Problems solved by technology

If the buffer area is set too small and the received video data is too large, the TV has not had time to process the previous video data, and the next video data comes again, the previous video data will be discarded, resulting in video packet loss or Frame loss; and if the buffer area is set too large and the received video data is small, there will be more video data in the buffer area that does not reach the video display area, resulting in video delay

Embodiment Construction

[0045] Specifically, as figure 1 As shown, an embodiment of the present invention proposes a method for dynamically adjusting cache, including:

[0046] Step S101, when the display terminal receives a video packet, adjust the size of each receiving buffer space according to the size of the video packet;

[0047] Wherein, each receiving buffer space has been preset or uses a default receiving buffer space. When the display terminal receives a video packet through the wireless high-definition technology, it first transmits the video packet to the receiving buffer, and then processes it into a video frame.

[0048] In this embodiment, the receiving buffer space is mainly used to buffer the video packets transmitted wirelessly. Since the size of the received video packets varies according to the content of the video, and the video data needs to be displayed quickly, the receiving buffer space should be Set the appropriate size, neither too large nor too small.

[0049] If the si...

Abstract

The invention relates to a method for dynamically adjusting cache and a display terminal. The method includes: when the display terminal receives a video packet, adjusting the size of each receiving cache space according to the size of the video packet; judging whether the size of the video packet is larger than the last video packet or not and the difference between the two is larger than a preset value or not to acquire a judging result; if the judging result is negative, adjusting the size of each decoding cache space according to the size of a video frame after the video packet is processed into the video frame; if the judging result is positive, adjusting the size of each decoding cache space according to the size of each receiving cache space, and adjusting the size of each decoding cache space according to the size of the video frame. By the method, packet loss and frame loss of wireless transmission can be reduced, and video time delay can be reduced.

Description

technical field [0001] The invention relates to the technical field of display terminal data buffering, in particular to a method for dynamically adjusting buffering and a display terminal. Background technique [0002] With the popularization of wireless technology, the use of various connecting wires has been greatly reduced, and users can directly connect mobile phones or computers to TVs in a wireless manner, and share images of mobile phones or computers on TVs. [0003] At present, there are many ways of wireless transmission, such as Samsung's ALLSHARE, Apple's AIRPLAY, TCL's multi-screen interaction, and INTEL's WIDI technology. WIDI (Intel Wireless Display, wireless high-definition technology) realizes the wireless connection between smart terminals and display devices through WIFI signals. As long as it is equipped with INTEL's I series CPU (such as i3, i5, i7) It is possible to wirelessly connect to a display device such as a TV through a wireless receiving adapt...
