[0048] refer to figure 2 , figure 2As the first embodiment of the data transmission method of the present invention, the data transmission method includes the following steps:
[0049] Step S10, cache the data to be played and back it up to the backup storage area;
[0050] Described terminal equipment can be terminal equipments such as TV set, computer, and the CPU of terminal equipment can receive various data to be played, such as the digital data to be broadcasted of digital TV, the analog data to be played of analog TV, and the data connected by mobile phone through wireless network. The transmitted pulse-coded data to be played, the data to be played can be audio data and / or video data, and when the terminal device receives the data to be played, the data to be played can be uniformly converted into digital data to be played, stored and backed up at least one Copy the data to be played to the backup storage area.
[0051] Step S20, sending the data to be played in t...

The invention discloses a data transmission method. The method comprises the following steps: caching to-be-played data and backing up the cached to-be-played data to a backup storage area; sending the to-be-played data in the cache to a router, so that the router sends the received to-be-played data to a playing device; and when playing delay information sent by the playing device is received, sending the to-be-played data in the backup storage area to the playing device corresponding to the playing delay information, wherein the playing device, when the time interval of receiving the to-be-played data is greater than a preset time interval, sends the playing delay information to the terminal equipment. The effect of reducing data transmission interruption is achieved, and the intelligentlevel of data transmission of the terminal equipment is improved.
Description
technical field [0001] The invention relates to the field of computer technology, in particular to a data transmission method, device and medium. Background technique [0002] The connection between traditional smart TV and wireless audio requires a wireless network to connect to the router. On the one hand, the router first receives the audio data sent by the TV, and on the other hand, the router sends the received audio data to each connected surround sound. After the router is connected to multiple devices, the transmission process is delayed due to the blockage of the router, and the audio data of the TV cannot be transmitted to the speaker in time, resulting in the delay of the audio information during the audio transmission process, which leads to the interruption of the sound heard by the user. Contents of the invention [0003] The embodiment of the present invention provides a data transmission method, device and medium, aiming to solve the delay in the transmissi...
