Comprehensive TS Analysis
The TSM Probe provides comprehensive TS analysis for MPEG transport streams. It supports MPEG-2, H.264/AVC, and H.265/HEVC video encoding formats, as well as commonly used audio formats including MP3, AAC, AAC plus, and AC3. It can also decode DVB SI and ATSC PSIP metadata tables and perform standard compliance checks on these data.
The system performs detailed TS error checks based on DVB test guideline TR 101 290 and reports all three priority level errors. It analyzes transport stream program structure, measures PID bitrate, performs PCR, and buffer analysis, detects any black and frozen frames, and monitors missing audio and video element streams.
In addition to MPEG transport layer testing, the system also performs IP and HTTP layer testing, including MDI measurement on IP streams. It measures video segment downloading parameters and monitors delay on HLS input streams, as well as HLS playlist syntax analysis.
All errors and alarms are logged in the database and can be reviewed at a later time. Reports can be generated to summarize TS status over a period of time.
Error Logs and Alarms
The system provides multiple ways of sending error alarms, including email, visual displays on a multiviewer screen, and audio sound. The alarms can be triggered by errors selected by users, such as loss of input, audio or video components, black or frozen frames, etc.
