Perfect Streamer – guaranteed delivery of video streams anywhere in the world without using expensive networks
About the product
Perfect Streamer® is software for delivering digital streams of television channels via public Internet network anywhere in the world in Point-to-Point mode.
It uses proprietary protocol Perfect Stream that ensures reliable and stable video stream delivery without using expensive networks.
Also, standard transport protocols Pro-MPEG, SRT and RIST are supported. This allows to organize channels both via Perfect Streamer® and other software or hardware supporting the protocols:
- Perfect Stream transport protocol works on the principle of Automatic Repeat reQuest (ARQ). It has low resource consumption and allows to transmit high bitrate streams.
- Pro-MPEG COP3 is described in the IEEE standard. It is supported by a number of hardware manufacturers. Its important advantage is low latency. Its disadvantages are high network traffic and poor functioning in case of large packet loss (more than 0.3%).
- SRT is an open protocol designed by Haivision. Based on the UDT protocol. It has wide distribution and good packet loss performance.
- RIST - New open protocol. Based on the RTP/RTCP protocol. Works on the Automatic Repeat request (ARQ) setting without ACK, only NACK, which ensures high efficiency. Uses unicast and multicast.
Key features
- Linux operating system;
- IP SD/HD/UHD video streaming to 60 Mbit/s or higher for each stream;
- Supporting three different protocols for streaming via public networks. Loss may reach 40% and latency (RTT) may reach one second;
- UDP and RTP protocols are supported for local network;
- For supporting other transport protocols connection of external utilities (ffmpeg, gstreamer etc.) is available;
- MPEG-TS stream analysis, diagnosing problems;
- Stream synchronization and jitter elimination;
- Correction of PCR marks in the video stream (PCR Fix);
- Modification of MPEG-TS stream: filtration on the basis of PID, PID modification, change of the language metadata;
- Storage of diagnostics data in the local database;
- Displaying graphs;
- Encryption of streams using AES 128/256-bit algorithm;
- Visual display of content of streams («Mosaic»);
- XMLTV server. XMLTV import from external sources;
- Working with EPG. Data extraction from the stream and data aggregation in XMLTV format;
- MPEG-TS multiplexor;
- EIT generator for SPTS stream and multiplexor;
- Modifying broadcaster’s metadata in MPEG-TS (SDT etc.);
- Working with multiprogram MPEG-TS (MPTS);
- Working with DVB-cards (DVB-S, DVB-S2, DVB-T2, etc.), Receiving FTA channels;
- Stream transcoding directly in the streaming server to specified format and bitrate, using compatible hardware. Supporting all formats SD/HD/UHD and MPEG-2/H.264/H.265/AV1 (optional).
Advantages of using
- Stable functioning via the public Internet;
- Distribution of video streams from one server to any country of the world with minimum expenses on infrastructure;
- Easy maintenance by one dispatcher;
- Streaming in difficult conditions where packet loss is high (up to 40%), and Internet connection is poor (latency up to 1000 ms);
- Works on any standard hardware suitable for installing operating systems Linux CentOS, Ubuntu, Oracle Linux etc.;
- Low hardware requirements;
- High performance: over 20 Gbit/s of traffic from one server;
- Real-time monitoring of video stream delivery quality, on the client-side too;
- Statistics, graphs and reports on video stream delivery;
- Correction of broken PCR labels in video streams, especially important when receiving low-quality HLS video streams;
- Supporting standard transport protocols at the server output for delivery to destination hardware of the recipient: UDP Unicast, UDP Multicast, RTP, HTTP, HLS, SRT, RIST, Pro-MPEG etc.;
- Capturing TV signal from multiple streams into one with automatic switching function in case of disabling one of the sources;
- Encryption of streams using AES 128/256-bit algorithm to fulfill the requirements of right holders related to streaming security via public Internet network;
- User-friendly modern web interface for controlling the software product, adapted for controlling from the screen of any device, including a smartphone;
- Reception of FTA-channels from satellite or digital terrestrial television without the use of additional software, just DVB-cards installed on the server are enough;
- Quick setup and putting into operation, taking literally 10 minutes;
- Professional activation and security system;
- Integration with Zabbix and other monitoring systems (on order, there are ready-made scripts);
- On-the-fly TV stream transcoding function in the streaming or receiving server to specified format and bitrate. Supports solutions using compatible hardware from Intel and Nvidia (optional).
