HDV to HD/SD interface
Miranda’s HD-Bridge DEC+ is a high quality HDV (MPEG-2) decoder
interface with multiple output formats for news gathering, recording,
monitoring, and on-air playout. HD-Bridge DEC+ features two HDV IEEE1394 ports (iLink, Firewire), an ASI input, and a Genlock reference input.
Dual digital video outputs provide either HD-SDI or SDI with embedded
audio and Time Code. One output is a clean feed, and the other features
Time Code burn-in and aspect ratio markers. The interface also provides
composite, SD/HD component video, AES and analog audio, and LTC
outputs. A RS-422 port is available for VTR control, and a built-in cross
converter allows 1080i/720p HD cross-conversion. The interface can also
perform 720p24 HDV to 1080PsF24 HD-SDI conversion for high-end 24p
production, and there is also a 1080i/720p HD to SD downconverter.

Long range HDV news gathering over coax
The HD-Bridge DEC+ can be combined with the ASI-Bridge CAM (see page 308) to create a highly effective long range HDV news gathering system.
This overcomes the short range limits of Firewire cable, and allows more flexibility in the field.
