Embodiment 1

[0050] In the method for writing TV attribute data provided in this embodiment, the TV is the execution subject, and the FLASH memory of the TV is preset with a storage block baseparam partition with special authority, and the storage block partition will not have a file system. Only raw partitions are provided. For the method of writing attribute data of this TV, see figure 1 , the method may include the following steps:

[0051] Step S102: Obtain the attribute data to be written into the TV set.

[0052] When the attribute data is written into the FLASH memory of the TV set, the attribute data is first obtained, and the attribute data may be input by the user or transmitted from other storage devices. The method for writing the attribute data of the TV set can be used for the TV set before leaving the factory. Before leaving the factory, the above-mentioned storage block partition is set for the FLASH memory built in the television microprocessor, and the attribute data to ...

Embodiment 2

[0058] This embodiment is a further preferred method for writing TV attribute data on the basis of Embodiment 1, see figure 2 , the method may include the following steps:

[0059] Step S202: Obtain the attribute data to be written into the TV set.

[0060] Step S204: calling the interface function of the storage block partition.

[0061] Step S206: Verifying the attribute data to obtain a verification value corresponding to the attribute data.

[0062] When checking, you can use the CRC check method (Cyclic Redundancy Check, cyclic redundancy check), or you can use the MD5 check method (Message Digest Algorithm 5, the fifth edition of the message digest algorithm), or other checks method. Among them, since the data volume of the attribute data is small and the structure is simple, it is simpler to use the MD5 verification method, and the processing speed is fast.

[0063] When the attribute data is written, the check value of the attribute data is written at the same tim...

Embodiment 3

[0075] Corresponding to the method for writing TV attribute data provided in Embodiment 1 of the present invention, the embodiment of the present invention also provides a device for writing TV attribute data, the device is set in the TV, and the FLASH memory of the TV A storage block baseparam partition with special permissions is preset. This storage block partition will not have a file system and only provide raw partitions. see image 3 , the device may include an acquisition module 320 , a calling module 340 and a storage module 360 ​​.

[0076] The obtaining module 320 is used for obtaining the attribute data to be written into the TV set.

[0077] When attribute data is written in the FLASH memory of TV, at first obtain this attribute data by acquisition module 320, this acquisition module 320 can be the input interface that receives user's input, thus user can input attribute data, also can be with other The transmission interface connected to the storage device, so ...

Abstract

The invention discloses a television, and writing and reading methods and devices of property data thereof. A FLASH memory of the television is preset with a storage block partition. The storage block partition is not provided with a file system and only provides an exposed partition. The writing method of the property data of the television comprises the following steps: obtaining the to-be-written property data of the television, scheduling the interface function of the storage block partition, and storing the property data in the storage block partition through the interface function. According to the invention, a user cannot modify the property data of the storage block partition so that the property data can be permanently stored and is not lost due to wrong operation of the user, and intelligent television network application errors or operation errors caused by the easily lost property data are prevented.

Description

technical field [0001] The present invention relates to the technical field of televisions, in particular, to methods and devices for writing and reading televisions and attribute data thereof. Background technique [0002] With the intelligent development of information access terminals such as mobile phones and tablet computers, TVs are also gradually entering the process of intelligent development, so as to realize cross-platform search between TVs, networks and programs, and users can access the information they need at any time. [0003] When smart TVs use the network for authentication and obtain personalized upgrade services, etc., it is often necessary to use their own fixed internal application or operating system attribute data as identification information, such as TV ID number, MAC value, product model, hardware The version number and some fixed accounts and passwords are uploaded to the server, and the server responds according to the identification information...
