Courtyard SPGs offer digital diversity

Courtyard Electronics have introduced upgrades to their Digital Master SPG range that allow operation in all digital televsion formats, both at standard and high definition.
The latest enhancements affect both video and audio. New video options include three video outputs that can be individually switched to PAL colour black, NTSC colour black or HD Tri-State Sync, and the ability to have simultaneous SDI Colour Bars and Test signal outputs. The new audio card lifts capabilities to match the latest broadcast requirements. Updates include the addition of two extra channels, so that four channels of audio can be embedded into the SDI outputs if required. Greater versatility is provided by allowing users to embed silence onto the SDI colour black output while simultaneously embedding tone onto the SDI test output. These features complement the existing CY430 capabilities that include Word Clock to precisely lock audio equipment.
These enhancements not only minimise necessary SPG equipment but also aid multi-format operations such as conversion, where all sources are locked to the same crystal. Having all reference signals derived from the same frequency source is the ideal sync solution. It simplifies system engineering and virtually eliminates the possibility of problems caused by sync slips between separate references.
