Video Distribution System
Many meetinghouses in the U.S. and Canada are equipped with video distribution systems. These systems are the means of distributing video signals throughout the meetinghouse. System designs vary with the age of the system and the needs of the units when the systems were installed.
The newest systems are controlled via the video switcher in the video rack. This switcher allows the user to select which video input is distributed to the building and, for stake centers, to the webcast transmitter (Teradek). Inputs are clearly labeled. These designs do not allow for different video sources to be sent to different locations.
Older systems use RF modulators. These systems require the user to select which video signal is viewed at each location by selecting the appropriate TV channel from the connected TV system.
Video systems are generally replaced every 20 to 25 years along with the meetinghouse sound systems. Exact timing is determined by local considerations, including cost and need. Systems are not replaced simply to update an existing system’s functionality.
Due to the demand for webcast in meetinghouses and the high cost of replacing existing systems with new webcast-capable systems, many RF-based systems have been retrofitted with an AVDH-1 or AVDH-2 product.
