a digital video camera that allows the taping of sharp, crystal-clear images in smaller files."This model is not found elsewhere in the world except in Japan," said Randall Chiu, vice president of sales and marketing of AVIT.
The DV is special in that it uses the MPEG-4 standard, instead of MPEG-2 used by mainstream models.
MPEG-4 is a more advanced compression technologuy than MPEG-2 and records four times more video content than MPEG-2 does.
"In other words, four minutes worth of MPEG-4 video takes up the same space as one minute worth of MPEG-2 video," Chiu said.
In Chiu's words, the DV's use of MPEG-4 has two major benefits. First, the video content may be transferred in shorter time over the Internet in a broadband environment. Second, the video content takes up less space.
The DV uses the Secure Digital (SD) memory card instead of hard drive or digital video cassettes. This has several advantages, Chiu said.
"Compared to traditional hard drive, SD is less vulnerable to the force of impact when it hits the ground," Chiu said. "Also, SD allows easier transfer of files to the PC, as oppposed to devices that use digital video cassettes."
SD has storage size from 1GB to 4GB and may see its memory expanded to 8GB or even 32GB in the future. SD, along with other Flash-based memory cards such as CompactFlash, SmartMedia and the Memory Stick, is found in an increasing number of consumer electronic devices.
The camera may record up to 180 minutes of contents with a 4GB SD card, and it has a battery life of approximately two hours, Chiu said.
The DV has fixed zoom of 3X, yet it may be attached to a high magnification spotting scope of 25X, 30X or 36X to allow for zoom of up to 108X. "This is especially ideal for certain professionals such as police officers or photojournalists," Chiu said.
The product is distributed to mostly Europe and the United States. "Users have expressed strong enthusiasm for the product," Chiu said.
