Problems solved by technology

However, when used for high-resolution LED dome display, each channel transmits 4K high-resolution video frames internally, and each frame needs to be split and sent. In this process, it is difficult to guarantee the synchronous transmission of the video frames inside the channel. Can't support high-resolution LED ball screen display well

Embodiment 1

[0028] A method for synchronously sending video that supports high-resolution LED ball screen display, comprising the following steps:

[0029] a. Divide any single channel 4K high-resolution video frame into 16 parts of data;

[0030] b. For the video data of each part, the data is cached in the interval of 16 lines, and the address blocks are stored in sequence in groups of 16;

[0031] c. The video data is taken out from the data cache in units of groups, and the 135-line data of each channel is sent to 16 Gigabit Ethernet ports in parallel for sending until all groups are sent.

Embodiment 2

[0033] A method for synchronously sending video that supports high-resolution LED ball screen display, comprising the following steps:

[0034] a. Divide any single channel 4K high-resolution video frame into 16 parts of data;

[0035] b. For the video data of each part, the data is cached in the interval of 16 lines, and the address blocks are stored in sequence in groups of 16;

[0036] c. The video data is taken out from the data cache in units of groups, and the 135-line data of each channel is sent to 16 Gigabit Ethernet ports in parallel for sending until all groups are sent.

[0037]In the step a, the 4K high-resolution video frame is divided into 16 parts of data, the first part of data contains row numbers 1-135, the second part of data includes row numbers 136-270, and so on, the 16th part The data contains sequence numbers 2026-2160.

Embodiment 3

[0039] A method for synchronously sending video that supports high-resolution LED ball screen display, comprising the following steps:

Abstract

The invention discloses a video synchronous sending method supporting high-resolution LED ball screen display, which belongs to the technical field of video synchronous processing, and is characterized in that it comprises the following steps: a. Divide any single-channel 4K high-resolution video frame into N The data of each part; b, for the video data of each part, adopt the interval N row buffering mode to carry out data buffering, the address block is stored sequentially with N as a group of video signals; c, take out the video data from data buffering group as Unit, 2160 / N rows of data per channel are sent to N Gigabit Ethernet ports in parallel for sending until all groups are sent. For a single channel, the present invention can split a complete 4K high-resolution video frame into multiple Ethernet channels for transmission separately, and can ensure the synchronous transmission of 4K high-resolution video frames inside the channel, thereby supporting 4K high-resolution High resolution LED ball screen display.

Description

technical field [0001] The invention relates to the technical field of video synchronous processing, in particular to a video synchronous transmission method supporting high-resolution LED dome display. Background technique [0002] LED ball screen display is to splice multiple LED display modules together to form a spherical screen for image display. It has received more and more attention in simulation training. The images from the video source are corrected and cropped and then sent to the corresponding LED display module for display. These images are spliced ​​together to form a complete picture, which can provide users with a strong sense of immersion and a better sensory experience. The system has high requirements for video synchronization, and the lack of synchronization of each LED display module will affect the integrity and coherence of the displayed video and reduce the user experience. [0003] After the LED dome is unfolded, it generally has a large display ar...
