Abstract: A system may route media stream samples in time-stamped packets to a media interface. The system may determine a hash value from a stream identifier that identifies a source media stream corresponding to the media stream samples. The hash value may be determined based on a combination of a first portion of the stream identifier and a second portion of the stream identifier. The system may determine whether the stream identifier identifies a subscribed media stream by looking up the hash value in a hash table. The system may route the media stream samples to a media interface if source media stream is a subscribed media stream.

Abstract: Various embodiments relate to creating and utilizing a vehicle surveillance network to monitor objects and/or events. Messages may be broadcasted from at least one communication system of a surveillance network which is communicating with one or more vehicles of the surveillance network and received in a vehicle. Instructions may be transmitted to at least one vehicle camera to capture one or more images of objects or events outside of the vehicle in response to receiving the at least one broadcasted message. At least one vehicle camera in each of the vehicles of the surveillance network may capture the images of the object and/or events. Further instructions may include transmitting the captured images from the one or more vehicles to one or more event responders.

Abstract: A network communication system includes a central control system that may transmit a request packet over a network to an apparatus that is configured to operate in an alarm system. The alarm system may be configured in accordance with a standard or protocol. The request packet may include instructions that instruct the apparatus to perform one or more tests that determine whether the apparatus is compliant with the standard or protocol. The apparatus may be configured to receive the packet from over the network and perform the tests in accordance with the instructions. The apparatus may report test results of the tests to the central control system by sending a reply packet that includes the test results over the network to the central control system.

Abstract: A low-level processing system is configured to send information relating to image characteristics to a high-level analytic processing system. The low-level processing system is configured to determine image characteristic values corresponding to one or more image characteristics associated with the image data. The low-level processing system is further configured to determine relationships between the image characteristic values and predetermined targets associated with the image characteristics. The predetermined targets may indicate values of the image characteristics that are desired to analytically process the image data. The relationships may indicate whether the image characteristic values match the predetermined targets. The relationships may also indicate locations outside of the predetermined targets where image characteristics do not match the predetermined targets.

Abstract: A network media adapter includes peripheral interfaces for connection to connectors of audio/video (“A/V”) sources and sinks to respectively receive media data from the A/V sources and to transmit media data to the A/V sinks. Components are configured to syntonize or synchronize local media clocks of the A/V sources and sinks to ensure media data integrity affiliated with a protocol of a media network over which the media data is transported. A quality of service (QoS)-compliant media interface is integrated in the network media adapter through which to send and receive processed A/V media data to and from the media network according to the protocol. Other components may be configured to process, encapsulate, and transport over the media network the media data received from the A/V sources. Still other components may be configured to receive media data from the media network and decapsulate, process, and transmit the media data through one or more peripheral interfaces connected to the A/V sinks.

Abstract: A system may be provided for synchronizing a first media stream with a second media stream. A first receiver in the system may receive the first media stream over a network. A second receiver in the system may receive the second media stream over the network. The second receiver may determine an identity of a content delay matching stream that indicates the amount of processing delay introduced in the first media stream by a processing component of the first receiver or transmitter. The second receiver may subscribe to the identified content delay matching stream. The second receiver may receive the content delay matching stream over the network and determine the processing delay from the content delay matching stream. The receiver may cause the second media stream to be delayed in accordance with the processing delay in the first media stream such that the first and second media streams are synchronized.
