Video Authoring/EditingUntil
now, expensive multi-chip implementations were the only way to create high-quality
video on PCs. The available solutions required expensive boards, special
hardware for playback, and over 10 GB of disk storage for the compressed
output files. The storage is more affordable today, but the hardware expense
still keeps most businesses, professional consumers, and home users locked
out of multimedia video authoring/editing. Few businesses can afford
the time and cost associated with video studios even though their need
for media-savvy presentations is growing. Most businesses, video enthusiasts,
and power PC users are simply waiting....
DIGITAL Semiconductors 21230 -- a
single video codec chip -- lets you exploit these media-hungry markets.
Using the 21230 chip, OEMs can build affordable video authoring/editing
products for consumers. With these products, users can capture and compress
in real time, edit, and add special effects to video on a standard Windows
desktop. Business users might create training videos, point-of-sale kiosks,
or interactive presentations. A real estate office might, for example,
create a virtual tour of homes, with point-and-click videos -- rooms with
a real view! A game manufacturer might use real video instead of 3D graphics.
Camcorder videographers might edit out the "dead" spots, create
professional scene transitions, and add soundtracks to their movies. And
home users might edit their holiday videos and send them to family and
friends. The 21230 lets you bring real multimedia to your end users. Its
technology enables video authoring/editing on Windows desktop systems without
expensive hardware add-ons. It automatically puts video into a PC readable
format, and its superior compression rate allows software playback without
hardware assistance. The chip performs both MPEG-1 IBBP and I frame video
capture and compression at 30 fps, and it supports popular editing packages
from video technology leaders such as Cinax
and Ulead. |
Still Image CaptureStill
images are essential to on-line media, and the ability to share them is
fast becoming part of the context of everyday communication. Already, doctors
in remote areas have illustrated the need by sharing patient X-ray or Ultrasound
images with specialists in major cities. The patient need not (and perhaps
should not) travel, and the capture-to-share capability saves precious
time. Businesses, too, want to add photographic images to their web pages
to generate excitement and to strengthen sales or promotional messages.
Telecommuters want to be able to share selected images from a presentation
with the staff at the main office. And home PC enthusiasts want to create
stills from their camcorder videos to "capture the moment," or
produce digital photo albums that combine old photos and still images from
live video, indexed by subject.
Capturing images from existing video generally
has been costly or difficult because it required specialized hardware.
DIGITAL Semiconductors 21230, a powerful multimedia video codec, lets
OEMs build simple, inexpensive solutions to capture single frames from
any video camera, VCR, or other device that outputs an NTSC or PAL signal.
Consumers can connect a video camera or VCR to their PC, watch the monitor,
and when they see a frame they want, click to capture the frame in computer
memory. Once saved, the image may be manipulated in many ways. The 21230
solutions will allow animated GIFs, morphing, warping, photo touch-up/editing,
and digital greeting cards like those available from Studio

Video ConferencingVideo conferencing
is a cost-effective and convenient way for individuals and groups to "attend"
meetings or collaborate on projects. It combines audio and video in real
time, face-to-face communications that bring people in different locations
together. In the past, the cost of videoconferencing prevented small/home
offices and most consumers from using it to enhance communications. But
today, in solutions that use DIGITAL Semiconductors 21230 codec, OEMs
can deliver these capabilities at a mainstream PC market price. For the
first time, real-time telephony, video, and multipoint data conferencing
can be integrated together into products for everyone. Even home consumers
will be thinking about adding a visual element to communication through
video conferencing "conversations" with family and friends across
the Internet. DIGITAL Semiconductors 21230 implements the H.323 and H.320
standards for video conferencing, and is optimized for business-quality
ISDN and LAN solutions. The 21230 also supports video conferencing over
standard telephone lines (POTS). To provide flexibility in resolution and
formats, the chip supports QCIF (176 X 144) and CIF (352 X 288) resolution
compression from both PAL and NTSC formats. For home use, OEMs may create
solutions that use standard phone lines for direct contact, or that go
through an Internet service provider. In an office setting, the solutions
are likely to use the higher bandwidth LAN networks or ISDN lines, which,
due to higher bit and frame rates, provide larger resolution for crisp,
business-quality video. Telecommuters, too, are sure to be looking for
ISDN based video conferencing solutions to help them communicate via PC
with their colleagues at the office.
The 21230 codec supports the Microsoft
Video for Windows interface, which allows it to work with third-party video conferencing
solutions like VDOnets VDOPhone, Microsofts
NetMeeting, Smith Micros VideoLink,
and White Pines CU-See-Me. |
Business PresentationsIn
major corporations and in small offices alike, todays information workers
are starved for interesting ways to present business information. They
are well aware that the world has become media mad, and theyre anxious
to get attention and to compete.
With DIGITAL Semiconductors 21230 codec,
OEMs can create truly exciting and affordable business presentation packages.
By making the addition of still images and video possible, the 21230 provides
real multimedia in the context of business presentations. Freed from the
constraints of a two-dimensional slide show, your customers will be able
to create innovative approaches that generate interest and excitement --
and results! And the "show" will be far from standard-issue slides.
To exploit the evolving consumer multimedia market, you might include the
image capture and video capabilities currently available from Astound
and Microsoft in your product.
Microsofts PowerPoint now takes MPEG-1 files, so you can click on "hot"
spots to play MPEG videos. Astounds Multimedia Presentation Program also
plays file-based video or animated movies, and it provides a seamless integration
of many types of special effects. Sales trainers might use your product
to include a videotaped sales speech, so students get a chance to see and
hear how the marketing message is "pitched" in
real time. Marketing professionals might create a point-of-sale kiosk show
with interactive elements to emphasize important points. Salespeople might
incorporate video clips from a satisfied customers testimonial to add
power to a business presentation. Imagine the applications! |
Internet Video KitsThe
advent of the Internet has spawned a new breed of small business that focuses
almost exclusively on web page design and web site development. These web
development companies, who have brought leading-edge graphics and multimedia
implementations to their customers, are always on the lookout for new products
and tools that make better use of their money, time, and creative talent.
So to compete in todays media-frenzied market, these designer/developers
need tools that support the latest in multimedia, inexpensively, and that
enable a short concept-to-delivery timeframe.
To keep up with the latest
innovations, web development shops and consultants have had to add lots
of graphics, audio, and video boards to their systems. What if they had
a single board that gave them multiple capabilities? What if their systems
came with such a board and all the right software already installed? With
the 21230 codec, you can build products that enhance applications like
video authoring/editing, still
image capture, and streaming video on
a single board, and your systems can arrive multimedia ready. |
