Crystal Vision helps people transition through a range of technologies, from SD to HD, HD to IP and from IP to IP. The powerful and flexible MARBLE-V1 media processor hardware runs software apps with mixed SDI and IP I/O, making it easy to transition between SDI, ST 2022 and ST 2110. These software apps can work with IP, with SDI or with both IP and SDI at the same time, giving the easiest possible SDI to IP upgrade as well as being perfect for mixed SDI and IP installations. The apps offer functionality such as video delay, colour correction, synchronisation, IP to IP translation (perfect for creating media firewalls) and gateways. The company's feature-packed modular SDI products include chroma keyers, logo keyers, up and down converters, video delays, profanity delays, synchronisers, converters, distribution amplifiers, colour correctors, fail-safe routing switches, embedders and fibre transmitters/receivers.
