Embodiment 1

[0052] figure 1 It is a configuration diagram of a terminal system of a TV program receiving device providing the service of the present invention. A STB as a television program receiving device includes a signal receiver 100 , a data analyzer 200 , an image processing module 300 , a channel selection receiver 400 , a controller 500 , a storage area 600 , a conditional access module 700 , and a memory 800 . Below, refer to figure 1 Describes the functions of the components of the set-top box.

[0053] The signal receiver 100 includes a tuner and a demultiplexer for receiving and demodulating high-frequency signals, regenerating TS, and separating various types of data according to different PIDs.

[0054] The data analyzer 200 is used to receive the information in the TS, and extract useful information about the present invention, such as the PID of the TV program received by the tuner.

[0055] The image processing module 300 includes a decoder, and for a set-top box, also...

Embodiment 2

[0110] Embodiment 2 In the 4 parts of the process that the TV program receiving device of the present invention receives and plays TV programs, there are the same Part 1, Part 3, and Part 4 as in Embodiment 1, and only the automatic The part of storing and updating the advertising content is different. In Embodiment 2, only the corresponding advertising content of the channel that the user has no right to watch is saved. The following reference Figure 11 Explain its logical process.

[0111] When the user starts the system, the program list is obtained, and the conditional access module 700 returns user information at the same time, and the controller 500 obtains the information corresponding to each channel whether the user has the right to watch, and at the same time, the data analyzer 200 returns the information of each TS The corresponding ad content information in .

[0112] After the channel selection receiver 400 user selects a program, in step L201, the controller 50...

Embodiment 3

[0115] Embodiment 3 In the 4 parts of the process that the TV program receiving device of the present invention receives and plays TV programs, there are the same part 1, part 3, and part 4 as in embodiment 1, but in the set-top box of part 2 It is different from Embodiment 1 in automatically storing and updating advertisement content. The difference is the allocation method of the user area in the memory area. In Embodiment 3, a certain storage space is allocated to each operator.

[0116] During operation, an operator generally uses multiple TSs to transmit the operator's programs. When the user turns on the phone, the data analyzer 200 obtains the corresponding relationship between the TS and the operator from the NIT, and sends the information to the controller 500 . The controller 500 allocates storage space with a fixed length to each operator.

[0117] When the TS of the channel selected by the user contains the advertisement content transmitted by a certain operator...

Abstract

The invention provides a television program receiver of condition receiving system and a method for receiving and playing television program, for providing information display service, as informationtransmission, receiving and displaying. When user selects the television program not opened to the user, the receiver automatically play a television program pre-stored in the receiver, provided by operator, as advertisement or program instruction. The service provided by the invention comprises that (1), operator selects advertisement or program instruction to play, (2), the receiver receives advertisement or program instruction to analyze the storage demand, (3), the receiver judges if user has priority to watch selected program, when user has no priority, the receiver triggers to play the advertisement or program instruction not interfered.

Description

technical field [0001] The invention relates to a program receiving device in a conditional receiving system and a method for receiving and playing TV programs. The present invention particularly relates to the method for receiving and playing television programs of the television program receiving equipment utilizing the existing digital television broadcasting system and the television program receiving equipment, which utilizes SI (Service Information), PSI (Program Specific Information) in the MPEG2 standard ) to transmit advertisement or program preview information, receive, store and play the advertisement or program preview information broadcast by operators. Background technique [0002] Pay TV is a feature of digital TV, and the conditional access system is a necessary means to realize pay TV. The conditional access system protects the interests of operators by preventing unauthorized access to streaming media content. The conditional access system has been widely ...
