## Background
BACKGROUND OF THE INVENTION
Embodiments of the present invention relate to video transmission and in particular to a mobile video recording system that connects to different wireless networks.
Mobile video recording and storage devices may connect to several network sites throughout an operational day. The networks may implement different device identification methods, so methods are needed that allow the mobile devices to communicate with each of the networks. One conventional method of identifying mobile devices on a network is to provide the device with a static network address. In such a case, each separate network would need to have a way of tracking each mobile device that may be connected to the network, even if the device is not presently connected to the network. In addition, each separate network would have to be configured to support identification of static network addresses.
Another conventional method of identifying mobile devices on a network includes use of a Dynamic Host Configuration Protocol (DHCP) in which a temporary identification number is assigned to devices when they log in to a network. The DHCP utilizes a domain name system (DNS) which manages the assignment of the temporary identification numbers to the devices. Utilizing the DNS, network devices are able to find other network devices by searching for a machine name without having to keep track of the network devices' temporary identification numbers. However, introduction of a DNS requires additional hardware and manpower to manage the system.

DETAILED DESCRIPTION OF THE INVENTION
Mobile video recording systems connect to various networks over a period of time. Embodiments of the invention provide for systems, methods and devices to assign dynamic addresses to the mobile video recording systems and to keep track of current dynamic addresses by video analysis software in a video analysis system.
FIG. 1 is a diagram of a video recording and transmission system 100 according to an embodiment of the invention. The system 100 includes a mobile video recording system 110, a video analysis system 120a and a wireless communications system 130a. The mobile video recording system 110 may be mounted in a vehicle, may be part of a handheld device, or may include any other manner of recording and storing video in a mobile environment. The mobile video recording system 110 includes a camera 111 to capture video images, a video receiver 112 to receive the video images and process the video images, such as by compressing, formatting, organizing the video images, or performing any other function on the video images. While the mobile video recording system 110 of FIG. 1 is illustrated as including a camera 111 for recording images, embodiments of the invention also encompass a mobile video system that may not have a camera for recording the video, but instead receives and stores video from another device or system.
The mobile video recording system 110 also includes video storage 113 to store the video images. The video storage 113 may include any type of memory, including volatile memory non-volatile memory, disk memory, solid state memory, etc. The mobile video recording system 110 also includes device data 114, such as a unique identifier 115 of the mobile video recording system 110 and a dynamic network address 116 of the mobile video recording system 110. The unique identifier may be a name of the mobile video recording system 110 that readily identifies the mobile video recording system 110. For example, if there are twenty vehicles in a fleet, and each vehicle has installed a mobile video recording system 110, the names of the mobile video recording systems 110 may be “Vehicle 1” through “Vehicle 20.” In embodiments of the invention, the unique identifier 115 does not change over time as the mobile video recording system 110 connects to different wireless communication systems. On the other hand, the dynamic network address 116 may change each time the mobile video recording system 110 communicates with a different wireless communications system.
The mobile video recording system 110 also includes a wireless transmitter/receiver 117, which may include an antenna and supporting circuitry to process data for wireless transmission and to process data that is received wirelessly. The wireless transmitter/receiver 117 may include program code configured to control a processor to generate a unicast signal, a multicast signal, or a broadcast signal to devices on a network to which the mobile video recording system 110 is connected. The unicast, multicast and broadcast signals may include identification data, including the unique identifier 115 and dynamic network address 116, as well as a device type, capability sets of the mobile video recording system 110, health and diagnostic data, and any other data. In one embodiment, the unicast, multicast or broadcast signal is re-transmitted by the mobile video recording system 110 at regular intervals.
The video analysis system 120a may be a computer including one or more processors, memory, logic circuitry and other circuitry. The video analysis system 120a is a stationary device, structure, apparatus or system, or a device that is configured to operate when stationary and is not configured to operate while moving from one place to another. The video analysis system 120a includes video analysis software 121, which may be stored in memory of the video analysis system 120a and executed by a processor of the video analysis system 120a. The video analysis software 121 includes a video receiving unit 122 configured to receive and process video from a source external to the video analysis system 120a, a video analysis unit 123 to analyze content of the video, and a video playback unit 124 to control playback of the video. For example, in one embodiment a video is received from a source external to the video analysis system 120a and the video is played back on the video playback unit 124 to generate a display visible by a user. The user may then perform operations, including playback and transmission of the video, on the video analysis system 120a. 
The video analysis system 120a also includes a mobile device communications unit 125. The mobile device communications unit 125 includes a user input unit 126 configured to generate a display including device selection icons for use by a user. The mobile device communications unit 125 also includes a table 127 that matches a unique identifier, such as a device name, with a dynamic network address, such as a dynamic Internet protocol (IP) address. When a user selects a device icon in the user input 126, the mobile device communications unit 125 initiates communications with the corresponding mobile video recording system 110 via a wireless communications system 130a. The wireless communications system 130a may be a wireless communication network or may be part of a larger wireless communication network.
The wireless communication system 130a includes a dynamic network address request/receiving unit 131 to request and/or receive the unique identifier and dynamic network address information from the mobile video recording system 110. The wireless communication system 130a also includes a wireless communication unit 132, such as an antenna.
Operation of the video recording and transmission system 100 will be described with respect to FIGS. 1 and 2. When the mobile video recording system 110 comes within range of the wireless communications system 130a in block 201, the wireless transmitter/receiver 117 of the mobile video recording system 110 may transmit identification data to the wireless communication system 130a in block 202. If the video recording system 110 requires assignment of a dynamic Internet protocol (IP) address, transmitting the identification information includes a request for the dynamic Internet protocol (IP) address. The wireless communication system 130a receives the information and request in block 203 and the dynamic network address request/receiving unit 131 of the wireless communication system 130a supplies a dynamic network address to the mobile video recording system 110 in block 204 to permit the mobile video recording system 110 to communicate with other devices connected to the wireless communication system 130a. The mobile video recording system 110 receives the dynamic network address in block 205 and stores the dynamic network address 116.
In block 206, the mobile video recording system 110 transmits a unicast, multicast or broadcast signal over the wireless communication system 130a to the video analysis system 120a. The unicast, multicast or broadcast signal includes identification information including a name or identification number of the mobile video recording system 110 and the dynamic network address of the mobile video recording system. The mobile video recording system 110 may also transmit information regarding the device or system type of the mobile video recording system 110, capability sets of the mobile video recording system 110, health and diagnostic data, and any other data. In embodiments of the invention, the name of the mobile video recording system 110 is a static and unique identifier that does not change as the mobile video recording system 110 connects to different wireless communication systems over time.
The video analysis system 120a receives the identification information from the mobile video recording system 110 in block 207, and in block 208 the video analysis system 120a associates the received dynamic network address with the name of the mobile video recording system 110 in memory of the video analysis system 120a. In one embodiment, the video analysis system 120a maintains a table of the names of each mobile video recording system 110, whether or not the listed mobile video recording system is presently connected to a wireless communication system. The table may include the last-received dynamic network address for the listed mobile video recording systems, or the system may delete dynamic network addresses for the listed mobile video recording systems based on determining that the systems have disconnected from a wireless communication system. When the mobile video recording system 110 provides a dynamic network address to the video analysis system 120a, the video analysis system 120a updates the table by over-writing a previously-provided dynamic network address, or by entering the dynamic network address in an empty cell associated with the mobile video recording unit 110, based on the name provided by the mobile video recording unit 110.
In block 209, a user may select a name of a mobile video recording unit 110 to perform an action, such as downloading video, analyzing downloaded video, receiving information regarding the status of the mobile video recording system 110 or performing any other function. The user may select the name of the mobile video recording unit 110 by typing the name into a user interface generated by the video analysis software 121 or by selecting the name from a list of names provided by the video analysis software 121, for example. In one embodiment, the user interface includes an electronic display of information on a computer display, and the selection includes manipulation of a user input, such as a mouse, touch-screen, keyboard, or any other selection mechanism.
Based on the user selection of the name in block 209, the video analysis software 121 refers to the table 127 to obtain the dynamic network address of the mobile video recording system 110 in block 210. In block 211, the video analysis system 120a transmits a communication to the mobile video recording system 110 to perform the requested action. In FIG. 2, the requested action is described as a request to transmit video; however, embodiments of the invention encompass any requested action, including requests for data or commands to control operation of components of the mobile video recording system 110.
In block 212, the mobile video recording system 110 receives the request via the wireless communication system 130a. In block 213, the mobile video recording system 110 responds to the request by transmitting the requested video to the video analysis system 120a which receives the video in block 214. In block 215, the video analysis system 120a associates the received video with the name of the mobile video recording system 110 in memory of the video analysis system 120a, and in block 216, the video analysis system analyzes the video, or a user analyzes the video using the video analysis system 120a. 
During the course of time, such as over the course of hours of a day, or over the course of days, the mobile video recording system 110 may move around geographically and come into communication with multiple wireless communication systems, represented by the wireless communication systems 130a and 130b of FIG. 1. Each wireless communication system 130a and 130b may be within communications range of different video analysis systems. For example, in FIG. 1, the wireless communication system 130a provides a communications network for the video analysis systems 120a and 120b, such that a mobile video recording system 110 connected to the wireless communication system 130a may access each of the video analysis systems 120a and 120b. The wireless communication system 130b provides a communications network for the video analysis system 120c, such that a mobile video recording system 110 connected to the wireless communication system 130b may access only the video analysis system 120c. In one embodiment, as illustrated by the dashed arrow of FIG. 1, multiple video analysis stations 120a and 120c may also be connected to each other via communications channels other than the wireless communication systems 130a and 130b, such as via telephone, Internet, satellite or other networks, to transmit information between video analysis systems.
Referring to FIG. 2, when the mobile video recording system 110 moves into range of another wireless network, such as the wireless communication system 130b of FIG. 1, the process of transmitting identification information (blocks 202 and 203) and transmitting a new dynamic network address (block 204) are repeated with each separate wireless communication system.
While embodiments of the invention have been described with respect to FIGS. 1 and 2, it is understood that these figures are provided only to illustrate example embodiments, and embodiments of the invention encompass variations of the systems and methods shown, including systems and methods having additional components and fewer components. For example, while FIG. 1 illustrates a mobile video recording system 110 having one camera 111, one video receiver 112, one video storage 114, one block of device data 114 and one wireless transmitter/receiver 117, embodiments of the invention encompass mobile video recording systems having any number of these components. In an embodiment in which the components are installed in a vehicle, the vehicle may include multiple cameras and multiple DVR devices, and each DVR device may have a separate unique identifier, such as a name, and each may be assigned a separate dynamic network address.
In addition, while embodiments of the invention have been described with respect to video recording, analysis and transmission, embodiments of the invention also encompass audio recording, analysis and transmission. The audio may be transmitted together with video, or the audio may be recorded, transmitted and analyzed with no video.
According to embodiments of the invention, a video analysis system, computer or software run on the system or computer provides to the user or system a list of names of mobile video (or audio) recording or storage devices. As the mobile video or audio recording or storage devices come into communication with different wireless communication systems over the course of time, the mobile video or audio recording or storage devices are provided with a dynamic network address corresponding to the wireless communication system to which the mobile video or audio recording or storage device is presently connected. The video analysis system, computer or software associates the current dynamic network address with the name of the mobile video or audio recording or storage device. A user or system may select the name of the mobile video or audio recording or storage device, and the video analysis system, computer or software automatically accesses the associated dynamic network address to permit communication with the mobile video or audio recording or storage device without the need for a user to remember a dynamic network address, without the use of a DNS server and without the use of a static network address for the mobile video or audio recording or storage device.
While the invention has been described in detail in connection with only a limited number of embodiments, it should be readily understood that the invention is not limited to such disclosed embodiments. Rather, the invention can be modified to incorporate any number of variations, alterations, substitutions or equivalent arrangements not heretofore described, but which are commensurate with the spirit and scope of the invention. Additionally, while various embodiments of the invention have been described, it is to be understood that aspects of the invention may include only some of the described embodiments. Accordingly, the invention is not to be seen as limited by the foregoing description, but is only limited by the scope of the appended claims.
