CONCLUSIONS (I)
23 DTMB receivers were tested. There were found
decoding and visualization deficiencies in the EPG
information, regarding the content and extended_event
descriptors.
LACETEL will update the Evaluation Procedure. All the
manufacturers will be notified.

CONCLUSIONS (II)
The employment of the currently unused descriptors by the
content generator would allow an improvement in the
reception of Electronic Program Guide service.
