1 XVP-3901 3G/HD/SD Up, Down & Cross Converter with Audio Processor
1.1 Introduction
The XVP-3901 is a highly integrated module designed to synchronize, convert and process 3Gbps, HD and SD
signals into 3G/HD/SD hybrid plants. The card offers a dual multi-rate 3G/HD/SD input and provides simultaneous
3G/HD and SD outputs. Each output path provides independent format, color space and aspect ratio conversion
necessary to maintain a constant signal format at each of the two outputs. With its new higher video quality using
advanced motion adaptive pixel based de-interlacing, the XVP-3901 provides outstanding results regardless of the
formats and conversions made.
A fiber input/output cartridge is offered as an option. This integrates and makes fiber connectivity easier to install and
configure. Once the cartridge is installed, the inputs or outputs are selectable through the control interface. The input
of the card allows you to select between fiber and copper inputs. The outputs offer 3G/HD path on copper and the SD
path on copper, but the fiber module allows you to select between the SD or 3G/HD outputs to be sent to each fiber
connector.
To further improve on-air presentation, the XVP-3901 offers a background keying capability which allows side panels
or letterbox black bars, introduced by aspect ratio conversion, to be filled with video or graphics from the second input.
The ARC function offers fixed presets as well as variable user configurable aspect ratios. The support of AFD (Active
Format description) SMPTE-2016, VLI (Video Line Index) RP-186 and WSS (Wide Screen Signaling) allows the card
to adjust its ARC automatically without any external intervention. It will also re-insert the proper AFD, VLI or WSS on
the output along with other HANC and VANC information. With the integration of the frame sync, incoming feed
signals can be synched to house and have the proper ARC when entering the facility. The XVP-3901 also offers a
video proc-amp with full YUV/RGB level controls and RGB gamut correction.
The XVP-3901 audio capabilities are equally advanced, with processing of up to 32 channels of audio, with automatic
delay to keep lip-sync. It provides shuffling and down-mixing, and options include dynamic processing (limiter,
compressor, and expander), loudness metering, and four AES inputs/outputs for additional flexibility.
The XVP-3901 has 2 on-board sockets for optional modules, including Dolby-E/Digital (AC-3) decoding, upmixing
using Linear Acoustic upMAX™ technology, Dolby-E encoding and Dolby Digital (AC-3) encoding. In addition, the
XVP-3901 features automatic loudness control (ALC) implemented using Linear Acoustics technology.
One RS-422 port is provided for automation control of ARC/User presets and a second port for Dolby Metadata input
and output. 6 GPIs for user presets recall and input selection and 6 GPIs for their corresponding tally outputs.
