Course Outline Course brief description Television System Design (block level) IPTV Services and Technologies Public Policy Treatment and Techno- economic aspects in Digital Television communication markets Group assignments

Course brief description Presents commercial Television Systems Covers standards and issues at a basic level Basic concepts of digital processing desirable, but not necessary Covers digital terrestrial, cable and satellite TV, together with IPTV, including IPTV services and technologies. The topics of digital signage systems will be also briefly presented. Addresses issues of public policy treatment and techno- economic aspects in Digital Television communication markets Course evaluation mainly through ‘group assignments’

Convergence From analogue TV and data transmission as distinct parallel paths, to complete disappearance of distinction between data and television! For historical and practical reasons, in this course IPTV is kept as a separate chapter/sector

Television Systems Design Video Standards: signals, formats The capturing system Digital Video Encoding (MPEG series) Digital video transmission and reception (excluding IPTV)

Video Standards: signals, formats Committees on Broadcast Television (at international / regional / national levels) Standards related to broadcast television video only

The capturing system The studio TV signal: SDTV, HTDV other video formats (with relevant data rates) Recommendation CCIR Mbit/s for existing SDTV signals

The capturing system

Digital Video Encoding (MPEG) Data reduction for image and audio compression of the digital video signal: Redundancy reduction and irrelevance reduction (loss of information - role of the human observer) MPEG-1, MPEG-2, MPEG-3, MPEG-4, MPEG-7, MPEG-21 Audio signals to MPEG and Dolby Digital Teletext transmission, subtitles, VBS –video program system for VCR control, EPG – Electronic Program Guide - applications and the role of MHP – Multimedia Home Platform A comparison of digital video (encoding) standards (MPEG-1, MPEG-2, VCD, DVD, M-JPEG and miniDV/DV Picture Quality Analysis of Digital TV signals Recent video compression methods (MPEG-4 AVC Advanced Video Coding, DVB-T2)

DV Transmission and Reception General (modulator / transmitter / demodulator / receiver) Digital Television Signals by Satellite (DVB-S) Broadband Cable Transmission of Digital TV signals (DVB-C) The Terrestrial Transmission of Digital TV signals (DVB-T) Digital Video Broadcast for Handhelds (DVB-H) Other Digital Terrestrial Television Systems

IPTV Services and Technologies Introduction IPTV network distribution technologies Real Time encoding and transportation Broadcasting TV programs over IPTV IPTV consumer devices – IPTVCD and IPTVCD s/w architecture IPTV Conditional access - Digital Rights Management (DRM) systems IPTV at home – Home Media Platform VoD over IP IP based HDTV (high definition TV) Interactive IPTV applications IPTV network administration

IPTV Services and Technologies (cont.) Introduction  Difference between Internet TV and IPTV IPTV network distribution technologies  ‘Last Mile’ Broadband Distribution Network Types  IPTV over: Fiber Access Network/ ADSL Network/ Next Generation Cable TV Networks/ Wireless Networks/ the Internet (streamed video, downloads, p2p  IPTV Backbone Technologies (ATM and SONET/SDH; IP and MPLS; Metro Ethernet)  Network factors associated with deploying IPTV

Real Time encoding and transportation  Introduction to Real-Time Encoding  Compression Methods (MPEG, VC1)  Packetizing and Encapsulating Video Content (7+1 conceptual layers) Broadcasting TV programs over IPTV  Video Components of an End-to-End IPTV System  Streaming IPTV Content  Multicasting across an IPTV Network  Channel Changing  Discovering Channel Program Information  Time-Shifting Multicast IPTV IPTV Services and Technologies (cont.)
