Applications and Discussion of Virtual Studios in the Market

Virtual studios have been widely used in television stations for many years, almost becoming essential equipment. They are categorized into single virtual backgrounds, simulated virtual PTZ (pan/tilt/zoom) effects without tracking, available in both 2D and 3D. Additionally, there are physical tracking systems, with single/multiple camera positions and features like boom arms, predominantly using 3D backgrounds. The system can be operated manually or remotely, providing outstanding effects but at a high cost, mainly adopted by large television stations.

In television stations, single virtual backgrounds are commonly used for photos, images, videos, etc., with multi-camera setups being prevalent, while single-camera setups are often employed for training purposes. They enhance trainees' expressive abilities in front of the camera or are used for recording training courses. Switching between different virtual backgrounds adds richness, entertainment, and an edutainment aspect to the content, facilitating effective distance learning.

Virtual studios with PTZ effects demonstrate excellent results. With technological advancements, even single-camera setups with only 2D effects can simulate multi-camera setups and PTZ effects without tracking, showcasing the impressive capabilities of modern technology. These simulated tracking virtual studios, suitable for users not requiring elaborate background effects, are cost-effective and user-friendly. They find extensive use in news, weather, talk shows, sports, and shopping channels by television stations.

For those seeking 3D effects with hardware trackers, the virtual effects produced are astonishing due to current 3D rendering techniques. Choosing a virtual studio depends on budget constraints and specific requirements. The use of tracking systems is prevalent in medium to large-sized television stations, and the demand is limited. In contrast, the demand for virtual studios is substantial in corporate marketing videos and educational videos for distance learning, far exceeding television station usage. A system that is affordable, versatile, and offers various virtual backgrounds to cater to different applications, coupled with the high-speed internet transmission rates of 4G and future 5G, makes video the most widespread and effective method of conveying information quickly and efficiently.

As an example, online distance education through video content is becoming increasingly common, with platforms like edX (https://www.edx.org), a joint initiative by MIT and Yale. Teachers using virtual studios for recording educational programs can create more engaging and interesting content, enhancing student interest and learning outcomes. Moreover, in the business sector, the use of videos for product introductions is efficient and cost-effective. These two markets far surpass the limited number of television stations, making it worthwhile for virtual studio suppliers to explore and develop further.
