1.1 Overview
QVidium’s collection of broadcast video network products includes the QVENC HD H.264 video
encoder and its corresponding QVDEC decoder. These products are derived from
QVidium’s
original
QVPRO HD Video Codec™ (currently available only by special order). The QVENC and
QVDEC use the same video processor and same firmware as the QVPRO H.264 HD Video
Codec™. The QVPRO can encode, decode, or transcode standard or high definition video using
either MPEG2 (main profile) or MPEG4-AVC (Part 10, H.264 High Profile, Level 4.1) compression,
and to interface a video feed from a wide range of video standards and connections for transport
over nearly any IP network.
The QVENC includes the encoding and transcoding capabilities of the QVPRO. However while the
QVPRO has SDI and HDMI inputs, the QVENC keeps the SDI/HD-SDI/3G-SDI interface, but
replaces the HDMI input with Composite and S-Video inputs. It also adds two pairs or analog audio
inputs and an S/PDIF input for AC3 Dolby Digital audio. The QVDEC implements the decoding
functionality of the QVPRO. However, in addition to the SDI/HD-SDI/3G-SDI and HDMI outputs, it
also adds a Composite video output, 2 pairs of stereo analog audio outputs, and an S/PDIF output
for AC3 audio.
All of these QVidium video networking products include
QVidium’s patented, advanced ARQ Error
Correction and clock synchronization. In addition, they also include the option of using industry
standard ProMPEG FEC, or SMPTE-2022, for compatibility with third-party products. With these
advanced Quality of Service (QoS) features, the H.264 HD Video
Codec™ can send video over
nearly any network and across the world, including wireless connections and the public Internet,
with unsurpassed video transport quality and state-of-the-art video compression for minimizing
bandwidth.
