In digital satellite TV, PID code is an identification code of a grouping or data packet in the data stream transmitted by satellite TV. It is divided into video PID code, audio PID code, and clock synchronization PID code (namely, PCR PID code). A few years ago, some friends used the method of adding a PID code to receive live TV programs in Taiwan. At the time, the PID code became a hot topic in the TV fever circle. The digital machine with the function of adding a PID code was also speculated by the market. Nowadays, there is no commercial PID code for conditional reception, and most of the digital machines produced have the function of adding and modifying PID codes. The current development of the satellite TV industry has increased the number of video channels and the screen has become more and more colorful. However, some TV programs that do not want others to watch, especially those programs that are not suitable for children, cannot be controlled. Using the PID code method can limit this Ratings of similar programs.
1. Hide TV programs. In general digital satellite receivers, TV programs and broadcast programs are stored separately, that is, TV programs are stored in TV program channels, and broadcast programs are stored in broadcast program channels. The TV / broadcast switching key enables the receiver to be in TV programs and broadcast programs. Switch between time, it is very convenient to watch and listen to the program. Therefore, you can hide the TV programs that you do not want others to watch to the broadcast program channel. The operation method is: first press the TV / Broadcast key to enter the broadcast program channel, enter the "Setup Program" menu, open the "Add Program" submenu, and you will know Add the video PID code, audio PID code, and PCR PID code, and then press the TV / Broadcast switch key to return to the TV program channel and delete the channel. In this way, this channel is hidden into the broadcast program channel, and this channel cannot be found in the TV program channel. When watching the channel, press the TV / Broadcast switch button to enter the broadcast program channel to watch. You can also directly enter the reception parameters to search again, and the channel reappears on the TV program channel.
2. Modify the PID code. Enter the "Edit Program" menu, select a TV program channel that is inconvenient for others to watch, change the video PID code or the PCR PID code slightly, and the black screen will be displayed when the channel is viewed after confirmation and saving. You can restore the PID code when you want to watch, or you can enter the receiving parameters to search again. After re-searching, the channel is listed at the end of the TV program list as a newly added channel, and the channel with the original modified PID code still displays a black screen and is arranged in the program list.
Small Solar Panel
Our Sunket also has a multi-busbar small module production line specializing in the production of small panels for more than ten years.
From 158.75mm 5BB to 182mm 10BB to 210mm 12BB, from 10W to 400W has been fully covered. In addition, our certificates are complete.
Smaller solar panels can be used in many different ways: as a phone charger, for RVs and during camping trips, and for small off-grid solar projects. If you're looking to save money by offsetting your home energy use with a Solar Power System, small panels likely won't get the job done.
Solar panels may be worth it for smaller roofs if you install a system that uses more efficient solar panels, such as monocrystalline solar panels, as they generate more power using less space. The ideal roof slope for solar panels is between 30 degrees and 45 degrees.
