    QVidium provides the capability to inter-operate with most Content Delivery Networks (CDNs). As a result, the QVDEC4K can send to a CDN in one of four common protocols, SRT, RIST, RTMP/RTMPS and HLS. These capabilities are described in Chapter 6. This feature allows the QVDEC4K to interoperate with large content gathering points such as Facebook and YouTube.

    QVidium 1.3 Reconfiguring and Resetting Network Settings In case you are not able to connect to the QVDEC4K™ through the network port(s) to a web browser, we have provided 2 alternate mechanisms for resetting the IP addresses and network settings: through CodecManager and through the USB console serial port. Any one of these 2 methods we describe in this section will allow you to recover in case the IP address was changed or set to DHCP and you do not know its current value.

    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.
  • Page 15 Audio Stream: Auto, 1, 2, 3, and 4. Default is Auto. When in Auto, the QVDEC4K will decode all of the Opus, AAC, or MPeg1/2 audio channels contained within the stream. Setting this to a value from 1 to 4 allows you to select only that audio stream for decoding to the embedded SDI output.

    2.2.3 Optional UDP Output The QVDec4K can also output a UDP stream copy of the input stream after processing to correct for packet loss. This can be a multicast stream and is often helpful for monitoring the video that the decoder is processing.

In the case of RTMP and HLS, the QVDEC4K converts the stream to TCP protocol. SRT uses a proprietary protocol called UDT that was originally designed for reliable file transfer.

    MPEG-2 transport stream.  ARQ uses QVidium’s patented error correction mechanism based on a time-constrained selective packet retransmission algorithm, in place of FEC. It also encapsulates the video as per COP3.2 (without the FEC) and RFC 2733. However it relies upon an upstream channel on UDP port 7020.
  • Page 29 ® QVDEC4K™ UHD/HEVC Video Decoder User Manual v.1 QVidium  UDP is similar to the RTP transport above, but does not add the RTP header to the UDP packets. Instead it simply encapsulates the MPEG-2 transport stream data directly into the UDP/IP packet payload.

    The video decoding bit rate limits specified below are subjective suggestions based on limited empirical testing. The QVDEC4K decoder will allow you to enter any video stream bit rate from 500Kbps to 80Mbps, and will attempt to produce the best video quality it can, based on the video bit rate you set.
