Embodiment Construction

[0044] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described in detail with reference to the accompanying drawings.

[0045] figure 1 It is a schematic diagram of storage in the memory of the program run by the method for booting and starting the set-top box in the prior art. Such as figure 1As shown, in the prior art set-top box boot method, by running the boot program 110 to call the application program 120 to start the set-top box, the main chip of the set-top box first loads the boot program 110 to the internal memory by the set-top box flash memory, and through the boot program 110 to the hardware of the set-top box Parameters are configured, and the application program 120 is loaded into the memory, and then the application program 120 is run based on the hardware parameters configured by the boot program 110 . The boot program...

Abstract

The invention discloses a method and a device for guiding and starting a set top box. The method comprises the steps that a first hardware parameter is fixedly preset in a first guide program according to an upward or downward compatibility characteristic of set top box hardware parameters; CA (computer associate) digital signature is conducted on the first guide program containing the first hardware parameter; initial configuration is conducted on the set top box hardware parameters by the decrypted first guide program; a second guide program and an application program are loaded to a memory; reconfiguration is conducted on the hardware parameters by the second guide program according to an actual use requirement; and the application program is run. According to the method and the device, the second guide program is additionally set between the first guide program and the application program, so that the set top box hardware parameters for different application services can share and use the same first guide program signature file; repeated signature due to change of hardware parameter configuration is avoided; the high security of the set top box is ensured; a research and development period is shortened; and the research and development cost is lowered.

Description

technical field [0001] The present invention relates to the technical field of set-top boxes, and more specifically, to a method and device for guiding and starting a set-top box. Background technique [0002] When the set-top box starts to run, the main chip of the set-top box first runs the boot program, configures the hardware parameters of the set-top box through the boot program, and loads the application code stored in the flash memory of the set-top box, and then jumps to the application code, according to the settings set by the boot program hardware parameters to run the application. The hardware parameters set by the boot program mainly include memory capacity and clock frequency, etc. For different set-top box applications, application software has different requirements for memory, so the hardware parameters set in the boot program are also different. [0003] In order to control the viewing rights of pay TV and protect the information security of the set-top bo...
