Technologies Vital to High-quality, Reliable Broadcast Operations

Spurred by the commencement of terrestrial digital broadcasting, high-definition broadcasts are now proliferating at a rapid pace. Having moved into high-definition TV while this field was still in its infancy, ASTRODESIGN has more than kept apace with developments and now supports broadcast operations with a host of products ranging from multiprocessors and synthesis systems used for editing high-definition TV programs to LCD monitors used for business applications. As digital technology continues to make more and more inroads into video, the multiplexing of transmission data, conversion of transmission protocols and many other processing tasks now need to be undertaken. As a veritable pioneer in transmission data multiplexing, ASTRODESIGN is also active in the field of protocol conversion technology in ways which will support its growing clientele of internet-based companies as well.
