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.
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.
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.
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).
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.
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:
Enable / disable Streaming. When disabled, the Streaming button will be not displayed in the Control Center and will be not available with Media Cast key).
Resolution of the network stream, up to 1080p (note resulting network traffic)
Frame Rate, higher frame rate results in more network traffic (LOW=10, MEDIUM=20, HIGH=30)
Enable / disable Dynamic QR-Code to allow random URLs to receive the stream (QR-Code and URL changes with every new presentation)
Enable / disable RTP Stream (RTSP cannot be used simultaneously)
Time To Live, to specify how many hops (routers) the packet can elapse before the data will be discarded.
This setting is available for RTP only.
IP address for UDP stream, the description below the address field indicates the used range.
225.x.x.x to 238.255.255.255 are valid multicast addresses and supported on the LAN interface only (addresses with first octet 224. and 239. are reserved and shouldn't be used).
To use unicast, enter the destination IP address (IP address of the receiving device like your PC).
This setting is available for RTP only.
Port where the stream will be sent over the network (range 8800 ~ 9000, even numbers allowed only).
The audio port used will be displayed for information, it cannot be changed separately (it is always 2 ports higher).
This setting is available for RTP only.
Enable/disable RTSP Streaming (RTP cannot be used simultaneously).
Cynap is sending several streams (unicast streams) depending on the number of connected clients. This way, several clients, also connected to the built-in access point, can receive the stream.
All settings will be handled automatically between Cynap and the client. The protocol used can be UDP and/or TCP.
Select the network interface (LAN 1, LAN 2 or WLAN) for the displayed QR-Code.
Please note
When the vSolution Matrix Master Mode is enabled, the streaming settings are handled automatically and streaming is not available.
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.
In access point mode, UDP-streams over WLAN (Wi-Fi) are limited to unicast.
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.

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.
