A device for recording and playing back a selected episode from an input analog audio-visual signal. A "deferred recording" feature allows the user to briefly delay his/her decision to record a live signal episode until after the signal episode has at least partially transpired. Thus, the user can first evaluate the episode prior to deciding whether to record it. The recorded signal episode contains both preamble and postamble segments, i.e. the signal segments preceding and following activation of a record switch. The analog playback signal is directed to an A/V output device so it can be heard/viewed by the user. Some embodiments provide for recording multiple signal episodes, multi-signal channel episodes, variable length episodes, simultaneous record and playback, episode deletion, variation of sampling rate, skip forward, reverse, and squelch. |

DETAILED DESCRIPTION What is claimed is: 1.
An audio/visual signal recorder for recording an episode of a first audio/visual sign, wherein said episode comprises a preamble time segment and a postamble time segment, said recorder comprising: means for recording the preamble time segment of said audio/visual signal episode; means for recording the postamble time segment of said audio/visual sign episode, wherein said postamble recording means is actuated by a user input, wherein the postamble time segment comprises a portion of said audio/visual signal episode occurring after the user input actuation; and audio/visual signal episode playback means comprising means for playing back said recorded preamble time segment followed by said recorded postamble time segment.
2.
The recorder of claim 1, wherein said means for recording a preamble time segment and said means for recording a postamble time segment comprise a digital data storage means for storing the recorded segments.
3.
The recorder of claim 1, wherein the means for recording a preamble time segment, the means for recording a postamble time segment, and the means for playing back comprise a microcontroller.
4.
The recorder of claim 1, wherein said means for recording a postamble time segment comprises means for selecting the length of the postamble time segment.
5.
The recorder of claim 1, further comprising means for determining a recording sampling rate according to an input control signal.
6.
The recorder of claim 1, further comprising means for determining a recording sampling rate based on said first audio/visual signal.
7.
The recorder of claim 1, wherein said playback means further comprises means for bypassing a short section of the signal episode according to a first input control signal; and means for returning to a previously played point in the signal episode in response to a second input control signal.
8.
The recorder of claim 1, further comprising means for squelching recording, whereby quiescent signal intervals of said first audio/visual signal are not recorded
