Digital Video Concepts, Methods, and Metrics: Quality, Compression,
Performance, and Power Trade-off Analysis is a concise reference
for professionals in a wide range of applications and vocations. It
focuses on giving the reader mastery over the concepts, methods and
metrics of digital video coding, so that readers have sufficient
understanding to choose and tune coding parameters for optimum
results that would suit their particular needs for quality,
compression, speed and power. The practical aspects are many:
Uploading video to the Internet is only the beginning of a trend
where a consumer controls video quality and speed by trading off
various other factors. Open source and proprietary applications
such as video e-mail, private party content generation, editing and
archiving, and cloud asset management would give further control to
the end-user. Digital video is frequently compressed and coded for
easier storage and transmission. This process involves visual
quality loss due to typical data compression techniques and
requires use of high performance computing systems. A careful
balance between the amount of compression, the visual quality loss
and the coding speed is necessary to keep the total system cost
down, while delivering a good user experience for various video
applications. At the same time, power consumption optimizations are
also essential to get the job done on inexpensive consumer
platforms. Trade-offs can be made among these factors, and relevant
considerations are particularly important in resource-constrained
low power devices. To better understand the trade-offs this book
discusses a comprehensive set of engineering principles,
strategies, methods and metrics. It also exposes readers to
approaches on how to differentiate and rank video coding solutions.
