PCR/PTS/DTS - TEMI - SCTE-35 Graph
The service to be analyzed should not be encrypted. When a service is encrypted the PCR is not encrypted, but the PTS and DTS time stamps are part of the pay load and are encrypted.
This view uses the range selected in the filter. It does not use the PID-filtering of the filter. To toggle which time stamps / SCTE-35 markers are displayed in this graph use the check boxes on top of the window.
The last option for zooming is to point at area of interest, and scroll mouse wheel up. Zoom out by scrolling mouse wheel down.
When zoomed in you can pan to another part of the graph by holding the CTRL-button and moving the mouse.
For most components the PTS-marks will show a ascending line. The exception to this rule are the video-frames. Because of the structure of I,P and B frames a P frame has to be decoded before the preceding B-frames can be decoded. So the the P frame is broadcast out-of-order, before the preceding B-frames. The decoder then has to decode it first (indicated by the DTS time), before decoding the B-frames.After the B-frames are decoded and presented the P-frame is presented.
When the mouse pointer is over one of the temi markers in the graph a hover item will display the exact values of this descriptor.
This TEMI feature is still very experimental. Any suggestions for improvements are welcome. Also test streams are welcome. If you have any streams available, or suggestions/remarks please contact me to help improve DVB Inspector.
