Stradis
HDM500 High Definition MPEG-2 Video Decoder
Professional performance for world-class applications.
With a proven history of high quality output, versatility and
performance, Stradis has long been the standard-definition MPEG decoder
of choice for applications requiring true broadcast quality. Now the new
HDM500 High-Definition MPEG-2 Decoder delivers comparable performance in
applications requiring High-Definition.
Easy Integration.
The Stradis Application Programming interface (API) makes intergrating
the HDM500 into video systems fast and easy, and gives applications
complete control over all HDM500 functions. The API supports multiple
HDM500 decoders in a single computer with synchronized playback across
all cards.
Professional Performance. The Stradis HDM500
High-Definition MPEG-2 Decoder decodes MP@HL (4:2:0) video at up to 80
Mbps. It provides continuous, frame-accurate, seamless back-to-back
playback of all standard MPEG-2 streams. All popular ATSC-compliant
formats are supported: 1920x1080i, 1280x720p, 720x576p, 720x576i,
720x480p and 720x480i.
HDM500 applications include playback from disk for server applications
and real-time decoding from a satellite or terrestrial network.
Multiple Video Outputs. The HDM500 High-Definition
MPEG-2 Decoder has three video outputs for maximum flexibility. Use the
High-Definition Serial Digital Interface (SMPTE 292M) video output and
the Digital Visual Interface (DVI) or the analog RGB (or YPbPr) output.
It can also display the video image on the computer's VGA monitor (in
lower resolution to conserve PCI bus bandwidth).
Key Features
With the HDM500, your MPEG video application can offer:
- Continuous, seamless back-to-back
playback of multiple MPEG streams (which may be in different formats:
Transport, Program, System or Elementary streams) in all popular
ATSC-compliant formats including 1920x1080i, 1280x720p, 720x576p,
720x576i, 720x480p and 720x480i
- High-quality conversion of source
video to selected display format. Lock the output to one format and
all outputs will be in that format, regardless of the source format
- Frame-accurate, synchronized playback
across multiple decoders
- High-speed, random access and display
of any I-Frame in an MPEG file for variable speed reverse and
forward play, plus seamless switching to any I-frame of another
stream
- PCR-based clock recovery for 24/7/365
real-time stream reception for continuous decoding of streams
received from any common delivery mechanism, including satellite,
LAN, and ATM networks
- Complete control over all HDM500
functions via the API for Microsoft Windows NT, Windows 2000, and
Windows XP. Applications can access the API via a C interface or by
using the __stdcall calling convention
- API compatibility with all Stradis SDM
series standard-definition MPEG Decoders
Additional features for professional MPEG decoding and output:
- Still picture display from bit-map
files with transition effects and simultaneous audio playback for
"slide shows"
- True-color graphics over video or
still pictures with keying or indexed color with blending
- Digital control of video saturation,
brightness, contrast, and gamma
- Genlock (external framelock
synchronization) input
- Hardware Audio/Video synchronization
- High-Definition Serial Digital
Interface (SMPTE 292M) video output with 12 channels of embedded
audio
- 6 AES3 digital audio outputs, may be
used as 12 discrete audio channels or 4 may be used as IEC 61937/SMPTE
337M-2000 digital audio outputs to Dolby Digital® (AC-3) or MPEG
Multichannel® audio decoders
- One pair of unbalanced analog audio
outputs for monitoring
- Machine Control via remote connector
(9-Pin, RS-422A) can be configured as either "Controller"
or "Device"
- Linear Time Code (LTC) output based on
stream time codes or synthesized by the API
- Letterbox and pan-and-scan options for
displaying 16:9 images on a 4:3 display
- Support for extraction of EIA 608 /
EIA 708 closed captions with captions inserted into HD-SDI in
accordance with SMPTE 334M
- API provides three interface levels:
RateBuffer, Demux, and File
- DirectShow® filters for compressed
data input to the Stradis decoder
- SMPTE 302M-2002 support for
uncompressed digital audio in the Transport, Program, and System
streams
- Wave file playback and raw PCM audio
playback
- Audio "voice-over"
capability allows the application to replace the audio from the main
multiplexed stream with another audio stream
- Virtual streams based on a single,
repeated I-Frame that can be seamlessly played back-to-back with
other MPEG streams
- Decryption function for file-based
decryption using Stradis-supplied or user-definable algorithms
- Video capture interface for capturing
decoded video output in lower resolution and placing it into PC
memory
- Video image can be displayed on the
computer's VGA monitor in lower resolution to conserve PCI bus
bandwidth
