Abstract

According to one embodiment, there is provided a control block including a read control processor for reading designated content, a time information processor for processing time information. A controller returns, to a user terminal, a response signal, and information indicating a second absolute time point when an operation is executed in response to a request signal generated by the user terminal at a first absolute time point. The controller stores time difference information indicating a time difference between the first and the second absolute time points. When responding to a further request signal sent from the requester via the network, the controller sets, as tag time information, time information obtained by correcting, using the time difference information, a current relative time period for which the designated content is read.

Claims

1. An electronic recording/reading apparatus comprising:

a control module, the control module comprising a read control processor configured to read designated content, a time information processor configured to process time information, and a controller, wherein the controller comprises;

a first module configured to transmit to a user terminal a response signal and information indicating a second absolute time point when an operation is executed, the operation executed in response to a request signal generated by the user terminal at a first absolute time point, the request signal sent via a network;

a second module configured to store time difference information from the user terminal, the time difference information indicating a time difference between the first and the second absolute time points; and

a third module configured to determine tag time information based on the time difference information and a current relative time period for which the designated content is read.

2. The recording/reading apparatus of claim 1, further comprising a transmission module configured to transmit the tag time information to an external data managing server.

3. The recording/reading apparatus of claim 1, wherein the control module further includes a tag list managing unit configured to generate a tag list based on a plurality of determined tag time information, and transmit the tag list to an external data managing server.

8. The recording/reading apparatus of claim 1, wherein the tag time information is determined when responding to a further request signal sent from the user terminal via the network.

4. A control method implemented on an electronic recording/reading apparatus comprising a control module, the control module comprising a read control processor configured to read designated content, a time information processor configured to process time information and a controller, the control method comprising steps of:

transmitting, in response to a request signal generated by a user terminal at a first absolute time point and sent via a network, a response signal and information to the user terminal, the information indicating a second absolute time point when an operation is executed;

storing time difference information from the user terminal, the time difference information indicating a time difference between the first and the second absolute time points; and

determining tag time information by correcting, using the time difference information, a current relative time period for which the designated content is read, when responding to a further request signal sent from the use terminal via the network.

5. The control method of claim 4, further comprising transmitting the tag time information to an external data managing server.

6. The control method of claim 4, further comprising generating a tag list based on a plurality of determined tag time information, and transmitting the tag list to an external data managing server.

7. A multimedia editing system comprising:

a recording/reading apparatus comprising;

a read control processor configured to read designated content;

a time information processor configured to process time information;

means for transmitting, to a user terminal, a response signal and information, the information indicating a second absolute time point when an operation is executed in response to a request signal from the user terminal at a first absolute time point and sent via a network;

means for storing time difference information indicating a time difference between the first and the second absolute time point, and means for setting, as tag time information, time information obtained by correcting, using the time difference information, a current relative time period for which the designated content is read, when responding to a further request signal sent from the control terminal via the network; and

a user terminal configured to control the recording/reading apparatus, the user terminal comprising;

means for transmitting the request signal;

means for storing the information indicating the first absolute time point;

means for detecting the time difference between the first absolute time point and the second absolute time point to generate the time difference information; and

means for transmitting the generated time difference information to the recording/reading apparatus.
