Background
With the increasing requirements of program production and large-scale activities on production quality, production teams are getting larger and larger, and the requirements of cooperative work are also getting higher and higher. However, the scenario of cooperative use of talkback calls is different from the scenario of conventional cooperative use of talkback calls, and many production sites are extremely inconvenient for director, videographer and performer based on talkback cooperation or single prompt unit cooperation, and a new prompt system is needed to improve the production efficiency of the whole team on programs.
In the conventional technology, the cue operation of the director for the videographer and the performer is completed through a typical single-line direct current cue lamp. This is reasonable in the low-staff, small-scale production phase, but in the era of large-scale events or large-scale program production, this non-networked architecture cannot be implemented and used due to the cross-space distribution of the stations, the large-scale increase of camcorders and performers.
Currently, a common alternative to the traditional single wire dc notification light is achieved by superimposing the notification light command over the transmission cable. And the director performs remote prompt application through the switching station. However, this method can only be implemented by means of an external prompting lamp, and not only cannot sufficiently prompt the shooting personnel, but also can cause the shooting personnel and the performance personnel to generate asynchronous working behaviors, which greatly affects the quality of program production.
In summary, the existing technologies or methods cannot effectively solve the problem that the interactive experience is poor, the prompt feedback is inaccurate, the use space is limited, and the like due to the requirement of cooperative work of the director, the photographer and the performer in the current program making or large-scale activities. The method is a main technical problem which hinders high-quality program production and large-scale activity recording and playing at present.
