Since it is not currently possible for the join/replace or append operations to detect “-3dB Rear
Channel Attenuation”, “ES Phase Shift” and “Downmix Coefficient" discrepancies between
encoded streams, it is the responsibility of the user to avoid joining streams that do not match in
this respect, DTS recommends that users NOT join encodes that differ in this fashion
 Audio to timecode synchronization cannot be maintained by the Join/Replace operation
if the selected DTS-HD file has been restriped (see 10.5 Restripe Tool).
In conclusion, the Join operation has an advanced rule set that guarantees audio to timecode
synchronization and bit exact editing, as long as the encoded streams used have not been restriped.
Summary of JOIN requirements
 Overlapping audio regions must be present at join points. The audio contained in the
overlapping region MUST be bit for bit identical. Overlapping regions must be at least 1
second in length and MUST be present before and after the intended join time in order
for a join /replace operation to be permitted.
 Encode 2 must be encoded with a Reference Time equal to the reference time of Encode
1.
 Only DTS-HD encoded streams with matching stream characteristics can be joined.
 Audio to timecode sync cannot be maintained by the Join/Replace operation if the
selected DTS-HD file has been restriped.
DTS Express (LBR): The use of DTS Express (LBR) encoded streams is only permitted with
the Verify tool.
