XXXII. VoIP AND VIDEO SURVEILLANCE

VoIP is short for Voice over Internet Protocol. Voice over Internet Protocol is a category

of hardware and software that enables people and companies to use the Internet as the

transmission medium for telephone calls by sending voice data in packets using IP rather than

by traditional circuit transmissions of the Public Switch Telephone Network (PSTN)

The Session Initiation Protocol (SIP) is a signaling communications protocol, widely

used for controlling multimedia communication sessions such as voice and video calls over

Internet Protocol (IP) networks. The protocol defines the messages that are sent between

endpoints, (such as cameras, soft phones, ip phones, etc) which govern establishment,

termination and other essential elements of a call. SIP can be used for creating, modifying and

terminating sessions consisting of one or several media streams. SIP can be used for

two-party (unicast) or multiparty (multicast) sessions. Other SIP applications include video

conferencing, streaming multimedia distribution, instant messaging, presence information, file

transfer, fax over IP and online games.

VoIP is an excellent technology for connecting to the camera surveillance system

proposed in this invention. In simple terms, endpoints can be established such that

investigators and other authorities can review security camera on board the flight, and even

establish two way communications between the cameras and a remote source connected to

the VoIP network.

Although VoIP is not a necessary element in establishing communications to remote

camera system in this invention, it is discussed because VoIP would in fact be a viable

solution to accessing the on board video system discussed in this invention if satellite internet

services are implemented in the solution. This would make it possible for investigators to not

only view the cockpit and passenger cabin of the aircraft, but it would be possible to actually

communicate with a live person near those cameras in the event of an emergency..
