1 Overview
Application Overview
he QVidiumHD™ Video StreamViewer is a high-definition networked-video
software application that can locally store HDV, DVC-ProHD, and other formats of
T
The QVidiumHD StreamViewer records, decodes, and plays out live networked MPEG-2,
MPEG-4 SP/ASP (MPEG-4 part 2), or MPEG-4 AVC (H.264, or MPEG-4 part 10) encoded
video streams embedded within an MPEG-2 compliant Transport Steam and transported
over an IP network, encapsulated either in RTP or raw UDP/IP packets. This includes
DVB-compliant CBR (constant bit rate) video streams, ProMPEG, and HDV video streams.
It can also handle DV and DVCPro-HD encoded video streams sent by a Qvidium
IEEE1394 IP Gateway. The QVidiumHD StreamViewer can also handle MPEG-1, MPEG2, and Dolby AC3 encoded audio. The RecordManager can simultaneously record the
incoming stream, while playing the recovered digital audio and video signals. It can display
the live video stream directly onto a high-resolution monitor or display device in full-screen
mode, or within a separate video play-out window when used as a viewfinder or monitor for
the recording function. The RecordManager automatically detects the video resolution for
both High-Definition and Standard Definition video streams and resizes the video image
accordingly. It also automatically decodes and displays any closed captioning data
embedded within the video content.
live streaming audio/video content, while simultaneously playing out live
networked streaming video.
The QVidiumHD™ Player is supplied as a software application designed to run under the
Microsoft Windows™ Vista, XP, or Windows™ 2000 operating systems. The QVidiumHD
StreamViewer employs QVidium’s implementation of the ProMPEG standard for Video
over IP with Forward Error Correction as well as Qvidium’s patent-pending ARQ error
correction mechanisms, while also taking advantage of Microsoft DirectX™ and Microsoft
DirectShow™, to provide exceptional video quality and the most robust and error-free
stream reception and play-out possible, even in the face of network impairments, such as
lost packets, jitter, and packet reordering. QVidium’s implementation of video encoding
and ProMPEG video standards allow the QVidiumHD™ player to be fully compatible with
any video signal source that also adheres to the ProMPEG standard for Video over IP (Code
of Practice #3, Release2, Annex A).

2.1
The QVidiumHD™ StreamViewer is a software application that combines a streaming
Video over IP hard disk recorder with a high-definition video decoder to provide a versatile
and robust means for receiving, recording and displaying live video content from a wide
variety of video sources.
The QVidiumHD™ StreamViewer is built around common industry standards for video
over IP streaming to insure compatibility, flexibility, and interoperability with other video
over IP encoders and camcorders. These standards include: MPEG-2, MPEG-4, DV, and
DVCPro-HD video decoding, Dolby AC3, MPEG-1 Layer-II, and MPEG-2 audio decoding,
MPEG-2 Transport Streams, ProMPEG Video Transport and Forward Error Correction
(FEC), RTP/UDP/IP video packet protocol, and Microsoft DirectX™ and DirectShow™
video and audio technology. (Windows Media video decoding is available as an additional
option upon request.)
This instruction manual provides detailed operation instructions for each of the
StreamViewer’s two main functions:
Operation
Principles of Operation
• LIVE STREAMING VIDEO RECORDER
• LIVE STREAMING RECORDING MONITOR AND VIDEO STREAM PLAYER
2.2
The Stream Player recognizes, decodes, and displays NTSC closed captioning, as specified
by the Advanced Television Systems Committee standard ATSC A/53 for Video Blanking
Interval (VBI) data embedded on video line 21. (At present, European Teletext for Pal
video is not supported.) When live streaming video content contains closed captioning data
(locally stored video with closed caption is not supported) the Stream Player will
automatically display the closed captioning text as an overlay on the displayed video. This
display of closed captioning text is independent of the audio and will not affect play out of
the audio feed.
