Embodiment Construction

[0020] see figure 1 As shown, the method for realizing the replacement of the start-up screen of the set-top box by the external storage medium of the present invention comprises the following steps:

[0021] Step 10, apply for storage space for conversion work;

[0022] Step 20, according to the type of the file selected by the user in the external storage medium such as U disk or sd card, call the corresponding decoding module to decode, and convert the decoded data into the pure picture data of the format of 1555, RGB respectively use 5 bits to indicate, and 1 bit to indicate whether it is transparent;

[0023] Step 30, scaling the pure picture data in 1555 format to standard definition resolution, and corresponding conversion for the video system of the system, wherein PAL is 720*576, and NTSC is 720*480;

[0024] Step 40, delivering the scaled pure picture data to the buffer area of ​​the OSD, and sending it to the screen through the hardware 2D acceleration engine;

Abstract

The invention provides a method for realizing startup picture change of a set top box through an external memory medium. The method comprises the following steps: applying for a storage space; calling a corresponding decode module for decoding according to the type of a user selected document in the external memory medium, and converting the document to pure picture data in 1555 form; scaling the data into standard definition resolution; transmitting the data to an OSD buffer zone, and transmitting the data to a screen through a hardware 2D cache; calling video output drive of the set top box to scrap video of the screen; reading the acquired corresponding video frame data in the storage space for updating in next startup; searching the startup picture data after the set top box is restarted, transmitting the data to a video buffer; setting the video output drive of the set top box; and displaying the data of the video buffer zone on the screen to complete startup picture realization and other steps. Therefore, the method realizes the function that a user can customize a picture required to be displayed through the external memory medium to update the startup picture.

Description

【Technical field】 [0001] The invention relates to a set-top box, in particular to a method for realizing replacement of the start-up screen of the set-top box through an external storage medium. 【Background technique】 [0002] At present, the start-up screen of the traditional digital TV set-top box is single and fixed, which is generally displayed as the start-up screen logo of the broadcasting TV operator or some other fixed screens, which cannot be changed by the user. As the user's personalized needs become more and more intense, it is necessary to reflect some special personality screens on the boot screen. At the same time, it is also required that each boot can be different, and the content to be displayed can be independently modified by oneself. However, the existing set-top box can only provide a new boot screen logo if the operator actively upgrades the program. And the existing method that the broadcasting and television operator provides an upgrade program to u...
