Video analytics with pre-processing at the source end
First Claim
1. A method comprising:
- receiving at a source end video data including first video data relating to an event of interest and second video data other than relating to the event of interest, the video data captured using a video camera disposed at the source end;
using video analytics to detect the first video data and the second video data within the video data;
pre-processing the video data at the source end to reduce the bandwidth requirement for transmitting the pre-processed video data to below a bandwidth limit of a Wide Area Network (WAN) over which the pre-processed video data is to be transmitted, wherein the pre-processing comprises selectively formatting the second video data differently than the first video data;
transmitting the pre-processed video data to a central server via the WAN;
performing other video analytics processing of the pre-processed video data at other than the source end; and
,based on a result of the other video analytics processing, generating a signal for performing a predetermined action in response to an occurrence of the event of interest at the source end.

Abstract
A method for performing video analytics includes receiving at a source end video data including first video data relating to an event of interest. Using video analytics, other than a data compression process, pre-processing of the video data is performed at the source end to reduce the bandwidth requirement for transmitting the video data to below a bandwidth limit of a Wide Area Network (WAN) over which the video data is to be transmitted. The pre-processed video data is transmitted to a central server via the WAN, where other video analytics processing of the pre-processed video data is performed. Based on a result of the other video analytics processing, a signal is generated for performing a predetermined action, in response to an occurrence of the event of interest at the source end.

12. A method comprising:
-
receiving video data at a source end, the video data including video data relating to an event of interest captured using a video camera disposed at the source end; using video analytics other than a data compression process, pre-processing the video data at the source end such that a first portion of the video data in which the event of interest is detected is formatted differently than a second portion of the video data in which the event of interest is other than detected; transmitting the pre-processed video data from the source end to a central server via a Wide Area Network (WAN); performing other video analytics processing of the pre-processed video data at other than the source end; and
,based on a result of the other video analytics, generating a signal for performing a predetermined action in response to an occurrence of the event of interest at the source end, wherein pre-processing reduces the bandwidth requirement for transmitting the second portion of the video data, such that a time-averaged bandwidth requirement of the pre-processed video data is lower than a bandwidth limit of the WAN over which the pre-processed video data is to be transmitted. - View Dependent Claims (13, 14, 15, 16, 17, 18)
