[RTP] RTP Server, Audio Multicast and RTP Streaming

The following can be set here.

• RTP Server

Enable RTP, and set the RTSP authentication method and port number.

• Audio Multicast

Make settings for multicast audio transmission.

• RTP Streaming 1 to 5

Make settings for RTP streaming of video, multicasting, and audio transmission.

 

(1) [RTP]

Set RTP to [Disable] or [Enable].

(2) [RTSP Authentication Method]

Set the RTSP authentication method to [Basic Authentication], [Digest Authentication], or [No Authentication].

(3) [RTSP Port]

Set the RTSP port number to 554 or in the range of 1024 to 65535.

Normally [554] (factory default setting) is used.

 

(1) [Multicast Address]

Set the multicast address for audio transmission in the range 224.0.0.0 to 239.255.255.255 (IPv4) or an address beginning with ff00::/8 (IPv6).

To disable Multicast, set to [0.0.0.0] (IPv4) or [::0(::)] (IPv6).

(2) [Multicast Port]

Set the multicast port number for audio transmission to an even number in the range 1024 to 65534.

To disable Multicast, set to [0].

(3) [Multicast TTL]

Set the effective scope of multicast distribution between 0 and 255.

To disable Multicast, set to [0].

The TTL (Time To Live), representing the effective scope of multicast distribution, is decremented each time the signal passes through a router. When the value reaches 0, the signal can no longer be distributed. For example, if TTL is set to [1], multicast distribution is confined to the local segment only and cannot be distributed by the router.

RTP Streaming 1 to 5

You can make settings for each stream, RTP Streaming 1 to RTP Streaming 5, in a 5-session RTP stream distribution.

(1) [Video Size]

Select the video format (JPEG or H.264) and video size of the RTP stream.

The video sizes for JPEG will vary depending on the [Video Size Set] configured in [Video] > [All Videos]. The video sizes for H.264 will be determined according to the [H.264(1)] and [H.264(2)] settings configured in [Video].

In addition, [H.264(1)] and [H.264(2)] cannot be set for multiple RTP streams.

(2) [Frame Rate]

Set the frame rate if the RTP stream is JPEG video.

Cannot be configured for H.264.

(3) [Multicast Address]

Set the multicast address for RTP streaming in the range 224.0.0.0 to 239.255.255.255 (IPv4) or an address beginning with ff00::/8 (IPv6).

To disable Multicast, set to [0.0.0.0] (IPv4) or [::0(::)] (IPv6).

(4) [Multicast Port]

Set the multicast port number for RTP streaming to an even number in the range 1024 to 65534.

To disable Multicast, set to [0].

(5) [Multicast TTL]

Set the effective scope of multicast distribution for RTP streaming between 0 and 255.

To disable Multicast, set to [0].

The TTL (Time To Live), representing the effective scope of multicast distribution, is decremented each time the signal passes through a router. When the value reaches 0, the signal can no longer be distributed. For example, if TTL is set to [1], multicast distribution is confined to the local segment only and cannot be distributed by the router.

(6) [Audio Transmission]

Set RTP streaming audio transmission to [Disable] or [Enable].

Note

• RTP stream URL

rtsp://IP_address:port_number/rtpstream/config1(~5)=r|u|m [=r|u|m] is optional and can be omitted. If specified, specify only one option.

r: Requests RTP over TCP

u: Requests RTP over UDP

m: Requests multicast

Example: RTP streaming 1 request using RTP over TCP rtsp://192.168.100.1:554/rtpstream/config1=r

Note that the actual operation is dependent on the RTP client application, so the URL does not necessarily specify the method used for transmission.

• The video quality and, when H.264 is selected, bit rate control, video size, and frame rate, are determined by the [Video] settings.

• Regardless of the [Server] > [Audio Server] > [Audio Transmission from the Camera] setting, RTP streaming audio will be used.

However, to use audio settings, select [Enable] for [Audio Transmission from the Camera] and make the settings.

• The [Access Control] > [User Authority] > [Video Distribution] and [Audio Distribution] settings are not used for RTP.

• RTP streaming video may not be viewable on systems using a proxy server or firewall. If the video cannot be viewed, contact the system administrator.

• If host access restrictions are applied to a client while it is streaming using RTP over UDP, it may take from a few to several seconds until streaming ceases.
