XXVI. REAL TIME STREAMING SOLUTION - RTSP PROTOCOL
The current advancements of computer and communications technology,

affords a real time connection to the critical flight data within the black box which

may be established and subsequently routed to remote locations so that the data is

preserved, backup, and/or remotely accessible in real time. Streaming this data from

the QUICK ACCESS RECORDER (QAR), Acquisition Data Unit, or from remote

locations would be desirable in order to preserve this most important flight data.

This application will provide such a method for the preservation and real time

access to this most important data. Not having access to the this critical data is the

most basic shortcoming of the present day flight data recorder systems.

XVII. REAL TIME STREAMING PROTOCOL
The RTSP protocol or a DATA COLLECTION ROUTINE and other proprietary

protocols and software systems can be used to stream data from the FDR, to remote

locations anywhere in the world for immediate access by emergency responders.

The Real Time Streaming Protocol (RTSP) is a network control protocol designed

for use in entertainment and communications systems to control streaming media

servers. The protocol is used for establishing and controlling media sessions

between end points. Clients of media servers issue VCR-style commands, such as

play and pause, to facilitate real-time control of playback of media files from the

server. The transmission of streaming data itself is not a task of the RTSP protocol.

Most RTSP servers use the Real-time Transport Protocol (RTP) in conjunction with

Real-time Control Protocol (RTCP) for media stream delivery, however some

vendors implement proprietary transport protocols. The RTSP server software from

RealNetworks, for example, also used RealNetworks' proprietary Real Data

Transport (RDT)
