Discover 8K AV Distribution Solutions for Smart Campus


The research and development of the 8K standard began as early as 1995. By 2007, the Society of Motion Picture and Television Engineers (SMPTE) in the United States had recognized “7680 * 4320 line-by-line display” as the standard for “8K” resolution. 8K resolution can optimize video contrast, clarity, and color expressiveness for the better. In today’s article, we will explore together how 8K AV Distribution Solutions can be widely applied in smart campuses like this here. And know about its higher brightness and contrast, sharper edges, and greater depth of field features.

1. What is 8K?

The resolution of 8K is 7680*4320, which is called 1080P compared to full HD (1920*1080) video, and 8K is also called 4320P. More commonly, it is referred to as Ultra HD 8K or 8K for short. An 8K image has about 33 million pixels. It has 4 times as many pixels as a 4K image. It’s called 8K because the image is about 8,000 pixels wide, and the spec is still in the ultra-high definition category, hence the name Ultra HD 8K by some.

2. Basic parameters of 8K

The resolution is 7680×4320.

The color Bit width is 12-bit.

The color gamut standard is Rec.2020, which is 1.4 times the current NTSC color gamut.

The frame rate reaches 60p to 120p;

Support HDR high dynamic range, preferably dynamic HDR;

For audio, an immersive 3D audio effect based on audio objects was used, with 22.2 channels

3. Technical Advantages of 8K AV Distribution Solutions

8K Audio and video distribution solutions refer to technologies and devices for distributing and transmitting high-quality 8K video and audio signals to multiple displays or devices. And why does a smart campus require 4K or 8K AV Distribution Solutions? Here are some technical advantages of 4.8K AV Distribution Solutions.

3.1 Compatibility with existing systems

An important aspect of 8K AV distribution solutions is compatibility with existing systems of smart campus. Seamlessly integrate and scale AV systems without compromising quality.

3.2 Video Dissemination with High-Resolution

8K display can ensure high-definition picture display. Higher resolution means clearer picture details, richer color display, and better display of large display screens.

3.3 Audio and Video Processing

With the distribution of 8K video, audio and video processing capabilities are gradually becoming more advanced. Deliver an immersive audio experience for teachers and students alongside 8K visuals.

4. 8K is Not the Best, 4K is Equally Excellent

Compared to 4K, 8K screen devices tend to be more expensive, especially if you buy a larger interactive flat panel for your intelligent classroom, the cost will be very expensive.

While 8K can bring a high-definition display, it also means higher requirements for network transmission efficiency. For some occasions that requires  smooth transmission of information, 4K technology is still a good option at this stage.

4.1 4K vs 8K: Weighing the Trade-offs for Your Campus AV Needs

Instead, 4K resolution already offers highly detailed and impressive image quality, with four times as many pixels as a full HD TV. It not only has excellent visual presentation effects, but also has a higher price advantage.

4.2 Navigating the Resolutions

In addition, 8K videos have a huge amount of data and require compression and decompression during transmission, which involves video encoding and decoding technology. At present, the coding and decoding technology standards are constantly evolving and upgrading with the maturity of 8K technology. The traditional video encoding and decoding standard H.264 faces an insufficient compression ratio for 8K videos with excessive data volume, making it difficult to meet transmission requirements.

If you prioritize the highest level of detail and are willing to invest in a more expensive TV, 8K resolution may be a good choice, especially for l content, and more affordable options, 4K resolution is still an excellent choice.

5. The Most Cost-Effective 4K AV Distribution Solutions

If you are looking for a cost-effective 4K AV distribution solution, then I think our QNEX audio and video broadcast solution is a good choice for your smart campus.

The Q-NEX campus audio and video distribution solution is based on AV-over-IP technology. It can not only realize audio and video live broadcast but also broadcast audio and video to all classrooms and the space outside the classroom, such as the cafeteria, library, teacher’s office, corridor, reception hall, etc. By deploying the Q-NEX media server, Network Media Processor (NMP), and Media Box (MBX), this scheme realizes the distribution of audio, video, and control signals on the Internet by using the existing campus network.

6. The Application of 8K AV Distribution Solutions on Campus

Compared to 4K, 8K is more than just a 4x increase in the number of pixels and a larger image size. Behind the power of more detailed presentation is the continuous expansion of application scenarios.

6.1 AV-over-IP Technology

AV-over-IP solutions play a crucial role in 8K AV distribution. These solutions leverage the power of IP networks to transport audio and video signals, enabling flexible and scalable distribution of 8K content to multiple endpoints.

6.2 Enhanced Visual Learning Experience

8K resolution provides incredibly clear images, allowing students to see fine details and complex visual effects. It enhances visual learning by displaying complex charts, scientific illustrations, and high-resolution educational content. As the infrastructure of future IT technology, 4K/8K, together with cloud computing, AR/VR, and other technologies, will play an important role in realizing the whole life cycle management of teaching, restoring real case teaching scenes, and realizing high-quality resource sharing. It will completely overturn the traditional teaching mode of medical imaging, and play a great role in promoting the teaching and development of medical imaging.

6.3 Distance Learning and Distance Collaboration

The distance teaching system composed of an “HD camera +5G network +4K/8K” will be widely used. Inter-school teaching can be broadcast in real-time, forming a “curriculum alliance” for teachers and curriculum resource sharing. Centered on high-quality on-site teaching points, it can radiate to imaging students in medical colleges and universities around the world, and cross-school, cross-regional, multi-level “super class” will become a reality.


Building a smart campus is not only the purchase of large-scale intelligent equipment but also the need for systematic intelligent solutions, such as the audio broadcast transmission scheme mentioned in this paper. Technology continues to advance and the demand for high-quality audio-visual solutions in educational institutions continues to increase. The application of 8K AV distribution solutions in a campus environment can bring many benefits, enhancing the learning experience and facilitating effective communication.
