Preface

This document is for VMS to support JVC new cameras, VN-H37/137/237.

If VMS supports only streaming, i.e. VMS does not have camera setting pages, the chapter "Streaming Protocol" provides how to get stream from a camera.

If VMS have setting page of the camera, focusing on necessary functionalities is recommended. Typical necessary functionalities are Image settings and Encode settings.

Supporting all functionalities of camera will not pay. For example, if VMS does not get multiple streams from a camera, Encode settings can be simple because setting multiple resolution/encode to camera is not required.

1. Streaming Protocol

• Both JVC protocol and standard RTSP/RTP are supported.
• JPEG, H.264 baseline profile, and H.264 high profile are supported. MPEG-4 will be supported in future.
• Maximum resolution is 1920x1080.
• VN-H series can send 3 different resolution streams of JPEG simultaneously.
• VN-H series can send 3 different resolution streams of H.264 simultaneously.
• Sending JPEG stream and H.264 stream simultaneously is supported.

2. JVC Protocol: JPEG Streaming

2.1. Basic Procedures

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

2) The client sends out API.

Example to get JPEG stream encoded by first channel of the camera

GET /api/video?encode=jpeg(1)&framerate=5&server_push=on HTTP/1.1

Host: 192.168.0.2

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

3) The camera returns HTTP response and JPEG stream.

JPEG files in boundary structure will be sent out continuously after HTTP response. Each Content-Length is the size of each JPEG data. Using the size, reading the whole data of each JPEG is possible. HTTP Response and JPEG data sent out by the camera are as follows.

HTTP Response

--fooContent-Type: image/jpegContent-Length: 31614

JPEG (No. 1)

--fooContent-Type: image/jpegContent-Length: 32756

JPEG (No. 2)

...

4) When the client wants to stop current 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 transmission, connect new TCP, and send API with new parameter.

2.2. API Format

Structure

GET	space	API	space	HTTP/1.1	0x0D 0x0A
Host:	space	IP Address of Camera	0x0D 0x0A 0x0D 0x0A

Unlike APIs for getting/setting parameters, Accept line is not required. Basic authentication is also not necessary.

Example

GET /api/video?encode=jpeg(1)&framerate=5&server_push=on HTTP/1.1

Host: 192.168.0.2

Parameter value is indicated using =. Do not insert space before and after =.

Example framerate=1

Parameters are segmented using &. Do not insert space before and after &.

Example encode=jpeg&framerate=5

There is no need to specify all parameters. Default values will be used for parameters that are not specified.

Parameter Description

encode For specifying compression format with channel number. For example, specify as encode=jpeg(1) to get JPEG encoded by channel 1. To know compression format of each channel, open Encoder setting page by IE described in INSTRUCTIONS manual, or issue "encode" API described in later chapter of this document.

framerate For specifying the frame rate. For example, specify as framerate=5 to get at 5 fps. Specify as framerate=-5 to get at 1/5 fps, or in other words, 1 frame in 5 seconds. Selection range for JPEG is as follows. 30, 15, 10, 7.5, 5, 3, 2, 1, 0, -2, -3, -5, -10, -15, -20, -30, -60

When the parameter is specified as framerate=0, the camera sends 1 frame of JPEG data, and disconnect the TCP connection.

server_push For specifying streaming structure. For example, specify as server_push=on to get Server Push

structured JPEG. When framerate=0 is specified, Server Push is disabled even if 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_response line indicates actual parameter.

Example of VN-H137

HTTP/1.1 200 OK

x-vnh37_response: encode=jpeg&framerate=5.0&framesize=1920x1080&server_push=off&ptz_info=off

2.4. Restrictions

Access restriction

The camera has access restriction feature that enables to deny access from a specific IP address. If JPEG is requested from the IP address of access restriction, the camera disconnects the TCP connection after API is sent.

Restriction by maximum bitrate of the camera.

The maximum bitrate of the camera is about 20 Mbps.

Number of clients

The maximum number of clients that can get JPEG stream depends on encode settings and requests from client.

The camera in LAN can be searched by broadcast/multicast packet that has search API.

Search Camera in LAN

Protocol Send broadcast/multicast packet with following text in UDP payload to destination port number 80.

Source port number can be any value. Multicast address is 239.0.255.255.

system.id

Response The camera that received this packet sends unicast udp packet to the source port number of the search packet. UDP payload of response packet has model name, IP address, and subnet mask. The camera

walts 0-0.7 second before sending response to avoid too many responses are sent in short period from many cameras.

Response Example system.id=VN-H37(192.168.0.2/24)&200 OK

7. Using API that Requires Basic Authentication

Basic authentication is required for JVC API explained in Section 7 or later. This section provides general explanation of those APIs.

7.1. Procedure

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

2) The client sends API.

API has following structure.

GET	space		API Characters		space		HTTP/1.1		0x0D 0x0A
Accept:		space		text/plain (or text/html)		0x0D 0x0A
Host:	space		IP Address of Camera		0x0D 0x0A
Authorization: Basic			space	Encoded User Name and Password				0x0D 0x0A 0x0D 0x0A

The following is an example of API for Getting subnet mask of the camera.

Example

GET /api/param?network.interface.subnetmask HTTP/1.1

Accept: text/plain

Host: 192.168.0.2

Authorization: Basic YWRtaW46anZj

Specify the response format by Accept line. Plain text response is returned when this is specified as text/plain. HTML response is returned when text/html is specified. HTML response is returned when Accept is not specified.

These APIs for getting/setting parameters are protected by basic authentication. Authorization line needs to include encoded username and password. There are 3 types of usernames, namely admin, operator and user.

Available APIs are different for each username. Join the user name and the password using a colon, Base64 encode this character string and enter this in the Authorization line.

For example, when

User name admin

Password jvc

then the character string joining the user name and the password with a colon is:

admin:jvc

Base64 encoding of this string yields YWRtaW46anZj. Enter this in the Authorization line. Default password for each username is jvc.

3) The camera returns a response to the client. In the following example, current subnet mask is 255.0.0.0. In addition, 255.0.0.0 is followed by & and 200 OK, indicating that getting parameter is successful.

Example

HTTP/1.1 200 OK

Connection: close

Content-Length: 80

Content-type: text/plain

Date: Fri, 13 MAY 2011 07:33:12 GMT

Server: JVC VN-H37 API Server

network.interface.subnetmask=255.0.0.0&200 OK

4) The client disconnects TCP80 to end the use of API.

Note: APIs for getting/setting parameters are not restricted by the access restriction function.

7.2. Getting Parameter

Specify API in GET line according to the format below when getting a parameter from the camera.

/api/param?ParamA.ParamB.ParamC

It is possible to get multiple parameters at a time. Connect parameters with & Do not insert space before and after &

/api/param?ParamA.ParamB.ParamC&ParamA.ParamD.ParamE

The upper limit of this character string is 1024 bytes. The maximum number of parameters that can be acquired at a time is 15. Status settings, i.e. network.interface.status, network.dns.status, network.ntp.status, etc., can not be acquired at a time.

When acquisition is successfully completed, values will be shown in the body of HTTP response, followed by "&200 OK" message.

Example:

ParamA.ParamB.ParamC=Data&200 OK

When an error occurs, an error code will be returned instead of indicating a value in the body of HTTP response.

Example:

ParamA.ParamB.ParamC&401 Unauthorized

When multiple APIs for getting are performed at one time, a response will be returned for each setting.

ParamA.ParamB.ParamC&200 OK

ParamA.ParamB.ParamD&200 OK

7.3. Setting Parameter

Specify API in GET line according to the format below when setting a parameter for the camera.

/api/param?ParamA.ParamB.ParamC=Data

Parameter values are indicated using =. Do not insert space before and after =.

It is possible to perform multiple settings at a time. Connect parameters with & Do not insert space before and after &.

/api/param?ParamA.ParamB.ParamC=Data&ParamA.ParamB.ParamD=Data

The upper limit of this character string is 1024 bytes. The maximum number of parameters that can be set at a time is 15. Status settings, i.e.network.interface.status, network.dns.status, network.ntp.status, etc., can not be acquired at a time.

Response will be in the following format.

ParamA.ParamB.ParamC&200 OK

An error code will be returned when setting is not properly performed. Example:

ParamA.ParamB.ParamC&401 Unauthorized

When multiple settings are performed at one time, a response will be returned for each setting.

ParamA.ParamB.ParamC&200 OK

ParamA.ParamB.ParamD&200 OK

Time stamp in 8kHz

5) When the client wants to stop current audio transmission, the client disconnects TCP80.

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

29.2. API Format

Structure

GET	space	API	space	HTTP/1.1	0x0D 0x0A
Host:	space	IP Address of the camera	0x0D 0x0A 0x0D 0x0A

Unlike APIs for getting/setting parameters, Accept line is not required. Basic authentication is also not necessary.

Example

GET /api/audio?assured=1&lowdelay=1 HTTP/1.1

Host: 192.168.0.2

Parameter value is indicated using =. Do not insert space before and after =.

Example assured=1

Parameters are segmented using &. Do not insert space before and after &.

Example assured=1&lowdelay=0

There is no need to specify all parameters. Default values will be used for parameters that are not specified.

Parameter Description

assured Recent audio data is stored in internal buffer of the camera. Specify as assured=0 to request for the newest data in the buffer and assured=1 to request for the oldest data in the buffer. Specify as assured=0 to

shorten the audio delay time. To enable stable playback in a network where jitter occurs, it is recommended that this be specified as assured=1. Default value is 1.

lowdelay Specifying as lowdelay=1 disables the Nagle algorithm of TCP, and audio delay time will be shortened. When lowdelay=0 is specified, the Nagle algorithm is enabled and audio delay time will be prolonged. However, transmission overhead will be enhanced. Default value is 1.

29.3. Response

When API is successfully received

The camera will return 200 OK. There is no Content-length field in the HTTP response. The x-vnh57_response line indicates actual parameter.

Example

HTTP/1.1 200 OK

Connection: close

Content-type: audio/ulaw

Date: Tue, 02 Oct 2007 07:33:12 GMT

Server: JVC VN-H57 Network Camera

x-vnh57_response: encode=ulaw&lowdelay=1&assured=1

29.4. Restrictions

Access restriction

The camera has access restriction feature that enables to deny access from a specific IP address. If audio is requested from the IP address of access restriction, the camera disconnects the TCP connection after API is sent.

Restriction by maximum bitrate

The maximum bitrate of the camera is about 20 Mbps.

Number of clients

The maximum number of audio stream is 2, 2 TCP streams or 1 TCP stream and 1 multicast stream. When 2 streams are sent from the camera, new request for audio is disconnected.

30. Sending Audio to the Camera (VN-H57/157WP/257/257VP)

This section describes APIs for audio sending from a client to the camera. Make use of the APIs explained in this section in the way as mentioned in Section 7.

30.1. Procedures

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

2) The client sends out API.

API has following structure.

GET	space		API Characters		space		HTTP/1.1		0x0D 0x0A
Accept:		space		text/plain (or text/html)		0x0D 0x0A
Host:	space		IP Address of the camera		0x0D 0x0A
Authorization: Basic			space	Encoded User Name and Password				0x0D 0x0A 0x0D 0x0A

Refer to Section 5 on details of the Accept and Authorization lines.

The API characters are as follows.

/api/receive?from=network&from.ip=data1&from.protocol=tcp_passive&from.ip_translate=on&to=audio

Example

/api/receive?from=network&from.ip=10.0.0.100&from.protocol=tcp_passive&from.ip_translate=on&to=audio

Specify the client IP address for from.ip=. When from.ip_translate is set to off, the camera will standby to receive audio data from the IP address specified at from.ip. When from.ip_translate is set to on, the camera will ignore from.ip and standby to receive audio data from the source IP address of this API.

2) The camera returns a response.

HTTP/1.1 200 OK

Connection: Keep-Alive

Content-type: text/plain

Date: Fri, 13 MAY 2005 07:33:12 GMT

Server: VN-H57 Network Camera/1.0.0

x-vnh57_response:

from=network&from.ip=10.0.0.100&from.protocol=tcp_passive&from.ip_translate=on&to=audio200 OK

The client may disconnect the TCP80 at this point of time.

3) The client establishes a TCP connection to port number 49298.

4) The client continues to send 512 bytes of u-Law data with a 12-byte header.

0x00000080

Volume of payload (512 for u-Law)

Time stamp in 8kHz

u-Law data (512 bytes)

5) To end, disconnect TCP49298.

30.2. Restrictions

Restrictions on Number of Clients

Only 1 client is allowed to send audio data to the camera. the camera will return an error for this API and TCP will be disconnected when this function is currently in use by another client.

Timing of Data Sending

512 bytes, or in other words, 64 msec of audio data may be sent during each transmission. Send audio data at intervals as evenly as possible. A part of the data may be lost if audio data exceeding 2 seconds are sent to the camera at one time.

31. Getting SD Card data from the Camera via RTSP/RTP

RTSP of the camera is RFC2326 compliant.

31.1. URI

URI for RTSP is

rtsp://ipaddress/PSIA/Streaming/tracks

31.2. Playback control

For Playback control, the messages is used as below,

Control command	Method Header Example
Play PLAY Range	Range:		clock=20120518T135717Z
Pause PAUSE -
KeepAlive GET_PARAMETER -

Specify start time by request header "Range".

For keep-alive control, issue the GET_PARAMETER method in 3 seconds during receiving data.

Keep the message interval is longer than 200 milliseconds.

34.6 Notes

• Enable the JPEG/H.264 frame size that you want in "Basic Settings2" or "Encoding" page of the camera.

• Start Multicast stream on the camera Web page to use Multicast. The ActiveX control does not send request to the camera for starting Multicast stream.

• Set unique Multicast address and port number to each Multicast stream if multiple multicast streams are required in the system.

• Reload of ActiveX control is required to change Multicast property.

36. FAQ

(1) Low Frame rate due to long delay of network

- Causes of Low Frame Rate

During transmission via TCP, the camera sends out the following data by receiving the Ack of TCP. When network delay is long, reception of Ack will be delayed and sending rate will drop. This therefore leads to a drop in the frame rate.

- Countermeasure

This problem can be avoided by receiving via multicast. Multicast uses UDP and Ack does not exist. As such, the sender will be able to continue sending without being affected by network delays.
