relied more on traditional satellite- based systems for live news and events coverage; however, these systems can be limited in their scope. With a satellite-based system, users need to keep the ENG camera close to the vehicle or they will not be able to receive the signal. Using these systems, mobility and indoor coverage are nearly impossible unless a complex and costly infrastructure is set up. This approach is not ideal in scenarios where broadcasters need to cover breaking news. For example, to broadcast the Tour de France live using a traditional satellite- based system, one would need a helicopter, an airplane, and a satellite base station. This kind of system is heavy, costly, and complex. Therefore, we generally only see such systems being deployed for a small percentage of major sports events in the world. Thanks to recent technology advancements, cellular-based systems offer broadcasters and video professionals the fl exibility to broadcast live events in areas that are well covered by 3G or 4G networks. A portable bonded cellular transmitter, coupled with a high gain cellular antenna array, improves signal resilience and the quality of the live video transmission, providing users with a powerful solution for covering live events, such as a marathon or a cycling race, from a motorcycle. By enabling broadcasters and video professionals to more effectively broadcast news on the go, cellular- based systems dramatically change how the industry covers remote events in a way that couldn’t be imagined even a few years ago. With 3G or 4G networks being deployed widely, we believe that cellular uplink devices are a future- proof solution that allows easy, affordable coverage of breaking news stories or sports events anytime, anywhere. Is it possible to sustain optimal video quality in remote areas? Being able to maintain a high video quality from remote corners of the world can be challenging, but not impossible. It requires mastering three ASK OUR EXPERTS types of technologies. The fi rst is network bandwidth. Broadcasters can get the most amount of bandwidth by bonding together all available networks, such as WiFi, 3G/4G, and satellite, and then adapt the video compression according to those available networks, in real-time. The second technology that comes into play is video compression. Advanced video compression technologies (e.g., H.264 and next-generation standards like HEVC) and pre- and post-processing tools (e.g., fi ltering, video concealment process, etc.) are needed to reduce the required bandwidth for a given video quality level, and improve the quality of experience for viewers. Finally, video contribution is key. The transmission must be robust in order to handle possible errors and packet loss. FEC and packet retransmission are the most common features to implement to improve the transmission reliability.
