See how this modular product fits in a frame:
Typical broadcast and professional media applications require that a number of common processing, conversion and utility functions be performed on signals entering and being generated at various points within the facility:
Typically, multiple products would need to be used to perform the above functions. The 7815VPDA is a single powerful product which supports all of the above functions on two independent paths. This offers exceptional value and density while reducing interwiring, rack space and power requirements. Models are available to support common HD and 3G video formats.
For signal distribution or connection to external elements such as patch panels, re-clocked copies of the input signals are provided on two coax outputs per path. Six coax outputs per path of the processed input signals are also provided. Standard connectors are HD-BNC, while DIN 1.0/2.3 are optional.
As standard features, the 7815VPDA series supports 16 channels of embedded audio, 5.1 to stereo down-mixing (LoRo or LtRt), audio channel shuffling, gain, inversion and mono-mix capabilities. Optional audio processing features include IntelliGain audio loudness control (+IG2 option) and stereo to 5.1 upmix (+UMX2 option).
In addition to coaxial inputs and outputs, the 7815VPDA also offers added I/O via Evertz pluggable SFP modules (ordered separately). Whether the card uses the SFP or coaxial inputs for either processing or distribution path is software selectable on a per path basis. On the output side, in addition to the six fully processed coaxial outputs per path, four outputs per path are available via SFP's. Optical or coaxial type SFP's may be installed (ordered separately) to facilitate alternate coaxial or optical inputs or additional coaxial or optical outputs.
Frame Synchronization and Up/Down/Cross Conversion
With the +UDX2 option, the 7815VPDA series can support frame synchronization and video up/down/cross conversion capabilities. Full AFD, video proc, detail enhancement, RGB based color legalization and ITU Rec. 709 ⇔ 601 color space conversion processes are also included. Audio delay is automatically synchronized with video delay. Additional audio and video delay are also available. CEA 608/708 Closed Caption and timecode information are transferred from input to output performing all HD ⇔ SD data translations and time code recalculations. The 7815VPDA is also capable of generating and embedding timecode via synchronization with NTP.
Ideal for in-house IPTV systems and other monitoring applications, the +SLKE2 option adds the generation of monitoring quality H.264/MPEG2 encoded video (4:2:0) with AAC-LC or HE-AAC-V1/2 encoded audio for streaming over IP. This encoded output can include CEA 708 Closed Captioning and is suitable for PC-based streaming decoder applications, stand-alone IPTV set top box decoders and dedicated modular card-based decoders. The 7815VPDA's video encoding resolution may be set to follow the card's baseband output or may be set to output and hold a different resolution. Common resolutions are supported and range from 240p up to 1080p. A stereo pair of audio is supported, which may be sourced from the dedicated 5.1 to stereo downmixer.
The 7815VPDA is a dual slot card providing up to 14 paths of processing in 3RU when housed in a 7800FR/7800FR-QT frame. These modules are SNMP capable for remote monitoring, control and configuration purposes using VistaLINK® PRO. VistaLINK® PRO control and monitoring is available when modules are used with a 7800FC in slot 1 of the 7800FR frame.
