What are the reasons why the set-top box is not authorized?

Possible reasons why the set-top box is not authorized:

1. The viewing fee has just expired, and all encrypted programs will prompt the message "This program is not authorized".

2. Some programs are pay TV programs (such as: securities information, CHC movies, etc.). These programs are not included in the paid viewing fee and need to be purchased separately to watch.

3. For the fees just paid, the front-end has not had time to authorize the user, or the user's set-top box is turned off during the authorization process and cannot receive the authorization information.

Solution: Bring the set-top box and card to the Cable Radio and Television Service Center and explain which programs cannot be watched. The staff will ask you to pay the fee and will successfully authorize the set-top box. You can watch TV programs normally after returning home.

The working principle of the digital TV set-top box display program:

The modules of the set-top box work together in high-speed Internet access.

The user first requests the url by sending a command. In a transaction using the PPP point-to-point protocol, the command ultimately reaches the internet service provider's modem sharing rack. Then through the method of dynamic allocation, the user obtains the IP address used in the transaction and sends the request to the Internet.

When Internet content is discovered, it is sent to the Internet Service Provider (ISP), and then the ISP's router is responsible for sending it to the cable television network and finally back to the user's set-top box. In cable TV set-top boxes, information content is intercepted. The set-top box completes the gateway task between the TV and the cable network. Its task is to manage the communication flow of IP.

Once the IP packet reaches the set-top box, it can control the user's access to the network. Once the IP packet reaches the set-top box, it separates the video signal from the packet, decodes the data in the packet, and sends it to the browser for display on the TV.
