Audio Bitrate:
[64..320..384 kbps] This determines the audio data bit rate. It is an element of the system bit rate.
Audio Mode:
[Stereo/ Joint Stereo/ Dual Channel/ Mono/ use VPS]
identifies the type of audio data.
“use VPS“ adopt the identification transferred within the VPS signal into the MPEG data stream (audio header).
Audio Typ:
[PCM
→
MP-2, PCM
→
AC3, AC3 pass through, PCM
→
E-AC3 (DD+), E-AC3 pass through]
„PCM
→
MP-2“:
Sound signal is changed in MPEG-1, Layer 2 format (DVB standard)
„PCM
→
AC3“:
Sound signal is changed in AC3 format
(available in EMA 508, 608)
„AC3 pass through“: An AC3 sound signal existing in input signal is adopted into the output signal.
(available in EMA 408, 508, 608, 708)
„
PCM
→
E-AC3 (DD+)“: Sound signal is changed in E-AC3 (DD+)
(available in EMA 508, 608)
„E-AC3 pass through“: the in the input soignal included E-AC3 signal is applied to the output signal.
(available in EMA 408, 508, 608, 708)
Audio Channel Pair (SDI):
[1/2 .. 15/16]
When SDI with embedded audio is being transmitted, it can be selected an audio signal pair for the processing.
‚dB‘ Audio Volume (SDI):
[-6..0..6]
Decrease or increase the audio level.
Audio Input Impedance (analogue):
Input impedance switch: 600
Ω
/ 10 k
Ω
Audio Input Level (analogue):
Adjustment of the audio level at the input.
TTX Processing:
[OFF, Video IN, Intern (ViTex)]
“OFF“
Feature deactivated.
“Video IN“
The teletext of the video input signal is converted to DVB compliant data packets and is transmitted in the TS.
“Intern“
With additional software (Vitex), a separate teletext can be generated (only available for SD video signals).
VPS-WSS-CC:
[OFF/ VPS/ WSS/ VPS+WSS/ Closed Captions]
VPS and/ or WSS lines of the video input signal are converted to DVB compliant data packets and transmitted in the transport
stream. For NTSC input signals “Closed Captioning“ can be processed - only available for SD video signals
(available in EMA 308, 407).
