1
) DVB-T: modulating standard; XX.XXX MHz: the current output frequency; 1080i: video
resolution of signal source; X.XX Mbps: the current encoding bit rate
2
) Alarm Status: For example, if the signals lose, it will give alarm and display error type
under this menu. For example:
Video 1 Not Lock
3
) Uptime: It displays the working time duration of the device. It times upon power on.
4
) Encoder Parameters: User can enter the items respectively to set Encoder parameters.
Video in Status
: User can view the video status under this menu.
Resolution
: signal source
resolution, read-only.
Video Bit rate
:
adjust in the range of 1.000~18.000 Mbps
.
Audio Bit
rate:
Select audio bit rate among 64, 96, 128, 192, 256, 320kbps.
Audio Format:
audio
format is default to MPEG-1 Layer 2.
5)
Stream: User can view or adjust TSID, ONID, Network ID, Network Name, Provider
Name, Program number, LCN (Logical channel number), PMT PID, Video PID and audio
PID after enter this menu.
6)
Country: User can choose country under this menu. There are three options Default,
Australia or New Zealand. If user chooses Default, modulating parameters need to be set
manually through advanced configuration. If choose other two, user do not need to set RF
frequency, Bandwidth, Constellation, FEC, FFT, Guard interval and RF Level. It will
configure automatically according to the Country. It is a shortcut.
7)
Channel: User can choose Channel under this submenu.
8
) Bit Rate: User can read the current modulating bit rate and the maximum bit rate
9
) RF Frequency: Adjust it at range of 142.5 MHz to 858 MHz. Set it according your regional
situation or inquire your local services.
10
) Bandwidth: choose between 6M, 7M and 8M.
11
) Constellation: DVB-T modulator contains 3 constellation modes – 64 QAM, QPSK and
16 QAM.
12
) FEC: Forward Error Correction rate. It contains 1/2, 2/3, 3/4, 5/6 and 7/8.
13
) FFT (Transmission Mode): Select between 2K and 8K.
14
) Guard Interval: Select among 1/32, 1/16, 1/8 and 1/4.
15
) RF Level: Adjust it at range of -14~ +6dBm.
Ø
NOTE
: The different combination of bandwidth, constellation, guard interval and FEC
(code rate) will form a different output code rate. Please refer to appendix table 2. To
ensure the output image quality, it is required the output code rate to be higher than
22 MHz.
