- step 203 the user set top box performs program hiding according to the sub EPG, and can hide all programs not included in the sub EPG, and can also hide all programs included in the sub EPG.
- program hiding can be implemented for group users in each sub-front-end management scope.
- each sub-front end can separately manage user set-top boxes in different regions, and the sub-front code can be the area code of the area managed by the sub-front end, so that different programs can be hidden for users in different regions. That is, different program viewing restrictions can be implemented in different regions, for example, different viewing restrictions are implemented in urban and suburban areas.
- the correspondence between the area code and the sub-EPG can be realized by the feature value in the total EPG, that is, two lists are established in the total EPG. The first list stores a one-to-one correspondence between each area code and each different feature value.
- the second list stores each feature value and a sub-EPG corresponding to each feature value, and each sub-EPG includes its All program information that can be searched for in the corresponding area, that is, a list of programs that can be viewed. In this way, when it is necessary to adjust the program that can be viewed in a certain area, it is only necessary to modify or replace the sub EPG corresponding to the feature value corresponding to the area code of the area in the total EPG.
- the split front end can be implemented by modifying the area code of the total front end in the total EPG to its own area code, and then sending the total EPG to the user set top box in the area.
- the own area code is sent to the user's set top box in the area.
- the user set-top box After receiving the total EPG, the user set-top box first knows the area code of the area where the area is located from the total EPG, and then finds the area code of the area where the area is located from the first list containing the correspondence between the area code and the feature value. Corresponding feature values, and according to the feature values, find corresponding sub-EPGs from the second list of the sub-EPGs corresponding to the respective feature values and corresponding to the respective feature values, and then perform program hiding according to the sub-EPG.
- the area code may be a flag value (N_ID) of the network information table NIT
- the feature value may be a flag value (B_ID) of the group information table BAT.
- the TV programs issued by Shenzhen City include: "Phoenix Satellite TV", “National Geography”, etc., and now Radio and Television does not want users in Longgang District to watch "Phoenix Satellite TV” and "National Geography” are two programs, users in other regions can watch these two programs.
- the N_ID of the total front end of the city network is 1, and the N_ID of Longgang District is 5.
- N_ID 5
- B_ID 0x7011
- This table describes the service address Servicejd of all programs that can be searched in Longgang District, but does not include "Phoenix Satellite TV" and "National Geographic”.

- Step 302 Each sub-front end filters out all sub-Es that do not correspond to its own code from the received total EPG.
- the PG sends the filtered total EPG to the user's set-top box within its management scope.
- the split front end filters out all sub EPGs that do not correspond to its own code from the total EPG, and only retains the sub EPG corresponding to its own code in the total EPG, and deletes all other sub EPGs.
- Step 303 the user set top box searches for the program according to the received total EPG.
- each of the sub-front ends can separately manage user set-top boxes in different regions, and the front-end code can be the area code of the area managed by the sub-front end, and thus can be implemented for users in different regions. Different programs are hidden. And in the embodiment shown in FIG. 3, the filtering function of the front end is utilized, from The source realizes program hiding, which guarantees viewing restrictions. In addition, in the implementation shown in FIG. 3, as in the solution described in Embodiment 2, in order to implement flexible allocation of the sub-EPG at the front end, the eigenvalue can be used to implement the area code and the sub-EPG in the total EPG. The correspondence is not repeated here.

- Step 403 The user set top box finds the sub E corresponding to the acquired feature value from the received total EPG.
- program hiding can be implemented for a specific unit or even an individual. For example, government agencies, hotels, etc.
- a smart card containing a feature value can be assigned to a user, and the user set top box reads the feature value from the smart card containing the feature value.
- Shenzhen Broadcasting and Television does not want User A to receive "Phoenix Satellite TV".
- User A's set-top box first reads the feature value 0x7011 from the smart card and saves it, then finds the BAT table corresponding to the feature value 0x7011 from the received EPG, and searches for the program according to the BAT table, where the BAT table is not described. The programs are filtered out. In this way, User A will not search for "Phoenix Satellite TV".
- the front end of Longgang District receives the total EPG delivered from the total front end of the city network. After that, directly filter out the sub EPG that does not belong to Longgang District, and then filter it.
- the total EPG is issued to the user's set-top box in the area. In this way, a smart card that has a feature value that does not belong to Longgang District cannot be used in Longgang District.
