Abstract
The invention relates to an embedded set-top box, and simultaneously relates to a startup picture display technique. The invention provides a method for rapidly displaying graphical signs of IP set-top boxes and guaranteeing system stability. The method for displaying graphical signs of IP set-top boxes comprises the following steps of adding a special partition for storing the graphical signs to a FLASH partition table guiding a loading program and a FLASH partition table of an operating-system kernel respectively, and guiding the loading program to analyze and display a graphical sign after an IP set-top box is powered up. The method is applicable to the rapid stable display of the startup pictures of various embedded devices.
Description
Technical field
The present invention relates to embedded set top box, relate to startup picture simultaneously.
Background technology
Development along with the IPTV business, IP set-top box (IP-STB) market competition is constantly aggravated, a distinct characteristics, recognize easily and memory, implication are deep, the vendor graphical sign (logo) of beautiful design, can allow product in the same trade, highlight, and the enterprise operation direction, accept the variation of colony, can make the logo sign produce necessity of upgrading.
IP terminal device logo such as IPTV design also should meet the following requirements except the most basic will having the good display effect:
(1) in the shortest time, shows start logo picture, give user's first visual experience;
(2) change to logo can not influence system file;
(3) under the subscriber household environment for use, be convenient to upgrade logo.
Summary of the invention
Technical matters to be solved by this invention is a kind of quick demonstration to be provided, to be convenient to upgrade, and guarantee the pattern sign display method of the IP set-top box of system stability.
The present invention solves the problems of the technologies described above the technical scheme that is adopted to be, the pattern sign display method of IP set-top box, in the MTD of the FLASH of bootstrap loader partition table and operating system nucleus equipment subregion, increase a subregion that is exclusively used in the graphics sign, after the IP set-top box powered on, the bootstrap loader parsing also showed described logotype.
After described IP set-top box powered on, bootstrap loader was resolved and is shown that described logotype comprises step: a, bootstrap loader initiating hardware; The picture file whether prescribed form is arranged in the subregion of b, bootstrap loader detection of stored logotype; In this way, enter step c; As not, enter steps d; C, bootstrap loader are resolved and are shown described logotype, enter steps d; D, the kernel that starts the operating system, loading root file system start and use master routine.
Realize the parsing and the demonstration of logotype in first stage bootstrap loader of system start-up, realized in the shortest time, showing the start logotype, while bootstrap loader file and logotype file separate processes, upgrade logo and can not influence bootstrap loader and kernel system file, guaranteed system stability.
Further, after using master routine and starting, when detecting upgrade server the logotype that needs to upgrade being arranged, use master routine and download the logotype that needs to upgrade and also store the subregion that is used for the graphics sign into.The application program operation phase utilizes the HTTP procotol to download logotype, utilizes system tool that download pictures is written to the assigned address of flash memory device, has realized the immediate updating of logotype.
The invention has the beneficial effects as follows, guaranteeing under the system stability, show the unmanned down logotype of upgrading automatically of start logotype and subscriber household environment in the shortest time.

Embodiment
The picture that the bootstrap loader of IP-STB (BootLoader) shows can be supported multiple form, and the present invention is that example describes with 24 bitmaps (BMP) format picture, and memory device adopts NANDFLASH.
At first be that the FLASH partition table that will revise IP-STB (comprises the FLASH partition table of BootLoader and the MTD equipment of operating system nucleus kernel (memory techniques equipment) partition table, and the MTD equipment partition table (MTD1 of kernel kernel, 2,3,4) must be consistent with the FLASH partition table of BootLoader), increase a new subregion and store the logo.bmp picture specially.Promptly at original subregion: root file system subregion flash.rootfs, kernel kernel subregion flash.kernel, MAC Address subregion flash.mac is on the BootLoader subregion flash.bootloader basis, increase a logo picture subregion flash.logo, as shown in Figure 1.Like this can be easily under the BootLoader order line the logo.bmp picture flash.logo subregion that writes direct.
The product course of work is as shown in Figure 2:
1, system powers on;
2, BootLoader initiating hardware;
Whether 3, BootLoader detects the flash.logo subregion the bmp format picture, in this way, then resolves picture, shows resolving good image data then, enters next step; As not, directly enter next step;
4, Kernel starts, loads root file system;
5, start the application master routine;
6, detect upgrade server,, and be written in the flash.logo subregion, realize that network upgrades logo by http protocol network download logo picture.
Step 3, displaying principle are the demonstration of image data based on framebuffer.Detailed process is:
3.1, the framebuffer initialization;
3.2, open FLASH equipment subregion flash.logo, copy the assigned address (BmpMemory) of this subregion content to system's memory ram;
3.3, resolve memory address BmpMemory place data, comprise four parts:
A, bitmap file head
B, message bit pattern head
C, color table
D, image data array
Resolve a, b, c obtain picture format, size, width, highly, the information such as figure place of each pixel.
D image 24 bit data value are converted to rgb value, according to pixel of 2 bytes, write the image rgb value then, realize that image shows to framebuffer.
Step 6, realize that network upgrades logo and need possess following condition:
(1) WEB upgrade server
(2) MTD instrument (flash_eraseall, nandwrite)
MTD tool making process is write flash_eraseall.c, nandwrite.c, uses the cross compile instrument, downloads to the IP-STB root file system after the compiling.
Upgrading the logo detailed process is:
6.1 build the network WEB upgrade server, the picture logo.bmp that needs are upgraded is put under the server respective directories (update), waits for client downloads;
6.2IP-STB as client, use master routine and start whether the back system detects automatically has file to be called logo.bmp under the upgrade server update catalogue file,, download logo.bmp to IP-STB system memory ram by http protocol if having;
6.3 utilize MTD instrument flash_eraseall to wipe mtd4 subregion (corresponding BootLoader partition table flash.logo), nandwrite writes logo.bmp to mtd4 equipment, restarting systems.
Claims (3)
- The pattern sign display method of [claim 1] IP set-top box, it is characterized in that, in the MTD of the FLASH of bootstrap loader partition table and operating system nucleus equipment partition table, increase a subregion that is exclusively used in the graphics sign, after the IP set-top box powered on, the bootstrap loader parsing also showed described logotype.
