XVP-1801 HD/SD Up/Down/Cross Converter with AFD
The Densité Series XVP-1801 interface is the most advanced HD/SD modular
interface in Miranda’s range, and offers an unmatched combination of high
quality processing and sophisticated features. This single card processor
and Up/Down/Cross converter offers AFD support and background keying,
with 16 channel embedded audio processing. The superior conversion
quality of the XVP at both 50 and 59.94Hz stems from multiple technologies,
including advanced motion adaptive de-interlacing and anti-ringing.
To ensure that up/down converted television is presented in the correct
aspect ratio when aired, the XVP module supports AFD (Active Format
Description) SMPTE-2016. This provides automatic aspect ratio control
using embedded control commands, and this prevents on-air aspect ratio
errors such as the postage stamp effect (see page 78). The ARC function
offers fixed presets as well as variable user configurable aspect ratios. In
addition to AFD, the XVP also supports VLI (Video line index) RP-186 and
WSS, which allows the card to adjust its ARC automatically without any
external intervention. The module re-inserts the correct AFD, VLI or WSS
on the output, along with other HANC and VANC information. With the
integration of a frame sync, incoming feed signals can be synched to house,
and video/audio levels adjusted using a proc and color correction, when
entering the facility. A RS-232/422 port is provided for automation control
of ARC presets, and GPIs are also available for user presets.
To further improve on-air presentation, the XVP offers a background keying
capability which allows side panels or letterbox black bars, introduced by
upconversion or downconversion, to be filled with video or graphics.
The XVP-1801 will pass and delay automatically all 16 channels (4 groups)
of embedded audio to keep lip-synch. Full audio processing, shuffling,
downmixing and 4 AES in and 4 AES out channels, are available as an
option. A higher level of audio capabilities are provided by a range of
audio processor companion cards. When connected to a DAP-1781, UAP-
1781/3 or an AAP-1741, the XVP-1801 gains additional AES or Analog
audio channels while still maintaining lip-synch. Depending on the audio
processor selected, these boards also offer Dolby E or Dolby Digital (AC-
3) for encoding or decoding, up-mixing from 2.0 to 5.1, and full dynamic
processing (limiter, compressor, and expander).
