Abstract

It was impossible to easily carry recorded images and sound by using a low-capacity memory medium and to receive them in the open air.

The present invention is a recording/reproducing apparatus comprising a compression stream generation means of generating (1) a first bit stream and (2) a second bit stream having a bit rate less than the bit rate of the first bit stream by using a video signal input externally, a recording/modulation means of recording the generated first bit stream and the generated second bit stream on a predetermined medium, a first digital interface of outputting the recorded first bit stream, and a second digital interface, having an interface connectable to a predetermined compact memory apparatus, of outputting the recorded second bit stream.

Claims

1. A recording apparatus comprising:

generation means of generating (1) a first bit stream and (2) a second bit stream having a bit rate less than the bit rate of said first bit stream by using a video signal input externally,

recording means of recording said generated first bit stream and said generated second bit stream on a predetermined medium,

first bit stream output means of outputting said recorded first bit stream, and

second bit stream output means, having an interface connectable to a predetermined compact memory apparatus, of outputting said recorded second bit stream.

2. A recording apparatus as set forth in claim 1, wherein the bit rate of said second bit stream is determined in consideration of the recording capacity of said compact memory means.

3. A recording apparatus as set forth in claim 1, comprising display means of carrying out display on the basis of the contents of a control table of controlling at least said recorded second bit streams, and selection means of selecting a predetermined second bit stream from said recorded second bit streams, wherein

said second bit stream output means outputs said selected second bit stream.

4. A recording apparatus as set forth in claim 1, comprising control means of controlling the received range, received by the user, of said recorded first bit stream and said recorded second bit stream.

5. A recording apparatus as set forth in claim 4, wherein

said recorded first bit stream is output from said first bit stream output means and used for reception by said user,

said control means controls the received range, received by said user, of said first bit stream, and

said second bit stream output means outputs the unreceived range, other than the received range of said controlled first bit stream, of the second bit stream generated by using the video signal used to generate the first bit stream.

6. A recording apparatus as set forth in claim 4, wherein

said recorded second bit stream is output from said second bit stream output means and used for reception by said user,

said control means controls the received range, received by said user, of said second bit stream, and

said first bit stream output means outputs the unreceived range, other than the received range of said controlled second bit stream, of the first bit stream generated by using the video signal used to generate the second bit stream.

7. A recording apparatus as set forth in claim 1, comprising image display means of displaying (1) an image using a first bit stream or (2) plural images using respective plural second bit streams, having been recorded on said medium, and selection means of selecting a predetermined second bit stream from said recorded second bit streams by utilizing the result of the display of plural images by using said respective plural second bit stream, wherein

said image display means displays an image using said first bit stream by using said first bit stream generated by utilizing the video signal utilized for the generation of the selected second bit stream.

8. A recording apparatus as set forth in claim 1, comprising image display means of displaying (1) an image using a first bit stream and (2) plural images using respective plural second bit streams, having been recorded on said medium, simultaneously.

9. A recording apparatus as set forth in claim 1, wherein said second bit stream output means has an interface of connecting to a predetermined communication network using wire and/or wireless.

10. A recording method comprising:

a step of generating (1) a first bit stream and (2) a second bit stream having a bit rate less than the bit rate of said first bit stream by using a video signal input externally,

a step of recording said generated first bit stream and said generated second bit stream on a predetermined medium,

a step of outputting said recorded first bit stream, and

a step of outputting said recorded second bit stream by utilizing an interface connectable to a predetermined compact memory apparatus.

11. A program causing a computer to execute all or part of:

a step of generating (1) a first bit stream and (2) a second bit stream having a bit rate less than the bit rate of said first bit stream by using a video signal input externally, a step of recording said generated first bit stream and said generated second bit stream on a predetermined medium, a step of outputting said recorded first bit stream, and a step of outputting said recorded second bit stream by utilizing an interface connectable to a predetermined compact memory apparatus;

in the recording method set forth in claim 10.

12. A medium having said program set forth in claim 11, being processable by a computer.
