Based on the hardware architecture of the data transmission device, the embodiment of the data transmission method is provided.
Referring to fig. 2, fig. 2 is a first embodiment of a data transmission method according to the present invention, the data transmission method includes the following steps:
step S10, caching the data to be played and backing up the data to a backup storage area;
the terminal device may be a terminal device such as a television, a computer, etc., where the CPU of the terminal device receives various data to be played, such as digital data to be played of a digital television, analog data to be played of an analog television, and pulse encoded data to be played sent by a mobile phone through a wireless network connection, where the data to be played may be audio data and/or video data, and when the terminal device receives the data to be played, the data to be played may be uniformly converted into the digital data to be played, and at least one copy of the data to be played is saved and backed up to a backup storage area.
Step S20, the data to be played in the buffer memory is sent to a router, so that the router sends the received data to be played to playing equipment;
further, the data to be played in the buffer memory is loaded to a first preset frequency band through a wireless network and sent to the router, and the first preset frequency band can be set to be 2.4Ghz. When the router receives the data to be played in the 2.4Ghz frequency band, the data to be played loaded through the wireless network is unloaded and stored, and the storage position is related to the type of the playing equipment. The router loads a second preset frequency band through the wireless network and sends the second preset frequency band to the playing device, wherein the second preset frequency band can be set to be 2.5Ghz.

The playing delay information is generated by the frequency band identification and the number corresponding to the current delay data segment.
The playing delay information is an infrared instruction, and is sent by the playing device, when the playing device receives the data to be played sent by the router, the playing delay information is sent to the terminal device when the time interval of the playing device is larger than the preset time interval, the preset time interval can be 2s, or can be set according to actual conditions, and when the time interval is larger than the preset time interval, the situation that the data to be played sent by the terminal device is blocked in the transmission process of the router is indicated, so that the playing delay information needs to be sent to the terminal device, the terminal device sends the data to be played again according to the playing delay information, and the playing delay information comprises the number corresponding to the data to be played in current delay, the backup address and other information. When the terminal equipment receives the playing delay information sent by the playing equipment, the data to be played in the backup storage area are sent to the playing equipment corresponding to the playing delay information according to the number corresponding to the data to be played in the playing delay information and the backup address information.

And when the playing equipment calculates that the time interval for receiving the data to be played is larger than the preset time interval, generating playing delay information according to the number corresponding to the delayed data to be played and the backup address information, and sending the playing delay information to the terminal equipment. When the terminal equipment receives the playing delay information sent by the playing equipment, the backed-up data to be sent is directly sent to the playing equipment through the wireless network from the backup storage area according to the number of the delayed data to be played corresponding to the playing delay information and the backup address. Therefore, the playing device can send the playing delay information to the terminal device when the router is blocked, and can directly send the backup data to be played to the playing device through the wireless network when the terminal device receives the playing delay information, so that the router can be bypassed when the router is blocked, the data to be played can be directly sent to the playing device through the wireless network, the effect of reducing interruption of data transmission is achieved, and the intelligent level of data transmission of the terminal device is improved.
