Abstract

One of the constituent devices of a video recording/delivering system can be replaced with a generic IT device, without impairing functions which are implemented by the entire video recording/delivering system by using a dedicated protocol specialized for the video recording/delivering system among the devices which constitute the video recording/delivering system, thereby reducing the cost of the video recording/delivering system. Each network camera receives a video data delivery request, which is transmitted from a network camera control terminal by using a dedicated protocol specialized for a video recording/delivering system, by using the dedicated protocol specialized for the video recording/delivering system and delivers, in response to the video data delivery request, currently captured live video data, or video data which are obtained from a storage device by using a general-purpose protocol, to the network camera control terminal by using the dedicated protocol specialized for the video recording/delivering system.

Claims

1. A network camera that is connected with a data recording device and a network camera control terminal via a network, including:

a storage unit; and

an operation processing unit,

wherein the operation processing unit receives a delivery request for video data transmitted from the network camera control terminal using a first protocol via the network using the first protocol, and

the operation processing unit delivers live video data that is being currently projected and temporarily recorded in the storage unit or video data that is acquired from the data recording device using a second protocol and temporarily recorded in the storage unit to the network camera control terminal via the network using the first protocol in response to the delivery request for the video data.

2. The network camera according to claim 1,

wherein the second protocol is a general-purpose protocol, and the data recording device is a storage device.

3. A network camera control terminal that is connected with a data recording device and a plurality of network cameras via a network, including:

an input unit;

a storage unit;

an operation processing unit; and

a display unit,

wherein the operation processing unit allocates video data to be displayed on each of a plurality of screen regions of the display unit based on operation information received through the input unit,

the operation processing unit decides a network camera that delivers the video data to the network camera control terminal for each allocated video data based on specification information of each of the network cameras stored in the storage unit and a setting state or an operation state of each of the network cameras,

the operation processing unit transmits a delivery request for the video data to each of the decided network cameras via the network, and

the operation processing unit receives the video data requested by the delivery request from each of the decided network cameras via the network, and causes the received video data to be displayed on the screen region.

4. The network camera control terminal according to claim 3,

wherein the video data is video data recorded in the data recording device or live video data being currently projected by the network camera.

5. The network camera control terminal according to claim 4,

wherein the data recording device is a storage device that supports a general-purpose protocol.

6. The network camera control terminal according to claim 5,

wherein the screen regions include a large screen region on which video data delivered at a high resolution and a high frame rate is displayed and a small screen region on which video data delivered at a low resolution and a low frame rate is displayed.

7. A video recording/delivering system, including:

a plurality of network cameras that are connected to a network;

a data recording device; and

a network camera control terminal,

wherein each of the network cameras receives a delivery request for video data transmitted from the network camera control terminal using a first protocol via the network using the first protocol,

each of the network cameras delivers live video data that is being currently projected and temporarily recorded in a storage unit or video data that is acquired from the data recording device using a second protocol and temporarily recorded in the storage unit to the network camera control terminal via the network using the first protocol in response to the delivery request for the video data,

the network camera control terminal transmits a delivery request for the video data to each of the network cameras via the network using the first protocol, and

the network camera control terminal receives the video data requested by the delivery request using the first protocol from each of the network cameras via the network using the first protocol, and causes the received video data to be displayed on a display unit.

8. The video recording/delivering system according to claim 7,

wherein the second protocol is a general-purpose protocol, and the data recording device is a storage device.

9. The video recording/delivering system according to claim 8,

wherein the network camera control terminal allocates video data to be displayed on each of a plurality of screen regions of the display unit based on operation information received through an input unit,

the network camera control terminal decides a network camera that delivers the video data to the network camera control terminal for each allocated video data based on predetermined specification information of each of the network cameras and a setting state or an operation state of each of the network cameras,

the network camera control terminal transmits a delivery request for the video data to each of the decided network cameras via the network using the first protocol, and

the network camera control terminal receives the video data requested by the delivery request from each of the decided network cameras via the network using the first protocol, and causes the received video data to be displayed on the screen region.

10. The video recording/delivering system according to claim 9,

wherein the screen regions include a large screen region on which video data delivered at a high resolution and a high frame rate is displayed and a small screen region on which video data delivered at a low resolution and a low frame rate is displayed.
