Digital television (DTV) is the transmission of audio and video
data by digitally processed and multiplexed signals compared to
analog and channel separated signals used by analog television. DTV
represents the most significant evolution in television technology
since color television in the 1950s. The transition from analog to
digital broadcasting began around 2006 with many countries at
various stages of adaptation. DTV provides new features that analog
television cannot support including the need for less bandwidth and
higher image resolution, transmission via several channels
including terrestrial transmitters using antennas, digital cables
and satellites, microwaves and the internet. The book editors have
gathered global experts to provide an overview of the developments
in the field of DTV including fundamentals of human vision; colour
vision; television systems and standards; video signal
fundamentals; error correction for digital signals; audio
compression; MPEG; digital video broadcasting primer and advanced
television systems committee standards (ATSC). The book will be
useful to engineers, researchers and practitioners working in DTV
and video systems and in electronics. It is also a useful reference
for advanced students and researchers in digital television and
broadcasting systems, electrical and electronics engineering and
computer science.
