Ancillary Data Input/Output:

Closed Caption

SMPTE-334m

SDID=1, SDID=2 not currently supported Service 1 Only

ITU-608 pass-through for 480i59.94 Input/Output processing (all incoming services will pass through, i.e. CC1, CC2, CC3, CC4, T1, T2, T3,T4, and XDS).

ITU-608 to ITU-708 translation for 480i59.94 up-conversions to 720p59.94 & 1080i59.94 (only the primary language from CC1 will be transcoded to DTVCC service S1).

ITU-708 pass-through for HD Input/Output processing for 720p59.94 & 1080i59.94 (all DTVCC services will pass through, the frame rate and checksums will be adjusted as necessary).

ITU-708, Line 21 extraction for down-conversions from 1080i59.94 or 720p59.94 to 480i59.94 (only if the line 21 data is present in the 708 CDP, otherwise the output will contain a clock-run-in with null text).

Vertical Interval Time Code (VITC)

Supports vertical interval timecode (VITC) delay to automatically match the video processing delay

Video Indexing

Supports WSS & RP186

Processing Features:

Video Proc Amp

Video gain – adjustable +/- 6dB, default = 0

Black Level – adjustable +/- 30mV, default = 0

Hue – adjustable -179 to +178, default = 0

Saturation – adjustable +/- 6dB, default = 0

Enhance

Detail Enhance - adjustable 0 to 100, default = 0

Sharpness - adjustable 0 to 100, default = 63
