MP2TSMM
MPEG-2 Transport Stream Multiplexer for Multiple Programs

Manzanita's MPEG-2 Transport Stream Multiplexer for Multiple Programs (MP2TSMM) is the leading application for offline creation of transport streams.

MP2TSMM has been selected by major players in digital post-production, VOD, and advanced television services for their transport stream generation. Its powerful feature set and robustness have enabled MP2TSMM to support a variety of applications and meet specific system requirements. The strict adherence to compliance in the MP2TSMM design and its proven track record give users confidence in the quality and validity of the output.

MP2TSMM provides the technology to create transport streams for many applications, including:

• Server Content Creation - Stored elementary streams can be multiplexed to create custom programs for a server archive.
• Remultiplexing - Transport streams may be remultiplexed with the aid of the demultiplexer function to correct faulty streams created by a non-compliant multiplexer.
• Elementary Stream Addition - An existing transport stream can be demultiplexed, and then remultiplexed with additional elementary streams. For example, a program may be supplemented with an alternative audio stream.
• Private Data Insertion - Prepacketized data streams may be inserted at a specified rate into the transport multiplex as system information or program elements.
• Legacy Content Processing - System or program stream archives can be demultiplexed, and then remultiplexed as transport streams to avoid the expense of re-encoding.

General Features
