Fig. 2 is the implementation figure of an embodiment of the utility model.

Detailed ways

The embodiment of the utility model will be further described below in conjunction with the accompanying drawings.

Existing digital TV service platforms are also commonly referred to as terrestrial wireless digital TV value-added service platforms, because existing digital TV service platforms, in addition to broadcasting digital TV broadcasts, also provide services such as personalized customization, multimedia information services, data downloads, etc. Services, that is, various interactive TV applications.

The functional service columns (value-added service content) that can usually be provided are: multimedia magazine: including a large amount of data information, expressed in the form of text, pictures, sound, etc.; electronic program guide (EPG): in addition to listing all programs according to various classifications In addition, users can directly enter various sets of digital programs while viewing the program menu; information consultation: including stock market information and weather information. In the column of stock quotes, users can check the real-time stock market quotes and daily K-line charts in real time, and can add the stocks they care about to the "optional stocks" to study the stocks in a targeted manner; TV games: users can use the remote control entertainment on TV, offering educational, sports, and toddler games, among others. At the same time, according to the content, it can also be extended to real estate plaza, life service, leisure and entertainment, talent market, music store, popular music, music audio-visual world and other columns.

In the description of the utility model, the digital TV service platform and the terrestrial wireless digital TV value-added service platform refer to the same.

As shown in Figure 1, the two-way interactive digital TV value-added service platform based on the terrestrial wireless form described in the utility model mainly adds a two-way communication device 2 on the existing digital TV service platform 1, and the two-way communication device 2 It can be a mobile communication device, such as a GSM/CDMA short message modem, or other similar communication devices, such as a PHS short message modem. In the description of this embodiment, the GSM/CDMA short message modem is taken as an example for illustration. The short messages received and sent may include various short messages, such as conventional short messages, multimedia messages or multimedia messages in other ways.

Moreover, a corresponding digital processing connection interface 3 is provided on the digital TV service platform to realize data interaction between the two-way communication device 2 and the digital TV service platform 1 .

Specifically, within the two-way interactive value-added service platform, the two-way communication device 2, such as a GSM/CDMA short message modem, can obtain the playing time of a certain program by sending a data request in a specified format to the digital TV service platform 1, or customize or cancel a certain program. A business etc. The information format is stipulated by the terrestrial wireless digital TV value-added service platform 1, and the user can realize the corresponding function by sending information to the value-added service platform in this format through a terminal such as GSM/CDMA or PHS.

Fig. 2 is the implementation figure of an embodiment of the utility model. As shown in Figure 2, when the utility model is in use, the user first sends a specified format short message to the GSM/CDMA short message modem 2 in the two-way interactive value-added service platform, and the short message modem 2 sends data to the digital TV service platform 1 through the interface 3, The platform 1 processes the data sent by the short message modem again, changes the broadcast status or sends the required information (signal) to the user terminal through the digital TV broadcasting channel, and returns the information on whether the operation is successful or not through the short message modem 2 to the user terminal. user.

In this way, the user can control the terminal to receive relevant digital information (signals) by means of short messages, thereby realizing the short message interaction method of the terrestrial wireless digital TV value-added service platform. The signals used by the digital TV service platform in the utility model include but are not limited to the signals of the terrestrial digital TV standard formulated by China, the signal of the European digital TV standard (DVB-T), the ATSC signal of the American standard and the ISDB-T signal of the Japanese standard , and possibly any digital TV transmission standard signal based on terrestrial transmission in the future.

In order to fully illustrate the utility model, a specific example is given again to set forth:

1. Assuming that there is an existing terrestrial wireless digital TV value-added service platform and supports GSM/CDMA for SMS interaction, the information format is as follows:

Dzyw*1: Indicates customized program 1

Qxyw*1: Indicates cancellation of customized program 1

2. Assuming that a user wants to watch "Program 1" when receiving digital TV programs, but cannot watch it without customization, he can send information in the format of "Dzyw*1" to the value-added service platform through GSM/CDMA-based communication equipment GSM/CDMA server.

3. After receiving this information, the GSM/CDMA server will call the value-added service platform through the corresponding interface, and notify the platform that the user has customized program 1.

4. The value-added service platform determines whether the user can be authorized to watch according to the attributes of the program 1 (such as whether to deduct fees), if the authorization is successful, it will notify the GSM/CDMA server that the authorization has been successful, and simultaneously enable the user to watch the program 1. authority.

5. The GSM/CDMA server sends the authorization information from the value-added service platform to the user through a message.

6. At this point, the user can watch the customized program, thereby realizing the two-way interaction of the wireless digital TV value-added service platform.

To sum up, the utility model realizes information interaction in a true sense by adding two-way communication equipment to the original digital TV technology platform and using built-in mobile communication equipment. The utility model satisfies the individualized needs of users, and enables users to receive data actively instead of passively receiving information in the past. The right to speak, so that digital TV can truly serve the public.

The above are the best implementation modes of the present utility model. According to the disclosed content of the present utility model, some similarities and alternatives that those skilled in the art can obviously think of should fall into the protection scope of the present utility model.
