VPlay Multichannel Broadcast Server
VPlay is a next-generation professional software platform for television broadcast automation. It runs several SD/HD/UHD channels simultaneously on a single server with hardware GPU acceleration, built-in IP distribution, individual graphics for each channel, and hot 1+1 redundancy.
What Makes VPlay Competitive
| Criterion | VPlay |
|---|---|
| Channels per server | Up to 8 HD or 1 UHD 4K on a single machine |
| Architecture | Client-server; the server runs as a system service without a GUI |
| GPU encoding | NVIDIA, AMD, Intel Arc — hardware encoder for all IP outputs |
| IP outputs | UDP/MPEG-TS, HLS, RTMP, RTSP, MPEG-DASH, SRT, NDI — out of the box |
| Redundancy | Hot 1+1 with schedule synchronization between servers |
| Graphics | Built-in engine: up to 8 GFX layers, animations, PIP, crawl, RSS |
| Subtitles | SRT, STL, TBS → output as OP-42/47, EIA-608/708, DVB, TTML |
| Ad insertion | SCTE-35/104 and DTMF — detection and generation |
| DBMS | Not required |
Key Features
Multichannel Broadcasting with GPU Acceleration
VPlay uses the hardware capabilities of the graphics card to encode all output streams. A single server with an NVIDIA RTX 4060 or Quadro A2000 can run 2 HD channels simultaneously, each with several IP outputs, without quality loss and without overloading the CPU.
Supported GPUs: NVIDIA GeForce / Quadro / Tesla, Intel Arc. If no GPU is available, software rendering on the CPU is used.
Complete IP Streaming Stack
VPlay covers the entire IP distribution lifecycle without external encoders:
- UDP/MPEG-TS — broadcasting to DVB/IPTV networks
- HLS — multi-bitrate streams for OTT and CDN
- RTMP — direct streaming to YouTube and other RTMP platforms
- RTSP — for IPTV set-top boxes and monitoring systems
- MPEG-DASH — ABR delivery for modern web players
- SRT — secure transmission over unreliable networks (Caller/Listener)
- NDI — stream exchange within a local network without special hardware
- SDI — output to professional routers and monitors
Input Interfaces
| Type | Formats |
|---|---|
| SDI | SD / HD / UHD (Blackmagic, AJA, DekTec, StreamLabs MH4LM) |
| IP streams | UDP/MPEG-TS, RTSP, HLS, MPEG-DASH, SRT |
| NDI | NewTek NDI® |
| ST 2110 | SMPTE-2110 4K UHD |
| WEB | RTMP, webcams, URL sources |
| Analog | Composite, S-Video, YUV, Analog Audio |
| HDMI | 576 / 720 / 1080 / 2160 |
Graphics Engine
Each VPlay channel has an independent graphics processor that supports up to 8 simultaneous layers controlled in real time:
- Logos and static images (PNG, TGA, BMP with transparency)
- Crawl — text, RSS, dynamic data
- Roll — vertical scrolling credits
- Clock — analog and digital
- Timer — count-up and countdown
- PIP — live source over the broadcast
- Clip metadata — title of the current and next program
- Fill+Key — output to professional editing systems
Schedule and Playlist
Two on-air control modes that can be switched without stopping the broadcast:
- Playlist — looped playback of a content queue
- Schedule — broadcasting strictly by time of day with Fixed Time, Overrun, Underrun
Schedules can be imported from XML, CSV, and other formats. Content is loaded automatically from PAM storage.
Hot 1+1 Redundancy
Two servers work as a pair: Primary and Backup. In case of failure, switchover is automatic and frame-accurate. Schedules are synchronized in real time.
Regional Ad Insertion with SCTE-35/104
Detection of incoming cue messages and generation of outgoing ones in SCTE-35 (IP TS, HLS), SCTE-104 (SDI, NDI), and AWS SCTE-35 formats.
