The invention discloses a WIFI-based ultra-high-definition video sending and receiving method and device, and the method comprises the steps: a sending device processes an obtained ultra-high-definition video through a compression algorithm, and obtains code stream data; the sending device packages the code stream data into a data packet; the sending device sends the data packet to a receiving device through a WIFI communication module integrated in the sending device; and the transmission rate of the WIFI communication module is not lower than a first threshold value. According to the invention, after the data compression is carried out on the ultra-high-definition video, the data to be transmitted is reduced, the transmission time delay is reduced, the ultra-high-definition video transmission is carried out through the WIFI network, the complex communication line wiring operation is avoided, and the wiring cost is also reduced.
Description
technical field [0001] The present invention relates to the technical field of WIFI transmission, in particular to a method and device for sending and receiving ultra-high-definition video based on WIFI. Background technique [0002] At present, the communication between most traditional devices (video source devices such as set-top boxes and display devices) is realized through cables, but the communication lines are relatively complicated, the cost of wiring is high, and the delay is high; It is difficult for the device to play ultra-high-definition video in DVD and other video devices with ultra-low latency. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method and device for sending and receiving ultra-high-definition video based on WIFI by combining WIFI network and compression algorithm. [0004] In order to solve the above technical problems, the present invention provides a WIFI-based ultra-high-defin...
