Title:
放送番組のコンテント制御
Document Type and Number:
Japanese Patent JP4448273
Kind Code:
B2
Abstract:
The invention allows a personal video recorder to store and selectively play a broadcast program whose scenes are tagged with content codes. The personal video recorder utilizes user preferences, derived from user inputs. When a program is broadcast and stored on hard disks in compressed form, simultaneously an associated file is generated and stored. This file characterizes individual scenes in accordance with the respective tagged codes, derived from VBI data, code blocks in a digital transmission, etc. The file includes data from which the starting and ending points of individual scenes can be determined, with the ending point of a scene being conveniently determined by the broadcast receipt of the start of the next scene with a new tagged code. The system consults user preferences and the previously generated file during play of a stored program to determine scenes to be skipped and the starting point of any scene that is to follow a scene that is to be skipped. Viewing of a program cannot begin with its broadcast because if it does, then whenever a scene is to be skipped the following scene will not yet have been received. If seamless play (no gaps between scenes) is desired, then there is need to delay the start of viewing sufficiently for the recording of any scene that follows a scene to be skipped to have already been started before that scene is required for play.
