Harmony 2ES and 4ES 29
Encoding Parameters
Listed below are requirements and recommendations for both
Standard and High Definition encoding, that provide criteria
to create MPEG files compatible with the Harmony playback
system.
1. Files must be one of the following types:
• Program stream MPEG2 or transport stream MPEG2
• System stream MPEG1 of audio/video
• Elementary stream MPEG2
• Video only, MPEG1
• Audio only
2. Use 4:2:0 encoding.
3. With MPEG-2, both audio and video fields must be
encoded. This is the normal default.
4. Audio only (Dolby Digital or MPEG Layer 2) files
cannot be mixed with files containing videos (MPEG,
MPEG2 program stream, video only).
5. Total output per 4-channel card (4ES) can not exceed 40
Mbps.
6. The presentation time stamp (PTS) values contained in
the audio and video streams in a file must be
continuous and increasing.
In particular, the PTS values should not reset to 0 at any
point in the file. The time between the first and last time
stamps in a file should reflect the actual duration of that
file.
Do Not Use 4:2:2 Encoding
