Claim:
A video recorder, comprising: a processor communicating with memory, the memory storing at least one of i) video data of an event and ii) audio data of the event, the video data comprising a series of picture frames; a loop buffer also storing at least one of the audio data and the video data of the event, the loop buffer also storing at least one of time-delayed audio data and time-delayed video data that precedes the event; and a set of rules stored in the memory, the set of rules specifying i) at least one of a region of interest and a region of disinterest within a single picture frame, ii) an occurrence that causes transfer of at least one of the time-delayed video data and the time-delayed audio data from the loop buffer to the memory, and iii) a first time and a second time, wherein if the occurrence happens within the at least one of the region of interest and the region of disinterest within a single picture frame at the first time, the set of rules further specifies that at least one of the time-delayed video data and the time-delayed audio data is transferred from the loop buffer to the memory, and if the occurrence happens within the at least one of the region of interest and the region of disinterest within a single picture frame at the second time, the set of rules further specifies that at least one of the time-delayed video data and the time-delayed audio data is not transferred from the loop buffer to the memory.
