A method, system and apparatus for image capture, analysis and transmission are provided. A link aggregation method involves identifying controller network ports to a source connected to the same subnetwork; producing packets associating corresponding controller network ports selected by the source CPU for substantially uniform selection; and transmitting the packets to their corresponding network ports. An image analysis method involves producing by a camera an indication whether a region of an image differs by a threshold extent from a corresponding region of a reference image; transmitting the indication and image data to a controller via a communications network; and storing at the controller the image data and the indication in association therewith. The controller may perform operations according to positive indications. A transmission method involves receiving user input in respect of a video stream and transmitting, in accordance with the user input, selected data packets of selected image frames thereof.

Adaptive video streaming

Generating signatures within a network that includes a plurality of computing devices of varying processing capabilities is disclosed. Chips may be transmitted, from a network video recorder and over the network, to an analytics appliance having a GPU processing power that is higher than a GPU processing power possessed by the network video recorder. The GPU processing power possessed by the analytics appliance may be employed to process the chips therein and generate respective signatures.

A system and method for playing back video feeds includes determining from the video feeds a subset of currently available video feeds, determining a playback layout based on the number of currently available video feeds and playing back the subset of currently available video feeds within the playback layout. The system and method further includes determining at least one change in availability in a given video feed of the plurality of video feeds, updating the subset of currently available video feeds based on the at least one change, updating the playback layout based on the updated subset of currently available video feeds and playing back the updated subset of currently available video feeds within the updated playback layout.

System and method for multiple video playback

A system for streaming multiple encodings of a source video stream is disclosed. A source video device system captures and/or receives source video comprising a plurality of source video frames. The source video device system encodes the source video frames into virtual frames, with each of the virtual frames being encoded using at least one different encoding parameter. The source video device system forms a container frame from the virtual frames and transmits the container frame over a network. In an example embodiment, the container frame comprises the virtual frames associated with a particular source frame and a container timestamp applicable to all of the virtual frames in the container frame.

Streaming multiple encodings encoded using different encoding parameters

Methods, systems, and techniques for tracing callstacks, the results of which can be used to identify a source of a memory leak. A memory heap is sampled at different times to determine counts of respective allocations of different allocations at the different times. From the counts of the respective allocations at the different times, rates at which the respective allocations have changed over the different times, and which of the rates is equal to or greater than a leak indication rate, are determined. Callstacks for respective allocations of the different allocation sizes for each of the rates that is equal to or greater than the leak indication rate are traced. The results of the tracing may be used during debugging to identify the source of the memory leak.

A computer implemented method for managing data received from a video source device is disclosed. At least a first storage tier and a second storage tier on a storage medium are identified for respectively storing different categories of data. As data streams are received from the video source, the data streams are associated with at least the first storage tier or the second storage tier and data from the received streams are stored in the associated storage tier. When the storage medium is full or meets some other specified maximum capacity threshold, data is deleted beginning with data that has an age that exceeds one or more specified maximum retention times, followed by data with the oldest age from one or both of the first and second storage tiers.

Storage management of data streamed from a video source device

There is provided an appearance search system comprising one or more cameras configured to capture video of a scene, the video having images of objects. The system comprises one or more processors and memory comprising computer program code stored on the memory and configured when executed by the one or more processors to cause the one or more processors to perform a method. The method comprises identifying one or more of the objects within the images of the objects. The method further comprises implementing a learning machine configured to generate signatures of the identified objects and generate a signature of an object of interest. The system further comprises a network configured to send the images of the objects from the camera to the one or more processors. The method further comprises comparing the signatures of the identified objects with the signature of the object of interest to generate similarity scores for the identified objects, and transmitting an instruction for presenting on a display one or more of the images of the objects based on the similarity scores.

Methods, systems, infrastructures and techniques for operating a multi-process application are described. The method includes starting a master process and the master process instantiating a first child process and a first inter-process communication (IPC) channel; and instantiating a second child process and a second IPC channel. The method further includes the master process instantiating a third IPC channel used for a direct peer-to-peer (P2P) communication; and providing first and second handles of the third IPC channel to the first and second child processes, using the first and second IPC channels, respectively. The first child process and the second child process can communicate directly using the received first and second handles of the third IPC channel.

Secured multi-process architecture

A physical security system may define sites associated with cameras. Sites may be added as a child site off of a parent site to form a site family. Once set up, ranked user and group privileges on the parent site may be pushed to the child sites, and controlled by the parent site. The child sites may still define local users and groups so that the child site may operate if there is a loss of connectivity to the parent site.

Distributed security system over multiple sites

Methods, systems, and techniques for handling of event notifications in non-standard formats. An event notification sent from an event notification sending device of a video surveillance system is received at an event notification handling device of the system. The event notification is in a format not natively supported by at least one device of the system. The event notification is translated into a format supported by the at least one device, with the supported format being defined in a list of non-standard formats. A rule associated with the event notification is applied to perform an action. Prior to receiving the event notification, an initialization method may be performed in which the event notification handling device subscribes to receive the event notification.
