The 7812HDC-HD and 7812HDC-AES8-HD are Broadcast Quality Down Converters that down convert common HD/SMPTE ST 292-1 to common SD/SMPTE ST 259 video signals. -3G versions add support for common 3G/SMPTE ST 424 video signals. These modules support frame synchronization and external genlock inputs (card and frame reference) for video timing adjustments.
The 7812HDC series incorporates Mosquito Noise Reduction (MNR) and Block Artifact Reduction (BAR) in addition to motion adaptive spatial-temporal (3D) noise reduction. The 7812HDC series also incorporates new de-interlacing technologies for superior resolution and artifact reduction.
The 7812HDC series supports broadcast quality scaling and offers both standard and user defined ARC modes. AFD (SMPTE ST 2016) based steering of ARC modes and stamping AFD codes is fully supported. Transitions between AFD modes are frame accurate/glitch free. With the +F option, signals applied to PGM B IN can be keyed into image side panels. FILL inputs are frame synchronized so that pre-timing of FILL inputs is not required. With the +CF2G option, static or animated side panels can be stored locally and keyed into image side-panels.
Full broadcast quality color correction and detail enhancement processors are integrated in the 7812HDC series. RGB based color legalization is also supported. ITU Rec. 709 ⇒ 601 color space conversions are performed as needed.
The 7812HDC series supports 16 channels of embedded audio with audio delay automatically matching video delay. Additional audio delay is available. Full audio proc is supported including per channel audio gain, channel swapping and inversion controls. Surround sound to stereo (Lt/Rt or LoRo) down-mixing is supported.
On -AES8 variants of the 7812HDC series, 8x discrete AES inputs and outputs are supported in addition to advanced audio processes like stereo to 5.1 up-mixing (+UMX), Dolby® E/AC-3 Decoding (+DD), Dolby® E Encoding (+DEE), Dolby® AC3 Encoding (+AC3E) and IntelliGain Loudness Management (+IG). Any two Dolby® encode or decode functions may be integrated into a single card including dual decoders or dual encoders.
These modules transfer closed caption and time information from input to output performing all HD ⇒ SD data translations and time code re-calculations. SFP based fiber inputs and outputs can be supplied with the -F variations. (SFP modules ordered as separate accessories)
