9.10.2 Passive Standby State
The set is in standby mode. The module is in off state.
9.10.3 Active Standby State
The set is in "Semi-Standby" mode. All the circuits in the set,
except the audio output and the LCD display are powered up
and fully active. The set appears to be in normal standby mode
for the customer.
The module is in "On" or "Logical Standby" state.
•
On state. In this state the module can perform the following
pre-programmed functions:
–
VCR (digital program) records
–
EPG updates
–
Over-the-air software download signaling detection
and software downloads
•
Logial Standby state. In this state only over-the-air
software download signaling detection and software
downloads can be performed.
9.10.4 On State
The set is fully functional and the module is powered up. The
module is in "On" or "Logical Standby" state.
•
On state. In this state all system functionality is available or
the module is in software downloading process.
•
Logial Standby state. In this state only over-the-air
software download signaling detection and software
downloads can be performed.
