The exemplary embodiments and descriptions of the present invention are provided to explain the present invention, but not to limit the present invention.
Example 1
An embodiment of the present invention provides a method for upgrading software of a digital television, as shown in fig. 1, the method includes:
and 104, downloading the corresponding file according to the description information.
In this embodiment, in step 102, when the digital television sends an upgrade request to the server, after the server receives the upgrade request, the file to be upgraded may be packaged to generate description information of the file to be upgraded, where the description information of the file package may be referred to as "image file description information"; and returning the description information of the file to be upgraded to the digital television, so that the digital television downloads the file according to the description information.
In this embodiment, the description information may include, in addition to the above information, one or a combination of the following information: the data Size (Image Size) of the file to be upgraded, the number (filename) of the file to be upgraded, and the Size (Filesize) and location (Filelocation) of each file in the package, but are not limited to the above information, and may include other required information.
Therefore, the files needing to be upgraded can be determined according to the product models or the product identifications, and the number of the upgrading files contained in the generated file package is minimum as the server only determines the files needing to be upgraded, so that redundant data transmitted on a network can be reduced, time consumed by upgrading is reduced, and upgrading efficiency is high.
In this embodiment, before step 101, the method may further include: triggering software upgrading; the triggering software upgrading can adopt two modes, namely an automatic mode and a manual mode; wherein, the automatic mode includes: triggering software upgrading according to preset time, namely periodically triggering the software upgrading, for example, triggering the software upgrading once every 5 days; the manual mode includes: the software upgrade is triggered according to the received upgrade instructions input by the user, e.g., the user may trigger the software upgrade through menu selection. Thus, after triggering the software upgrade, step 101 is performed.
As shown in fig. 2, the digital television in step 101 may determine whether software upgrade is needed or not by the following method:
In this embodiment, after the digital television sends the relevant information to the server in step 201, when the server receives the relevant information, the server compares the current version information in the relevant information with the latest version information stored in the server, finds the file to be upgraded, and generates the upgraded relevant version information of the file to be upgraded; and returning the updated related version information to the digital television, so that the digital television downloads files according to the description information. As shown in fig. 3, in step 203, the digital television determining whether a software upgrade is required according to the version-related information of the upgrade may include:
if the software upgrading is triggered by adopting the automatic upgrading mode, when the minor version number in the related information of the upgraded version is larger than the minor version number of the current version information, the file needing upgrading is not an important upgrading file, the upgrading can be abandoned, and the time spent on upgrading is long, so that the influence of frequent non-important upgrading on daily use of a user can be reduced, and the latest television function can be enjoyed at any time.
In this embodiment, in step 103, the server returns the description information of the file to be upgraded according to the upgrade request, not the description information of all files, but only the description information of the file to be upgraded, that is, the description information of the upgrade file containing the minimum upgrade data, so that redundant data transmitted on the network can be reduced.
In this embodiment, after the digital television receives, in step 103, description information of a file to be upgraded, which is returned by the server according to the upgrade request, the method further includes: the description information is stored.
And after downloading the corresponding file according to the description information in step 104, the method further comprises: setting a downloading identifier for the downloaded file; for example, for a file already downloaded, a flag bit may be set to "1", a file not downloaded may not be set, or a flag bit may be set to "0", so that when the current download of the digital television fails or the user abandons the current download and downloads the file again later, the file not downloaded may also be downloaded according to the stored description information and the set download identifier, without downloading all the files, so that the upgrade time of the user may be reduced and the network load may be reduced. Wherein, the corresponding flag bit can be set in the stored description information.
In this embodiment, in order to further reduce the network load or increase the success rate of transmission in case of network congestion, when downloading a file, a file that needs to be upgraded may be downloaded in blocks, and after downloading a corresponding file in blocks according to the description information, a download identifier may also be set for the downloaded file block.
According to the embodiment, through information interaction between the digital television and the server, the server automatically generates the description information needing to be upgraded for the digital television according to the upgrading request, namely the description information of the upgrading file containing the minimum upgrading data, and transmits the description information to the digital television through the network, so that the redundant data transmitted on the network can be reduced;
the digital television stores the received description information and identifies the downloaded file, so that when the current downloading of the digital television fails or a user abandons the current downloading and downloads the file again later, the digital television can download the file which is not downloaded according to the stored description information and the set downloading identification without downloading all the files, thereby reducing the upgrading time of the user and lightening the network load;
furthermore, by downloading the files in blocks, the network load can be further reduced, or the success rate of the transfer can be increased in case of network congestion.
Example 2
The embodiment of the invention provides a software upgrading method for a digital television, which is described in detail below with reference to fig. 4.
As shown in fig. 4, the method includes:
step 401, triggering software upgrading by the digital television;
the triggering software upgrading can adopt two modes, namely an automatic mode and a manual mode; wherein, the automatic mode includes: triggering software upgrading according to preset time, namely periodically triggering the software upgrading, for example, triggering the software upgrading once every 5 days; the manual mode includes: the software upgrade is triggered according to the received upgrade instructions input by the user, e.g., the user may trigger the software upgrade through menu selection.
Step 402, after triggering software upgrade, the digital television sends related information to a server, where the related information refers to description information of a version related to the digital television itself, and the related information may include: current version information including major version numbers and minor version numbers, and one or a combination of the following information: the Name of the Product family (Model Name), the Product Model number (Product Name) belonging to the Product family, and the Product identification (Device ID) belonging to the Product Model number.
Step 403, after receiving the relevant information, the server compares the current version information in the relevant information with the version information of the latest software stored in the server itself, and finds files that need to be upgraded, for example, 5 files that need to be upgraded;
step 404, returning the related information of the upgraded version to the digital television; the content of the updated version-related information is as described in embodiment 1, and is not described herein again.
Step 405, the digital television judges whether upgrading is needed; the determination method is as described in embodiment 1, and is not described herein again.
Step 406, in step 405, if it is determined that the upgrade is needed, an upgrade request is sent, where information included in the upgrade request is as described in embodiment 1, and is not described herein again.
Step 407, the server generates the description information of the file to be upgraded according to the upgrade request, which may be referred to as "upgrade mapping file description information";
wherein, the description information may include: the Name (Image Name) of the file to be upgraded, the link address (Image Url), and Version information (Version) including a Major Version Number (Major Number) and a minor Version Number (MinorNumber);
in addition, the description information may further include one or a combination of the following information: the data size of the files to be upgraded, the number of files to be upgraded, and the size and location of each file in the file package, but are not limited to the above information, and may include other required information.
Step 408, the server returns the description information of the file to be upgraded to the digital television.
Step 409, after the digital television receives the description information of the file to be upgraded returned by the server according to the upgrade request, the description information is stored.
Step 410, downloading a corresponding file according to the description information;
wherein, the corresponding file can be downloaded from the server according to the link address in the description information.
Step 411, storing the downloaded file, and identifying the downloaded file;
the storage unit of the digital television can be divided into two spaces, wherein one space stores the files in use; the other space stores the downloaded file and is called as a spare space;
in the embodiment, the downloaded file can be stored in the spare space, so that the service life of the storage unit can be delayed by storing the downloaded file and the original file in different storage spaces, and the condition that a user cannot start the digital television due to update failure can be avoided;
the downloaded file may be provided with a download flag in the description information, and when the download flag is set for the downloaded file, for example, for the downloaded file, the flag may be set to "1", the un-downloaded file may not be set, or the un-downloaded file may be set to "0", so that when the current download fails or the user abandons the current download and re-downloads the file later, the un-downloaded file may be downloaded according to the stored description information and the set download flag, without downloading all files, so that the upgrade time of the user may be reduced and the network load may be reduced.
Step 412, judging whether the file needing to be upgraded is downloaded completely; if the judgment result is yes, file updating is carried out, namely the starting pointer points to the updated file;
thus, the space originally storing the file in use becomes the spare space, and when the digital television is started again, the file in the storage space pointed by the start pointer can be used.
In addition, in this embodiment, in order to further reduce the network load or increase the success rate of transmission in case of network congestion, when downloading the file in step 410, the file that needs to be upgraded may be downloaded in blocks, and after downloading the corresponding file in blocks according to the description information, a download identifier may also be set for the downloaded file block.
In this embodiment, the server may divide the downloaded file into file blocks according to types, for example, the file types may include a boot loader (boot), a kernel (kernel), a root file system rootfs, a resource file (resources), open source software (opensrc), a browser (browser), a game (game), a font (font), and the like, and each type of file block is downloaded several times according to the size principle: for example, if the size of the game is 10M, the download may be divided into 5 times; and the boot size is 1 million, one download is complete.
In this embodiment, before downloading the corresponding file according to the description information in step 410, the method may further include: determining whether a part of files or file blocks are downloaded in the files needing to be upgraded according to the pre-stored description information and the downloading identification; if the judgment result is yes, only downloading the files or file blocks which are not downloaded in the files needing to be upgraded; thus, when the user abandons the current software upgrade actively or passively due to uncontrollable reasons such as network and triggers the software upgrade again, after step 409, if the digital television finds that the received description information of the file to be upgraded is the same as the stored description information, it can determine which files have not been downloaded according to the download identifier, and continue downloading the files that have not been downloaded last time without starting downloading from the beginning, thereby reducing the network burden and saving the upgrade time of the user.
According to the embodiment, through information interaction between the digital television and the server, the server determines the file to be upgraded according to information such as equipment identification, model and the like of the digital television, automatically generates the description information to be upgraded for the digital television according to the upgrade request sent by the digital television, namely the description information of the upgrade file containing the minimum upgrade data, and transmits the description information to the digital television through the network, so that redundant data transmitted on the network can be reduced. In addition, the digital television can download files needing to be upgraded in a blocking mode, and identify the downloaded files or file blocks, so that when a user abandons the current software upgrade actively or passively due to uncontrollable reasons such as a network and triggers the software upgrade again, the files which are not downloaded last time are downloaded continuously without starting downloading from the beginning, the network burden is relieved, and the upgrading time of the user is saved.
