The Mividi Multiviewer can monitor a number of different types of input streams in a single system, including
- ST2110 video and audio stream
- Transport streams over UDP or RTP/UDP multicast
- HLS and MPEG-DASH
- Uncompressed video over SDI
- NDI streams
A single system can support up to ~10 1080 HD or ~20 SD ST2110 streams. For encoded video stream, a single system can support ~30 1080 HD or ~60 SD H.264 encoded video streams.
Product Description
Mividi Media Systems Inc provides several multiviewer products for monitoring a number of different types of video input streams, including TS over UDP, RTP, HLS, MPEG-DASH, SDI, NDI. The Mividi Multiviewers now also provide full support to the SMPTE 2110 uncompressed video streams on the same system.
The SMPTE 2110 group of standards define the transport of compressed and uncompressed video, audio and metadata in the IP network. These standards enable using a single unified IP network to deliver all types of media data including compressed and uncompressed video streams. But there are also challenges of using IP network to transport uncompressed video because the high bandwidth of uncompressed video streams. At minimum 10G networks are required and networks that can support even higher bandwidth are designed, such as 25G or even 100G. To support the high bandwidth input streams, it uses a specially designed PCIe board that can perform packet processing on board to conserve host computer’s memory bandwidth and CPU cycles to save resources.
The Mividi multiviewers can show the video and audio volume bars of multiple input streams of different formats on the same monitor screen. It will also monitor the input streams for possible errors, including loss of the stream, black and frozen frames, audio loudness errors including silence errors. It normally offered as a 1U rack server with Windows 11 Pro OS, but other hardware configuration is also available.
Flexible Multiview Display
The Mividi Multiviewer solution offers flexibility of Multiview display. It can display any number of video programs if the hardware resource can support it. The location and size of each display panel can be arbitrarily configured.
The ST2110 video streams are uncompressed and therefore have very high bitrate. For example, the bitrate of a 1920 x 1080 HD video stream is typically between 1-2 Gbps depending on video frame rate and pixel format. In order to receive multiple of the high bandwidth streams, the Multiviewer uses a specially designed network receiver board. Two options are available: one with 10G and the other with 25G interface.
Local and Remote View of Output
Users can connect the outputs of a graphic card to local TV monitors for multi-viewer display. Our recommended graphic cards are Nvidia Quadro or RTX series, although other type of cards can be used. The Nvidia cards normally contain 3-4 DP (Display Port) output which can be easily converted to HDMI if your TV monitors do not take DP inputs. One to four TV screens may be connected to a single server.
In addition to local display, the multiviewer can also capture the display screen and generate an IP stream for remote view of the multi-viewer output. Multiple streams may be generated for multiple display screens. Different streaming formats are supported based on the need of remote users, including UDP, RTP and TS over HTTP, HLS and SRT.
Error Detection and Alarms
In addition to displaying video and audio volume bars, the system will also monitor a number of error conditions in the input streams, including:
- Loss of audio or video input streams;
- Black and frozen frames;
- Loss of audio sound or loudness level is not within user specified range.
Users can specify the test thresholds depending on input video streams. Multiple configuration profiles can be created for different type of video programs. For example, one test profile can be created for all news channels and other profile can be created for movie channels.
The system provides visual, email and messaging alarms when errors are detected in input streams. The alarm methods are configurable by selecting specific alarm triggers, time periods and email and message frequency.
