Why Canopus chooses not to use the C-Cube DVxpress chip on its new products By Hiro Yamada, President and CEO of Canopus Corporation From the outset, Canopus made the decision to develop a complete and original hardware design to satisfy our customer's needs and expectations. Our engineers found that the C-Cube DVxpress chip produced a number of limitations. No real-time DV output capabilities when adding transitions and titles. Limited real-time functions when outputting to analog.
MPEG output is poor - captured picture is always too soft, even at high bit rate.
Compression of audio in the MPEG format is not in real-time. Canopus decided to work with companies like Sony, Panasonic, Canon and Sharp, which produced chip technology specifically made for video. The C-Cube chip DVxpress was developed for MPEG encoding and decoding, not for DV video. Canopus only designs products and technology that we know best. All of the hardware and software technology is developed in-house.
