Abstract
A video stream decoder include: a demultiplexing unit for demultiplexing a video stream containing at least one or more object encoded visual or audio data and one or more scene descriptions which express scene contents by object encoded data; a decoder unit for decoding the object encoded visual data; a decoder unit for decoding the object encoded audio data; a visual synthesizing unit for synthesizing images corresponding to the object encoded visual data; an audio synthesizing unit for synthesizing sounds corresponding to the object encoded audio data; an analyzing unit for analyzing each scene description; a selector for selecting one of at least two or more scene descriptions contained in the video stream.
Claims17
A video stream decoder, comprising:
- demultiplexing means for demultiplexing a video stream containing at least one or more object encoded visual or audio data and one or more scene descriptions which express scene contents by object encoded data;
- decoding means for decoding the object encoded visual or audio data;
- analyzing means for analyzing each scene description;
- and
- selecting means for selecting one of the scene descriptions if the video stream contains at least two or more scenes;
- user input means to be used for a user to input information, wherein said selecting means selects a scene description in accordance with an input from said user input means.
A video stream decoder, comprising:
- demultiplexing means for demultiplexing a video stream containing at least one or more object encoded visual or audio data and one or more scene descriptions which express scene contents by object encoded data;
- decoding means for decoding the object encoded visual or audio data;
- analyzing means for analyzing each scene description;
- and
- selecting means for selecting one of the scene descriptions if the video stream contains at least two or more scenes;
- communications means for communicating with an information transmission apparatus to receive the object encoded visual or audio data.
A video stream decoder, comprising:
- demultiplexing means for demultiplexing a video stream containing at least one or more object encoded visual or audio data and one or more scene descriptions which express scene contents by object encoded data;
- decoding means for decoding the object encoded visual or audio data;
- and
- analyzing means for analyzing each scene description;
- selecting means for selecting one of the scene descriptions if the video stream contains at least two or more scenes;
- wherein at least two scene descriptions include a first scene description for not decoding the object encoded visual or audio data and a second scene description for decoding the object encoded visual or audio data, and said selecting means selects one of the first and second scene descriptions.
A video stream decoding method comprising the steps of:
- demultiplexing means for demultiplexing a video stream containing at least one or more object encoded visual or audio data and one or more scene descriptions which express scene contents by object encoded data;
- selecting either a first scene description for not decoding the object encoded visual or audio data of the video stream or a second scene description for decoding the object encoded visual or audio data;
- and
- decoding the object encoded visual or audio data in accordance with the selected second scene description.
A program product capable of being read with a computer, the program product making the computer realize the steps of:
- demultiplexing means for demultiplexing a video stream containing at least one or more object encoded visual or audio data and one or more scene descriptions which express scene contents by object encoded data;
- analyzing each scene description and selecting either a first scene description for not decoding the object encoded visual or audio data of the video stream or a second scene description for decoding the object encoded visual or audio data in accordance with an analysis result and an input by a user using the computer;
- and
- decoding the object encoded visual or audio data in accordance with the selected second scene description.
A program installed in a computer for execution therein including a computer-readable plurality code corresponding to the steps of:
- demultiplexing means for demultiplexing a video stream containing at least one or more object encoded visual or audio data and one or more scene descriptions which express scene contents by object encoded data;
- analyzing each scene description and selecting either a first scene description for not decoding the object encoded visual or audio data of the video stream or a second scene description for decoding the object encoded visual or audio data in accordance with an analysis result and an input by a user using the computer;
- and
- decoding the object encoded visual or audio data in accordance with the selected second scene description.
