This allows the selection of either a 50 or 60 Hz output regardless of 720/1080 input frame rate. Details: - Larger (standard) output when 720p is input - Reduced interlace artifacts In addition to the conversions from before, there is now selectable via DIP switch 6: 50Hz to PAL conversion 60Hz to NTSC conversion New dip switch settings DIP 6: UP is NTSC (60Hz) output, DN = PAL (50Hz) output - see chart below ------------------------------------------------- Input DIP 6 ON (DOWN) DIP 6 OFF (UP) ------------------------------------------------- 1080i/60 625i/50 525i/60 1080i/59.94 INVALID OUTPUT 525i/59.94 (NTSC) 1080i/50 625i/50 525i/59.94 (NTSC) 1080p/25sF 625i/50 525i/60 1080p/24sF 625i/50 525i/60 1080p/23.98sF INVALID OUTPUT 525i/59.94 (NTSC) 720p/60 625i/50 525i/60 720p/59.94 INVALID OUTPUT 525i/59.94 (NTSC) ------------------------------------------------- - Support of 720p side cut ARC function Version 3.0 build 10 - (June 19, 2002) ------------------------------------- - fix for minor intermittent boot-up issue Version 3.0 build 5 - (January 4, 2002) --------------------------------------- - 480p support added DIP 8: DOWN means input is interpreted as 480p UP means input is treated as 1080i NTSC Setup pedastal DIP 5: DOWN turns off NTSC pedastal in NTSC UP leaves it on in NTSC - Color NTSC support for 60Hz based HD inputs added Because DIP's 8 and 5 are repurposed the MD now: 1) Is always in auto input standard detect mode 2) Always has HD to SD color space corrections 3) Standard selection DIP 3 and 4 no longer have any function Note: this code works on all revisions of PCBs Version 2.0 build 6 - (May 16, 2000) ------------------------------------ - supports 1080p/24sF to PAL output conversion ** Note: 1080p/24sF support only available on special order 7710MD-24sF down converter ** Version 1.9 build 6 - (April 28, 2000) -------------------------------------- - removes 2 frames of delay in non-pulldown modes. Version 1.8 build 107 - (April 10, 2000) ---------------------------------------- - for mbus crash recovery enhancement on units with R496 installed. This version will run without any hardware mods. The addition of the resistor has no effect on old software. Version 1.8 build 96 - (April 8, 2000) -------------------------------------- - this code does not drop fields, the fields are always in correct alignment; including the 3:2 pulldown - the downconverted image is clearer than in some past versions - there are no double lines in any of the formats - the green line that sometimes appeared near the bottom of the image in some of the older version should never appear in this one - all of the functionality is included (colour space conversion, automatic standard detection, 1080i/50, and 1080p/24sF) ** Note: 1080p/24sF support only available on special order 7710MD-24sF down converter ** Version 1.7 build 8 - (March 3, 2000) ------------------------------------- - fixed 1080p/24sF field flip ** Note: 1080p/24sF support only available on special order 7710MD-24sF down converter ** Version 1.7 build 1 - (March 3, 2000) ------------------------------------- - fixes the 4:3 squeeze and side-cut problem where single horizontal lines can become 2 lines - also fixes a problem where the phase of the output with respect to the input can drift after losing input in 3:2 pulldown mode Version 1.6 build 1 - (March 24, 2000) -------------------------------------- - fixes a potential problem when there is no input or a corrupt input present Version 1.5 build 2 - (March 14, 2000) -------------------------------------- - this code corrects a potential problem where, if the output format dip switches are set in the state reserved for future use, then the video standard is changed, the video could be corrupted Version 1.4 build 393 - (March 3, 2000) --------------------------------------- - added 1080i/50 and 1080p/24sF support ** Note: 1080p/24sF support only available on special order 7710MD-24sF down converter ** - color-space correction (dip switch 8 on=csc enabled / off=csc disabled) - automatic standard detection Version 1.3 build 3 - (February 7, 2000) ---------------------------------------- Version 1.3 build 2 - (July 13, 1999) ------------------------------------- Version 1.2 build 2 - (June 29, 1999) ------------------------------------- Version 1.1 build 7 - (June 16, 1999) ------------------------------------- Version 1.0 build 409 - (May 13, 1999) -------------------------------------- - first release ** 1080p/24sF support is only available on down converters that where ordered with the 7710MD-24sF option. This option is only installable at the factory **
