MPEG PS Utils – The Inside of MPEG Program Stream

MPEG PS Utils solution provides a structural representation of a multiplexed MPEG-2 Program Streams, compliant with the ISO/IEC 13818-1 specification. The application allows the user to investigate the basic program stream packets with their fields. The application also allows the user to manipulate with program streams by demultiplexing to PES and ES streams.

MPEG PS Utils Pro offers MPEG Program Stream files verification and validation according to the ISO/IEC 13818-1 standard.

The currently loaded file in the MPEG PS Utils Pro can be validated by selecting “Validation” from the “Tools” menu.

MPEG PS Utils Ultimate is a product extension of the MPEG PS Utils Pro. Along with the standard functionality of MPEG PS Utils and the MPEG Program Stream validation of MPEG PS Utils Pro, the extended product includes AVC/H.264 Video Validation, MPEG-2 Video Validation, AAC Audio Validation and MPEG Audio Validation Modules, which now enables not only the container validation but also the audio and video elementary streams validation. The elementary streams validation process is performed by on-the-fly demultiplexing and verifyication of all audio and video elementary streams subsequently.

The currently loaded file in the MPEG PS Utils Ultimate can be validated by selecting “Validation” from the “Tools” menu.

Apart from the manual MPEG Program Stream, AVC.H264 Video, MPEG-2 Video, AAC Audio and MPEG Audio media validation provided in the MPEG PS Utils Ultimate solution, Jongbel Media Solutions also provides automated media validation of the specified media formats in its Media Validator solution.

The combined validation report output, containing the multiplex and all elementary streams validation information, can be exported into XML report file, having the full report information in standard XML format. This allows easy integration of the solution with any digital media workflow and further processing of the report information with any third party systems.

MPEG PS Utils’s General Info

MPEG PS Utils Pro Main Preview

MPEG PS Utils Pro Main Preview

All container errors, such as mandatory MPEG Program Stream packets absence, incorrect container structure or invalid header values, pointed as mandatory in the corresponding specification are output as Error Report. All container irregularities, which are not pointed as mandatory in the corresponding specification, but have unusual content are output as Warning Reports. Additionally there is a set of Informational Reports, which deliver more detailed information about the file being examined, such as programs details, elementary stream format, media duration, etc.

MPEG PS Validation

MPEG PS Validation

Each MPEG Program Stream container check can be disabled or enabled or set to another report type, such as Info, Warning or Error. The solution can be applied in wide variety of workflows and with many container format deviations due to its flexibility and customization ability.

MPEG PS Validation Advanced

MPEG PS Validation Advanced

The validation report output can be exported into XML report file, containing the full report information in standard XML format. This allows easy integration of the solution with any digital media workflow and further processing of the report information with any third party systems.

The validation takes only a few seconds for an average long and complex media file to be processed.
