FireBridge™ for HDV




BitBucket for HDV

FireBridge™ for HDV
ASI-BRIDGE CAM BitBucket for HDV Cameras

Real Time, Embedded Linux based, HDV (iLINK, Firewire, and IEEE 1394) to DVB ASI MPEG-2 Transport Stream Converter and Bridge. An "always on" appliance for real time conversion of HDV output from Sony Z1U and JVC HD100U High Definition cameras and JVC DVHS HDM 3000 and HDM 4000 tape recorders to DVB ASI. Features "FrameX" conversion so that 720P from JVC HD100U is at exactly 60 fps.

Miranda HDV to ASI Interface - HDV/IEEE-1394 to MPEG2/ASI Server for use in conjunction with recent Professional HDV cameras from JVC, Sony, and Canon.

The ASI-Bridge CAM is a camera-mounted HDV to ASI converter, which offers direct transmission of HDV news footage, and more effective HDV recording to an MPEG-2 server. The ASI-Bridge CAM can also be combined with the HD-Bridge DEC+ 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. Miranda’s ASI-Bridge CAM interface accepts HDV via an IEEE-1394 connection, and converts it to standard MPEG-2/ASI format. The interface is ideal for HDV news gathering, and can be used to convert HDV directly to ASI without the need for a costly HD MPEG-2 encoder. The ASI-Bridge CAM allows 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 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.
