It features 8/16/24 HD channels input with MPEG-4 AVC/H.264 video encoding and LC-AAC or HE-AAC audio encoding; making it suitable for a wide range of applications. The device can receive signals from a variety of sources; including STB; PC; TV; and more; and can transfer live programs over the internet/LAN. It can output IP signals over UDP (Unicast/Multicast); SRT; RTSP; RTMP; HTTP; and HLS; allowing users to receive the signals on their PC; phone; and other mobile terminals. With the DTV-4339S-B; users can access their IP STB; PC; or TV from anywhere to watch their programs. Also suitable Cable digital TV adjacent frequency front-end system; hotel IPTV network TV system and hotel satellite digital TV system.&nbsp; <img style="margin-left:auto;margin-right:auto;" data-srcid="-" src="https://image.doba.com/dgd1-JYDLydzLBFVr/fmuser-dtv-4339s-b4347s-b4355s-b-81624-hdmi-mpeg4h264-in-81624-spts-osd-encoder.jpg" alt="dropship FMUSER DTV-4339S-B/4347S-B/4355S-B 8/16/24 HDMI Mpeg4/H.264 in 8/16/24 SPTS OSD Encoder" /> &nbsp;<h2>Features:</h2>FMUSER DTV-4339S/4347S/4355S-B&nbsp;supports MPEG4 AVC/H.264 video encoding format; which ensures high video quality even at lower bitrates; making it suitable for a wide range of applications.FMUSER DTV-4339S/4347S/4355S-B&nbsp;also supports MPEG1 Layer II; LC-AAC; and HE-AAC audio encoding formats; as well as AC3 Pass Through and audio gain adjustment; allowing users to fine-tune the audio output to their specific requirements.FMUSER DTV-4339S/4347S/4355S-B&nbsp;supports IP output over UDP and RTP/RTSP protocol; which enables easy integration with existing digital distribution systems.FMUSER DTV-4339S/4347S/4355S-B supports QR code; LOGO; and caption insertion in multiple languages; making it suitable for use in a wide range of applications around the world.New update feature: IP output over UDP; RTP; RTSP; RTMP; HTTP; HLS; and SRT protocols (Only support STPS; NO MPTS); making it compatible with a wide range of digital distribution systems.New update feature:&nbsp;DTV-4339S-B/4347S/4355S-B&nbsp;supports OSD (On-Screen Display) functionality; allowing users to insert images; QR codes; text; and other visual elements into each encoded video stream. This feature provides users with greater flexibility and control over their digital content; enabling them to customize their programs and better engage with their audience.The device features a &quot;Null PKT Filter&quot; function; which ensures that only valid data is transmitted; reducing network traffic and improving overall system performance.Null PKT Filter is a data filtering function that can filter out invalid data packets in transmission. In digital distribution systems; the reliability and efficiency of data transmission is very important. If invalid packets are transmitted; they can consume network bandwidth and affect overall system performance. Use the Null PKT Filter function to filter out these invalid data packets; reduce network traffic; and improve system transmission efficiency and performance. Therefore; the Null PKT Filter function of the FMUSER DTV-4339S-B multi-channel encoder can ensure data reliability and system efficiency.FMUSER DTV-4339S/4347S/4355S-B&nbsp;can be controlled via web management; with easy updates via web; allowing users to configure the device to meet their specific requirements quickly and easily.Chart of Per Module Principle:&nbsp;&nbsp;<img data-srcid="-" src="https://image.doba.com/dgd1-ouVDhdiFAQqp/fmuser-dtv-4339s-b4347s-b4355s-b-81624-hdmi-mpeg4h264-in-81624-spts-osd-encoder.jpg" alt="dropship FMUSER DTV-4339S-B/4347S-B/4355S-B 8/16/24 HDMI Mpeg4/H.264 in 8/16/24 SPTS OSD Encoder" /><h2>Chart of Per Module Principle:</h2>&nbsp;
