The MPEG-2 Program Stream 

The Information Station plays MPEG-2 Program Streams.  This stream is a 

Variable or Constant bitrate stream containing both audio and video.  In order to 

achieve playback of video only, you must encode an elementary stream of silent 

audio that will be combined with your elementary video stream to create a 

program stream.   A program stream is not the same as a DVD VOB file.  The 

Information Station does not play VOB files. 

What is a Variable Bitrate? 

Unlike MPEG-1, which uses a constant bitrate, MPEG-2 also supports variable 

bitrate program streams.  This means that the encoding process scales the bitrate 

up and down depending on quality needs.  A scene with a tremendous amount of 

movement requires more bits than a still scene. 

 

Program Stream: 

Mux Bit Rate: 

15.0 Mbits/s max 

The stream should be authored according to ISO 13818-1 Format 

MPEG-2 Video: 

Picture Format 

SIF-NTSC: 240 lines by 352 

pixels 

 

SIF-PAL: 288 lines by 352 pixels

pixels 

 

HalfD1-PAL: 576 lines by 352 

pixels 

 

CCIR-NTSC: 480 lines by 704(or 

720) pixels 

 

CCIR-PAL: 576 lines by 704(or 

720) pixels 

Chroma Format  4:2:0 

MPEG-1 Audio (Layer II):
