HELO Plus H.264 Streaming and Recording Encoder v1.0 31 www.aja.com
RTSP
RTSP is a pull protocol and is usually used when a viewer on a computer is using a
client application like VLC to watch a stream. In this case HELO Plus always has the
content ready and available (if it is actively streaming), but the client initiates and
ends the viewing session.
NOTE: HELO Plus supports one RTSP session. Either stream 1 or stream 2 can be RTSP,
not both. That one session can support up to 10 clients, but those 10 clients are
shared between the RTSP and HLS streaming types. For example, stream 1 can
have two RTSP clients and stream 2 can have eight HLS clients, or five clients for
each, etc.
The following parameters are available when RTSP is selected:
• RTSP Stream Name - This name becomes part of the connection URL.
• RTSP Port - RTSP streaming is performed over incoming TCP connections to
HELO Plus. Specify the port on which the incoming connection should be
made by using the RTSP Port sliding control. The default port number used is
554.
NOTE: For RTSP, to avoid failure, the selected incoming port must not be port 80 or 443
because they conflict with HELO Plus's web interface http and https services.
• RTSP Authentication - Select from
None
(factory default, no user name or
password required),
Basic
(username and password, but insecure unless used
with SSL), or
Digest
(username and password, securely encrypted). If not set
to None, the user must set a username and password. Viewers won't be able
to access the RTSP stream without them.
RTP-TS
RTP-TS is a push protocol, typically used for multicast applications. No CDN is
required. RTP (Real-time Transport Protocol) requires a numeric IP address and
port number. Recipients of the stream have to have access to the destination port
and use a video player like VLC. The following parameter is available:
• RTP-TS Destination URL - Defines the RTP-TS destination URL using a numeric
IP address and port number.
The RTP protocol uses outgoing UDP ports for streaming. The port number must
be specified in the streaming URL. For example, to specify port number 5432, the
URL would follow this format:
rtp://10.0.0.1:5432
NOTE: RTP-TS and UDP-TS are basically identical, except for video player compatibilities.
UDP-TS
UDP-TS is a push protocol, typically used for multicast applications. No CDN is
required. UDP-TS (User Datagram Protocol Transport Stream) require a numeric
IP address and port number. UDP-TS is a raw MPEG transport stream sent out
through UDP packets. Recipients of the stream have to have access to the
destination port and use a video player like VLC. The following parameter is
available:
• UDP-TS Destination URL - Defines the UDP-TS destination URL using a
numeric IP address and port number.
The RTP protocol uses outgoing UDP ports for streaming. The port number must
be specified in the streaming URL. For example, to specify port number 5432, the
URL would follow this format:
udp://10.0.0.1:5432
