Abstract
Methods and apparatus are disclosed to broadcast advanced television system committee (ATSC) video in switched digital video (SDV) systems. An example SDV broadcast method includes de-multiplexing at least one program stream from at least one of a plurality of multiple program transport streams (MPTSs), and connecting at least one program stream to a SDV broadcast engine.
Claims20
A method for broadcasting program streams in a switched digital video (SDV) system that receives a plurality of motion picture experts group (MPEG) multiple program transport streams (MPTSs) comprising:
- configuring a de-multiplexer to de-multiplex at least one of the plurality of MPTSs into a plurality of program streams;
- and
- configuring a switch to deliver the plurality of program streams to respective ones of a plurality of SDV broadcast engines.
For use in broadcasting motion picture experts group (MPEG) Multiple Program Transport Streams (MPTSs) in a Switched Digital Video (SDV) system, a switched digital video (SDV) switch comprising:
- at least one de-multiplexer to de-multiplex at least one program stream from at least one MPTS;
- and
- at least one cross connection switch to connect at least one program stream to at least one SDV broadcast engine.
A switched digital video (SDV) system for broadcasting motion picture experts group (MPEG) Multiple Program Transport Streams (MPTSs), the SDV system comprising:
- a system manager to select program streams to be broadcasted via the SDV system;
- a proxy server in communication with the system manager to provide program identification information to the system manager and to receive program selection instructions from the system manager;
- and
- a SDV switch responsive to the proxy server to route program streams selected by the system manager to respective ones of a plurality of SDV broadcast engines selected by the system manager.
