1) DVB-T: modulating standard; XX.XXX MHz: the current output frequency; U: symbol
of the USB disk insertion; 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) Video Parameters: User can enter the items respectively to set video parameters.
Interface: select a right interface type from the options provided. The device then can
automatically search the signal and starts to encode. Resolution: signal source
resolution, read-only. Video Bit rate: adjust in range of 1.000~19.000 Mbps. Video
Format: this unit supports mpeg2 and h.264 video encoding format in CBR/VBR bitrate
control mode. User can also adjust values of rest items (Brightness & Contrast &
Saturation: 0-255; Hue: -128 - +127)
5) Audio Bit rate: Select audio bit rate among 64, 96, 128, 192, 256, 320, 384 kbps.
Audio Format: Select audio format among MPEG2, MPEG2-AAC and MPEG4-AAC.
6) Program Information: User can enable or disable the program output under menu
Program Output. User can also enter the other items to edit the Service Name, Program
Name, Program Number, and PIDs of PMT, PCR, Video and Audio, and edit LCN
(Logical channel number). EIT Event – User can enter this menu to setup EIT (Event
Information Table) for the current and next program event. The EIT contains Start Year,
Start Time, Duration, and Event Name of the event. All the EIT information can be
displayed on the TV screen on condition that the EIT is chosen to insert (see
explanation 19.).
7) Bandwidth: choose between 6M, 7M and 8M.
8) Constellation: DVB-T modulator contains 3 constellation modes – 64 QAM, QPSK
and 16 QAM.
9) FFT (Transmission Mode): Select between 2K and 8K.
10) Guard Interval: Select among 1/32, 1/16, 1/8 and 1/4.
11) Code Rate: It refers to FEC-Forward Error Correction rate. It contains 1/2, 2/3, 3/4,
5/6 and 7/8.
NOTE: The different combination of bandwidth, constellation, guard interval and
code rate (FEC) will form a different output code rate. Please refer to appendix
