Abstract
A reproduction apparatus reproduces image data recorded in a plurality of recording modes with different tape feeding speeds from a tape-like recording medium. In this apparatus, in a search mode of searching for still image data by feeding the tape-like recording medium at a high speed, the recording mode of the still image data is discriminated, and the still image data is then reproduced.
Claims17
An apparatus for reproducing image data from a tape-like recording medium on which motion image data and still image data are recorded, the image data being recorded in a first recording mode of recording the image data by feeding the tape-like recording medium at a first speed and in a second recording mode of reproducing the data by feeding the tape-like recording medium at a second speed different from the first speed, comprising:
- feeding means for feeding the tape-like recording medium;
- reproduction means for reproducing digital data including the image data from the tape-like recording medium;
- and
- control means for discriminating a recording mode of the image data and controlling feeding operation of said feeding means and reproducing operation of said reproduction means, said control means, in a still image search mode of searching for the still image data by reproducing the digital data while feeding the tape-like recording medium at a high speed, determining whether the recording mode of the still image data is the first recording mode or the second recording mode while feeding a still image recording area of the tape-like recording medium at the high speed and, after determining the recording mode of the still image data, controlling said feeding means and said reproducing means so as to start reproducing the searched still image data by feeding the tape-like recording medium at a speed corresponding to the determined recording mode.
A reproduction apparatus for reproducing image data recorded in a plurality of recording modes with different tape feeding speeds from a tape-like recording medium, wherein in a search mode of searching for predetermined image data by reproducing the digital data while feeding the tape-like recording medium at a high speed, said apparatus determines a recording mode of the predetermined image data from among a plurality of recording modes while feeding a recording area of the predetermined image data of the tape-like recording medium at the high speed and, after determining the recording mode of the predetermined image data, starts reproducing the searched predetermined image data by feeding the tape-like recording medium at a speed corresponding to the determined recording mode.
A reproduction method of reproducing image data recorded in a plurality of recording modes with different tape feeding speeds from a tape-like recording medium, wherein in a search mode of searching for predetermined image data by reproducing the digital data while feeding the tape-like recording medium at a high speed, said method includes a step of determining a recording mode of the predetermined image data from among a plurality of recording modes while feeding a recording area of the predetermined image data of the tape-like recording medium at the high speed and, after determining the recording mode of the predetermined image data, starting reproducing the searched predetermined image data by feeding the tape-like recording medium at a speed corresponding to the determined recording mode.
A reproducing apparatus for reproducing image data from a tape-like recording medium, the image data being recorded in a first recording mode of recording the image data by feeding the tape-like recording medium at a first speed and in a second recording mode of recording the image data by feeding the tape-like recording medium at a second speed different from the first speed, comprising:
- feeding means for feeding the tape-like recording medium;
- reproduction means for reproducing digital data including the image data from the tape-like recording medium;
- and
- determining means for determining whether a recording mode of the image data reproduced by said reproduction means is the first recording mode or the second recording mode by interrupt processing of a microprocessor;
- and
- mode setting means for setting a mode of said apparatus between a plurality of modes including a normal reproduction mode in which said feeding means feeds the tape-like recording medium at a normal speed corresponding to the determined recording mode and the microprocessor performs the interrupt processing for a determining operation of the recording mode at a first interrupt interval, and a search reproduction mode in which said feeding means feeds the tape-like recording medium at a speed faster than the normal speed and the microprocessor performs the interrupt processing for the determining operation at a second interrupt interval shorter than the first interrupt interval.
