Video Management and Distribution
Vision2
Vision2 consists of number services which correspond to the main video functions:
Archive: The Vision2 Archive service provides a multi-format, multi-bitrate storage system for
video or audio files. Video in the archive can be accessed on demand by PC users, from tablets,
or set-top boxes. Users can attach metadata to each video containing information about the
video contents; this metadata can be customized by the system administrator. The Vision2
search feature can then be used to search videos by the contents of the metadata.
DVB: The Vision2 DVB Service provides and manages a single Digital Video Broadcast (DVB)
multiplex of live TV channels to the system. Terrestrial, satellite, and cable TV providers now use
digital rather than analog transmission systems to deliver their content.
Record: The Vision2 Record Service provides the ability to record a Transport Streamed MPEG
Live Channel into an Archive. You can either record continuously creating files of a fixed
duration, or you can manually record a specific event. Alternatively you can schedule recordings
to happen at particular times and dates.
Producer: The Vision2 Producer Services allows you to create a scheduled TV channel. You can
schedule the Producer to display either MPEG 2/ MPEG 2 - h264 Live Channels or MPEG-2 or
MP4 H.264 files from a Vision2 archive.
Reflector: The Vision2 Reflector Service is used for the following tasks:
To unicast a local MPEG 2/ MPEG 2 h264 vision2 channel over the internet (multicast
streams cannot travel over the internet) so that remote users can view this channel, this
could be to a remote vision2 installation.
To receive a unicast MPEG 2/ MPEG 2 h264 vision2 stream from a remote Vision2
installation and broadcast this as a local live channel.
To add an external source e.g. unicast MPEG 2/ MPEG 2 h264 stream from the
internet/local network as a local live channel. Like unmanaged channel but for unicast
rather than multicast
To make a copy of a local MPEG 2/ MPEG 2 h264 vision2 channel and broadcast it from
a second network interface card. This is less common
Encoder: NMX-ENC H.264 Encoders connect directly to sources including PCs, cameras and set
top boxes and provide the on-ramp to stream the video on a network using a network media
solution like Vision2. These robust encoders offer standardized, bandwidth-efficient encoding
for SD and HD sources.
