With Stradis SDM290(e)(x), 280(e)(x), 260(e)(x) and 230 standard definition decoders, 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)
•
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
•
Complete control over all decoder functions via the API for Microsoft Windows XP,
Windows 2000,. Applications can access the API via a C or C++ interface or by using the
__stdcall calling convention
•
API compatibility with all earlier-model Stradis SDM series MPEG Decoders
Additional features for MPEG decoding and output:
•
Decodes all MPEG-1 and MPEG-2 stream types and produces NTSC or PAL 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 and 64 levels of blending and
shading
•
Digital control of video saturation, brightness, contrast, gamma, and hue
•
Hardware Audio/Video synchronization
•
Two balanced analog audio outputs with line-levels up to 28 dBm
•
Vertical Interval Time Code (VITC) based on stream time codes or synthesized by the API
•
Closed captions (ATSC and proprietary formats supported)
•
Any VBI line can be overwritten with API generated data such as closed-captions or VITC
•
API has three interface levels (RateBuffer, Demux, and File Interface)
•
DirectShow® filters for compressed data input to the Stradis decoder and uncompressed
video output from the Stradis decoder
•
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 and placing it into PC memory
•
Video image can be displayed on the computer’s VGA monitor, with scan-rate and color
conversion
•
PC based YUV video frame buffer output capability which allows multi-zone applications
containing graphics generated by the PC and full motion video decoded by the decoder
