Selective recall and preservation of continuously recorded data

A process for selectively recalling events, comprising:

• providing an acquisition buffer comprising at least one finite extent of a recording medium;
• recording in said acquisition buffer current events in place of earlier events, to insure that said acquisition buffer contains, at any given time, a record of the most recent events;
• providing selection means enabling a user to select a portion or portions of said record of the most recent events recorded in said acquisition buffer, in order to determine which portion or portions, if any, of said record of events will be recalled or played back;
• providing recall means for reproducing said record of events;
• and
• reproducing, using said recall means, any portion or portions of said record of events selected by said user using said selection means.

A device for selectively recording events, said device comprising:

• an acquisition buffer comprising at least one finite extent of a recording medium;
• a recorder in said acquisition buffer for recording current events in place of earlier events, to insure that said acquisition buffer contains, at any given time, a record of the most recent events;
• a selector for enabling a user to select a portion or portions of said record of the most recent events recorded in said acquisition buffer to determine which portion or portions, if any, of said record of events will be preserved;
• and
• a preserver to preserve any portion or portions of said record of events selected by said user, said preserving means includes:
• a reserver to reserve a portion of said record of events from being overwritten by other events;
• and
• a transferor for transferring said selected portions of the record of events to a predetermined location.

A device for selectively recalling events, said device comprising:

• an acquisition buffer comprising at least one finite extent of a recording medium;
• a recorder for recording current events in said acquisition buffer in place of earlier events, to insure that said acquisition buffer contains, at any given time, a record of the most recent events;
• a selector for enabling a user to select a portion or portions of said record of the most recent events recorded in said acquisition buffer to determine which portion or portions, if any, of said record of events will be preserved;
• and
• recall means for reproducing said record of events and any portion or portions of said record of events selected by said user using said selector.

A process for selectively recalling events, said process comprising the steps of:

• providing an acquisition buffer comprising at least one finite extent of a recording medium;
• recording in said acquisition buffer current events in place of earlier events, to insure that said acquisition buffer contains, at any given time, a record of the most recent events;
• and
• rapidly skipping or moving between parts of said record of events.
