Embodiment 1

[0032] figure 1 It shows the implementation flow of the program monitoring method provided by Embodiment 1 of the present invention. A selected program is used as the first program, and other programs except the first program are used as the second program. The first program side is taken as an example below For explanation, the details are as follows:

[0033] In step S101, the first program sends heartbeat information to the second program, and at the same time receives the heartbeat information sent by the second program.

[0034] In the embodiment of the present invention, a single program in a digital TV receiving terminal is divided into at least two programs according to functions.

[0035] For example, in this embodiment, a single program in a digital TV receiving terminal is divided into programs such as electronic program guide (Electronic Program Guide, EPG), CA, and personal video recorder (personal video recoder, PVR) according to functions.

[0036] Among them,...

Embodiment 2

[0052] image 3 A specific structural block diagram of the program monitoring device provided by Embodiment 2 of the present invention is shown. For convenience of description, only parts related to the embodiment of the present invention are shown. The program monitoring device 3 includes: a heartbeat information transmission unit 31 , a monitoring unit 32 and a monitored unit 33 .

[0053] Wherein, the heartbeat information transmission unit 31 is configured to send heartbeat information to the second program, and simultaneously receive the heartbeat information sent by the second program;

[0054] The monitoring unit 32 is configured to perform exception processing if the heartbeat information sent by the second program is not received within the preset receiving time;

[0055] The monitored unit 33 is configured to execute exception handling by the second program if the second program does not receive the heartbeat information sent by the first program within a preset rec...

Abstract

The present invention is applicable to the field of network broadcasting and television, and provides a program monitoring method, device and digital TV receiving terminal. The method includes: the first program sends heartbeat information to the second program, and simultaneously receives the heartbeat information sent by the second program; If the heartbeat information sent by the second program is not received within the preset receiving time, the first program performs exception processing; if the second program does not receive the heartbeat information sent by the first program within the preset receiving time, then Exception handling is performed by the second program. In the present invention, each program of the digital TV receiving terminal has the function of monitoring and being monitored. If one of the programs is abnormal or attacked, it will be monitored by other programs, and then other programs will perform abnormal processing, which can prevent sensitive data from being Theft ensures the system security of the digital TV receiving terminal.

Description

technical field [0001] The invention belongs to the field of network broadcasting and television, and in particular relates to a program monitoring method, device and digital television receiving terminal. Background technique [0002] With the advancement of science and technology, people's demand for smart set-top boxes continues to increase, and multi-tasking operating systems are also used in current smart set-top boxes. [0003] However, some multitasking operating systems are open source, such as Linux systems, which have many security risks. At the same time, more and more attention has been paid to the security of conditional access (CA) data of the smart set-top box. [0004] The software system of the current smart set-top box is composed of a single application program. When the only application program is abnormal or is attacked by hackers, no self-protection measures are taken. Contents of the invention [0005] The embodiment of the present invention provid...
