Roland VC-1-DL - FS Delay
Roland's new video converters address the demand for high-quality, lossless video and audio converters for live/post production as well as installed systems. They include the Roland VC-1-HS (HDMI to SDI), VC-1-SH (SDI to HDMI), VC-1-DL (Bi-directional SDI/HDMI with audio/video delay and frame sync) and VC-1-SC (Up/Down/Cross Scan converterto/from SDI/HDMI).
The VC-1 Video Converter series
The VC-1 Video Converter series provides uncompromising picture quality by maintaining the video characteristics of the original signal with rich-blacks and super-whites. There are no interlacing artifacts or other conversion or signal errors sometimes found with other video converters. The VC-1 series also features an on-board re-clocker to compensate for attenuation of SDI signals carried over long distances. The VC-1 series also supports both level A and B 3G-SDI, letting you connect a variety of higher quality SDI sources.
The VC-1 series is HDCP compliant allowing you to convert or pass-through HDCP signals with the exception of any SDI output. The VC-1-DL additionally enables the HDCP signal to be delayed. Selectable audio embedding and de-embedding lets you route different audio sources to or from video devices. Digital AES/EBU input and output signals are supporting ensuring high-quality audio signals can be maintained through the signal flow.
Roland VC-1-DL
In live production as you add more video components to a signal flow, latency is introduced. The VC-1-DL converter not only allows bidirectional conversion of SDI/HDMI but it also provides frame sync and delay adjustment of up to 9 fields (4.5 frames) for audio and video independently. This is helpful when keeping various types of cameras in sync as well as ensuring a projector stays in sync with an LED wall. In this way it is an indispensable tool live production, broadcast and recording applications.
