Abstract
A video apparatus includes signal control unit that outputs an image signal in a plurality of formats. An interface unit connects the video apparatus to a computer, and an interface control unit controls transmission of the image signal to the computer. When the video apparatus has been connected to the computer through the interface unit, when the format of the image signal is switched, the interface control unit controls the interface unit so that the connection to the computer is disconnected without changing a physical connecting state. After the elapse of a predetermined period, the video apparatus is connected to the computer again without changing the physical connecting state.
Claims23
A video apparatus comprising:
- signal control means for outputting an image signal in a plurality of formats;
- interface means for connecting said video apparatus to a computer;
- and
- interface control means for controlling transmission so as to transmit said image signal to said computer by using said interface means,
- wherein when the video apparatus has been connected to said computer through said interface means, said interface control means controls said interface means to automatically and logically disconnect the connection to said computer without changing a physical connecting state and without user intervention, in response to a detecting result indicating that the format of said image signal is switched and, after the elapse of a predetermined period, the video apparatus is connected to said computer again without changing the physical connecting state.
A video output control method comprising:
- a transmitting step of controlling so that an image signal which can be outputted in a plurality of formats is transmitted to a computer through interface means for connecting a video apparatus to said computer;
- and
- a disconnecting/re-connecting step of, when the video apparatus has been connected to said computer in said transmitting step, controlling said interface means to automatically and logically disconnect the connection to said computer without changing a physical connecting state and without user intervention, in response to a detecting result indicating that the format of said image signal is switched, and further after the elapse of a predetermined period, to connect the video apparatus to said computer again without changing the physical connecting state.
A reproduction control method in a recording/reproducing apparatus having a recording/reproducing function of recording/reproducing a signal through a recording medium so that a plurality of signal formats mixedly exist and a communicating function of establishing connection to an external apparatus and outputting a reproduction signal, comprising:
- a transmitting step of controlling so that a video signal which can be outputted in a plurality of formats is transmitted to said external apparatus through interface means for connecting said recording/reproducing apparatus to said external apparatus;
- a disconnecting/re-connecting step of, when the recording/reproducing apparatus has been connected to said external apparatus in said transmitting step, controlling said interface means to automatically and logically disconnect the connection to said external apparatus without changing a physical connecting state and without user intervention, in response to a detecting result indicating that the format of said image signal is switched, and further after the elapse of a predetermined period, to connect the recording/reproducing apparatus to said external apparatus again without changing the physical connecting state;
- and
- a reproduction control step of controlling the reproducing operation of said recording/reproducing apparatus,
- wherein in said reproduction control step, when a reproducing mode has been set to a specific reproducing mode, the reproduction of a recording portion of the format which does not correspond to said reproducing mode is skipped.
A reproduction control method in a recording/reproducing apparatus having a recording/reproducing function of recording/reproducing a signal through a recording medium so that a plurality of signal formats mixedly exist and a communicating function of establishing connection to an external apparatus and outputting a reproduction signal, comprising:
- a transmitting step of controlling so that a video signal which can be outputted in a plurality of formats is transmitted to said-external apparatus through interface means for connecting said recording/reproducing apparatus to said external apparatus;
- a disconnecting/re-connecting step of, when the recording/reproducing apparatus has been connected to said external apparatus in said transmitting step, controlling said interface means to automatically and logically disconnect the connection to said external apparatus without changing a physical connecting state and without user intervention, in response to a detecting result indicating that the format of said image signal is switched, and further after the elapse of a predetermined period, to connect the recording/reproducing apparatus to said external apparatus again without changing the physical connecting state;
- and
- a video output control step of controlling the video output operation of said recording/reproducing apparatus,
- wherein in said the video output control step, when a reproducing mode has been set to a specific reproducing mode, a dummy signal of a format corresponding to said reproducing mode is outputted at the time of the reproduction of a recording portion of the format which does not correspond to said reproducing mode.
A video apparatus comprising:
- a signal control unit configured to output an image signal in a plurality of formats;
- an interface unit configured to connect said video apparatus to a computer;
- and
- an interface control unit configured to control so as to transmit said image signal to said computer by using said interface unit,
- wherein in the case where the video apparatus has been connected to said computer through said interface unit, said interface control unit controls said interface unit to automatically and logically disconnect the connection to said computer without changing a physical connecting state and without user intervention, in response to a detecting result indicating that the format of said image signal is switched and, further after the elapse of a predetermined period, the video apparatus is connected to said computer again without changing the physical connecting state.
