1. What are the quality requirements for LED display screens for synchronous live broadcasting?
The quality requirements for LED display screens for synchronous broadcasting live broadcasts mainly include the following aspects:
1). Use a synchronized player
This is the most important point. If you want to use your LED display screen to broadcast a football game live, you must use a synchronized player. Asynchronous broadcasting cannot be performed.
2). High résolution
High resolution can present more delicate and clear images and text, which is essential for the display of details in live content.
Especially when it is necessary to display product details, anchor expressions or sports scenes, high resolution can ensure that the audience has an excellent visual experience.
Generally speaking, the resolution should be at least 2K, and even 4K or higher resolution display screens can be considered. This will not only clearly display the live content but also ensure the clarity and fineness of the image.
3). High luminosité and contrast
- Luminosité:
The brightness of the LED display needs to be determined according to the installation environment. For indoor environments, a brightness of 600 — 800cd/m² is more appropriate; in outdoor environments, it needs to reach 1500 — 3000cd/m² to ensure that the picture is still clearly visible under strong light.
High brightness helps to overcome the interference of ambient light and maintains the clarity and color reproduction of the picture.
- Contraste:
Contrast refers to the ratio of the brightest area to the darkest area when displaying an image. High contrast can enhance the layering and three-dimensional sense of the image, making the picture brighter and the colors more vivid.
Generally speaking, the higher the contrast, the better, but the comprehensive influence of other parameters must also be considered in the actual selection.
4). Wide angle de vue
A wide viewing angle can ensure that viewers in different positions can see clear and consistent pictures, avoiding color and brightness deviations. This is especially important for large live broadcast rooms or occasions with a large number of viewers.
Usually, LED display screens should have a large viewing angle (such as horizontal and vertical viewing angles of more than 160°) to ensure that viewers can get a good viewing experience from all angles.
5). High fréquence de rafraîchissement
High refresh rate can reduce the flickering and smearing of the picture, making the dynamic picture smoother. This is especially important for showing fast-moving scenes or product demonstrations.
Generally speaking, the refresh rate of LED display screens should reach or exceed 120Hz or even higher (such as 144Hz, 165Hz, etc.) to ensure that the audience can feel the continuity and smoothness of the picture when watching the live broadcast.
6). Stability and reliability
Synchronous live broadcast requires LED display screens to have high Stability and reliability to avoid failures or interruptions during the live broadcast.
Choose brands and products with reliable quality and good Stability to reduce the frequency of failures and repairs. At the same time, attention should be paid to detail processing during installation and debugging to ensure that the equipment connection is stable and reliable and the heat dissipation is good.
2. How to connect the LED display screen to live broadcast via computer?
To connect the LED display screen to live broadcast and achieve synchronous control via computer, you can mainly follow the following steps:
1). Préparation
1.1). Equipment selection:
Choose a suitable LED display screen to ensure that its resolution, brightness, contrast and other parameters meet the requirements of live broadcast.
Prepare a computer with stable performance as the playback and control center of the live broadcast content.
According to the interface type of the computer and LED display screen, prepare the corresponding connection cables, such as HDMI cable and network cable.
1.2). Environment layout:
Ensure that the LED display screen is installed firmly and at a suitable viewing angle and height.
Check the light, temperature and other conditions of the viewing environment to ensure that the audience can watch the live broadcast content comfortably.
2). Connecting equipment
- Connecting the video processor from the computer uses an HDMI connection:
If both the computer and the LED display screen support the HDMI interface, the HDMI cable is preferred for connection.
Plug one end of the HDMI cable into the HDMI output interface of the computer and the other end into the HDMI input interface of the LED display screen.
Then, start the computer and LED display screen, and select the signal source according to the prompts of the display screen (usually select HDMI mode).
- The connection from the video processor to the LED display is made by using a network cable:
For the application of LED display, Ethernet cables such as CAT5e or CAT6 are usually selected, as they have high data transmission rates and good anti-interference capabilities.
Plug one end of the network cable into the network port of the video processor and the other end into the network port of the LED display (or transfer through a network device such as a switch).
Make sure that the video processor and the LED display are in the same network segment so that they can communicate with each other. This usually involves setting network parameters such as IP address and subnet mask.
3). Settings
After connecting the computer and the LED display, because your LED display is a synchronous control system, your LED display will display what the computer displays.
At this time, you just need to open the live broadcast software and select the live broadcast of the football game you need to play.
4). Testing and optimization
4.1). System test:
Perform system testing before the official live broadcast, including Testing of video playback, audio output, and picture synchronization.
Ensure that all devices are working properly and compatible with each other without conflict.
4.2). Optimization and adjustment:
Make necessary optimization adjustments based on the test results, such as adjusting the settings of the playback software, changing the connection cable, etc.
Ensure that the picture is clear and smooth and the sound is clear and noise-free during the live broadcast.
3. Precautions when using LED display screens for live broadcast viewing
When using LED display screens for live broadcast viewing, you need to pay attention to the following aspects to ensure the smooth progress of the live broadcast and a good experience for the audience:
1). Choose the right LED display screen:
Choose an LED display screen with appropriate resolution, brightness, contrast, and other parameters according to the live broadcast content and viewing distance.
For example, for live broadcasts of sports events, you may need to choose a high-definition full-color screen to ensure a clear picture, while for educational lectures, a simple and elegant single-color or two-color screen may be more suitable.
Make sure that the size and resolution of the LED display screen can meet the needs of live broadcasts to avoid blurry or distorted pictures.
2). Correctly install the LED display screen:
Fix the LED display screen on a stable bracket or background wall to ensure that it will not shake or fall off during the live broadcast.
Adjust the tilt angle and height of the display screen so that the audience can watch the live broadcast content comfortably.
3). Ensure a stable signal:
Use high-quality cables (such as HDMI cables, optical fibers, etc.) to connect the LED display screen to the video processor or live broadcast device.
Check whether the signal cable is firmly connected to avoid signal interruption or interference.
4). Debugging display effects:
Adjust the brightness, color, contrast, and other parameters of the LED display to ensure that the picture display effect is excellent and not dazzling.
Check whether there are any pixel damage or display abnormalities, and repair them in time.
