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
live streaming audio/video content, while simultaneously playing out live
networked streaming video.
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, MPEG-
2, 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.
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).
