Abstract
An apparatus of the present invention has a storage that stores a data stream in which identification data with identification information for retrieval incorporated therein is multiplexed along with video data and audio data, a plurality of demultiplexing sections that demultiplex the stored data stream to the video data, audio data and identification data, a video data and audio data decoding section that decodes the video data and audio data, each demultiplexed, to reproduce, and a retrieval section that retrieves specific video data and specific audio data based on the demultiplexed identification data, and thus executes the video reproduction and retrieval in parallel.
Claims9
A video storage and retrieval apparatus, comprising:
- a storage section configured to store a data stream in which identification data with identification information for retrieval incorporated therein is multiplexed along with video data and audio data;
- a first demultiplexing section configured to demultiplex said data stream stored in said storage device and to output video data and audio data;
- a second demultiplexing section configured to demultiplex said data stream and output said identification information;
- a decoding section configured to decode and reproduce demultiplexed video data and audio data;
- and
- a retrieval section configured to retrieve specific video data and specific audio data based on demultiplexed identification data,
- wherein, when a reproduction request and a retrieval request overlap in time, said second demultiplexing section executes a demultiplexing operation to extract the identification data for retrieval from said data stream and said first demultiplexing section executes a demultiplexing operation to extract the video data and the audio data each for reproduction from said data stream in parallel.
A video storage and retrieval method, comprising:
- storing a data stream in which identification data with identification information for retrieval incorporated therein is multiplexed along with video data and audio data;
- reading the stored data stream as an object to be reproduced and the data stream as an object to be retrieved when a reproduction request and a retrieval request overlap in time;
- demultiplexing the stored data stream with a first demultiplexer to extract video data and audio data;
- demultiplexing the stored data stream with a second demultiplexer to extract identification information;
- and
- decoding and reproducing demultiplexed video data and the audio data while retrieving specific video data and specific audio data based on the identification data demultiplexed from the data stream as the object to be retrieved, the extraction of the video data and audio data and the extraction of the identification information occurring in parallel.
