In the previous two issues, we provided a detailed introduction to the OBV-2800 compact mobile broadcasting van. You are now familiar with the evolved OBV-2800 CCU edition, which boasts significant functional enhancements compared to its predecessor, nearly approaching the functionality of large-scale broadcasting vans. In this issue, we will share insights into the OBV-2800 broadcasting van with CCU functionality, exploring the unique changes in its applications and how it enhances the use of OBV-2800 in EFP multi-camera operations.

One of the primary advantages of compact mobile broadcasting vans in applications is their speed, lack of space constraints, and streamlined manpower. They can penetrate every location without the need for large auxiliary desks and chairs, quickly completing multi-camera operations. With the increasing prevalence of cable, wireless, and satellite television, and the diverse nature of program content in today's era, different program types define a television station's uniqueness. The ability to present diverse television content that closely aligns with viewer preferences sets the stage for a distinct television experience. Especially for local events such as temple festivals, folk activities, regional celebrations, and more, these types of programs can create a special and meaningful viewing experience. Mobile broadcasting systems with quick mobility play a crucial role in achieving this, and compact mobile broadcasting vans are especially well-suited for such purposes.

In a previous Datavideo monthly publication, we shared several case studies highlighting the advantages of compact mobile broadcasting vans, and we believe these examples are still fresh in your memory.

The above four cases of compact mobile broadcasting vans are just a simple illustration. The mobility of compact mobile broadcasting vans is not inferior to that of mobile broadcasting systems; in fact, it even surpasses the advantages of on-site installation of mobile broadcasting. Especially in situations like the Chinese mainland's Spring Festival travel rush, the application of broadcasting vans is definitely superior to that of mobile setups. This is because compact mobile broadcasting vans can follow the flow of holiday traffic, providing live broadcasts along the way, a task that mobile broadcasting systems cannot accomplish.

The application of compact mobile broadcasting vans is likely familiar to everyone, especially seasoned broadcasters who may view mobile broadcasting systems as their target equipment, and owning a broadcasting van might be a dream. Therefore, the application system diagram of the OBV-2800 CCU broadcasting van below can offer a new perspective for those choosing a compact mobile broadcasting van.

The main function of CCU integrated into the OBV-2800 is to consolidate auxiliary functions for EFP multi-camera operations. Through the transmission of comprehensive cables, CCU can establish the optimal connection between the broadcasting van and cameras, maximizing operational and application effectiveness.

In the basic application connection diagram below, we will analyze the CCU edition of the compact mobile broadcasting van, consolidating its functions and application architecture.

A compact mobile broadcasting van equipped with CCU primarily utilizes proprietary cables to connect the broadcasting and camera auxiliary functions. The functions include five main items, which are crucial when leading EFP multi-camera operations.

1. Transmission of camera-captured images to the broadcasting machine.
2. Review of images by the broadcasting machine sent back to the camera.
3. Communication and Tally light signal transmission between the broadcasting and camera.
4. Monitoring of camera images through an oscilloscope, followed by remote adjustment of camera parameters by the controller.
5. Power supply for camera and other accessories (such as monitoring screens) needed.

Therefore, the CCU system's main purpose is to integrate and execute the aforementioned five major functions within the CCU's system architecture, facilitating interactive connections between broadcasting and cameras. This ensures that the overall equipment for EFP multi-camera operations is integrated into a single system structure, delivering the fastest, most comprehensive, and concise application effects.

The proprietary CCU cables are constructed with 26-pin connectors, emphasizing quality and safety, especially considering their primary use in the OBV-2800 compact mobile broadcasting van. Given that cable connectors are frequently disassembled and impacted, making them prone to damage, these CCU proprietary cables are specially designed with a collision-resistant alloy to ensure the safe and secure operation of the OBV-2800 CCU compact mobile broadcasting van.

Another noteworthy feature is the oscilloscope function. Typically, in regular EFP teams, real-time signal detection with an oscilloscope is rarely available. However, within the comprehensive CCU system, the oscilloscope plays a crucial role. The images and data inspected by the oscilloscope allow for direct adjustment of each camera's aperture, color saturation, black and white balance, etc., using the remote controller for the cameras. This ensures that the images from each camera position tend to have similar quality. Therefore, in the CCU compact mobile broadcasting van system, the importance of the oscilloscope is no less than any other equipment, although currently, EFP teams familiar with oscilloscope usage are rare outside of television stations.

The last feature to mention is the accessory product for the OBV-2800 CCU compact mobile broadcasting van, which is the SLED bracket for professional cameras. Typically, large broadcasting vans are equipped with SNG cameras (as shown in the diagram below). If you want the cameras on a compact mobile broadcasting van to have the functionality of SNG cameras, the SLED bracket (as shown in the conceptual diagram) enhances this capability. It seamlessly integrates with the overall CCU structure, allowing even a compact mobile broadcasting van to achieve the applications of a large broadcasting van. This turns the entire application into a downsized version of a television-grade broadcasting van, without compromising any functionality.

Recently, some manufacturers have specifically developed the ability for compact mobile broadcasting vans to use 4G communication to transmit the van's images in real-time. This is a fantastic innovation, and if it can truly combine 4G communication to transmit the live broadcasting van's images, it will undoubtedly elevate compact mobile broadcasting vans to a new level. We eagerly await the step-by-step development of compact mobile broadcasting vans.
