1. When I first started making Tiger Tiger Connect, there were instructions in the box, and the hardware of Tiger Connect was assembled according to the instructions. It is suggested that all components should be firmly connected during assembly to ensure the design specifications at the factory and achieve the best acceptance effect.
2. Connect the satellite receiving port of the set-top box with the tuner of the satellite receiving equipment through the data cable, turn on the power of the set-top box, turn on the humanized service, open the humanized system menu and switch to the "System Settings" tab.
3. In the "System Settings" tab, press the "OK" button on the remote control. In the pop-up "System Settings Requires Password" interface, enter the password "9999" for advanced authorization setting, and press the "OK" button to enter.
4. In the "Installation and Signal Detection" interface, switch to the "satellite" mode, and adjust the elevation angle and direction angle of the home communication receiving equipment according to the local actual situation, so that the "signal strength" reaches 70% and the "signal quality" reaches 30% to receive satellite signals normally.
5. In the whole debugging process of Huhhot satellite, the most complicated part is the debugging of elevation angle and direction angle of Huhhot receiver. There are related satellite parameter information in the package box of HuHuTong, which can greatly improve the debugging efficiency. As shown in the figure:?
6. After the signal debugging is completed, there may be a prompt that "the channel is not authorized, so you can't watch TV programs normally". Just wait patiently for a while to solve it. You can also switch to channel 999 and follow the on-screen prompts to quickly complete the account authorization operation.
7. In addition, in the process of using HuHutong, we will also encounter prompts such as "location module is abnormal", "location service has changed" or "location information has changed, please contact customer service center". In this case, we need to relocate the account.
The specific method is as follows: Switch to the "Restore Factory Settings" tab and press the "OK" button on the remote control to restore the factory settings.
8. Then switch to the "Network Connection Settings" tab, set the "Transmission Protocol" to "TCP", set the "Network IP" to the IP as shown in the figure, and set the "Network Port Settings" to "04567".
9. Switch to the "Area Code" tab and fill in the "Huhutong Area Editor" according to the first six digits of the local ID card or the "administrative area code".
10. Next, we need to perform an important step: turn off the power of the set-top box, open the back cover of the set-top box, insert the local mobile phone card into the SIM card slot, and insert any local home encryption card at the same time. Turn on the mobile phone, wait for the "abnormal location module" prompt window, and turn off the power of the set-top box.
1 1. Reinsert the original encryption card and turn on the power of the set-top box. If after waiting for more than 10 minutes, there is still no prompt information about "Location", then the location has been successfully migrated. Enter the "System Settings" interface again and switch to the "Base Station Information" tab. After the "base station information" appears, you can watch TV programs with the account.

The DTH service is a new DTH service organized and implemented by the State Administration of Press, Publication, Radio, Film and Television with the approval of the Propaganda Department of the CPC Central Committee, in order to implement the spirit of the instructions of the central leadership and solve the problem that people in rural areas can't hear or see radio and television for a long time as soon as possible. ?
The direct broadcast satellite "Huhutong" is the lowest cost, fastest and most effective way to fundamentally solve the problem of listening to radio and watching TV in the vast rural areas of China, which is conducive to narrowing the gap between urban and rural areas, accelerating the equalization of radio and television services between urban and rural areas, and allowing rural people to enjoy the fruits of China's reform and opening up.
Local service institutions must be authorized by the management center, and the application conditions are as follows: obtaining the installation service license of satellite ground receiving facilities issued by the administrative department of radio, film and television of this province; Engaged in local radio and television transmission services for more than 2 years, with the ability to provide users with long-term, convenient, high-quality, standardized and reliable services; Have good radio and television business operation, publicity and promotion capabilities.
Local service agencies are mainly responsible for: managing the sales and installation services of local receiving facilities; Cooperate with the administrative department of radio and television to divide the service area of direct broadcast satellite, and cooperate with the competent department to identify and clean up the illegal satellite receiving facilities in the service area; Report the information of wireless mobile communication base stations in the service area to the management center.
In the service area, establish and improve the joining point and service team of receiving facilities according to the principle of fairness and justice, report to the management center for filing, and conduct installation service training; Regularly book encryption cards from the management center, establish encryption card files, and sell them to franchisees according to their sales plans; According to the requirements of local tasks, purchase acquisition instruments from the management center and manage them; Supervise and manage the service quality of franchisees and service teams, and organize the promotion of direct broadcast satellite services.
Direct broadcast satellite receiving facilities are equipment for receiving direct broadcast satellite public service signals, including set-top boxes, antennas, tuners, encryption cards, feeder cables and conventional installation auxiliary materials. The receiving equipment and its installation services shall be purchased by the end users themselves.
Direct broadcast satellite set-top box is a conversion device that converts satellite signals into video and audio signals. It is suitable for receiving TV sets and can be divided into single-mode set-top boxes and dual-mode set-top boxes. A single-mode set-top box refers to a set-top box that can only receive live satellite radio and television signals, and a dual-mode set-top box refers to a set-top box that can receive both live satellite radio and television signals and digital radio and television signals transmitted on the ground. After installing the dual-mode set-top box, you can watch multiple sets of local TV programs from the terrestrial video broadcast.
In order to effectively manage each set-top box and each set of programs, satellite live programs are broadcast in an encrypted way. Only by using the encryption card can we receive the authorization of the satellite live broadcast front end and watch the satellite live broadcast program normally. When the receiving device is installed and inserted into the set-top box, the encryption card is distributed. After successful installation, there is no need to update the encryption card.
The direct broadcast satellite set-top box has built-in positioning module, which has positioning function and cannot be used outside the direct broadcast satellite service area. Some types of set-top boxes have telephone interfaces, which can provide telephone services by using the wireless two-way communication function provided by the positioning module. Telephone service needs to be paid to the local mobile phone operator.
The electromagnetic signal received by the antenna is sent to the receiver. An ideal receiver suppresses all unnecessary noise, including other signals, and does not add any noise or interference to the desired signal. No matter the form or format of the signal, it can be converted into the characteristics required by the detection circuit of the signal processor, and then sent to the intelligent user interface.
The so-called superheterodyne receiver is to mix or down-convert the received RF signal with a local oscillator signal of a certain frequency, and then output an intermediate frequency modulation signal with a lower frequency. The frequency of the IF signal is a fixed frequency difference between the local oscillator signal and the received signal. The demodulation of the final signal is to filter and amplify the intermediate frequency signal, and then the demodulator completes it at the intermediate frequency.
In the direct conversion receiver, its basic principle is the same as that of the heterodyne receiver, but the difference is that the local oscillator frequency involved in mixing is not arbitrarily given, but equal to the carrier frequency, so the intermediate frequency is 0, so there is no image frequency and image frequency interference. This scheme is usually called zero intermediate frequency scheme.
The mirror frequency filter is omitted in the RF part of the scheme, and the intermediate frequency filter becomes a low-pass filter, which simplifies the composition of the system, reduces the difficulty of design and implementation, and saves the cost. However, the direct conversion receiver has obvious shortcomings, such as the same local oscillator frequency and carrier frequency, which is easy to cause local oscillator leakage; There is DC deviation, which has a serious impact on the subsequent circuits; It can only be used to demodulate AM signals, but not FM and PM signals. The stability of local oscillator is required, so it is mostly used only in low frequency band.
