end, and the CMMB multiplexing frame is sent to a mobile terminal from the server through a CMMB downlink channel; the CMMB multiplexing frame is received at the mobile terminal, and the rich media scene description data and the rich media content elements in the CMMB multiplexing frame are extracted; then the rich media content elements are combined into a rich media form according to the rich media scene description data and presented to a terminal user; and a remote interaction event generated by the user through operation at the terminal can be sent to the server from the mobile terminal through a cellular net interaction channel.

Description

technical field [0001] The invention relates to an interactive mobile phone TV integrated with a CMMB and a cellular network, in particular to a dynamic interaction method and system for a CMMB mobile phone TV. Background technique [0002] Watching streaming media on devices based on GSM, GPRS and TD-SCDMA is usually through on-demand and unicast methods. For each user, a one-to-one streaming media connection needs to be established. The more the number of users, the consumed cellular network There are also more bandwidth resources, so the unicast method will increase the load of the cellular network and affect the effect of video playback. In addition, multicast technologies such as MBMS (Multimedia Broadcast and Multicast Service) can also be used to implement streaming media applications on cellular networks. Numbers are still limited. [0003] Mobile TV is based on a huge mobile phone user base and has a great market prospect. The most promising mobile TV standard in...
