Design of Dual-decoding DVB Set-top Box and the Implementation of Conditional Access System
Article Abstract: As a signal receiving terminal, set-top box is a strategic platform on which the digital cable TV can be realized. Two schemes, based on STi7200 chip and dual-core STi5518, are proposed and compared to each other in this paper to realize multiple signals receiving for different televisions in the family. The implementa- tion of conditional access system in dual signal decoding process is analyzed, which is the key technology of this novel DVB Set-top Box.
