Embodiment 1

[0046] Embodiment 1, the building advertising TV is playing a restaurant advertisement, and the GFSK modulation and demodulation method is used to send the restaurant discount coupon from the building advertising TV to the mobile phone.

[0047] The specific implementation steps are as follows:

[0048] Step 1-1. The content of the discount coupon sent is FC123456789. In the character code conversion module, the characters of the discount coupon are converted into binary data using the ASCII code format.

[0049]

[0050] Step 1-2. Perform CRC-8 check on the above binary data, and insert the CRC check digit into the back of the original binary data, as shown in Table 1:

[0051] Table 1: Code after CRC check

[0052]

[0053] Step 1-3. Convolutional encoding is performed on the above data, and a preamble is inserted after encoding to complete the data packet. As shown in table 2:

[0054] Table 2: Packets after convolutional encoding

[0055] Step 1-4. In the acoust...

Embodiment 2

[0063] Embodiment 2. The TV station code, time and advertisement index number are embedded in the opening advertisement of a certain cable TV station, and the information is sent to the remote server through the user's tablet computer to make audience statistics and lottery vouchers. The modulation method uses 2ASK. The specific implementation steps are as follows:

[0064] Step 2-1. Determine the data structure of the information bit as shown in Table 3, wherein the time code is dynamically generated according to the playback time:

[0065]

[0066] TABLE 3: INFORMATION BIT DATA STRUCTURE

[0067] Step 2-2. In the information coding module, perform a CRC-16 check on the code, and the data after the check is shown in Table 4:

[0068]

[0069] Table 4: Data structure after CRC check

[0070] Step 2-3. Perform convolutional coding on the data in Table 4, insert the preamble after the convolutional coding, and complete the data packet coding.

[0071] Step 2-4. In the ...

Abstract

The invention relates to a method and a system for sending information from a television to a mobile terminal. The method comprises the steps of: processing the information sent from the television to the mobile terminal through a sound wave information generating module, so as to generate an audio code; embedding the audio code into the original television content, and playing through the television; sending the information to the mobile terminal of an audience by utilizing sound; receiving a sound signal through a microphone of the mobile terminal of the audience; and restoring the sent information through sound wave information receiving software in the mobile terminal, and transmitting the sent information to a service processing module for implementing follow-up services, so as to achieve the sending of the information between the television content and the audience. The method disclosed by the invention is implemented through the mobile terminal by utilizing the software; and the content of a played program is subjected to simple information processing at a program source side, and is played by using the current television without hardware transformation and equipment update.

Description

technical field [0001] The invention relates to the field of TV and mobile phone applications, in particular to a method and system for sending information from a TV to a mobile terminal. Background technique [0002] Television is a broadcasting medium with a wide audience and great influence. In recent years, with the development of technology, various forms such as building advertising TV, bus-mounted TV, mobile TV, IPTV, and digital cable TV have emerged. At the same time, with the development of the TV form, TV programs have appeared in TV programs such as TV shopping and building advertisements, which use TV media to achieve product recommendation and sales, enriching and expanding the use of the original TV media. [0003] With this kind of content promotion with the theme of advertising and shopping, the interaction between TV content and audience has become a necessary business requirement. At present, building TV advertisements and TV shopping channels are mainly...
