Menu

Modulator: Allows users to select either QAM or ATSC output
Constellation type used to transmit signal (256QAM, 64QAM)
RF Level Adj: Attenuates the power level of the output signal, in dB, from 0 to -30 dB.
Frequency: Sets the frequency value of the output signal. Important: Check that the selected frequency is not already being used by a current television distribution channel.
Video Profile Settings: The unit comes with a default setting called NORMAL, which provides generally accepted settings for the video profile. If you wish to customize these settings according to your preferences, you can switch to the USER DEFINE mode by clicking on the radio button next to USER DEFINED. 4.1 Min & Max Bitrate: Changes the output video bitrate. Allowed value is 2000 – 20000.
- Latency: Allows users to change the PCR delay time of video. Allowed value is 0-1000.
- GOP: This function Changes the Group of Pictures (GOP) value. The setting will specify the order in which intra- and inter-frames are arranged. If the video being processed does not have a lot of motion, this value should be set to a larger number. For fast motion video, the GOP should be set to a smaller number.However, if the GOP is set too small, the video may jitter. If the GOP is too large the video becomes smoother but may be blurred. The value can be setbetween 1 – 60
- Min & Max Quant: Changes the video detail. The lower the Quant value, the more detail the picture has, but higher relative encoded data rate. If Quant is too small the video may become jumpy. If Quant is too large the video becomes much smoother but may be a little blurred. Allowed value is 1 – 31.
- To improve video quality, you can reduce Min Quant and increase the Max Bitrate.
- To make video smoother, you can increase Max Quant and GOP and reduce the Max Bitrate.
Encode Feature: Changes the encoder feature settings.
- 1080P to I: 1080p video input to 1080i video output.
- Interlace Enc: Changes the video encoder method. For 1080i and progressivevideo input, “I Field” is suggested. For 480i/576i video input, please use I Frame Mode.
Audio Codec: It can change the audio codec between MP1 Layer II, AAC-LC and AC3.
PMT PID: Changes the PMT (Program Map Table) PID. Allowed value is 0001~8191.
Video PID: Changes the Video PID. Allowed value is 0001 – 8191.
Audio PID: Changes the Audio PID. Allowed value is 0001 – 8191.
PSIP TSID: PSIP TSID edit.
Channel Mode: Changes the channel between DTV channel (two-part channel number) and Loop channel (one-part channel number).
Major No.: Major no. edit.
Minor No.: Minor no. edit.
Short Name: Short name edit.
Long Name: Long name edit.
Source ID: Source ID edit.
