Flexible marking of recording data by a recording unit
First Claim
1. A recording unit for recording an event, comprising:
- a data acquisition device for obtaining recording data representing the content of the event;
a data storage device for storing data, wherein the stored data includes the recording data;
a control interface device for enabling a user to control operation of the recording unit, the control interface device further comprising marking means for enabling the user to specify multiple types of non-contemporaneous marks;
a system controller that causes, in response to the specification of a non-contemporaneous mark and a time value relative to the marking time of the non-contemporaneous mark specified by the user, the data storage device to store marking data associating the non-contemporaneous mark with the recording data obtained at a marked time relative to the marking time by the specified time value;
wherein the marking data defines a confidence level that represents the certainty of the user that the marked time associated with the marked recording data is a time associated with the recording data that the user desires to mark and the confidence level is associated with the specified time value relative to the marking time.

Abstract
The invention enables a recorder to mark a recording as an event is being recorded. The invention can enable the specification of a mark so that the mark is associated with recording data obtained at a time other than the time at which the mark is specified (“non-contemporaneous marking”), i.e., prior to the time of the mark (“retrospective marking”) or after the time of the mark (“predictive marking”). The invention can also enable the use of multiple types of marks, each type of mark having a particular meaning. Additionally, the invention can enable marking capability to be implemented so that specification of a mark causes predetermined operation of the recording unit in accordance with the type of the mark (“augmented marking”).

34. For use in a recording unit being used by a user to record an event, a method for non-contemporaneously marking recording data obtained by the recording unit, comprising the steps of:
-
identifying a specification of a non-contemporaneous mark of a specified type and a specified time value relative to the marking time of the non-contemporaneous mark; and in response to an identification of the specification of a non-contemporaneous mark, storing marking data associating the non-contemporaneous mark with recording data obtained at a marked time relative to the marking time by the specified time value; wherein the marking data defines a confidence level that represents the certainty of the user that the marked time associated with the marked recording data is a time associated with the recording data that the user desires to mark, and the confidence level is associated with the specified time value relative to the marking time. - View Dependent Claims (35, 36, 37, 38, 39, 40, 41)
