Embodiment Construction

[0031] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0032] Such as figure 1 Shown is the work flowchart of the embodiment of the present invention;

[0033] Step S110, when the set-top box is powered on, the set-top box judges whether the boot program has been copied to the double rate (Double Date Rate, DDR) memory, whether there is a normal boot program in the DDR memory, if not, then execute step S120, otherwise execute step S121;

[0034] Step S120, the set-top box decompresses and copies the boot program saved in the flash to the DDR memory, and executes step S121;

[0035] Step S121, start the boot program from the DDR memory, and execute step S130;

[0036] In step S130, after the boot program in the DDR memory is started, each device is initialized, the environment before the power failure is restored, and the program runs normally to provide various services for the user.

Abstract

The invention relates to the related technical field of a set top box (STB), in particular relating to an STB starting method and system. The method comprises the following steps: performing start-up detection on a volatile memory after the STB is powered on; if a start-up program is stored in the volatile memory, executing the start-up program in the volatile memory; otherwise, copying the start-up program from a non-volatile memory to the volatile memory, and then executing the start-up program in the volatile memory; charging an internal rechargeable power supply by virtue of an external power supply after the STB is powered on; and supplying power to the volatile memory by virtue of the internal rechargeable power supply after the STB is in power failure. According to the technical scheme provided by the invention, the rapid start-up of the STB is realized so that the STB subscriber can watch the program and enjoy various functions of the digital TV (television) after ultra-short wait time.

Description

technical field [0001] The invention relates to the technical field related to set-top boxes, in particular to a method for starting a set-top box. Background technique [0002] Flash memory (flash) is a non-volatile memory. After the power is turned off, the data can still be kept in the memory, while the memory, that is, the random access memory, is a volatile memory. After the power is turned off, the data cannot be saved in the memory. . But the read and write speed of memory is much faster than that of flash. Therefore, after the current set-top box is powered on, the program is copied and decompressed from the flash to the memory, and then the program is started from the memory. The process of copying and decompressing the program from the flash to the internal memory takes a lot of time, which makes the start of the set-top box slow and makes the user wait for a long time. Contents of the invention [0003] The first object of the present invention is to provide ...
