Appendix B: An Introduction to MPEG

Rev. 6.4 

 

Transport Stream 

A transport stream is another MPEG 2 mechanism for combining audio and video elementary streams. It has the 
following two differences from Program streams: 

• 

The packet size is much smaller, therefore allowing easier recovery from bit errors in the stream. 

• 

The transport stream can contain any number of different audio and video stream pairs. 

 

Transport streams were designed for the Television broadcast industry where errors may be common in the data 
streams transmitted from satellite, and there may be many different TV channels broadcast in the same stream. 

Note: The MediaSonic HD Player requires all MPEG files to be multiplexed as transport streams. Please refer to 
the encoding guidelines for full details of mastering content.
