Dual H.264 SDI/HDMI streaming encoder - DATAVIDEO DTV-2510-8218

Datavideo NVS-35 is a H.264 dual streaming encoder that allows you to live stream to two platforms at the same time (such as YouTube and Facebook), thus gaining more viewers, as well as recording in H.264 format. It is suitable for a variety of applications and can configure two different bitrates for recording and streaming at the same time. It has an SDI and HDMI video input and a balanced 2-channel XLR or stereo RCA audio input.Recording directly to SD card, supports multiple file systems (FAT32 / exFAT / NTFS) and continuous recording with no file size limit. About 50% of the viewers use their smartphone to watch the video stream and 94% of them prefer the portrait orientation. NVS-35 provides vertical screen streaming function and provides you to easily create a vertical oriented video with some basic settings. Audio output is selectable from optional embedded audio / external audio / mixed audio, with wide compatibility. NVS-35 handles SRT streaming protocol, no need to worry about unreliable network environment. Many broadcasters have experienced pixelated video when live streaming, often due to unstable network environments caused by bandwidth volatility. As we know, RTMP streaming over low bandwidth and unreliable networks can cause problems. With dvCloud, you can now replace the RTMP protocol with SRT, which will solve most of the streaming problems you may have. SRT is better than RTMP because it handles problematic networks more efficiently. Requires less bandwidth and resolves data errors faster. Datavideo's wide range of encoders, cameras and switchers are fully supported by SRT and dvCloud. Datavideo and dvCloud encoders deliver reliable streams over unreliable networks. By using a Datavideo encoder and dvCloud at the same time, you can use SRT (instead of RTMP) on the initial problematic connection, also known as the "First Mile". Once your video stream reaches dvCloud, you can rely on dvCloud's reliable high bandwidth network to deliver the stream to your favorite destinations, such as Facebook and YouTube.
