  • FEATURES
    SERIAL DIGITAL COMPONENT AV SYNCHRONIZER

    Equally suited for use in analog, digital or hybrid facilities, the DPS-470 serial digital component synchronizer represents the ideal choice for broadcasters beginning their transition to DTV. Available in video only and audio/video configurations, the DPS-470 provides an ideal bridge from analog video signals, such as satellite and microwave feeds to digital production facilities.

    Four video input and output formats are provided" Serial Component Digital Video (SDI), Component Analog Video (Betacam/MII), Y/C (S-VHS/Hi-8) and Composite Video. 10 bit ITU-R-601 component processing and an adaptive comb filter decoder provide maximum signal transparency. A built in auto-sense TBC circuit provides seamless mode switching between direct color and heterodyne sources, such as camcorders and VCRs. The DPS-470 is more than just a synchronizer. It is also a transcoder and a digital test signal generator. In TSG mode, any one of 32 different 10 bit test patterns can be selected to appear at all four outputs. You can even specify which test patterns are used by the built-in VITS inserter.

    With the addition of a DPS AS-470 four channel audio synchronizer module, the DPS-470 can provide the dual stereo audio and video synchronization in a single rack unit package. The internal audio synchronizer option supports balanced analog, AES/EBU digital and embedded SDI audio I/O. All outputs are active simultaneously, which enables both analog and digital audio devices to be connected at the same time. Incoming stereo audio pairs can be selected from the analog, digital or embedded SDI inputs. All four audio channels dynamically track the internal delay of the video synchronizer whenever auto-track mode is enabled. Up to 16 NTSC fields of fixed delay can also be specified, ensuring proper lip sync regardless of the program source. All audio parameters are controlled from an easy to use front panel menu or from the optional RC-4000 multi-channel remote control panel.

    As broadcasters prepare for DTV, the DPS-470 represents an excellent insurance policy against obsolescence. Use it today as an analog TBC/Synchronizer. Use it tomorrow to interface analog audio and video program sources to serial digital equipment. Think of the DPS-470 as your bridge to a digital future.
