RTP streaming, available with the release of Cablecast 6.3, allows Flex video servers to use RTP (Real-time Transport Protocol) streams as video sources enabling both the output of the RTP stream to air without an additional RTP decoder and the capture of the RTP stream to a file for later playback.
RTP is a licensed feature that must be enabled either at the time of initial purchase, or in the field by a Cablecast technician. To check if your system is licensed, open SXConfiguration in the system tray on your Flex server. The System tab will indicate if your server is licensed for RTP streaming. Please note that licensing is per server. If you own multiple flex servers each server you wish to play or capture RTP streams with must be licensed.
In order to play RTP streams out a flex server the stream must meet the requirements listed below.
|Encapsulation||MPEG2 Transport Stream|
|Video Codec||AVC (h.264)|
|Video Resolution||NTSC (720x480 @ 29.97), 720p (1280x720 @ 59.94), 1080i (1920x1080 @ 29.97)|
|Audio Codec||AAC, 2 channels, 48 Khz|
The list below contains RTP encoders that Tightrope Media Systems have tested and certified for use with Cablecast.

There are two workflows that need to be configured for RTP streaming.
To configure playback of RTP streams we will do the following steps:
To configure capturing of RTP streams we will do the following steps:
The flex server is now configured for Network Streaming. Read on to learn how to play Network Streams to air.
Your system is now set up to capture RTP streams.
RTP streams can be created and edited on the Network Streams Settings page. There is no limit to the number of RTP streams that can be defined. It is useful to create the RTP streams ahead of time so they can be recalled quickly when scheduling shows and record events.
To schedule an RTP stream we will create a new show which has the Network Stream format we created earlier. With the Network Stream format created we will be able to select from a list of pre-defined network streams, or create a new one. The rest of the show details and scheduling are just like any other type of show in Cablecast. Create the show, add it to the schedule, send Autopilot and you're good to go.
Capturing a network stream is the same as any recording in Cablecast. You have three options.
