Digital Broadcast Receiver (IRD) / Digital VCR (DVCR) Integrated Circuit

摘要

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a digital broadcasting satellite receiver (IRD) / DVCR integrated circuit, and more particularly, to a display device for displaying analog audio and video data by decoding and descrambling a bit stream transmitted including illegal viewing and copy protection. And a broadcast receiving means for outputting the scrambled digital audio and video data to a recording medium, and recording the scrambled digital audio and video data output from the broadcast receiving means to a recording medium. Digital recording / reproducing means for reproducing and outputting scrambled digital audio and video data to the broadcast receiving means, and interface means for inputting and outputting data between the broadcast receiving means and digital recording / reproducing means are integrated into one system. By simplifying the hardware configuration and external interface, it is easy to control two systems with one controller, and when the function is expanded, it is possible to process by changing the circuit between the internals to limit the limitations due to internal characteristic interface specifications. It is possible to use the input and output related to analog signal processing in common, thereby preventing confusion during use and sharing the existing processing unit for digital functions, thereby making it the most efficient system for digital broadcasting.
