Problems solved by technology

[0007] There are multiple sub-addresses in the TCON chip in the prior art. It can be seen that the FRC control program needs to be frequently rewritten to adapt to the parameters of different TCON chip sub-addresses. It can be seen that this solution increases the workload of the designer.

Embodiment approach 1

[0108] Embodiment 1, the indication information is the target sub-address and system parameters.

[0109] That is to say, the second device directly sends the target subaddress and system parameters to the first device. In this solution, the first device can reduce the workload, that is, it only needs to receive the target sub-address and the system parameters directly, and there is no need to perform a series of method procedures to determine the system parameters.

Embodiment approach 2

[0110] Embodiment 2, the indication information is the target sub-address. That is to say, the indication information only includes the target subaddress, and the target subaddress is used to enable the first device to determine the operation object of the first control command. In this way, the data load transmitted by the second device to the first device is reduced, and network overhead is saved. On the other hand, the first device needs to determine the system parameters corresponding to the target subaddress according to the target subaddress. An optional implementation manner is that the first device determines the system parameter according to a preset correspondence table between each sub-address and the system parameter in the third device.

[0111] In the embodiment of the present invention, the first device presets the correspondence table between each sub-address and the system parameter in the third device. Find the system parameter corresponding to the target s...

Abstract

An embodiment of the invention relates to the communication field and especially relates to a control command forwarding method and an apparatus thereof. In order not to rewrite a first equipment control program, a command sent by second equipment is sent to a plurality of subaddresses of third equipment. In the embodiment of the invention, first equipment receives indication information sent by the second equipment and a first control command corresponding to a target subaddress and determines a system parameter; if the first control command is determined to be a writing command, according to the system parameter, the first control command is decoded, data to be written in is acquired and is sent to the target subaddress; and if the first control command is determined to be a reading command, a second control command generated according to the first control command is sent to the target subaddress, and according to the system parameter, the returned data to be read is decoded and is returned to the second equipment. In the invention, under the condition that the first equipment control program is not rewritten, a plurality of commands sent by the second equipment are sent to different subaddresses of the third equipment of the plurality of system parameters.

Description

technical field [0001] The embodiments of the present invention relate to the communication field, and in particular, to a method and device for controlling command forwarding. Background technique [0002] With the wide application of television products, people have higher and higher requirements for the picture quality of televisions. During the picture quality control process of TV, the timing control circuit (Timing Controller, TCON) of the display is generally controlled by the System on a Chip (SOC) chip, but in order to improve the picture quality, a The Frame Rate Conversion (FRC) chip performs image quality processing to improve the clarity of moving images. In this case, the bus of the FRC chip is generally connected to the TCON chip. If the bus of the SOC chip and the bus of the FRC chip are connected to the TCON at the same time, when the SOC chip needs to send a control command to the TCON chip, a bus conflict will occur. [0003] In the prior art, in order ...
