Page 13: Menu Commands
Menu Commands: File Open… Opens the "Open" dialog box. Also can open a Play List. See Play List, page 23. Close Closes the MPEG file that is currently open, but does not exit the application. Open Preferences Opens the "Open Preferences" dialog box. When the "Search For All Streams"...
Page 14 The Pids contained in the file (in the case of a Transport Stream) or the Stream IDs (in the case of a Program or System Stream) will be displayed in the "Select Stream" dialog box. The specific audio and video stream may be selected.
Page 15 Next File When using a Play List, stop playing the current file and immediately skip to the next file on the Play List. Only active when there is a "next file" available. Play [Ctrl-P] Same as the Play button. Begin playing the open MPEG file or the Play List. Loop Same as the Loop button.
Page 16 Keep Aspect Ratio Checking this keeps the computer’s display in 4:3 height to width aspect ratio when manually resizing the window. When unchecked the window can be manually sized into non-standard aspect ratios. Window Size Full Screen [Ctrl-F Scales the video to display full screen on the computer display. Does not affect the video output.
Page 17 View SMPTE Code Displays SMPTE Time Code. A time-code is encoded in each I-frame, typically at the beginning of each GOP. During playback, the time code is extracted from each I-frame. The time code is interpolated between I-frames. View STC Displays the System Time Clock.
Page 18 16:9 When 16:9 is selected, no action is taken regardless of the stream type. Volume Control… Opens the "Volume Control" dialog box. Controls the decoded audio output only. Does not affect CD-ROM "pass-through" audio. The volume and balance settings are written into the Windows registry and are remembered from session to session.
Page 19 Offset Time Code Displays the System Time Clock. GenLock Checking this locks the output video sync to the incoming video sync. Sync Mode (Active only when no file is open.) System Clock Uses the Presentation Time Stamps to synchronize video and audio. The audio decoder compares the audio PTS, when encountered, with the STC, and corrects the audio if the difference between the two is more than five milliseconds.
Page 20 On-Screen Display… Opens the "OSD Properties" dialog box, used to superimpose a Windows bit- map over video. Entering the X & Y coordinates of the upper left corner controls the position of the graphic on the screen. Note that undesirable results may occur if the X &...
Page 21 The stored image can be either a standard Windows® BMP 24 bit RGB color image or a Stradis proprietary YUV format that is 720 x 480 pixels (when NTSC is selected) or 720 x 576 pixels (when PAL is selected).
Page 22: Multiple Decoders In A Single Computer
Display the software revision number and copyright information. Multiple Decoders in a Single Computer To use multiple Stradis MPEG-2 Decoders simultaneously in one computer, multiple instances of the decoder application (Smpegdec.exe) must be run. This can be done by adding the program argument -X where X is the decoder board number (1 through N).
