A master unit, the topology of which is illustrated in Figure 4, is provided at a suitable location, for example at a stationary location, which ma;y be a bus stop, for exchanging data with the slave assembly illustrated in Figure 2 and 3.
The master unit may have a broadband port 126, forming a master unit communication telemetry system and employing TCIP, LAN, WLAN, l3LUETOOTH, IRDA or broadband cell.
An external device communication port and peripheral VPN 128 provides short range point to point and limited bandwidth communication.
The broadband port station 126 and the external device communication port and peripheral VPN 128 communicates with a main board 130 using a layering routine, flow control and security protocol 131.
The main board 130 includes a CPU 132 with L 1 and L2 cache, a chipset 134, a memory bus and RAM 136, a memory/PCI bridge 138 and a PCI bus and I/O cards 140, and is provided with a data store 142, which may comprise fixed and or removable hard drive, a CDROM
or other suitable storage media. The main board 130 outputs data to an administration video display unit 144, receives input from a keyboard, mouse or other input device 146 and, through a communications network interface 148, communicates with a VPN port 150, remote PC's 152, an emergency services LAN, PSTN or wireless alarm link 154 and an Internet web server 156,, the latter providing live scheduling, moving map display and web content information.
_7_ The operation of the above-described apparatus as follows.
The slave assembly of Figures 2 and 3, provided on the bus, is a quasi-autonomous management module that functions as a full video advertiising streaming and content delivery system, a security management system and recorder and an off board communications control and telemetry system.
The master unit of Figure 4 provides archiving, storage., advance communication functions and CIS/MIS compliant data retrieval. The components shown in Figure 2 which output to the video display unit or units 63 form, with the main board 28 and the data storage, a video streaming system and digital video recorder, and communicate through a common port coupling, for example the wireless network link 78, the hardwire network port 80 or the virtual private network devices port 82, with the master unit of Figure 4, and data is automatically stored in the data store 60 for future retrieval and play back.
This data may, for example, comprise advertising programming, other normal programming and emergency programming for display on the video display unit or units 63 in the bus 10 or 10a.
Video camera data captured and processed by the video cameras 29, the video capture hardware 22, the compression CODEC 26 , which with t'~he main board 28 and the data store 60 form a video recorder system, are transferred from the slave assembly to the master unit for archiving and station use at the site the master unit. Upon completion and verification of data upload to the master unit, video camera information is cleared and the system is reset to a ready status. All operations and data transfer may ~be autonomous or may be manually initiated.
The transfer of information between the slave assembly on the bus and the master unit may conveniently be effected when the bus is docked for servicing or refueling or upon the triggering of an alarm event. When the vehicle is docked, advertising data is thus g downloaded to the slave assembly from the master unit and security information is uploaded from the former to the latter.
The slave assembly receives, digitally records and archives camera data from the video surveillance system, monitors the alarm indicators, i.e. the panic button 48 and the alarm sensors 50 and 52, and responds with an emergency response program as indicated below.
In addition, the slave assembly communicates with the; master unit e.g. by cellular, radio, infra-red, satellite or other communications systems, through the wireless network link 78, the hardwire network port 80 and/or the virtual private network devices port 82, and/or through the radio interface 66.
The slave assembly may be programmed to operate appropriately under three sepaxate conditions which for convenience are referred to in the following description as the Red Condition, the Yellow Condition and the Green Condition.
The Red Condition is initiated by the driver of the bus by actuating the alarm panic button 48, e.g. in response to a severe impact, a fire or other circumstance potentially harmful to life. In response to this condition, the slave assembly automatically transmits an alarm signal to an external emergency response service, through the conveyance communication control and telemetry system, relaying situational and GPS data and simultaneously allocates more resources to surveillance recording by the digital video recorder system and, where permitted by law, activates audio recording through the microphone inputs 40.
Also, in the Red Condition, emergency information andl procedures, where appropriate, are displayed on the video display units.
It is also possible for the video display units to display feeds from the surveillance camera showing that a potential crime is in progress together with an audible alarm or message and a visual warning message, for example "police/fire/ambulance have been notified", to assist in deterring further potentially harmful action.
Under the Red Condition, therefore, the above-described system functions to minimize further immediate risk to the driver and passengers by I>rotecting, diffusing, informing and logging data for future review, identification and evidentiary purposes.
The Yellow Condition may be initiated by the sensors 50 or 52, in response, for example, to excessive noise, vibration, deceleration or acceleration, smoke or contact.
The Yellow I O Condition may also be remotely triggered by the master unit.
Also, the Yellow Condition may be initiated by collision avoidance and emergency manoeuvring, physical contact or accident, forced entry, locked doors, facial or sound recognition, power outage or detection of another lower class emergency situation where silent monitoring is appropriate.
Under the Yellow Condition, the driver is alerted to the situation by an onboard status light or by a display, and the CPU concentrates resources of the slave assembly logging and documenting data from the surveillance cameras through the video camera inputs 20.
In this condition, advertising data or other normal data may continue to be fed to the video display units, but at a reduced rate. Alternatively, display emergency information may be fit to the video display units.
Also an emergency signal may be transmitted to the master unit.
The purpose of the operation during the Yellow Condiition is to record and report on low class emergency incidents while maintaining a silent alarm condition without further contributing further to potential level of panic and confusion in the vehicle.
The normal operation of the system according to the invention during the absence of any emergency, is the Green Condition, in which increased resources of the slave assembly are applied to the display of the advertising or other normall data on the video display units.
The video display units can also display stop, transfer and map information, as desired. By use of a GPS receiver the system can be employed to display advertisements and information corresponding to the geographic location of the bus, thus providing a targeted, context sensitive video program feed to the passengers.
Figure 5 shows a block diagram of a modification of the above-described slave assembly and more particularly includes a digitallanalog video recorder and ancillary hardware 160 which is powered from the power source 52 and serves to receive inputs form the video cameras and the microphones and to output binary IIO alarm control data, serial and digital control and overlay data and video IIO feeds through an extern<~l device layering control, interface and multiplexing module 161 to the mail board 28. A network manager and VPN
162 are also provided between the hardware 160 and the main board 28.
It will be apparent that by the ability of the present system to display advertisements and, thus, to generate revenue, the present system may not only be self financing but may also be a revenue source.
As will be apparent to those skilled in the art, various modifications may be made to the present invention within the present invention.
Thus, while an embodiment of the invention has been described above and illustrated in the drawings as a system installed on a bus, the present invention may be provided in other types of conveyances, including aircraft, taxis, ships and trains, or may be installed in stationary situations, such as retail outlets, hospitals, banks, and railway stations.
~~_. _.-It is also envisaged that the storage of visual information may be effected cumulatively via SCA subcarrier and that the slave units may be daisychained, and also that a plurality of the slave assemblies may be grouped using the VPN port or otherwise. Also, bidirectional streaming with E-COM enabled may be employed and the master assembly or some other remote station may be enabled to access the slave assemlbly at will. Instead of employing the PCI bridge of the above-described embodiment, it is envisaged that other non-legacy hardware may be employed.
A master unit, the topology of which is illustrated in Figure 4, is provided at a suitable location, for example at a stationary location, which ma;y be a bus stop, for exchanging data with the slave assembly illustrated in Figure 2 and 3.
The master unit may have a broadband port 126, forming a master unit communication telemetry system and employing TCIP, LAN, WLAN, l3LUETOOTH, IRDA or broadband cell.
An external device communication port and peripheral VPN 128 provides short range point to point and limited bandwidth communication.
The broadband port station 126 and the external device communication port and peripheral VPN 128 communicates with a main board 130 using a layering routine, flow control and security protocol 131.
The main board 130 includes a CPU 132 with L 1 and L2 cache, a chipset 134, a memory bus and RAM 136, a memory/PCI bridge 138 and a PCI bus and I/O cards 140, and is provided with a data store 142, which may comprise fixed and or removable hard drive, a CDROM
or other suitable storage media. The main board 130 outputs data to an administration video display unit 144, receives input from a keyboard, mouse or other input device 146 and, through a communications network interface 148, communicates with a VPN port 150, remote PC's 152, an emergency services LAN, PSTN or wireless alarm link 154 and an Internet web server 156,, the latter providing live scheduling, moving map display and web content information.

The transfer of information between the slave assembly on the bus and the master unit may conveniently be effected when the bus is docked for servicing or refueling or upon the triggering of an alarm event. When the vehicle is docked, advertising data is thus g downloaded to the slave assembly from the master unit and security information is uploaded from the former to the latter.
The slave assembly receives, digitally records and archives camera data from the video surveillance system, monitors the alarm indicators, i.e. the panic button 48 and the alarm sensors 50 and 52, and responds with an emergency response program as indicated below.
In addition, the slave assembly communicates with the; master unit e.g. by cellular, radio, infra-red, satellite or other communications systems, through the wireless network link 78, the hardwire network port 80 and/or the virtual private network devices port 82, and/or through the radio interface 66.
The slave assembly may be programmed to operate appropriately under three sepaxate conditions which for convenience are referred to in the following description as the Red Condition, the Yellow Condition and the Green Condition.
The Red Condition is initiated by the driver of the bus by actuating the alarm panic button 48, e.g. in response to a severe impact, a fire or other circumstance potentially harmful to life. In response to this condition, the slave assembly automatically transmits an alarm signal to an external emergency response service, through the conveyance communication control and telemetry system, relaying situational and GPS data and simultaneously allocates more resources to surveillance recording by the digital video recorder system and, where permitted by law, activates audio recording through the microphone inputs 40.
Also, in the Red Condition, emergency information andl procedures, where appropriate, are displayed on the video display units.
It is also possible for the video display units to display feeds from the surveillance camera showing that a potential crime is in progress together with an audible alarm or message and a visual warning message, for example "police/fire/ambulance have been notified", to assist in deterring further potentially harmful action.
Under the Red Condition, therefore, the above-described system functions to minimize further immediate risk to the driver and passengers by I>rotecting, diffusing, informing and logging data for future review, identification and evidentiary purposes.
The Yellow Condition may be initiated by the sensors 50 or 52, in response, for example, to excessive noise, vibration, deceleration or acceleration, smoke or contact.
The Yellow I O Condition may also be remotely triggered by the master unit.
Also, the Yellow Condition may be initiated by collision avoidance and emergency manoeuvring, physical contact or accident, forced entry, locked doors, facial or sound recognition, power outage or detection of another lower class emergency situation where silent monitoring is appropriate.
Under the Yellow Condition, the driver is alerted to the situation by an onboard status light or by a display, and the CPU concentrates resources of the slave assembly logging and documenting data from the surveillance cameras through the video camera inputs 20.
In this condition, advertising data or other normal data may continue to be fed to the video display units, but at a reduced rate. Alternatively, display emergency information may be fit to the video display units.
Also an emergency signal may be transmitted to the master unit.
The purpose of the operation during the Yellow Condiition is to record and report on low class emergency incidents while maintaining a silent alarm condition without further contributing further to potential level of panic and confusion in the vehicle.
The normal operation of the system according to the invention during the absence of any emergency, is the Green Condition, in which increased resources of the slave assembly are applied to the display of the advertising or other normall data on the video display units.
The video display units can also display stop, transfer and map information, as desired. By use of a GPS receiver the system can be employed to display advertisements and information corresponding to the geographic location of the bus, thus providing a targeted, context sensitive video program feed to the passengers.
Figure 5 shows a block diagram of a modification of the above-described slave assembly and more particularly includes a digitallanalog video recorder and ancillary hardware 160 which is powered from the power source 52 and serves to receive inputs form the video cameras and the microphones and to output binary IIO alarm control data, serial and digital control and overlay data and video IIO feeds through an extern<~l device layering control, interface and multiplexing module 161 to the mail board 28. A network manager and VPN
162 are also provided between the hardware 160 and the main board 28.
It will be apparent that by the ability of the present system to display advertisements and, thus, to generate revenue, the present system may not only be self financing but may also be a revenue source.
As will be apparent to those skilled in the art, various modifications may be made to the present invention within the present invention.
Thus, while an embodiment of the invention has been described above and illustrated in the drawings as a system installed on a bus, the present invention may be provided in other types of conveyances, including aircraft, taxis, ships and trains, or may be installed in stationary situations, such as retail outlets, hospitals, banks, and railway stations.
~~_. _.-It is also envisaged that the storage of visual information may be effected cumulatively via SCA subcarrier and that the slave units may be daisychained, and also that a plurality of the slave assemblies may be grouped using the VPN port or otherwise. Also, bidirectional streaming with E-COM enabled may be employed and the master assembly or some other remote station may be enabled to access the slave assemlbly at will. Instead of employing the PCI bridge of the above-described embodiment, it is envisaged that other non-legacy hardware may be employed.
