Professional, Cost Effective, Multichannel, TS Multiplexer with 8 DVB-ASI Inputs -- Combines 2 to 8 MPEG-2 and/or H.264 Transport Streams, SPTS or MPTS. Features Two ASI Outputs. Automatically Re-generates PSI and SI Tables. PSI/SI Generator Support for DVB Table Editing. Able to Insert Electronic Program Guides and Other Data. Can be Used to Edit Existing PSIP Tables. Useful for Removing Services from MPTS Streams.
