The NewTek Video Toaster is a combination of hardware and software for the editing and production of NTSC standard-definition video. The plug-in expansion card initially worked with the Amiga 2000 computer and provides a number of BNC connectors on the exposed rear edge that provide connectivity to common analog video sources like VHS VCRs.
Converting video between different numbers of lines, frame rates, and color models in video pictures is a complex technical problem. However, the international exchange of television programming makes standards conversion necessary so that video may be viewed in another nation with a differing standard.
That is a special professional video camera that used a video camera tube would be pointed at a cathode ray tube video monitor. Both the Camera and the monitor could be switched to either NTSC or PAL, to convert both ways. Robert Bosch GmbH's Fernseh Division made a large three rack analog video standards converter, Model NC 56 P 40. These were ...
Stella is an emulator of the Atari 2600 game console, and takes its name from the console's codename. [2] It is open-source, and runs on most major modern platforms including Windows, Mac OS X, and Linux.
This converts 30 frame/second time code to the 29.97 frame/second NTSC standard. Bit 15, the color framing bit, is set to 1 if the time code is synchronized to a (color) video signal. The frame number modulo 2 (for NTSC and SECAM) or modulo 4 (for PAL) should be preserved across cuts in order to avoid phase jumps in the chrominance subcarrier.
For compatibility with material from various regions and sources, ATSC supports the 480i video format used in the NTSC analog system (480 lines, approximately 60 fields or 30 frames per second), 576i formats used in most PAL regions (576 lines, 50 fields or 25 frames per second), and 24 frames-per-second formats used in film.
Use of RSC bypasses the generation of the artefacts that would be introduced in a normal NTSC-to-PAL conversion, and actually reverses the early standards conversion method used to create the NTSC copies. RSC is the result of reverse engineering the method of conversion inherent in the old traditional BBC PAL to NTSC converter.
NTSC color is usually associated with the System M; this combination is sometimes called NTSC II. [7] [8] The only other broadcast television system to use NTSC color was the System J. Brazil used System M with PAL color. Vietnam, Cambodia and Laos used System M with SECAM color - Vietnam later started using PAL in the early 1990s.
