Specifically, after the foregoing step S105, the first set top box may determine, by using a predetermined rule, whether the program information list includes program information of all television channels of the second set top box. In a specific implementation, the predetermined rule may include: when the same segment repeatedly appears in the program information list, the preset set number of program information having different program names in the segment, the first set top box determines that the program information list includes Program information for all TV channels of the second set top box. For example, referring to Table 1, the same segment is repeated in the program information list shown in Table 1. There are 3 different programs in the segment, and the program information list shown in the first set top box determination table 1 includes the second set top box. Program information for all TV channels.
