5. When sending a video stream over a LAN or other private hardwired network, we recommend
selecting UDP. You can also select QVidium ARQ, SRT, RIST, RTSP, or HTTP (HLS) to
receive from a third-party encoder over the Internet.
6. Click on

button to save your changes. None of your changes will
be saved nor have any effect unless you first save them. These changes are stored in
permanent memory and will persist even after a power failure.

select the desired profile, to then click
Start
to start receiving the stream.
If you have connected an SDI video display to one of the SDI outputs (BNC or SFP) you should
now see your video.
NOTE: The QVDEC4K is only designed to accommodate HD-SDI, 3G-SDI, 6G-SDI, and 12G-SDI
SDI interfaces for video resolutions from 720p through 2160p. The QVDEC4K cannot output
standard definition (480i/576i) video output. However, you can upscale (or downscale) the IP input
stream to higher (or lower) video output resolutions and frame rates from the
Video Output
setting
in the profile.
2.2 Detailed Decoder Configuration
As shown in Figure 2, the decoder profile configuration page lets you set the video output
resolution and frame rate and audio channel processing. The QVDEC4K decoder will automatically
detect and decode the video and audio formats from the input IP stream. The decoder contains a
built-in video scalar that provides the QVDEC4K the ability to change the video resolution before it
is decoded and output as a stream. The QVDEC4K can pass-through AC3 and multichannel audio,
or downmix it to stereo. It also automatically detects and passes through CEA-708 Closed
Captions, SCTE-35 to SCTE-104, and HDR Metadata.
