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.
Shahriar Akramullah is a recognized expert in digital video engineering. He holds a PhD in Electrical Engineering, and has focused on video quality, compression and speed during his graduate studies. Recently, he has done comprehensive studies of trade-off analysis of visual quality and other factors as part of validation of Intel processor graphics drivers. Before enabling new encoding features, experiments and trade-off evaluations have been done, leading to various optimizations of suitable parameters. On this subject, the author has published several technical papers in various Intel conferences such as DTTC, SWPC, and VPG Tech Summit etc. Furthermore, the author has over 15 years of experience in this field, and has authored several patents and publications in international journals and conferences.
