Features
With the HDM500 High-Definition MPEG-2 Decoder, your 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 discreet 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
