Appendix E: Product Warranty Terms and Conditions ......42 Appendix F: FCC Notice ................43 QVidium provides the capability to inter-operate with most Content Delivery Networks (CDNs). As a result, the QVENC4K can send to a CDN in one of four common protocols, SRT, RIST, RTMP/RTMPS and HLS.

Using the Jitter Buffer in the QVidium decoder or ARQ software can often restore correct packet order and stream integrity, at the cost of additional delay. You can also avoid Dynamic Load Balancing by requesting MPLS (Multi-Protocol Labeled Switching) service from your ISP.

Page 15: Encoder Configuration
Each encoder profile allows you to output up to 4 copies of the encoded video into a unique IP stream, each to its own destination address and each stream copy individually configured with any of the available IP transport protocols that you select. ® Copyright 2023 QVidium Technologies, Inc.

UDP port or URL. Most protocols will require a destination IP address or DNS name for the receiver, but several of the protocols, such as QVidium ARQ, RIST, and SRT, allow you to leave the destination blank and have the receiver initiate the stream. We refer to this operation as Listener Mode or Pull Mode.
Page 17 NOTE: The QVENC4K will automatically upscale 1080i video input to 1080p. It cannot directly encode interlaced video, so a 1080i interlaced video input is automatically upscaled to 1080p progressive video before encoding. Figure 6.

Page 23 Note: For QVidium ARQ in Pull-Mode of operation, you must specify a different ARQ port than the UDP port. Under QVidium ARQ, you can both Push and Pull streams at the same time by entering an IP address/hostname to push streams while other receivers pull streams from your QVidium ARQ server.
Page 24: Qvidium Arq Video Transport & Error Correction
QVidium 2.3 QVidium ARQ Video Transport & Error Correction The QVidium QVENC4K Video Encoder™ features some of the most powerful and advanced error correction capabilities found in any video over IP product. The QVENC4K implements QVidium’s patented ARQ error correction and clock synchronization (US Patents #7,551,647 and #7,522,528) for robust video transmission with the lowest delay.
Page 25 For sending more than 4 output copies of a stream, either use an IP Transport that allows multicasting (and UDP, RTP, or RIST Simple Profile) or send the stream to a server or PC running the QVidium QVARQ-TxRep QoS Proxy server (see http://www.qvidium.com/proxy).
