The present invention relates to an interactive mobile television system and a method thereof for use in a mobile terminal device, relating to an interactive mobile television service system applied to a mobile terminal device device, and particularly to a method for generating a mobile television program content and a combination thereof A system for providing action community services on mobile terminal devices.

From the current technical point of view, mobile TV can be divided into two types: broadcast and streaming. The broadcast mobile TV technology is provided by a plurality of high-power transmission stations (Transmission Tower) with a plurality of small power filling stations (Gap Filler). The signal of the service area covers a one-way communication system. The advantage of broadcast mobile TV technology is that there is no capacity limitation. No matter how many people in the service area receive signals at the same time, the required bandwidth is fixed. An example of broadcast mobile TV technology is DVB-H (Digital). Video Broadcasting for Handheld), T-DMB (Terrestrial Digital Multimedia Broadcasting), and MediaFLO (Media Forward Link Only). The disadvantage of broadcast mobile TV technology is the lack of two-way interaction and the inability to select video on demand (VOD, Video On Demand). )Applications. Therefore, it is necessary to provide two-way interactive value-added services such as voting, prize-winning and online betting through the assistance of the communication network. On the other hand, streaming mobile TV uses a well-known mobile communication network as a platform, such as 3G WCDMA. (Wideband Code Division Multiple Access), 3.5G HSPA (High Speed Packet Access), and WiMAX (Worldwide Interoperability for Microwave Access) provide services for enjoying mobile TV. It is a two-way communication system; therefore, streaming TV is very It is easy to provide two-way interactive services, but the disadvantage is that there is a capacity limit. Taking the 3.5G HSPA system as an example, the current maximum transmission rate of a commercial system is 7.2 Mb/s, and the rate required to transmit a streaming movie is 384 Kb/s, so that only 18 people can simultaneously watch TV at the same time. As can be seen from the above discussion, there is a trade-off relationship between video on-demand and capacity (Trade-Off); whether it is broadcast or streaming mobile TV technology, there are currently two shortcomings:

1. Passive TV programs: TV programs are broadcast in accordance with a pre-arranged program schedule (Linear Programming) or video content is pre-designed by the media company, and the programs viewed by the viewers within the scope of the signal are the same; Therefore, the audience's participation in the production of the program content is relatively low, and for the TV company, the production cost of the program is high, and it is easy for the viewer to lose the freshness of the program content;

2. Lack of relevance between viewers: viewers of traditional wireless TV or mobile TV, although watching the same TV program content at the same time, are not connected to each other and cannot be connected to each other. Interacting; therefore, for TV companies, there will be no opportunity to increase the value-added revenue, which is limited to the fixed income dilemma; and for the audience, the emphasis on active participation and community concept today can not meet the needs of the audience. .

It can be known from the above discussion that the provision of traditional mobile TV programs will not be able to support the survival of the mobile TV service, nor will it satisfy the audience's preferences, and it is necessary to develop novel value-added application services. The conventional digital and mobile television technology provides information about the broadcast of a television program by an electronic program guide (EPG) or an electronic service guide (ESG), which is mentioned in the following prior patent technologies. Relevant concepts of similar architectures and methods (133603 and 168190); in addition, improvements have been mentioned in previous patent technologies (200638227, 200705995 and 200824457) to facilitate and speed up the display and review of information related to programs and services. The approach to implementing interactive services in digital and mobile television systems has been mentioned in previous patented technologies (158130, 158474 and 169354) for similar architectures and methods; however, the above invention still only considers one-way broadcasting. Additional useful information is provided in the path, which is then selected by the viewer through an electronic program form or an electronic service form. Since the mobile communication network is not integrated, the service type and benefits that can be provided will be quite limited.

It can be seen that there are still many shortcomings in the above-mentioned methods of use, which is not a good design, but needs to be improved.
