When not broadcasting in high definition, digital television allows each station to transmit four or more programs simultaneously. Standard definition television (SDTV) multicasting uses a compression technique thats only available with a digital system. SDTV offers higher quality images with stereo sound that far exceed the current analog system. Ultimately, multicasting enables us to share more of our wealth of educational and cultural resources with viewers than ever before.
