7713HDC
HD Downconverter & Distribution Amplifier
The 7713HDC is a reclocking high definition serial digital video distribution amplifier and a high quality downconverter for 1.5Gb/s HDTV signals. The 7713HDC incorporates Evertz proprietary detail enhancement algorithms and gamma correction. It can also function as a monitoring distribution amplifier for standard definition 270Mb/s signals. The 7713HDC provides 4 reclocked DA outputs and 3 downconverted SDI or composite analog NTSC/PAL outputs (selectable).
The 7713HDC accepts all the popular international SMPTE 292M video formats. When the 7713HDC 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 7713HDC also de-embeds two groups of audio and re-embeds the audio on the SDI output in time with the video. 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.
The 7713HDC has color space conversion from ITU rec. 709 to ITU rec. 601, and will provide various down converted formats such as 16:9 letterbox, 14:9 letterbox, 13:9 letterbox, 4:3 center crop, and 4:3 anamorphic squeeze.
The module also transfers the closed caption and timecode information from input to output performing all necessary HD to SD translation and time code recalculations.
The 7713HDC 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.
