Streaming (output)

Version V1.62

Cynap has a built-in streaming server which is capable of broadcasting audio and video content over the network.

Prepare the Ethernet connection (wired or wireless) and select the setting on Cynap .

In the settings, you can assign the IP address of the destination (for multicast select: 225.0.0.0 to 238.255.255.255, with all other addresses the stream can be received at the entered destination only, 224.x.x.x and 239.x.x.x are reserved and shouldn't be used), port, resolution, frame rate and streaming interface.

Select the desired settings and start streaming either in the Control Center or by using the Media Cast key on the remote control. Cynap broadcasts the current on-screen content of video and audio to the network.

For RTP, all necessary settings will be provided to the client (player / browser) in a file. RTSP stream is a unicast stream, an end-to-end connection between server and client(s) and all settings are handled automatically. The respective link will be shown below the QR-code by using "Link To Stream" in the Control Center.

RTP stream: e.g.: http://10.0.1.27/stream/stream.sdp or https://10.0.1.27/stream/stream.sdp (use http or https depending on your infrastructure and exchange the example address with the IP address of your Cynap).

RTSP stream: e.g.: rtsp://10.0.1.27/stream (exchange the example address with the IP address of your Cynap ).

Dual Screen mode Moderator, only the released content will be streamed.

Please note, the selected stream format has to be supported by the client (application)used.

Start / Stop Streaming

Use the Control Center to quickly start or stop streaming to the selected network (LAN and/or WLAN, according to the settings).

The content of all active windows will be streamed to the network. When using Moderator Mode, only the released content will be streamed.

A symbol in the top right-hand corner of the main screen indicates the state.

How to get the Stream

Open the Control Center and show the QR code to easily access the stream e.g. when using vSolution App.

When using RTSP, the stream will be sent to all interfaces, but the QR code will show just the selected interface (LAN 1, LAN 2 or WLAN).

By using Media Cast key on the remote control, streaming can be started and stopped quickly.

Security

To increase security, enable Dynamic QR-Code in the settings. Every time a new presentation is started, the suffix of the URL is changed.

E.g.

RTP stream: e.g.: http://10.0.1.27/stream/stream165381.sdp (exchange the example address with the IP address of your Cynap).

RTSP stream: e.g.: rtsp://10.0.1.27/stream872839 (exchange the example address with the IP address of your Cynap).

Link to Stream (QR Code and URL)

Just scan the displayed QR code with your tablet to establish a connection quickly.

Open the respective app on your device and scan the code with your tablet camera when asked.

When the camera cannot be used, enter the displayed URL below the QR code in your app.

Streaming Settings

To select e.g. which clients are able to receive the stream. The selected stream format has to be supported by the client (application) used.

Possible settings are:

Please note

When the vSolution Matrix Master Mode is enabled, the streaming settings are handled automatically and streaming is not available.

RTP Stream

RTSP Stream

Unicast Streaming

Cynap is sending the stream to a single receiver - one to one connection. The IP address of the unique listening receiver has to be set in the streaming settings.

When using RTSP, more than one client can watch the stream over LAN 1, LAN 2 and WLAN simultaneously. Cynap will start a separate unicast stream to each client according to the number of connected clients. The settings will be handled automatically between server and client.

Limitation

In access point mode, UDP-streams over WLAN (Wi-Fi) are limited to unicast.

Multicast Streaming (RTP)

Cynap is sending a stream to a Multicast group - one to many connection. The IP address of the Multicast group has to be set in the streaming settings.

Multicast stream is being sent over LAN 1 interface only.

Note: 224.x.x.x and 239.x.x.x are reserved IP areas and should not be used.

Important:

Activate IGMP snooping to optimize RTP streams.

Normally (without IGMP snooping) a switch will forward a multicast frame to all ports of the switcher (except incoming port). IGMP snooping allows the switcher to forward multicast frames only to receivers, which have joined the particular multicast group. This prevents flooding the network.

Example of Streaming bandwidth in relation to resolution for one stream:

Resolution

Mbit/s

360p

4

540p

6

720p

8.5

1080p

14

Please note

As more clients are connected there is an increased possibility that the network could be overloaded. The maximum number of connected clients depends mostly on the local infrastructure.

Not every device (client) and network infrastructure supports Multicast. In these cases use RTSP instead.

Switching Cynap to standby or ending the presentation closes all connections and stops streaming.
