Data processing method based on DVB, DVB device, and readable storage medium

A data processing method based on DVB, applied to a mobile terminal, comprising steps:

• scanning a quick-response (QR) code of a DVB device to establish a connection between the DVB device and the mobile terminal;
• receiving and displaying a first program list, and monitoring an operation of a user;
• receiving operation information sent by the mobile terminal;
• if the operation of the user is a first on-demand operation, sending the first program data request information corresponding to the first on-demand operation to the DVB device, receiving and displaying a first data stream sent by the DVB device, wherein the first data stream is obtained by receiving, filtering, descrambling, and decrypting satellite signals by the DVB device;
• and
• if the operation of the use is a search operation, sending a search request to the DVB device, receiving a matching result and a second program list from the DVB device;
• if a second on-demand operation is performed, sending second on-demand operation information to the DVB device;
• receiving and displaying a second data stream sent by the DVB device;
• wherein the DVB device receives data stream information corresponding to a program corresponding to the second on-demand operation information sent by a serve;
• and the DVB device directly decrypts the data stream information to obtain the second data stream;
• wherein the second program list comprises a first program sublist and a second program sublist;
• the first program sublist is a public program list:
• the second program sublist is a restricted program sublist;
• wherein after the step of sending the search request to the DVB device, receiving the matching result and the second program list from the DVB device;
• if the second on-demand operation is performed, sending the second on-demand operation information to the DVB device, the data processing method further comprises:
• if the second on-demand operation is associated with the first program sublist, sending second program data request information corresponding to the second on-demand operation to the DVB device;
• and
• if the second on-demand operation is associated with the second program sublist, sending information of a login account of the mobile terminal and the second program data request information corresponding to the second on-demand operation to the DVB device.
