An embedded cryptosystem for digital broadcasting
Proceedings of ICUPC 97 - 6th International Conference on Universal Personal Communications, 2002Current day multimedia systems require secure, reliable and fast data transfer. Conventional cryptographic systems attempt to encrypt the entire data directly, thereby requiring significant computation and noise free channels. This makes existing methods less attractive for real time broadcasting.

Antennas for digital radio broadcast
Ninth International Conference on Antennas and Propagation (ICAP), 1995The Digital Radio Broadcast is reviewed briefly and the gain, polarization and other electrical requirements of mobile antennas for direct satellite signal reception, or terrestrial broadcast signals is discussed. Low profile and low cost antenna candidates in the form of multifilar helices and microstrip type radiators are introduced and compared. >

INTEGRATED SECURITY FOR DIGITAL VIDEO BROADCAST
International Conference on Consumer Electronics, 1996As satellite TV becomes more prevalent and the content becomes more valuable, the motivation to pirate its content become greater. Although conditional access and encryption schemes are used in satellite receivers to secure the broadcast content from signal thieves, many of the current systems are vulnerable to attack.

Digital Switch-Over in Broadcasting
2011Digital terrestrial broadcasting systems are currently introduced around the world in many countries. The transition from analogue to digital transmissions is envisaged both for radio and television services. However, in relation to the Digital Dividend the migration of television is of more relevance than switch-over in radio.
