1.1 Overview
QVidium’s QVDEC4K™ streaming video decoder is a high performance, high resolution video over
IP networking device capable of decoding broadcast quality video at resolutions up to 3840x2160
and at frame rates up to 60 frames per second. Utilizing a high-end, state-of-the-art multi-core
CPU with a specialized on-chip hardware video decoding core, the QVDEC4K can process video
in real-time using HEVC/H.265, MPEG4-AVC/H.264, or MPEG-2 compression. The QVDEC4K can
receive 4:2:0, 10-bit, UHD/4K video. Along with the video, the QVDEC4K can process up to 8
channels of audio (4 stereo pairs) with a selection of common audio decoding formats, including
surround sound 7.1 and AC3.
QVidium was the first company to invent a negative-acknowledgement feedback-based video
transport and error correction mechanism, called QVidium ARQ (Automatic Retransmission
request), for which it holds 2 U.S. patents and an Emmy© Award. QVidium ARQ enables the
transport of broadcast quality video over nearly any Internet and wireless network, provided that it
has sufficient bandwidth to carry the stream.
Like all other QVidium video encoder, decoder, gateway and server products, the QVDEC4K
employs QVidium’s patented ARQ. In addition, the QVDEC4K also offers other video transport and
error correction with protocols such as Zixi, SRT, RIST for live video error correction and transport,
and RTMP/RTMPS,and HLS for compatibility with Content Delivery Networks (CDNs) such as
Facebook, YouTube, and Ustream.
The following sections and chapters explain how to configure and operate the QVDEC4K using
screen snapshots with explanations of the various settings, and provide examples of the output
you should expect.
