Product Description

Multiplexing is used for encapsulation of multiple Audio, Video, and Data services and Control information in Multiplex Frames (MMB Part 1, 2).

The main functions of the multiplexer are to receive the incoming data, prepare control and service information tables, encapsulate the data in frames depending on the data type and classification criteria, schedule time slots maintaining appropriate FIFO levels, and distribute the service and control tables multiplex in the MPEG-2 TS packets to the modulators through the ASI interface.

The multiplexer can be used in two possible cases. At the head end as a central multiplexer of global services, multiplexing simultaneously one or two networks (1), or locally as a multiplexer of local content (2). The multiplexer is designed to satisfy the requirement in both modes and operate in any one of them with minimal configuration.
