AFV SVHS. Digital Processing Systems DPS-470

Below you will find brief information for Digital Component AV Synchronizer DPS-470. The DPS-470 Digital Component AV Synchronizer is a 10-bit video synchronizer, featuring serial digital and analog component, composite, and Y/C input and outputs. It is available in both video-only and audio/video configurations. The DPS-470 provides an ideal bridge between analog video signals, such as satellite and microwave feeds, and a digital production facility. An adaptive comb filter decoder and 10-bit ITU-R-BT.601 component processing provide maximum signal transparency.

Frequently asked questions

The DPS-470 is a 10-bit video synchronizer that provides an ideal bridge between analog video signals and a digital production facility.

The DPS-470 supports serial component digital video (SDI), component analog video (Betacam / MII), S-video (S-VHS / Hi8), and composite video.

The adaptive comb filter decoder helps to provide maximum signal transparency by decoding the signal and processing it in 10-bit ITU-R-BT.601 component processing.

The built-in auto-sense TBC circuit provides seamless mode switching between direct color and heterodyne sources, such as camcorders and VCRs.

In TSG mode, any one of 33 different NTSC (29 PAL) 10-bit test patterns can be selected to appear at all four outputs.

User questions

Patricia O.

What types of Vertical Interval Test Signals (VITS) are available on the DPS-470?

The DPS-470 offers 33 different 10-bit NTSC (and 29 PAL) test patterns. These include various color bar options (full field, five-bar, four-bar, three-bar, two-bar, single-bar), black and white patterns (full field black/white, resolution charts at various percentages, multiburst, square wave, and ramp), and other patterns such as crosshatch, dot pattern, color window, grayscale levels (100%, 75%, 50%, 25%, 10%), color burst, and black burst. PAL patterns are similar but may vary slightly in number.

Jennifer N.

What communication interfaces and protocols are used to control the DPS-470 remotely?

The DPS-470 can be remotely controlled via RS-232, RS-422, or a proprietary DPS Coaxial Network (DCN) port. The communication protocol uses a MIDI compatible format, leveraging the system exclusive feature of the MIDI interface.

Jennifer N.

Can a modern computer achieve remote control of the DPS-470 without access to legacy software packages?

Yes, control can be achieved through custom PC-based remote software by sending the specified MIDI System Exclusive commands.

Patricia W.

What could cause the front panel of the DPS-470 to stop working?

The front panel of the DPS-470 can be rendered inoperative if the KEYLOCK switch on the back panel is in the lock position (down), or if the front panel has been remotely disabled using the KeyLock option from an RC-4000 remote control panel.

Patricia W.

If the front panel keylock is enabled by the RC-4000 remote, can it only be unlocked by the RC-4000? If the remote is not connected, is manual unlocking possible?

If the KeyLock is enabled via the RC-4000 remote, the front panel can be unlocked using the same RC-4000 remote. The manual does not explicitly describe the procedure for unlocking the keylock when the remote is disconnected. However, since the rear panel has a KEYLOCK switch, it may be possible to manually unlock the front panel using this switch, but this is not stated explicitly in the document. Keep in mind that using general assumptions may be unreliable with a specific device, so I suggest you proceed with caution.
