Abstract

A method and apparatus for providing a plurality of sequential image data samples for display, is disclosed. A first one of the image data samples is accessed and then a second one of the image data samples is accessed. The first and second image data samples may then be provided for display, where one or more further data samples are provided in the event that the first and second image data samples are not contiguous. These further data samples indicate that image data samples are not available between the first and second image data samples.

Claims

1. A video data play back apparatus comprising:

an obtaining device configured to select a camera from a plurality of cameras, and to obtain live video data from the selected camera and recorded video data from a recording device, wherein the recorded video data is video data from the selected camera;

a display device configured to display a timeline indicating a range of time points, which includes time points of the recorded video data and a current time, and to display a play head which moves on the timeline to indicate a time point of video data being played back; and

a play back device configured to play back the recorded video data corresponding to the time point indicated by the play head,

wherein said play back device plays back the live video data received from the selected camera at the current time in response to the play head moving to indicate the current time, and

wherein said play back device plays back the recorded video data received from the recording device in response to the play head moving to indicate a past time.

2. The apparatus according to claim 1, further comprising

a selector by means of which a selection is made among two or more cameras,

wherein if said selector selects a second camera while said play back device plays back video data of a first camera, said play back device continues to play back the video data of the first camera.

3. The apparatus according to claim 1, wherein

said display device displays an indicator at a position on the timeline corresponding to an occurrence of an event, and

said play back device plays back video data corresponding to the event in response to a movement of the play head to the location of the indicator.

4. A method of video data play back, said method comprising the steps of:

selecting a camera from a plurality of cameras;

obtaining live video data from the selected camera and recorded video data from a recording device, wherein the recorded video data is video data from the selected camera;

displaying a timeline indicating a range of time points, which includes time points of the recorded video data and a current time;

displaying a play head which moves on the timeline to indicate a time point of video data being played back; and

playing back the recorded video data corresponding to the time point indicated by the play head,

wherein the live video data received from the selected camera at the current time is played back in response to the play head moving to indicate the current time, and

wherein the recorded video data received from the recording device is played back in response to the play head moving to indicate a past time.

5. The method according to claim 4, further comprising

selecting among two or more cameras,

wherein if a second camera is selected in said selecting step while video data of a first camera is played back in said playing back step, the video data of the first camera continues to be played back.

6. The method according to claim 4, wherein

said displaying step includes displaying an indicator at a position on the timeline corresponding to an occurrence of an event, and

said playing back step includes playing back video data corresponding to the event in response to a movement of the play head to the location of the indicator.

7. A non-transitory computer-readable storage medium storing, in executable form, a program for causing a computer device to execute a method to play back video data, said method comprising:

selecting a camera from a plurality of cameras;

obtaining live video data from the selected camera and recorded video data from a recording device, wherein the recorded video data is video data from the selected camera;

displaying a timeline indicating a range of time points, which includes time points of the recorded video data and a current time;

displaying a play head which moves on the timeline to indicate a time point of video data being played back; and

playing back the recorded video data corresponding to the time point indicated by the play head,

wherein the live video data received from the selected camera at the current time is played back in response to the play head moving to indicate the current time, and

wherein the recorded video data received from the recording device is played back in response to the play head moving to indicate a past time.

8. A non-transitory computer-readable medium according to claim 7, wherein the method further comprising

selecting among two or more cameras,

wherein if a second camera is selected in the selecting step while the video data of a first camera is played back, the video data of the first camera continues to be played back.

9. A non-transitory computer-readable medium according to claim 7, wherein

the displaying step includes displaying an indicator at a position on the timeline corresponding to an occurrence of an event, and

the playing back step includes playing back video data corresponding to the event in response to a movement of the play head to the location of the indicator.
