PTS Graph

Display a graph showing the relationship between PTS values and PCR values for video and audio data.

Screen Items

Item	Description
PID	Display the PID of the packet with PTS that is being analyzed.
PCR	Display the PID of the PCR packet.
PTS-PCR	Display the average of the difference between the PCR value and the PTS value at the time of PTS reception.
Graph Area	PES data volume PTS-PCR difference Frame Timing Average value of PTS-PCR difference

Item	Description
1. PES data volume	Display the transition graph of the volume of PES data held in the program. `Blue area`：PES data volume graph `Red letter`： Maximum volume of PES data `Green letter`：Minimum volume of PES data
2. PTS-PCR difference	The horizontal axis indicates the time the frame was received. The vertical axis shows the difference between the PTS(DTS) and PCR values of the received frame. Frame type is indicated by a colored dot. `White line` : Differential value between PTS and PCR. Indicates the time from receiving the frame data until it is displayed. `Green line` : Difference value between DTS and PCR. Indicates the time from receiving the frame data until it is decoded.
3. Frame Timing	Display the relationship between the received time of the frame data and the displayed time in the figure below. `Upper axis` : Received time `Lower axis` : Presentation time
4. Average value of PTS-PCR difference	Displays the average of the difference values between the PTS and PCR values as a bar graph. Longer red bars mean longer time between frame reception and display.

Function	Description
V-axis adjust	Change the PTS-PCR display scale.
H-axis adjust	Change the time scale.
Format Select	Switch the frame type display.
