Claims
- 1. A system for providing random access to a data set, preferably an audio and/or video data set, comprising:
- means, including a user interface, for capturing of said indicia hand generated by a user during a serial rendition of said data set so that each indicium is time correlated with a respective part of said data set, such indicia being available for subsequent selection by a user; and
- means for indexing into said data set to identify the part thereof that is time correlated with any indicium a user selects from said indicia; said system being characterized by including.
- means for automatically time-stamping each indicium upon its generation by the user, and means for automatically time-stamping the part of said data set with which said indicium is time correlated substantially concurrently with the time-stamping of said indicium, with all such time-stamping being referenced to a common time base;
- means for automatically storing, retrieving and displaying said user-generated indicia; and
- means for determining the time-stamp of each user-selected indicium for use by said indexing means;
- said user interface being adapted for electronically both capturing and displaying said user generated indicia.
- 2. The system according to claim 1, wherein said indexing means includes means for identifying the part of the data set having the same time-stamp as that determined by the determining means.
- 3. The system according to claim 1, wherein the determining means includes a look-up table of indicia and corresponding time stamp information.
- 4. The system according to claim 2, wherein the determining means includes a look-up table of indicia and corresponding time stamp information.
- 5. A system according to claim 3, wherein the identifying means includes a look-up table of time-stamp information and corresponding data reference information.
- 6. A system according to claim 4, wherein the identifying means includes a look-up table of time-stamp information and corresponding data reference information.
- 7. A system according to claim 6, wherein said data set and said look-up tables are stored in separate storage means.
- 8. A system according to claims 1-7, further including a reproduction device for reproducing the identified part of said data set.
- 9. A system according to claim 8, including means for commanding the reproduction device to reproduce said identified part, commencing with the video frame corresponding to the time stamp of the selected indicia.
- 10. A system according to claim 8, wherein said data reference information comprises field numbers and/or timecodes.
