Title:
SYSTEM FOR RECEIVING DIGITAL BROADCASTING AND DEVICE FOR RECEIVING DIGITAL BROADCASTING
Document Type and Number:
WIPO Patent Application WO/2000/038420
Kind Code:
A1
Abstract:
It is judged before recording programming whether analog copy is inhibited or digital copy is inhibited from information on DM_copy_control_description and information on CGMS or M-CGMS. If analog copy is inhibited, analog programmed recording is made nonselectable by using a video mouse; and if digital copy is inhibited, digital programmed recording conforming to the IEEE1394 is made impossible. When digital copy or analog copy is inhibited, a warning to the effect is indicated. Before a programmed recording starts, if the output of an IRD is being recorded by another device, if an MD synchronous recording is being performed, if the recording device is in operation, if no tape or no disk is loaded, if the tape or disk is inhibited from being recorded, if the recording mode of the recording device is an analog recording mode, or if the object is a record inhibited part of a smart file, an indication to the effect is made and the programmed recording is canceled.
