Preface This document is for VMS to support JVC new cameras, VN -H37/137/237. If VMS supports only streaming, i.e. VM S does not have camera setting pages, the chapte r "Streaming Protocol" provides how to get strea m from a camera. If VMS hav e setting page of the camera , focusing on nece ssary functional ities is recommended.

1. Streaming Protoc ol - Both JVC pr otocol and sta ndard RTS P/RTP are sup ported. - JPEG, H.264 baseline pr ofile, and H.26 4 high profile are supported. M PEG-4 wi ll be supporte d in future. - Maxim um resolution is 19 20x1080. - VN-H series ca n send 3 d ifferent resolu tion stream s of J PEG sim ultaneously.
4) When the client wants to stop curren t JPEG transmission, the client disconnects TCP80. The camera does not accept further API via current TCP that is used for JPEG transmission. To change parameter, disconnect current TCP to stop the JPEG transm ission, connect new TCP, and send API with new parameter.
structured JPEG. When framerate=0 is specified, Server Push is disabled even i f server_push=on is specified. 2.3. Response When API with server_push=on is successfully received. The camera will return 200 OK. The x-vnh37_respo nse line indicates actual parameter.
Refer the instruction manual for detailed infomation. 2.5. JPEG File Format Sent Out by the came ra JPEG file from the camera is JFIF compliant a nd consist of the following.
Example: W hen width=640, the 13-byte area w ill be written as follows. 3. JVC Protocol: H.2 64 Streaming 3.1. Basic Procedures 1) The client establishes a TCP connection to port num ber 80. 2) The client sends out API. Example to get H.264 high profile st ream encoded b y first chan nel of the ca mera GET /api/video?encode=h264(1) HT TP/1.
Unlike APIs fo r g etting/setting p arameters, Accept line is not requi red. Basic a uthentication i s also no t necessary. Example GET /api/video?encode=h264(1) HT TP/1.1<CRLF> Host: 192.168.0.2<CRLF><CRLF> Parameter value is indicated using =.
H.264 str eam form the camera is sequence o f I Pi cture and P Pi cture. Ratio of I Picture a nd P Picture depends o n I-Frame interval setting. Encode page of W eb has the setting.
Pan position 16 digipan = 123 Indicates pan p osition in pi xels from 0 to 1278. Tilt position 17 digitilt = 123 Indicates tilt pos ition in p ixels from 0 to 9 58.
Unlike APIs fo r g etting/setting p arameters, Accept line is not requi red. Basic a uthentication i s also no t necessary. Example GET /api/video?encode=mpeg4 HTT P/1.1<CRLF> Host: 192.168.0.2<CRLF><CRLF> Parameter value is indicated using =.
Ratio of I-VOP and P-VOP depends on I-Frame inte rval setting. Encode page of Web has the setting. First VOP can be I-VOP or P-VOP. If clie nt want to decode from I-VOP, please skip P-VOP and wait first I-VOP. Example of MPEG-4 Stream HTTP response P-VOP P-VOP P-VOP VOL I-VOP P-VOP ~ There are VOL, Userdata1, GOV and Us erdata2 before each I-VOP.
5. RTSP/RTP 5.1. URI RTSP of the cam era is RF C2326 com pliant. Three encoders can be ena bled in the cam era at its m aximum . Each encoder's U RI for RT SP is: Encoder Chan nel URI of RT SP 1 .
