Miranda Shows Multiple New HDV Interfaces (19/5/2005)

Miranda is showing multiple new HDV interfaces in its HDV Zone at NAB, including the HD-Bridge DEC+ HDV to HD/SD converter, the ASI-Bridge CAM HDV to ASI interface, the ADC-800 CAM A to D converter, and the AMX-800 CAM embedder. These compact converters represent the widest range of HDV interfaces, and they are highly adapted for multiple applications.

The HD-Bridge DEC+ is a high quality HDV (MPEG2) decoder interface with multiple output formats for news gathering, recording, monitoring, and on-air playout. HD-Bridge DEC+ features two HDV IEEE-1394 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 HD-Bridge DEC+ 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. A lower cost version, called HD-Bridge DEC, is identical except that it does not include the ASI and Genlock inputs.

The ASI-Bridge CAM is a camera-mounted HDV to ASI converter, which is ideal for HDV news gathering, and for direct MPEG-2 recording on a server for cost effective preparation of dailies. The use of ASI cabling from the camera means the dailies recording device can be located further away from the camera.

The ASI-Bridge CAM accepts HDV via an IEEE-1394 connection, and converts it to standard MPEG-2/ASI format. This compact interface mounts discretely between an HDV camcorder and a tripod, and accepts power from the camera battery or from a dedicated in-line power supply. The ASI-Bridge CAM can also be combined with the HD-Bridge DEC+ to create a highly effective long range HDV news gathering system, which overcomes the short range limits of Firewire cable and allows more flexibility in the field.

Miranda's ADC-800 CAM is a compact, camera mounted A to D interface for live HD digital monitoring and recording from an HDV camcorder. This is achieved by converting the EE uncompressed component analog output to HD-SDI, with embedded left/right audio and Time Code. This path overcomes the processing delay inherent with the MPEG2 Long GOP structure, which makes it inappropriate to use the HDV stream for live monitoring. This process also avoids having to use many cables for recording. The ADC-800 CAM provides a separate on-screen display output with markers, Time Code burn-in, and VU meters.

The compact, camera mounted AMX-800 CAM interface is an HD/SD 4 analog audio and Time Code embedder, designed especially for the Canon XL H1 HDV camcorder. The interface can also be used as a stand-alone SD/HD embedder.
