A dynamic link library for writing real-time programs to modify tables in ATSC compliant MPEG-2 streams
San Diego , CA - DVEO®, the broadcast division of DVEO, will introduce its PSIP ToolkitT at NAB 2005. The DVEO® PSIP Toolkit is a dynamic link library (dll) designed for writing programs to analyze and modify PSIP tables in real-time. The high level Toolkit is designed to analyze the tables in the PSIP structure and present them to the developer. Once the PSIP tables are presented, several functions are available to modify the tables in real- time.
"With DVEO®'s ATSC Master II PCI bus-based I/O card and a PSIP Toolkit, an application can be quickly written to extract and manipulate data in the PSIP tables," stated Les Zoltan, Sales Manager.
DVEO®'s PSIP Toolkit is an extension of the "Sync API" for the ATSC Master II Card. The "Sync API" is designed as a high level library for OEM's who use the ATSC Master II PCI card as an I/O device for importing or exporting SMPTE 310M compliant transport streams.
Figure 1 shows a typical setup used with the DVEO® PSIP Toolkit. When the toolkit is launched with suitable initial parameters as defined in the API, the application reads in the ATSC compliant MPEG-2 Transport Stream (TS). The TS packet is passed on to the table processor module responsible for analyzing and modifying the tables in the streams. The TS packet is returned back to the application once processed by the table processor module.
DVEO® PSIP Toolkit runs in two modes:
Analyzing Mode: DVEO® PSIP Toolkit is launched by the application through its initialization function provided in the API. Once the DVEO® PSIP Toolkit is initialized, it goes into the analyzing mode and will analyze the tables until the application calls the reset function.
Replacement Mode : DVEO® PSIP Toolkit passes into the replacement mode once the application requests one or more table/tables values to be modified through the API. When modifying tables, DVEO® PSIP Toolkit updates the requested values in the table/tables, increments the version number of the table/tables and updates the MGT if needed with the new modifications. Once a new version of the table is received from upstream, the changes requested by the user are lost.
DVEO® PSIP toolkit is used to build applications to run on Windows 2000 & Windows XP using the Windows Visual C++ compiler. It is an extension of Sync API with "high level" calls to Parse, Examine, and Modify the entries in the major tables found in the ATSC PSIP table structure in real time using DVEO®'s ATSC Master II.
