SPMux - MPEG System & Program Stream Multiplexer

The MPEG System & Program Stream Multiplexer (SPMux) is an easy-to-use, versatile tool for rapid creation of MPEG-1 system streams and MPEG-2 program streams.

SPMux offers the flexibility to satisfy the needs of users in both limited test environments and large-scale production.

As in all of our products, our design emphasis in SPMux is to insure that the output is fully compliant with the MPEG standard and interoperable in every environment. All system clock information and time stamps in the stream are precisely computed. The resultant stream is verified with the decoder buffer model that is specified by MPEG to guarantee that there are no timing or buffer violations.

Applications for SPMux include VOD, DVD, hotel and in-flight entertainment, kiosk video, and intranet/internet streaming video.

General Features

• Generates fully compliant MPEG-1 system streams and MPEG-2 program streams
• Defaults are selected for all stream parameters so only input and output file names are required
• Simple configuration file format
• Command line execution and batch processing ability
• Output stream is verified with the decoder buffer model specified by the MPEG standard
• Accepts up to 16 MPEG-1 and/or MPEG-2 video elementary streams
• Supports both constant bit rate and variable bit rate video
• Accepts up to 32 MPEG and/or Dolby AC-3 audio elementary streams
• Displays a summary of output stream characteristics

System Requirements

SPMux is available for Windows (2000, Server 2003, or XP), Linux (i386+ compatible, X11 R6.8 or newer), Solaris (8 or newer on Sparc), and Mac OS X (v10.3 or newer).

Technical Support

Purchase of SPMux includes one year of free technical support and software updates.

Demo Version

Download a free demonstration version of SPMux. The Demo version supports all of the features and functions of the full version, but the output stream is limited to 10 seconds. A copy of the SPMux User's Manual is also included. If you would like the SPMux Demo for a different platform, please send email to: spmux@manzanitasystems.com.

SDK

Do you need an off-the-shelf MPEG system or program stream multiplexing core for your realtime or offline application? We also offer an SPMux Software Development Kit. We will work closely with you to develop an API if you have custom requirements.
