Too network interface is transferred to cache logger [2], and the cache logger [3] is carried out at data to the HD video data of reception
Reason, the data card [3] are attached by SATA2.0 interfaces and cache logger [2], receive cache logger [2] processing
HD video information afterwards；
Cache logger [1] data processing method is as follows：
Step 1: establishing UDP ethernet ports, and IP address and port numbers are set；TCP ethernet ports are established, and are set
Put IP address and port numbers；
Step 2: TCP ethernet ports are connected with network camera instrument, cache logger by TCP ethernet ports to
Network camera instrument sends TEARDOWN message, and network camera instrument receives feedback acknowledgment information after TEARDOWN message；
Step 3: cache logger sends SETUP message, network shooting by TCP ethernet ports to network camera instrument
Instrument receives feedback acknowledgment information after SETUP message；
Step 4: cache logger sends PLAY message, network camera instrument by TCP ethernet ports to network camera instrument
Receive feedback acknowledgment information after SETUP message；
Step 5: cache logger [2] receives the output data of network camera instrument [1], network by UDP ethernet ports
The output format of video camera [1] is H.264 naked bit stream data；Cache logger [2] is according to RTSP agreements to the data that receive
Parsing, and add packet header and lapse of time write-in data card [3].
In step 5, when occurring more than 3 seconds and not receiving data, step 2 is returned to.
Cache logger [2] can carry out the camera data of reception data processing, conversion by data processing method
The data format that need to be stored into cache logger.
When system works, completing collection, compression and the coding of Airborne Video System information by network camera instrument [1] first turns into
H.264 video format, the RTSP agreements that cache logger [2] receives network camera instrument [1] transmission by Ethernet interface are transmitted
H.264 data；Data processing and packing are carried out by software algorithm, the data after processing are finally passed through into SATA2.0 interfaces
Write in data card [3].
Beneficial effect：HD video recording method of the present invention based on RTSP agreements, can solve the problem that and be based on
Vxworks real time operating systems can not directly support RTSP agreements to transmit, convenient record H.264 regarding based on the transmission of RTSP agreements
Frequency information, meet the requirement that user records to high-resolution quality video.
Brief description of the drawings
Fig. 1 is the HD video recording method theory diagram based on RTSP agreements；
Fig. 2 is cache recorder data processing method；
Wherein, 1- network camera instruments, 2- caches logger, 3- data cards.
Embodiment
The present invention is described in further detail below in conjunction with the accompanying drawings.
Referring to Fig. 1, present invention one kind be based on RTSP agreement HD video recording methods, including network camera instrument [1], soon
Logger [2] and data card [3] are taken, the network camera instrument [1] completes collection, compression and the coding of Airborne Video System information, and
Cache logger [2] is transferred to by Ethernet interface, the cache logger [3] enters line number to the HD video data of reception
According to processing, the data card [3] is attached by SATA2.0 interfaces and cache logger [2], receives cache logger [2]
HD video information after processing；
Cache logger [1] data processing method is as follows：
Step 1: establishing UDP ethernet ports, and IP address and port numbers are set；TCP ethernet ports are established, and are set
Put IP address and port numbers；
Step 2: TCP ethernet ports are connected with network camera instrument, cache logger by TCP ethernet ports to
Network camera instrument sends TEARDOWN message, and network camera instrument receives feedback acknowledgment information after TEARDOWN message；
Step 3: cache logger sends SETUP message, network shooting by TCP ethernet ports to network camera instrument
Instrument receives feedback acknowledgment information after SETUP message；
Step 4: cache logger sends PLAY message, network camera instrument by TCP ethernet ports to network camera instrument
Receive feedback acknowledgment information after SETUP message；
Step 5: cache logger [2] receives the output data of network camera instrument [1], network by UDP ethernet ports
The output format of video camera [1] is H.264 naked bit stream data；Cache logger [2] is according to RTSP agreements to the data that receive
Parsing, and add packet header and lapse of time write-in data card [3].
In step 5, when occurring more than 3 seconds and not receiving data, step 2 is returned to.
