The F239+ AVerCaster HD Duet Plus Dual Channel Video Encoder from AVerMedia allows broadcasting and recording of two independent Full HD video streams at the same time. It can take one or two HDMI or component video sources (up to 1920 x 1080 Full HD resolutions) and can encode two independent video streams of similar or varying bit rates for broadcasting or recording. The encoder offers multicasting which allows live video from the F239+ to be broadcast to an unlimited number of viewers.

The dual H.264 High Profile codecs and Gigabit Ethernet ports enable the encoder to simultaneously live broadcast two independent HD video streams in Duet mode, allowing for multiple angles of live streaming. A single F239+ encoder can provide single or dual video streaming services to an unlimited number of viewers over an Intranet or Internet with minimal network bandwidth usage.

In Recording mode, one encoder can be used for streaming videos, while the other simultaneously records the same input source for high quality backup or VoD playback. With two independent codecs, bit rates can be adjusted separately for each output to account for network bandwidth or high quality VoD content. Splitter mode allows a single stream to be broadcast at different bit rates, or supports different protocols and service providers.

The F239+ Encoder features dual HDMI and component inputs, enabling it to easily receive video signals from compatible Content Delivery Network (CDN) services such as Facebook Live, Wowza, CDNvideo, YouTube, Twitch, Ustream, and more. In addition, the encoder is compatible with a wide range of client devices such as desktop computers (using VLC or mPlayer), camcorders, IP/TV set-top boxes, digital whiteboards, and digital signage.
