PART 6 Production Techniques FIGURE 21.9 Large remote trucks offer more space and additional facilities but are difficult to maneuver within some venues. LIVE TRANSMISSION If an event is being produced for a live audience, the pro- duction's signal must be sent back to a location in order to be broadcast, cablecast, or cybercast. There are a variety of transmission methods: uplink trucks and microwave trucks, fiber optics, and the Internet. 358 Transmission trucks provide units that can be quickly relo- cated and provide broadcast-quality images and sound. Most systems provide a two-way communication link between the unit and base or studio (Figure 21.10). Event Coverage As in every other type of event, directors shooting remote productions must keep the axis of action in mind, placing all cameras on one side of that line (see Figures 18.8, 18.9, and 21.10). FIGURE 21.10 Transmission trucks come in all sizes, depend- ing on what is needed. This unit is a combina- tion satellite uplink and microwave van. Sports Action Sports productions are a bit unique, because the participants can be going all over the venue. Some venues are large (a car racetrack or golf); other venues are very small (a wres- tling match). Events here are categorized by different types of action: horizontal, vertical, and round. HORIZONTAL ACTION Horizontal sports include basketball, soccer, American football, among others. The cameras are placed on a long side of the venue, panning right to left to capture the athletes' action (Figure 21.11). VERTICAL ACTION One vertical sport is tennis. Although it is a sport that takes place on a rectangular venue, like basketball and soccer, the action is difficult to follow by the audience with two players hitting a small ball back and forth. Instead, the cameras are placed behind one of the
