Creating a live channel
When creating a new live channel you will be presented with the screen shown below.
You have the following options:
Channel Name
Here you must choose a name for your live channel. The channel name can contain uppercase and
lowercase characters but no white space.
Channel Description
Here you can add a brief description of the channels content, this is used by the NVD-30/35 set top
boxes.
Player Page title
Here you can change the text that is displayed at the top of the web player’s page for this channel
only.
HLS streaming
Here you can enable or disable HLS streaming, if HLS is disabled the inbuilt web player is also
disabled.
HLS streaming
Here you can select Live or Event, Live mode should be used in most cases. In Live mode the player
will play from the end of the HLS playlist (live position) in Event mode the player will always start
from the beginning of the Playlist (the start of streaming). When using Event mode you must ensure
the HLS playlist length (On the settings page) is set to a value greater than the planned event time.
Please Note: Event mode is currently only supported by the NVD-3X in STB mode.
Inputs
Once you have created a live channel you will be given a RTMP URL that will allow any encoder to
push live video to the channel. You can also feed your channel by pulling in an existing stream or
using an input card from Black magic design.
Pull URL
Here you can pull any existing IP stream into the channel, RTMP, UDP, RTSP and HTTP streams are
supported. You can setup multiple source streams and select the one you want to use using the
enable/disable buttons on the far right. To stop pulling in any streams select ‘Select No Pull URL’.
By default, the audio and video will be set to ‘passthrough’ in this mode no transcoding is
performed, alternatively you can choose to transcode the source audio and or video. Please note
that if the source is MPEG2 you must transcode the video and audio.
For details of transcoding options please see the transcoding and encoding options section of this
guide.
Decklink Source
Here you can use an input card from Blackmagic Design to feed the channel directly from HDMI or
SDI sources. We currently support all Blackmagic Decklink, mini monitor and mini recorder cards
using the Desktop video 10.8.4 driver version.
As Blackmagic cards feed the system with uncompressed video you must set the H264 video and
AAC audio encoding options as required.
You can setup multiple sources if your card has more than one input or you are using multiple cards.
Select the source you want to use using the enable/disable buttons on the far right. To stop pulling
in any source select ‘Select No Pull URL’.
Datavideo Source
Here you can use an input card from Datavideo to feed the channel directly from HDMI or SDI
sources. The Datavideo cards use hardware video compression and software audio compression.
Please note that Bitrate is used when in CBR mode and Quality is used when in VBR mode. 1000 is
the lowest quality settings and 10000 is the highest.
You can setup multiple sources if your card has more than one input or you are using multiple cards.
Select the source you want to use using the enable/disable buttons on the far right. To stop pulling
in any source select ‘Select No Pull URL’.
Outputs
Push URL`s
Push URL`s are optional. Here you can push the incoming stream on to one or more destinations
simultaneously. We can push to destinations using RTMP or MPEG-TS protocols.
RTMP
Using RTMP you can push a single stream out to various streaming platforms such as YouTube,
Facebook, Wowza etc.
Simply enter the RTMP URLs you would like the stream to be pushed to. By default, the audio and
video will be set to ‘passthrough’ in this mode no transcoding is performed, alternatively you can
choose to transcode the source audio and or video.
MPEG-TS
Here you can send out a unicast or multicast MPEG-TS stream, examples below.
Unicast
Multicast
Decklink Output
Here you can use an output card from Blackmagic Design to decode the channel to HDMI or SDI. We
currently support all Blackmagic Decklink, mini monitor and mini recorder cards using the Desktop
video 10.8.4 driver version.
You can setup multiple outputs if your card has more than one output or you are using multiple
cards.
Access Control
Here you can restrict what IP addresses can publish or playback using RTMP. In whitelist mode, only
the listed IPs can publish or playback, in blacklist mode all but the listed IPs can publish or playback.
You must enter the IP address followed by its abbreviated subnet mask, for example 255.255.255.0
is a 24-bit mask so is represented as /24. Please consult your IT department if unsure about these
settings.
Recording
Here we can enable recording, you have three options:
Always –Audio & Video
The software will record as soon as an input stream is detected and will stop recording when the
stream is stopped. Audio and video are recorded together.
Always –Audio Only
The software will record as soon as an input stream is detected and will stop recording when the
stream is stopped. Only audio is recorded.
Manually start/stop –Audio & Video
Recording will not happen automatically, the user must start and stop recording manually. When
enabled button to start and stop recording will be displayed next to the channel name. Audio and
video are recorded together.
Recorded files Suffix
By default, the recorded file is name after the channel name, this option allows you to add additional
text into the file name.
Give each recording a unique time stamp
When checked a unique time stamp will be inserted into the file name of each recording. When this
option is not checked the recorded file name will always be the same, this means subsequent
recording will overwrite the previous file.
Append to recorded file
This option should only be used when ‘Give each recording a unique time stamp’ is not checked.
When checked subsequent recording will be joined to the previous file creating one long recording.
Max. Recorded file size
Here we can limit the recorded file length by size, when this limit is reached a new file will be
created. No limit is set by default.
Max. Recorded file interval
Here we can limit the recorded file length by time, when this limit is reached a new file will be
created. No limit is set by default.
Auto publish recorded file when done
When enabled a recording will be published as soon as recording is stopped.
Include in group record
Any channel with this checked will start and stop recording together, this can only be used in manual
recording mode.
Redirect to VOD if offline
When enabled the DVS-200 web player will redirect to the last published VOD content if the live
stream is offline.
Delete recordings older than
Automatically delete recordings older than a certain age. This option will delete the source
recordings; it will not delete the published files.
Managing recordings
Recordings are listed at the top of the channel settings page, a maximum of 10 files are listed per
page.
You have the following options:
Publish
Will publish the selected files, this makes them available to playback and embed (Converts the
original file to HLS).
Delete
Will delete the selected files but won’t delete the published (HLS) files.
