******************************************************* * This firmware is for the following products: * * -------------------------------------------- * * 520AD4-HD * ******************************************************* Version 1.6 build 011 fpga 484 (Nov 10, 2005) --------------------------------------------- - Embedder has a fix for HD ACP overwrite and spacing issue - Audio demux is tolerant of 1/2 group SD embedding scheme used by some older Sony boxes, at least 1 version of Sci.Atl., and the original Evertz 7720AE. - Audio Demux should tolerate asynchronous embedding better - corrected misdirected voice-over - corrected blanking contents of META dmx and mux when in SD; it used to blank the line to Y=0x040 and Cr=Cb=0x040. Version 1.5 build 2 fpga 453 (July 19, 2005) --------------------------------------------------------- - audio SD dmx should handle embedding distributions that are not "5 frame exact". Also, expanded tolerance of long periods without embedded packets, especially in vertical areas, in order to work with older embedders. - metadata packets use "Syntax 1" (previous s/w produced "Syntax 0"). The new metadata de-embedder deals with both types automatically. - Support for 720p50 - channel order in SD packets made normal (1,2,3,4) instead of previous (1,3,2,4). It used to cause problems for some de-embedders. - new UTIL/DWMX control for Dolby downmix channel ("DDM" channel) - input metadata is parsed for checksum errors; status or LED will blink if failing Version 1.4 build 3 fpga 391 (June 07, 2005) ---------------------------------------------------------- - corrected VistaLink support Version 1.3 build 236 fpga 365 (January 27, 2005) ----------------------------------------------------------------- ** requires reset command if upgraded from 1.1 or 1.0 ** - fixed bug in embedded HD CUZ bits (still fixed msg) - added SD 525 video delay - added audio delay - added full audio monophonic router/switch - added voice-over mixer - partially tested VistaLink support Version 1.2 build 20 (November 1, 2004) ------------------------------------------------------ ** Must perform a factory reset after upgrading to this version of firmware ** - Can handle both h/w build 1 or 2 - added HD mux/dmx/delay and SD mux/dmx - VANC embedder has a limit of 60 for repeat packets - Added controls: EAUD/GLOK(embedded audio group lock) UTIL/2CHA(stereo vs. Mono channel controls) UTIL/SRC(to enable external AES input SRC) Version 1.0 build 24 (July 29, 2004) ---------------------------------------------- - first release
