COFDM, or Coded Orthogonal Frequency Division Multiplexing, is a technique that’s commonly used for transmitting data over wireless channels, particularly in video streaming applications. It’s a digital modulation technique that’s able to encode data onto multiple carrier frequencies, which are then transmitted simultaneously. This allows for more efficient use of the available bandwidth and helps to mitigate against interference and signal degradation.
In sports production, COFDM is often used to transmit video and audio signals over short to medium distances. For example they can be used in a range of live sorts productions, such as in a football stadium, COFDM can be used to transmit video and audio signals from the cameras on the field to the control room, which may be located somewhere in the stadium. The distance between the cameras and the control room in this case is typically a few hundred meters to a few kilometers.
In some cases, COFDM can also be used to transmit data over longer distances in sports production. For example, in a cross-country ski race or a marathon, COFDM can be used to transmit video and audio signals from cameras and microphones along the course to the production truck, which may be located at the finish line. The distance between the cameras and microphones along the course and the production truck in this case can be several kilometers.li
The big advantage of utilizing COFDM and network links from Videosys is that they also offer a range of camera control features for remote production. This means camera cam be remotely operated.
In all cases, COFDM is able to transmit data over the required distances with minimal latency or delay. This means that the video and audio can be viewed and heard in real-time, which is essential in sports production.
In conclusion, COFDM can be used to transmit data over both short and long distances in sports production, depending on the specific requirements of the system. It’s a flexible and reliable technique that’s able to transmit high-quality video and audio signals with minimal latency or delay.
