1. 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.

Abstract
A video recorder is disclosed for recording audio and video data of an event. The video recorder includes a processor communicating with memory. The memory stores audio and/or video data of an event. The video data includes a series of picture frames. A set of rules is also stored in the memory. The set of rules specifies either i) multiple regions of interest and/or ii) multiple regions of disinterest within a single picture frame. The set of rules dynamically varies a bitrate of the audio/video data associated with each region of interest and with each region of disinterest. The audio/video data is stored in the memory according to the bitrate specified by the set of rules.

17. A video recorder, comprising:
-
a processor communicating with memory, the memory storing at least one of audio data and video data of an 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) a first 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 ii) a second occurrence, wherein if the first occurrence happens, then the set of rules further specifies determining whether the second occurrence is also happening, and if the second occurrence is also happening, then 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. - View Dependent Claims (18, 19, 20)
