Pan position	16	digipan = 123	Indicates pan position in pixels from 0 to 1278.
Tilt position	17	digitilt = 123	Indicates tilt position in pixels from 0 to 958.
Zoom position	17	digizoom = 1.23	Indicates zoom value from 1.00 to 8.00.
Preset Posision	15	position = 19	Indicates preset position number after moving to
Number			preset position. In other cases, position = NA.

4. JVC Protocol: MPEG-4 Streaming

4.1.Basic Procedures

1)The client establishes a TCP connection to port number 80.

2)The client sends out API.

Example

GET /api/video?encode=mpeg4 HTTP/1.1<CRLF>

Host: 192.168.0.2<CRLF><CRLF>

Note <CRLF> denotes the line feed code (0x0D, 0x0A).

3) The camera returns HTTP response and MPEG-4 stream.

HTTP Response and MPEG-4 stream sent out by the camera are as follows.

HTTP Response

VOP of MPEG_4 (First Frame)

VOP of MPEG-4 (Second Frame)

,,,

4) When the client wants to stop current MPEG-4 transmission, the client disconnects TCP80.

The camera does not accept further API via current TCP that is used for H.264 transmission. To change parameter, disconnect current TCP to stop the MPEG-4 transmission, connect new TCP, and send API with new parameter.

4.2.API Format Structure

GET	space	API	space	HTTP/1.1

Host:	space	IP Address of Camera	0x0D 0x0A 0x0D 0x0A
