SMPTE, SCTE, EIA and the ATSC have adopted individual technical standards regarding CC implementation. Devices are available to handle all HD and SD formats and frame rates, including the popular 1080 24p format. The Combined Charging System (CCS) is available in two separate versions (not physically compatible) - CCS Combi 1/CCS1 (based on SAE J1772 AC, also called SAE J1772 Combo or AC Type 1) or CCS Combo 2/CCS 2 (based on the European AC Type 2). The AC15C1 has two channels and two inputs. 30C2 is perfect but stupid heavy, maybe even too loud! NUL, BS, FF, and CR are interpreted as they are in ASCII control codes. TV stations haven't completely addressed this DTV captioning issue. EXT1 is used to escape to the 'C2', 'C3', 'G2', and 'G3' tables for the following Opacity is represented by two bits, they represent SOLID=0, FLASH=1, TRANSLUCENT=2, and TRANSPARENT=3. The window size should be scaled based on the font size. fill color, 6 bits. The only difference I can see as far as captioning in the file from Grass Valley and the file made in Premiere is the muxing mode. justify, 2 bits. This specifies in half-seconds how long a caption display or hide effect, such as FADE, and WIPE, should take.
