IPVTL provides high density transcoding capability with lowest latency. Running on high performanced Intel Xeon processors with NVIDIA Quadro / Tesla video card acceleration, IPVTL is able to transcode up to 64 channels HDTV for internet audience on 1 single server. It has full support of common media encodings today, such as G.7xx, MP2/3, AMR, AAC, AC3, H.263(+), H.264(AVC), H.265(HEVC), MPEG-1, MPEG-2 and MPEG-4, also including the HTML5 video - VP8 VP9.

IPVTL accepts all kinds of media materials as transcoding input, including pre-recorded media files, TV tuner cards and network streams such as HTTP, MMS, RTSP, RTMP (flash video), RTP and MPEG-TS (DVB-S). It works well with familiar media streaming servers including Windows Media Service, RealNetworks® Helix Server, Adobe® Media Server, Wowza Streaming Engine, Nginx and other popular DVB-S devices in the market like Dreambox®.

IPVTL provides on-demand media file streaming as well. It can stream from any pre-recorded movie clips on your local disk, with transcoding on the fly. Any media file type with any codec is supported. What's more, you can schedule stream play list via streaming from folder (available on Windows currently).

For output, IPVTL supports the most popular streaming protocols today - Apple HLS and Flash RTMP pushing to Nginx-rtmp, Adobe Media Server, Wowza Streaming Engine or Red5 Media Server. MPEG-TS output in constant bit rate (CBR) is available for best compatibility with most IPTV STB and other devices.

IPVTL gives you full control of video and audio encoding profiles customized to your system requirements. Video resolution, quality, frame rate and bit rate, you can reshape your video stream fast and simple. IPVTL also provides professional video post process functions such as logo/delogo, watermarking and subtitle overlay.

For native RTP streams, the input and output media attributes can be easily imported or exported through SDP files (RFC 2327), which can then be fed to other collaborating applications in the whole scenario.
