Internet Streaming to Local Broadcast Gateway – ILG200

Use Case 1: Convert Internet OTT Streams to UDP Streams

The Mividi Internet Streaming to Local Broadcast Gateway (ILG200) converts input IP streams using the HLS, RTMP, RTSP, and SRT protocols to MPEG-2 TS over UDP streams. The Gateway receives input streams via IP NIC, re-multiplexes video and audio data packets and creates a multiplexed TS and then outputs the TS in the form of UDP steams. The output UDP stream is single-program variable bit rate (VBR) or constant bit rate (CBR) TS.

The Gateway can also be used as a demultiplexer which can convert a single multiple program TS (MPTS) to multiple single program streams (SPTS). In addition, it can playout recorded transport stream files in UDP streams.

Output UDP channels can be created using multicast or unicast IP addresses. A single UDP output stream can be generated from multiple input source streams that are played out according to a preconfigured time schedule. Both live input streams and VOD streams can be used as input source for UDP stream output. The playout time can be scheduled in advance with repeat options.

The software can generate up to 25 HD or 40 SD simultaneous output UDP streams in a single system with recommended CPU, memory and NIC configuration.

Use Case 2: Transport Live Video over the Internet using SRT

Secure Reliable Transport (SRT) is a UDP based media transport protocol with low-latency and ability of re-transmission of lost packets. The Mividi Gateway provides a solution for transporting media using SRT. In a typical configuration, two Gateway systems can be used as two end-points. One is used as a transmitter which converts various input streams such as UDP streams to SRT streams, and the other one is used as a receiver which receives the SRT streams and convert them back to UDP streams. If a stream processor on the remote site can receive SRT streams directly, it can also be used as an end-point. In addition to UDP streams, other type of input streams including RTP, RTMP, RTSP can also be converted to SRT streams for media transport.

Cloud-ready Software Solution

The Mividi ILG200 is a software program that runs on standard Windows platforms, including Windows 10, 11 or Windows Server 2012, 2016, 2019 or 2022 OS. The main application is a Windows service program that can run 24x7 unattended once the input sources and output channels are fully configured. The software is very easy to use and maintain.

The software is fully cloud-ready. It runs on standard public cloud such as Microsoft Azure and Amazon AWS services. It does not require any special hardware beyond those offered by the standard servers in cloud services.

The ILG200 software is based on the client/server software architecture. The main stream processing functions are contained in the server module. The client application provides a user interface for viewing the status of input and output streams, and configuring the server application. The client application can also run on remote computers in the same LAN for remote access to the server module. Multiple client applications can access the same server at the same time by different users. In addition, a single client application can also be used to link multiple ILG200 servers in different locations and manage these systems from a single access point.

To input and output streams, the standard network adapters can be used. 1G or 10G NICs are supported.

Automatic Error Detection and Alarms

The ILG200 system will continuously monitor the input and output streams for stream errors, including:

• The loss of input or output streams
• The loss of audio or video component
• Frozen or black video frames

By monitoring its own output streams, system or software failure can be detected.

The system provides multiple ways of sending error alarms, including email, SMS, Slack channels, audio sound and SNMP traps. The alarm triggers can be configured for each error type. A full SNMP MIB is also provided for polling error status.

All errors and alarms are logged in the database and can be reviewed at a later time. Error and alarm records can be searched and exported in text format. Reports can be generated to summarize the error trend over a period of time.
