DV-Bridge+ DV to/from Digital Audio, Video and Time Code Codec DV-Bridge+ is the 2nd generation of DV-Bridge codec designed to convert SDI video and AES/EBU audio to and from DV compressed audio/video. DV-Bridge+ integrates VTR control and time code support. It encodes SDI, AES/EBU and time code to the DV format and sends the DV stream on the IEEE-1394 interface. DV-Bridge+ accepts linear time code (LTC) as well as digital vertical interval time code (DVITC). As a decoder it decodes the DV stream arriving on the IEEE-1394 interface and converts it to SDI, AES/EBU and
Features Bi-directional DV to digital audio, video and time code converter Supports Digital Vertical Interval Time Code (DVITC)
time code signals. VTR control such as stop, play, and rewind are received by DV-Bridge+ via IEEE-1394 interface and sent to the VTR over an RS-422 interface. While primarily designed for DV compression, DV-Bridge+ will support DVCPRO compression. Convenient NTSC/PAL (including VITC time code), S-Video and line level analog audio outputs allow simple monitoring or dubbing of the DV signal.
