7714HDC
High Quality Downconverter with Image Enhancement, Low Latency & External AES
The 7714HDC High Quality Down Converter provides high quality down conversion of your high definition (SMPTE 292M) signals to standard definition (SMPTE 259M) signals. The 7714HDC incorporates Evertz proprietary detail enhancement algorithms and gamma correction. The 7714HDC has up to 4 SD Serial Digital outputs or up to 2 composite analog video outputs. Of the 4 outputs, 2 have OSD output. The module supports low processing latency (down to 30 lines) for delay sensitive applications.
The 7714HDC has an external genlock input and allows for phasing of the output video. The 7714HDC accepts all the popular international SMPTE 292M video formats. When the 7714HDC down converts 1080p/23.98sF input video to 525i/59.94 with an embedded 3:2 pulldown, the 3:2 pulldown cadence can be free running or locked to embedded SMPTE 12M-2 time code or an external 6Hz input.
The module accepts 2 groups of embedded audio on the input and re-embeds them into the serial video outputs. As a standard feature, the 7714HDC also accepts 4 discrete unbalanced AES inputs and provides 4 AES outputs with the same audio that is being embedded. It can also reassign audio channels within the groups. The re-embedded audio has the appropriate delay added to compensate for video delay incurred by the conversion process, thus avoiding the need for external de-embedding and re-embedding of audio. An additional audio delay adjustment can also be made for lip sync correction. The 7714HDC also supports down-mixing of surround sound 5.1 PCM audio signals to stereo LtRt/LoRo audio for seamless integration into stereo audio infrastructure.
The 7714HDC has color space conversion from ITU rec. 709 to ITU rec. 601, and will provide various downconverted formats such as 16:9 letterbox, 14:9 letterbox, 13:9 letterbox, 4:3 center crop, and 4:3 anamorphic squeeze. The 7714HDC supports Widescreen Signaling (WSS) on the output to handle various aspect ratios of program material. The 7714HDC can stamp AFD values on the outgoing video signals.
The module also transfers the closed caption and time code information from input to output performing all necessary HD to SD translation and time code recalculations.
The 7714HDC provides card edge LEDs to indicate signal present and audio groups present. The 7714HDC occupies one card slot and can be housed in the 1RU 7701FR frame which holds up to three single or dual slot modules, the 3RU 7800FR frame which has a 15 slot capacity, the portable 3RU 350FR frame which has a 7 slot capacity, or a standalone enclosure which holds a single module.
