A system for playing a selected one of multiple audio tracks recorded in synchronized fashion with a motion picture on an optical disk. The optical disk has encoded on it a mixing master music and effects (“M&E”) track, or a switching master M&E track. Individual audio tracks are provided for language-specific versions of the same motion picture, but these tracks have data recorded in them only where there is dialog. In this way, for many a motion picture, all tracks but masters will have data recorded for well less than half of the running time of the motion picture. When a mixing master is used, it is mixed with a language-specific track when the latter has dialog; the mixing master contains no dialog. If a switching master is used, it may contain dialog recorded with the M&E; when a language-specific track has dialog recorded in it, it also contains M&E and the track is played to the exclusion of the switching master.
A data stream containing data representative of frames of a motion picture in the form of successive data blocks, said data blocks being preceded by data indicative of the aspect ratio of the picture frames represented by said data blocks, said data blocks containing pan scan data together with picture frame data, each item of pan scan data being indicative of a portion of an overall frame, with different items of pan scan data being indicative of different portions of an overall frame.
The data stream contained on or derived from an optical disk, said data stream representing frames of a motion picture and having a data structure comprising successive data blocks preceded by data indicative of the aspect ratio of the picture frames represented by said data blocks, said data blocks containing pan scan data together with picture from data, each item of pan scan data being indicative of a portion of an overall frame, with different items of pan scan data being indicative of different portions of an overall frame.
A method for controlling operation of a player that processes a data stream, the data stream containing digital data representative of picture information having a base aspect ratio and including a code inactive of said base aspect ratio, the method comprising the steps of having the player normally represent a default aspect ratio but allowing a user to select one of several aspect ratios thereby to change the represented aspect ratio from the default to the selected aspect ratio;
A method for generating a video signal in one of multiple aspect ratios from processing of a data stream which represents an image program in only one aspect ratio, said data stream including a code indicative of the represented aspect ratio, comprising the steps of processing the data in said data stream to derive a signal representative of the image program represented thereby, normally identifying a default aspect ratio but allowing a user to select one of said multiple aspect ratios thereby to change the identified aspect ratio from the default to a selected aspect ratio, generating a video signal from the signal derived from processing of the data in said data stream in an aspect ratio which is a function of both the aspect ratio represented by said code and the identified aspect ratio, and, responsive to the aspect ratio indicated by said code and the identified aspect ratio being insufficient to determine the aspect ratio of said video signal, providing the user with a choice of aspect ratios each consistent with both the aspect ratio represented by said code and the identified aspect ratio.
A method for generating a video signal in one of multiple aspect ratios from processing of a data stream which represents an image program in only one aspect ratio, characterized by said data stream including a code indicative of the represented aspect ratio and a code indicative of the availability in said data stream of pan scan information, comprising the steps of processing said data stream to derive a signal representative of the image program represented thereby, selecting one of said multiple aspect ratios, generating a video signal from the signal derived from processing of said data stream in an aspect ratio which is a function of both the selected aspect ratio and the aspect ratio indicated by said code, and operating on pan scan information contained in said data stream and for controlling in accordance therewith the signal derived from processing of said data stream.
A method for generating a video signal in one of multiple aspect ratios from processing of a bit stream which represents an image program in only one aspect ratio, said bit stream including a code indicative of the represented aspect ratio, comprising the steps of processing said bit stream to derive a signal representative of the image program represented thereby, selecting one of said multiple aspect ratios, and generating a video signal from the signal derived from processing said bit stream in an aspect ratio which is a function of both the selected aspect ratio and the aspect ratio indicated by said code, and wherein said one aspect ratio is 16:9 or 4:3, and said multiple aspect ratios include 16:9, center cut 4:3, pan scan 4:3, and letter box.
A set of stored data embodied in a data stream containing data representative of frames of a motion picture in the form of successive data blocks, and data indicative of the aspect ratio of the picture frames represented by said data blocks, said data blocks containing pan scan data together with picture frame data, each item of pan scan data being indicative of a portion of an overall frame, with different items of pan scan data being indicative of different portions of an overall frame.
A method for controlling operation of a system that processes a data set, the data set containing digital data representative of picture information having a base aspect ratio and including a code indicative of said base aspect ratio, the method comprising the steps of having the system normally represent a default aspect ratio but allowing a user to select one of several aspect ratios thereby to change the represented aspect ratio from the default to the selected aspect ratio;
