Abstract
An apparatus for reproducing video data recorded on a tape-shaped recording medium in one of a first recording mode in which the video data is recorded while the tape-shaped recording medium is transported at a first speed and a second recording mode in which the video data is recorded while the tape-shaped recording medium is transported at a second speed different from the first speed, is arranged to reproduce the video data, in the case of a slow reproduction mode, while transporting the tape-shaped recording medium at a predetermined speed irrespective of the recording mode of the video data.
Claims24
An apparatus for reproducing video data recorded on a tape-shaped recording medium in one of a first recording mode in which the video data is recorded while the tape-shaped recording medium is transported at a first speed one after another and a second recording mode in which the video data is recorded while the tape-shaped recording medium is transported at a second speed different from the first speed one after another, said apparatus comprising:
- transport means for transporting the tape-shaped recording medium;
- reproducing means for reproducing the video data from the tape-shaped recording medium;
- and
- mode setting means for selectively setting one of a plurality of modes including a first slow reproduction mode in which video data recorded in the first recording mode is reproduced by said reproducing means while the tape-shaped recording medium is transported by said transport means at a third speed different from each of the first and second speeds and a second slow reproduction mode in which video data recorded in the second recording mode is reproduced by said reproducing means while the tape-shaped recording medium is transported by said transport means at the third speed.
An apparatus for reproducing video data recorded on a tape-shaped recording medium in one of a plurality of recording modes in which the video data is recorded while the tape-shaped recording medium is transported at respective different speeds, said apparatus comprising:
- transport means for transporting the tape-shaped recording medium;
- reproducing means for reproducing the video data from the tape-shaped recording medium;
- and
- control means for controlling said transport means and said reproducing means so as to reproduce the video data by making intermittent driving of the tape-shaped recording medium in a slow reproduction mode,
- said intermittent driving including a first period during which the tape-shaped recording medium is transported at a predetermined speed and a second period during which the tape-shaped recording medium is stopped from being transported,
- said control means varying a length of the first period according to a recording mode in which the video data to be reproduced has been recorded.
An apparatus for reproducing video data recorded on a tape-shaped recording medium in one of a first recording mode in which the video data is recorded by using a first rotary head having a first azimuth and a second rotary head having a second azimuth different from the first azimuth to form a number of tracks on the tape-shaped recording medium and a second recording mode in which the video data is recorded by using said first rotary head and a third rotary head disposed close to said first rotary head and having the second azimuth to form a number of tracks on the tape-shaped recording medium, said apparatus comprising:
- reproducing means for reproducing the video data from the tape-shaped recording medium by using said first, second and third rotary heads;
- and
- mode setting means for selectively setting one of a plurality of modes including a first slow reproduction mode in which video data recorded in the first recording mode is reproduced by using said first and second rotary heads while the tape-shaped recording medium is transported at a speed slower than a speed used in recording and a second slow reproduction mode in which video data recorded in the second recording mode is reproduced by using said first and second rotary heads while the tape-shaped recording medium is transported at a speed slower than a speed used in recording.
An apparatus for reproducing video data recorded on a tape-shaped recording medium in one of a plurality of recording modes in which the video data is recorded at respective different speeds, said apparatus comprising:
- transport means for transporting the tape-shaped recording medium;
- reproducing means for reproducing the video data from the tape-shaped recording medium;
- and
- control means for controlling said transport means and said reproducing means so as to reproduce the video data by making intermittent driving of the tape-shaped recording medium in a slow reproduction mode,
- said intermittent driving including a first period during which the tape-shaped recording medium is transported at a predetermined speed and a second period during which the tape-shaped recording medium is stopped from being transported,
- said control means varying a length of the second period according to a recording mode in which the video data to be reproduced has been recorded.
An apparatus for reproducing video data recorded on a tape-shaped recording medium in one of a first recording mode in which the video data is recorded by using a first rotary head having a first azimuth and a second rotary head having a second azimuth different from the first azimuth to form a number of tracks on the tape-shaped recording medium and a second recording mode in which the video data is recorded by using said first rotary head and a third rotary head arranged in position with a phase difference of predetermined degrees with a respect to the first rotary head and having the second azimuth to form a number of tracks on the tape-shaped recording medium, said apparatus comprising:
- reproducing means for reproducing the video data from the tape-shaped recording medium by using said first, second and third rotary heads;
- and
- mode setting means for selectively setting one of a plurality of modes including a first slow reproduction mode in which video data recorded in the first recording mode is reproduced by using said first and second rotary heads while the tape-shaped recording medium is transported at a speed slower than a speed used in recording and a second slow reproduction mode in which video data recorded in the second recording mode is reproduced by using said first and second rotary heads while the tape-shaped recording medium is transported at a speed slower than a speed used in recording.
An apparatus for reproducing video data recorded on a tape-shaped recording medium in one of a first recording mode in which the video data is recorded while the tape-shaped recording medium is transported at a first speed and a second recording mode in which the video data is recorded while the tape-shaped recording medium is transported at a second speed different from the first speed, said apparatus comprising:
- transport means for transporting the tape-shaped recording medium;
- reproducing means for reproducing the video data from the tape-shaped recording medium;
- and
- mode setting means for selectively setting one of a plurality of modes including a first slow reproduction mode in which video data recorded in the first recording mode is reproduced by said reproducing means while the tape-shaped recording medium is transported by said transport means at a third speed different from each of the first and second speeds and a second slow reproduction mode in which video data recorded in the second recording mode is reproduced by said reproducing means while the tape-shaped recording medium is transported by said transport means at the third speed,
- wherein said transport means makes intermittent driving of the tape-shaped recording medium in the first slow reproduction mode and in the second slow reproduction mode, and the intermittent driving includes a first period during which the tape-shaped recording medium is transported at the third speed and a second period during which the tape-shaped recording medium is stopped from being transported, and
- wherein an amount of information of the video signal for one frame recorded in the second recording mode is 1/N (N being an integer not less than 2) of that recorded in the first recording mode, and a length of the first period in the second slow reproduction mode is 1/N of that of the first period in the first slow reproduction mode.
