Web Interface –Channel Setup Output Protocol
Channel Setup - Output
Important: The selection of the output stream protocol dynamically changes the available options for video and audio
encoding. Therefore, the streaming protocol must always be set before proceeding to the video and audio settings.
Output Transport Stream
Auto Start auto start of encoder when input video is detected
Protocol streaming protocols and native integrations - see pages 15 through 18 for setup information
AUX File archive a copy of your stream in .mp4 –see page 14 for additional information
Protocol: When sending media over networks, protocol can mean Transport Protocol or Payload Format. For instance, TS over UDP
refers to using the MPEG-TS payload format to deliver media via the UDP protocol. Selecting which protocol to use will dictate several
other settings within the video and audio encoding sections. Selecting RTMP/RTMPS will limit the “codec” setting to “H.264”. Selecting
“TS over RTP” allows the selection of both “H.264” and “HEVC” for codec. Select “Protocol” first when setting up an encoder output and
the rest of the Video and Audio settings will conform to your Protocol selection.

UDP is a connectionless protocol with minimal mechanisms. It doesn't require recipients to let the sender know that all data packets
have arrived, which can make it unreliable. This protocol is stateless and ideal for transmitting data to large numbers of clients. UDP
features multicast support for service discovery and broadcasting. Its low rate of retransmission delays makes it the perfect match
for real-time applications
RTMP is a legacy protocol developed by Adobe® to transfer audio and video files between a streaming server and the Adobe Flash
Player. With the phasing out of Flash, it has shifted its primary use case away from viewer-facing content delivery and toward
ingesting live streams through RTMP-enabled encoders.

RTP is designed for end-to-end, real-time transfer of streaming media. The protocol provides
facilities for jitter compensation and detection of packet loss and out-of-order delivery, which are
common especially during UDP transmissions on an IP network.
SRT Mode ‘Listener’: The “agent” waits to be contacted by any peer caller. Note that a listener can
accept multiple callers, but Talon does not support this ability; after the first connection, it no longer
accepts new connections.
SRT Mode ‘Caller’: The “agent” (this application) sends the connection request to the peer, which must be listener, and this way it
initiates the connection.
SRT is known for its security, reliability, compatibility, and low-latency streaming it is the preferred protocol for members of the SRT
Alliance. This protocol does not rely on a single codec, which allows developers to pair it with any audio and video codecs they desire.

Web Interface –Transport Protocols RTSP, WebRTC
Channel Setup –Transport Protocols
WebRTC
Due to the open-source nature of webRTC, this is only available though custom integrations
currently supporting:
WebRTC is an open-source project that delivers video streams to viewers with real-time latency. Initially developed for text-based chat
apps and VoIP usage.. The WebRTC protocol is a low-latency streaming solution using WHIP.
RTSP (Real-Time Streaming Protocol)
Mount Point mount point port
Host Port host destination port
Authentication enable/disable stream authentication
User username for authentication
Password username for authentication
RTSP is a legacy protocol, it cannot transmit live streaming data alone and require RTSP servers to work together with RTP and other
protocols to accomplish their streaming tasks. It can deliver low-latency streaming to a select group of small audiences from a
dedicated server.

Password/Secret this is the “Zixi Secret”. By default, any publish point in Broadcaster can be accessed by any encoder.
Zixi Broadcaster can provide a Feeder with a password which gives that encoder priority over any other
encoder connected to that publish point. If an encoder with the password attempts to connect, the
publish point will remove any other encoder connected to it and replace it with the password protected
version.
Encryption enable/disable AES-128, AES-192 or AES-256 stream encryption
Encryption Key cut and paste the encryption key provided by your Zixi Broadcaster in the allotted space.
Video PID the Default PID is 600. Any ID greater than 0 but less than 8192 may be used.
PMT PID the default PMT PID is 10. Other values can be used where specified by the transport stream.
Server Address IP address of the stream destination
Server Port port of the stream destination. The default is 2088
Session ID unique name of the stream. This name can be created by the user
or assigned by the Zixi Broadcaster.
Latency the latency setting or “smoothing” as it is sometimes referred to
in Zixi, enables transmission of the output at the correct rate.
Required when the receiving device is sensitive and can’t lock
onto the stream. Default setting is 100ms. The available range is
between 100 and 1000ms.
Max Bitrate specify the maximum expected bitrate for memory allocation.
Recommended: For CBR start with 10% higher than the stream
bitrate. For VBR use 2X the actual bitrate, which will prevent
buffer overruns (especially with VBR streams). Default: 5000.
Note – Overflows will typically occur when the Max Bitrate isn’t
sufficient.
Min Bitrate currently, min bitrate is not configured.
While not a protocol, Zixi defines itself as a “software-Defined video Platform (SDVP). Talon’s implementation was built upon the Zixi
SDK and serves as a Zixi Feeder. It can deliver to a Zixi Broadcaster, which can deliver to a decoder. The Talon cannot deliver Zixi
directly to another decoder.

Important: The selection of the output stream protocol dynamically changes the available options for video and audio
encoding. The options outlined in this chapter are based on UDP and might slightly differ from your settings.
Source select your input video source
Output Resolution for best quality and lowest latency it is recommended to match your input and output resolutions
Framerate for best quality and lowest latency it is recommended to match your input and output framerate
Codec select between HEVC (H.265) and AVC (H.264). Note that not all streaming protocols support HEVC.
Target Bitrate Target Bitrate is set based on the rate control method used. For CBR, the Target Bitrate equals the
bitrate to maintain throughout the encode. For VBR, it is the rate you want to average.
Maximum Bitrate maximum Bitrate is only enabled when VBR is selected. Maximum bitrate to be >= ‘Target Bitrate’
Encoding Profile different profiles are available depending on the codec:
HEVC - Main, Main 10, Main 4:2:2 10
AVC - Baseline, Main, High, High-10, High 4:2:2
Color Processing for best quality and lowest latency it is recommended to match your input and output color space.
The options change depending on the selected codec and encoding profile.

Rate Control select between CBR, VBR, QP and Low Latency. Constant QP means that the bitrate can vary greatly to
achieve the set QP. This can result in wild fluctuations of bitrate and is not recommended for live streaming.
Deinterlacing select the deinterlacing mode to encode progressive of an interlaced video input signal.
QP Mode ‘Auto’ or ‘Uniform’, default is ‘Auto’
Max QP Default ‘36’, a higher number results in a lower bitrate and lower quality (delta between max QP and
min QP should always be <12). Maximum is 51.
Min QP Default ‘24’, a higher number results in a lower bitrate and lower quality (delta between max QP and
min QP should always be <12).
GOP Mode Low Delay P/Low Delay B/Basic (IPPP)/Basic-B/Adaptive.
Choose ‘Low Delay P’ if you are unfamiliar with GOP settings.
B-Frames Number of B-frames between I-frames. 0 –4. This feature is only available for certain GOP modes.
GOP Size 5 –240 frames, choose twice your encoding framerate as default
Metadata OFF, CEA708, SMPTE-2038
QP: The Quantization Parameter controls the amount of compression for every macroblock in a frame. Large values mean that
there will be higher quantization, more compression, and lower quality. QP ranges from 0 to 51.
GOP: GOP parameters define the basic pattern of the video stream in terms of how the encoder uses I-, P-, and B- frames.
B-Frame: A compressed video frame which is reconstructed based on its differences from the previous and the subsequent frame
