HDM500e High Definition Decoder Features
Key Features for MPEG Video Applications
- Continuous, seamless back-to-back playback
of multiple MPEG streams (which may be in different formats: Transport,
Program, System or Elementary streams) upconverted or downconverted as
necessary to 720p or 1080i.
- 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 decoder functions
via the Stradis Application Program Interface (API) for Windows.
Applications access the API with a C-style interface 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
- Support for extraction of EIA 608 / EIA 708
closed captions with captions inserted into HD-SDI in accordance with SMPTE
334M
- SMPTE 302M-2002 support for uncompressed
digital audio in the Transport, Program, and System streams
- Wave file playback and raw PCM audio
playback
- Virtual streams based on a single, repeated
I-Frame that can be seamlessly played back-to-back with other MPEG streams
- Video image can be displayed on the
computer's VGA monitor in lower resolution to conserve PCI bus bandwidth
Stradis HDM500ex Decoder Operation Highlights
