Evolution of Specifications 2010年民生電子論壇 2010年 24

DVB started with the aim of delivering DTV services to the home via satellite, cable & terrestrial networks. The consumer was (and is) also served by fixed and wireless telecom networks. Fixed Telecom 2010年民生電子論壇 2010年 Broadcast DVB also needed to enable interactive television. Thus the MHP middleware specification was developed. Further enabling i. TV was the development of return channel specifications using the telecom networks as well as satellite, cable and terrestrial networks. Wireless Telecom source: www. dvb. org 25

DVB 2. 0 Broadcast DVB in IP IP in DVB In 2002, the DVB Project launched a new work programme: DVB 2. 0 – looking at the delivery of broadcast services over nontraditional networks. DVB → GSM/UMTS. . . Fixed Telecom 2010年民生電子論壇 2010年 Wireless Telecom source: www. dvb. org 26

DVB 3. 0 Broadcast DVB in IP IP in DVB Late in 2004 DVB agreed on a new work programme for the future – DVB 3. 0 HDTV, HN, CPCM, CBMS, … DVB → GSM/UMTS. . . CBMS Fixed Telecom 2010年民生電子論壇 2010年 Wireless Telecom source: www. dvb. org 27

Areas of Strategic Importance for DVB 3. 0 Convergence of broadcast and mobile services – Wi. Fi, Wi. Max, LTE – 2 G, 3 G, B 3 G, 4 G Convergence of broadcast and IP fixed network services Solutions to support service interoperability across multiple networks and platforms – Content coding – Middleware – Content protection and copy management 2010年民生電子論壇 2010年 28

Digital Convergence really means the freedom for consumers to use any service under any circumstances they choose to Convergence in Contents and Services – Same contents/services can be delivered to different receiving devices via various IP networks – Formats of contents/services are regulated by standards Convergence in Receiving Devices with the same APIs – Various receiving devices can execute the same application with the same middleware APIs – APIs are defined as global standards Convergence in using the same electronic components – Memories, Microprocessors, Middlewares Convergence in IP networks – No matter what physical access networks: x. DSL, FTTH, 3 G/4 G, DVBT/H/T 2, digital cable, satellite, WLAN, Wi. Max, LTE, … 2010年民生電子論壇 2010年 39

Digital Convergence: a whole new way of life Digital convergence is increasing the importance of content and services in the ICT sector. For example, television over IP, (fixed and wireless) is already one of the most successful triple-play and 3 G services. The digital future is interactive. Digital life in media and services is therefore not just about gadgets but about a whole new way of life. 2010年民生電子論壇 2010年 40
