OSAKA, Japan, May 11 /PRNewswire/ -- Panasonic, the brand for which Matsushita Electric Industrial Co., Ltd. is known, today announced that it has begun developing technology to record digital HD (high-definition) images onto SD Memory Cards, following the AVCHD standard for HD digital video cameras. The company is also constructing a new environment for editing and playing back the images.
With the expected adoption of HD broadcasting in many countries and the widespread sales of HD TVs, people will be able to view HD images at home with increasingly enhanced viewing environments. The development of new device technology for the home video market is prompting a major switch in recording media to discs and SD Memory Cards (solid-state memory), which are easier to use and more convenient than tape media.
This new HD video recording technology for SD Memory Cards will conform to the AVCHD standard, which uses a highly efficient compression encoding technology to record 1080i(*1) or 720p(*2) HD images onto 8-cm DVD discs. It will use MPEG-4 AVC/H.264 to compress video files, and Dolby Digital (AC-3) or Linear PCM for audio files. This combination makes it possible to develop HD video cameras that are compact yet deliver high-quality images and sounds.
"Believing that the SD Memory Card is the recording media best suited for video cameras, Panasonic has already released a professional-use HD video camera that uses SD Memory Card technology," said Mr. Akihiro Nakatani, Director of Video Camera Business Unit, Panasonic AVC Networks Company. "Panasonic's efforts to develop the technology to record HD images onto SD Memory Cards and construct a new playback and editing environment, in addition to its establishing the AVCHD standard for 8-cm DVDs, will serve to further stimulate development of products that take advantage of the characteristics of both media."
