Abstract :
Recent FCC studies indicate that Americans continue their voracious appetite for television, watching over 8 hours/day per household. In spite of this fixation and a huge market ecosystem, there have been relatively few changes in the underlying core technology since its inception. Now, some 65 years after the FCC released NTSC, television is poised to undergo a major inflection with changes in the information payload, transport, security rights, and rendering devices. In this lecture Bruce covers the transition from analog to digital broadcast and IPTV. Specific topics include: new digital broadcast standards (e.g. ATSC, QAM, DVBT/ H/S/S2/C), security challenges in digital rights management (DRM), new rendering formats, air interface issues, and the convergence of computers, mobile devices, and legacy television.
