Problems solved by technology

However, the user does not necessarily purchase all the programs. In this way, there are both purchased programs and unpurchased programs in the generated program list.
[0006] In the process of realizing the present invention, the inventor found that the prior art has the following defects: since there are both purchased programs and unpurchased programs in the generated program list, when the user switches channels, for unpurchased programs, The program will prompt the words "unpurchased" or "unauthorized" on the screen, so that the user cannot see the purchased program in time, especially when there are a large number of unpurchased programs, the user will spend a lot of time to switch to It is not convenient for users to use the purchased programs and find their favorite programs, nor can it reflect the user-friendly design of digital TV, and also affect the mood of users watching TV

Embodiment 1

[0038] An embodiment of the present invention provides a method for generating program information, such as figure 1 As shown, the method includes:

[0039] Step 101, determine whether the programs in the generated program list have been authorized, the program list includes the channel ID, the program ID of the program corresponding to the channel ID, and the description information of the program; or the program list includes the channel ID, corresponding to the channel ID The program ID of the program, the authorization ID corresponding to the program ID, and the description information of the program.

[0040] Step 102: Set the corresponding authorized play flags on the authorized programs in the program list to generate a program list including the play flags, so that when the terminal device receives an instruction to display program information transmitted by the user through the remote control device, Unauthorized program information with no playback flag set will not...

Embodiment 2

[0063] An embodiment of the present invention provides a method for generating program information, which will be described below by taking the front end as an example to determine whether a program in a program list is authorized by issuing an authorization and program correspondence table through service information.

[0064] Such as figure 2 As shown, the method includes:

[0065] On the front end:

[0066] Step 201, the front end of the conditional access system generates an authorization and program correspondence table, the correspondence table includes the program identification corresponding to the program, and the authorization identification corresponding to the program identification;

[0067] In this embodiment, the authorization-program correspondence table indicates the program identifiers and corresponding authorization identifiers of all programs sent by the front end, as shown in Table 3.

[0068] In this embodiment, the generated correspondence table may b...

Embodiment 3

[0088] An embodiment of the present invention provides a method for generating program information, which is described below by taking a terminal device decrypting a received ECM data packet to determine whether a program in a program list is authorized as an example.

[0089] Such as Figure 4 As shown, the method includes:

[0090] On the front end:

[0091] Step 401, the SI server at the front end of the conditional access system generates service information;

[0092] Wherein, the service information may include existing program identification (ID) (that is, the serial number of each program), transmission content, arrangement and time table of broadcast data, and other data.

[0093]Step 402, the SI server transmits the service information to the multiplexer, and the entitlement control information ECM generated by the Entitlement Control Message Generator (ECMG: Entitlement Control Message Generator) and the Entitlement Management Information Generator (EMMG: Entitleme...

Abstract

The invention provides a program information generating method and terminal device. The method comprises the following steps: the terminal device determines whether generated programs in a first program list are authorized, wherein the first program list comprises channel identifications, program identifications corresponding the channel identifications and descriptive information of the programs; and corresponding authorized play identifications are set for authorized programs in the first program list to generate a second program list comprising play identifications, so that unauthorized program information without play identifications is not displayed when the terminal device receives a program information display command transmitted by a user through a remote-control device. The user can only switch channels among the authorized programs when switching channels to watch TV programs, thus the time for the user to search for the programs is saved, and the mode of watching programs at the terminal is more reasonable and humanized.

Description

technical field [0001] The invention relates to digital television technology, in particular to a method for generating program information and terminal equipment thereof. Background technique [0002] At present, digital TV has entered a stage of rapid development, and services related to digital TV will also increase substantially. [0003] The program operator organizes all the programs at the front end of the conditional access system, and uses service information (SI: Service Information) to describe all programs in the entire system. The service information SI may include: program identification (ID), transmission content, and broadcast data flow Data such as arrangement and timetable; among them, the program identification ID is the serial number of each program. Then, the service information SI is multiplexed into a transport stream (TS: Transport Stream) and broadcast to all users; wherein, the service information SI is also the guide information of the code stream...
