Crystal Vision has released a linear keyer that works with IP (SMPTE ST 2022 and ST 2110 video), with SDI or with both IP and SDI at the same time. The M-KEY can key one externally-generated graphic over a video stream or a matte and is a traditional linear keyer designed for those who use a character generator or graphics PC to provide their key and fill sources. The M-KEY is ideal for a wide range of channel branding and graphic overlay applications, while the mixed IP/SDI I/O means that it can provide a cost-effective solution for those using SDI caption generators to key into an IP feed, with the SDI to IP conversion included in the cost of the keyer.
