Evertz offers a system to encode and decode General Purpose Inputs (GPI's or Contact Closures) via VITC.
The generator will generate time code in VITC and will encode the status 5 GPI's in the user bits.
This system can be utilized for remote control and remote signaling applications where time code transmission may or may not also be necessary.
The full complement of analog and serial digital generators and decoders are available.
This system can be used for internal plant as well as remote transmission applications.
Integrated with the plant automation system, master control can now extend it's control to remote affiliate sites.
Recent applications have been for providing signaling affiliates/remote broadcast centers on imminent commercial slots and simple machine control.
The encoder allows the insertion of VITC optionally into the first few lines of active video for specific applications requiring signal over a compressed transmission path (MPEG).
GPI Transmission System Products
8010TM SDI Time Code Reader/Generator with Character Inserter
The 8010TM SDI Time Code Master is a full function time code reader/generator system for serial digital video. The 8010TM generates vertical interval timecode and characters directly into the digital video bitstream. GPI Remote Control mode allows the user to pass remote control contact closure information in VITC user bits.
7721DD4-HD+GPI HD/SD-SDI Quad Serial Data De-embedder + GPI Decoder (Digital Decoder)
The 7721DD4-HD+GPI allows the user to decode remote control contact closure information from VITC (SD) or SMPTE 12M-2 ATC (HD) user bits. This feature allows the user to use remote control user bit patterns to control the six GPO relay outputs. At the encoder end the 7721DE4-HD+GPI GPI Encoder module encodes the remote control user bits in VITC or SMPTE 12M-2 ATC.
型号5950 是一个VITC 和LTC 的时间码阅读器、VITC 到LTC 翻译器和全功能的字符插入器，带在屏幕的编成菜单。 这个单元有一个16 位的字母数字显示，用于显示时间码、用户位或操作信息。 5950 读取SMPTE 丢掉或非丢掉帧或EBU 时间码。
