LASER DISC VIDEO GAME CONCEPT
Billed as a technology demonstration to reflect the company's intense dedication to
the research and development of exciting and innovative new video game concepts,
Sega Electronics unveiled its latest technological achievement at the recent 1982
AMOA Show in Chicago - a laser disc "video game of the future" ... "Astron Belt".
The major focal point of the show, the cockpit display, received extensive media
coverage as Sega demonstrated state-of-the-art laser disc/computer video game
hardware and software which permits laser disc images to interact with computer
generated graphics in a fantastic gameplay experience. A new stereo sounds system
that utilizes "body-sonics" joins the incredibly realistic scenes for a "total" video
game experience never before encountered.
The high resolution game of the future, "Astron Belt", uses 320,000 picture
elements as opposed to only 60,000 elements for conventional video games. The
video disc, which is similar to a photograph record, holds the game information in
thousands of small indentations that are embedded beneath a clear plastic protective
shell. These indentations are "read" by a small, lower powered laser which then
converts the information into picture and sound. The non-contact system never
touches the disc, thus saving it from wear, meaning that the disc can be played
hundreds of thousands of times without degradation in graphic display quality.
The game concept displayed showed several short action sequences from a
science fiction adventure movie of extremely high quality.
Utilizing the random access capability of the laser disc system, gameplay action
of overwhelming excitement and realism results as the scene changes instantly to
any of a large number of programmed scenes, in accordance with the player's
command or the progress of the game.
Distributor and operator response to the game was outstanding, with many
attendees of the show leaving Sega's booth in a state of incredibility. The schedule
for actual production is tentatively slated for the summer of 1983. No pricing
information is available at this time.
