A multimedia event recording apparatus, and more particularly, a multimedia event recording method by which multimedia data and multimedia event contents are related and then stored, and an apparatus suitable for the method are provided. The multimedia recording method includes: detecting an occurrence of a control event in relation to multimedia data; closing a file in which an audio and/or video (A/V) stream is being recorded if the control event occurs, before the control event occurs is recorded; recording a position of data at which the control event corresponding to the closed file occurs and file information of the closed file in a mark table; and opening a new file and storing an A/V stream after the control event occurs.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A multimedia conference recording method comprising: receiving, as one of participants of a multimedia conference, multimedia conference data materials and an audio and visual (A/V) stream, the A/V stream comprising at least one of an audio stream of the multimedia conference and a video stream of the multimedia conference; detecting an occurrence of a control event in relation to the multimedia conference data materials; closing a first file in which a portion of the A/V stream occurring before the occurrence of the control event is recorded; and recording in a second file a portion of the A/V stream occurring after the occurrence of the control event; wherein the control event is shared with the other participants of the multimedia conference, the control event is a turning of a page of the conference data materials, and the control event is shared comprises transmitting, in response to occurring the control event indicating turning of the page, the control event to the other participants, and displaying a next page of the conference data materials on screens of the other participants.
2. The method of claim 1 , further comprising recording in the mark table, upon the occurrence of the control event, position information of the multimedia conference data materials and file information of the first file.
3. The method of claim 2 , wherein upon the occurrence of the control event, the closing of the first file, and the recording in the second file, and the recording in the mark table are performed repeatedly.
4. The method of claim 2 , wherein the mark table contains at least two records with respect to the multimedia conference, each one of the records containing respective position information of the multimedia conference data materials and file information of files containing A/V streams of the multimedia conference.
5. The method of claim 2 , wherein the mark table contains a mapping table of position information of the multimedia conference data materials and file information of files containing A/V streams of the multimedia conference.
6. The method of claim 2 , wherein the position information of the multimedia conference data materials comprises a page number of the multimedia conference data materials.
7. A multimedia conference terminal comprising: an interface unit which performs interfacing among multimedia conference terminals; a conference data materials control unit which controls transmission of conference data materials, as one of participants of a multimedia conference, through the interface unit; a VoIP control unit which performs control for conducting a multimedia conference, transmission of an A/V stream comprising at least one of an audio stream of the multimedia conference and a video stream of the multimedia conference, transmission of multimedia conference data materials, control of the multimedia conference data materials, and control of a multimedia conference call; and a recording control unit which records the A/V stream received by the interface unit in a first file, wherein the recording control unit, upon an occurrence of a control event in relation to the multimedia conference data materials, closes the first file, and records in the second file a portion of the A/V stream occurring after the control event, and wherein the control event is shared with the other participants of the multimedia conference, the control event is a turning of a page of the conference data materials, and the control event is shared comprises transmitting, in response to occurring the control event indicating turning of the page, the control event to the other participants, and displaying a next page of the conference data materials on screens of the other participants.
8. The multimedia terminal of claim 7 , wherein, upon the occurrence of the control event, the recording control unit records in the mark table, position information of the multimedia conference data materials and file information of the first file.
9. The multimedia conference terminal of claim 7 , wherein the position information of the multimedia conference data materials comprises a page number of the multimedia conference data materials.
10. The multimedia conference terminal of claim 7 , wherein the A/V stream is divided into a plurality of A/V stream files in synchronization with control events.
11. The multimedia conference terminal of claim 8 , wherein the mark table contains a mapping table of respective position information of the multimedia conference data materials and file information of files containing A/V streams of the multimedia conference.
