Abstract
A method and apparatus for continuous audio documents for visual presentations without interruptions are provided. An audio input (126) is used to visually describe an electronic document or image displayed upon a display device (106). The video part of the slide show is recorded, and then placeholders are used for the audio data so that audio data can be later recorded to a disc at the locations of the placeholders.
Claims17
A method for generating a multimedia presentation for a playback, the method comprising the steps of:
- (a) recording a stream of video packets in a memory device (122);
- (b) recording audio placeholders at locations where real audio packets will be stored;
- and,
- (c) retrieving and adding the real audio packets to appropriate locations of the audio placeholders for a subsequent playback.
An apparatus for generating a multimedia presentation for a playback, comprising:
- means for storing a stream of video packets in a memory device (122);
- means for recording audio placeholders at locations where real audio packets will be stored;
- and,
- means for retrieving and adding the real audio packets to the locations of the audio placeholders for a subsequent playback.
A method for generating a multimedia presentation for a playback, the method comprising the steps of:
- (a) selecting picture data comprising video packets having a pre-specified duration to be recorded;
- (b) encoding and recording the picture data.
- (c) recording audio placeholders at locations where real audio packets will be stored;
- (d) multiplexing and storing the audio placeholders instead of real audio packets;
- and,
- (e) retrieving and adding the real audio packets to appropriate locations of the audio placeholders to allow playback as a slideshow.
A digital recording device for generating a continuous audio playback during a presentation of a slideshow, comprising:
- a video device (108) for encoding and decoding the video associated with the slideshow;
- an audio device (104) for recording the continuous audio;
- a storage device (122) for storing video packets and audio packets for a subsequent playback;
- a processor (102) coupled to the storage device (122), the video device (108), and audio device (104) for controlling operation of the digital recording device, the processor (102) functioning in a first phase such that in response to a user input, the video packets and audio placeholders where the audio packets will be stored in a second phase are recorded, the processor (102) further functioning in the second phase such that the locations of the audio placeholders are retrieved to add the audio data to appropriate locations to enable the presentation of the slideshow.
