Version file carries out differential comparison, generates corresponding first script file and first differential file.
S202：Each institute is generated according to first script file, first differential file and first signed data
State the corresponding upgrade file of set-top box current version.
When it is implemented, assuming that root file system uses squashfs, there are 01,02,03 three machine tops for root file system
Box current version uniformly needs to be upgraded to 04 version (i.e. the first upgraded version of set-top box is 04 version), wherein set-top box first
Upgraded version includes：Multiple update version documents and a signed data, set-top box current version include：Multiple version files with
An and signed data.
The specific implementation procedures of step S201 are as follows：
1, each set-top box current version is all copied under patch_make/rootfs/image, name is respectively:
image_rootfs_release_ver_01.bin,
image_rootfs_release_ver_02.bin,
image_rootfs_release_ver_03.bin,
image_rootfs_release_ver_04.bin
2, each set-top box current version is decompressed to patch_make/rootfs/mount/rootfs_ver_xxx catalogues, life
It enables as follows：
unsquashfs-d patch_make/rootfs/mount/rootfs_ver_01
patch_make/rootfs/image/image_rootfs_release_ver_01.bin
Each set-top box current version is mounted to corresponding catalogue by the mount modes for being originally here, but is all in public affairs
It is developed on server altogether, other users do not have root authority, so being modified as the mode of anti-decompression.
3, it is that 04 version does difference (at the ends linux with the first upgraded version of set-top box respectively by each set-top box current version
Diff) compare.It is the liter in 04 version by version file and the first upgraded version of set-top box in each set-top box current version
Grade version file is compared one by one, obtains upgrade file corresponding with the version file of the set-top box current version.Wherein, it rises
Grade file include：First script file, the first differential file and the first signed data.It is first poor that first script file can call
Different article part executes the operations such as deletion, increase, modification to the first differential file, and invention is not limited thereto.First signed data is
The signed data generated in response to the generation of the first script file and the first differential file, is disposed on the head and the tail position of upgrade file
The data set.
The specific implementation procedures of step S202 are as follows：The current version of each set-top box is generated under patch_make/rootfs/patch
This corresponding patch files, that is, each upgrade file is as follows：
After carrying out differential comparison with image_rootfs_release_ver_01.bin, acquisition upgrade file is rootfs_
ver_01_patch。
After carrying out differential comparison with image_rootfs_release_ver_02.bin, obtaining update version document is
rootfs_ver_02_patch。
After carrying out differential comparison with image_rootfs_release_ver_03.bin, obtaining update version document is
rootfs_ver_03_patch。
And each set-top box current version is needed into the file copied or catalogue, copy patch_make/rootfs/ to
Update/file catalogues.
In step s 102, difference is carried out to each set-top box to be upgraded in step S101 and the first upgraded version of set-top box
The first script file obtained more afterwards takes union to generate second script file.To each set-top box and set-top box to be upgraded
The first differential file that first upgraded version obtained after differential comparison takes union to generate second differential file.It will generate
The second script file and the second differential file repack compression, while in response to the second script file and the second differential file
It generates and needs to re-start signature, that is, be set to the second script file and second signed data at the second differential file both ends.By
Second script file, the second differential file and the second signed data are constituted suitable for each set-top box current version (i.e. this implementation
Example in set-top box current version 1, set-top box current version 2 and set-top box current version 3) difference upgrade patch packet.
When it is implemented, corresponding first script file of merging set-top box current version is：
Rootfs_ver_01_patch, rootfs_ver_02_patch and rootfs_ver_03_patch are merged and given birth to
At the second script file rootfs_update_patch.
Rootfs_update_patch is stored in patch_make/rootfs/update/patch/rootfs_
Update_patch compresses entire update catalogues, re-starts signature (generating the second signed data) and forms difference afterwards
The packet is broken into upgrading stream by upgrade patch packet update.tgz.
Set top box upgrading agreement is specially in step s 103：Difference upgrade patch packet is packaged into according to the format of TS packets
Whole section of TS streams, are issued to by front end cable lines in the memory of set-top box.Difference upgrade patch packet is downloaded to first and waits rising
