ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a video/audio-creating method and a video/audio-creating system. (In this document, “video/audio” means “video and/or audio”.)
2. Description of the Related Art
Recently, video cameras and personal computers for home-use (PCs) have been widely used, and an increasing number of people perform Internet-based communication using video/audio. A representative example of the types of media used for communication is electronic mail. Recently, electronic mail frequently exchanged include not only simple text data, but also video/audio.
In ordinary communication using electronic mail containing only text data, the contents of a received electronic mail are quoted to create a response mail. Thereby, pseudo-interactive communication is implemented. However, a method for sending a response mail quoting video/audio has not been developed to date. If a method is realized to enable an electronic mail containing video/audio to be quoted in a response mail as in the case of an electronic mail containing only text data, the usability thereof is considered to be significantly greater.
In the development of a method that enables video/audio received in an electronic mail to be quoted in a response mail, a major technical problem arises in how to reduce the amount of communication data. Generally, since video/audio is composed of a relatively large amount of data, a simple exchange of electronic mails using video/audio requires much communication time and cost.
Recently, television-based video/audio broadcasts can be recorded and stored as digital data in a PC or on a home-use server. Thereby, personal editorial processing is popularly performed for video and audio. Also in this case, since the amount of video/audio data is large, a reduction in the amount of data to be stored would be advantageous in miniaturization of a storage device and in the reduction of costs.
SUMMARY OF THE INVENTION
The present invention is made in view of the above-described problems. Accordingly, an object of the invention is to provide a video/audio-creating method and a video/audio-creating system that allow for a significant reduction in the amount of data, for example, transmitted in an electronic-mail communication and the amount of data to be stored in a storage device.
In order to achieve the above object, the present invention provides a method of reproducing a video/audio data set. The method comprises the steps of: (1) storing first data set of a video/audio data set into first memory; (2) copying the first data set from the first memory to second memory; (3) designating one or plural ranges in the first data set and a sequence of the ranges on the second memory; (4) sending the ranges and the sequence from the second memory to the first memory; and (5) reproducing the ranges in order of the sequence with reference to the first memory.
In the method, the second memory may store one or plural second data set(s) at the step (1). In this case, one or plural ranges in the first data set, and a sequence of the ranges and the second data set(s) are designated with reference to the second memory at the step (3). Third data set (metadata), which represents the ranges and the sequence and which includes the second data set(s), is generated with reference to the first memory. The third data set is sent from the second memory to the first memory at the step (4). And the ranges of the first data set and the second data set(s) are reproduced in order of the sequence with reference to the first memory.
In the method, at least one of the data sets transmitted between the first and second memories may be attached to an electronic mail.
In the method, the first and second memories may be embedded on different terminal devices from each other. Otherwise, the first and second memories may be embedded on different server devices from each other.
In the method, the first data set stored on the first memory at the step (1) may be previously received as broadcast video/audio. The step (5) may be made in order to broadcast the ranges of the first data set in order of the sequence.
Furthermore, in order to achieve the above object, the present invention provides a software product for reproducing a video/audio data set by computer. The software product comprises the processes of: (1) storing first data set of a video/audio data set into first memory; (2) copying the first data set from the first memory to second memory; (3) designating one or plural ranges in the first data set and a sequence of the ranges on the second memory; (4) sending the ranges and the sequence from the second memory to the first memory; and (5) reproducing the ranges in order of the sequence with reference to the first memory.
In the software product, the second memory may store one or plural second data set(s) at the process (1). In this case, one or plural ranges in the first data set, and a sequence of the ranges and the second data set(s) are designated with reference to the second memory at the process (3). Third data set, which represents the ranges and the sequence and which includes the second data set(s), is generated with reference to the first memory. The third data set is sent from the second memory to the first memory at the process (4). And the ranges of the first data set and the second data set(s) are reproduced in order of the sequence with reference to the first memory.
In the software product, at least one of the data sets transmitted between the first and second memories may be attached to an electronic mail.
In the software product, the first and second memories may be embedded on different terminal devices from each other. Otherwise, the first and second memories may be embedded on different server devices from each other.
In the software product, the first data set stored on the first memory at the process (1) may be previously received as broadcast video/audio. The process (5) may be made in order to broadcast the ranges of the first data set in order of the sequence.
And furthermore, in order to achieve the above object, the present invention provides a system for reproducing a video/audio data set by computer. The system comprises: first memory for storing first data set of a video/audio data set; second memory for being copied the first data set from the first memory; a unit for designating one or plural ranges in the first data set and a sequence of the ranges on the second memory; a unit for sending the ranges and the sequence from the second memory to the first memory; and
a unit for reproducing the ranges in order of the sequence with reference to the first memory.
In the system, the second memory may store one or plural second data set(s). In this case, the unit for designating designates one or plural ranges in the first data set, and a sequence of the ranges and the second data set(s) with reference to the second memory. The system further comprises a unit for generating third data sent which represents the ranges and the sequence and which includes the second data set(s) with reference to the first memory. The unit for sending sends the third data set from the second memory to the first memory. And the unit for reproducing reproduces the ranges of the first data set and the second data set(s) in order of the sequence with reference to the first memory.
In the system, at least one of the data sets transmitted between the first and second memories may be attached to an electronic mail.
In the system, the first and second memories may be embedded on different terminal devices from each other. Otherwise, the first and second memories may be embedded on different server devices from each other.
The system may further comprise a unit for receiving broadcast video/audio. In this case, the first memory stores received video/audio by the means for receiving as the first data set.
The system may further comprise a unit for broadcasting which broadcasts reproduction of the means for reproducing.
Accordingly, to reproduce the new video/audio including
