User manual TEKTRONIX MTS400 BUFFER ANALYSER DATASHEET

[. . . ] MTS400 Series MPEG Analysis Tools Buffer Analyzer Data Sheet Characteristics Applications When developing professional and consumer equipment, particularly encoders and set-top boxes, the characteristics of the test streams being either generated or used as stimulus need to be ascertained. [. . . ] The Buffer Analyzer verifies conformance of a stream to the T-STD model. Verification of the H. 264/AVC HRD method is covered by the MTS4EA product. Feature Details Features & Benefits T-STD Buffer Analysis of Selected Elementary Streams within a Transport Stream File Graphical Displays of TB, MB, and EB Occupancies Supports a Wide Range of Audio and Video CODECs Types, Including AVC/H. 264 and MPEG-4 AAC Message Log Reporting of Standards Compliance Violations Trace View Provides Details of the Buffer Movements for In-depth Analysis of the Results Synchronize Selected Log Entry with Trace and Buffer Occupancy Graphs Store Analysis Results in . bmr Files to Save Having to Reanalyze the Same Stream File Analyze ISDB Partial Reception streams The Buffer Analyzer accepts any recorded Transport Stream as an input source. The TS is then demultiplexed into its component PES, grouped by Program. The user can select one or more PES to analyze for conformance to the T-STD model according to the buffer parameters for the CODEC type in question. General information such as profile and level together with any buffer errors are recorded in a log. The user may manually set buffer sizes and other parameters prior to analysis, rather than use those specified by the standard or signaled within the stream. Buffer Graphs The occupancy level for each buffer within the model (3 for video, 2 for audio, and 2 for PSI) is plotted on a graph for each PES being analyzed. A Synchronization feature allows for comparisons at a particular point in time between each of the graphs and individual log entries. Trace View Version 8. 0 enhancements have integrated the previously separate Tracer utility into the Buffer Analyzer application. The Trace view provides details of the buffer movements for in-depth analysis of the results.
