Digital signal processing in home entertainment

Abstract

In the last decade or so, audio and video media switched from analog to digital and so did consumer electronics. In this chapter we explore how digital signal processing has affected the creation, distribution, and consumption of digital media in the home. By using "photos", "music", and "video" as the three core media of home entertainment, we explore how advances in digital signal processing, such as audio and video compression schemes, have affected the various steps in the digital photo, music, and video pipelines. The emphasis in this chapter is more on demonstrating how applications in the digital home drive and apply state-of-the art methods for the design and implementation of signal processing systems, rather than describing in detail any of the underlying algorithms or architectures, which we expect to be covered in more detail in other chapters. We also explore how media can be shared in the home, and provide a short review the principles of the DLNA stack. We conclude with a discussion on digital rights management (DRM) and a short overview of the MicrosoftWindows DRM.
