3.3.2.2.4 Slot A (Input-A) parameters
All the following setting notes apply equally to encoders B ... D.

(EMA 408, SDI input signal)
(EMA 308, analogue input signal)
Program Name:
Assignment of a name for each imported or transformed program. The program name is displayed on the terminal equipment
(TV). The program name must be unique and may appear only once in a cascade of encoders. The maximum length is
16 characters.
Program Language:
[deu, eng, ...]
Identifies the language for the audio data stream and teletext. It should be designated as per ISO 639-2 [4].
Video System:
[
PAL/ SECAM (50 Hz), NTSC (60 Hz), OFF (Digital Radio), OFF (Audio Channel)]
Sets the type of the input video signal. The following signal types are processed: at 50 Hz/ 25 fps - PAL (B, D, G, H, I, N, Nc)
and SECAM; at 60 Hz/ 30 fps - NTSC (J, M, 4.43) and PAL (M, 60). In the “OFF-Radio” setting, the video signal is ignored and
a digital radio channel is generated. With the “Table Extension“ this can be assigned to other encoders as an additional audio
channel.
Video Format (MPEG-2):
[
4:3, 16:9, use WSS]
This is how the means of interpreting the video input signal for the MPEG header is established. In respect of “use WSS“, only
the “16:9 Fullformat“ is evaluated. Anything else will be transmitted as 4:3. Condition: VPS-WSS = WSS or VPS+WSS
System Bitrate:
[1000..6000..15000 kbps]
Here the bandwidth is established for audio, video and table data in the relevant encoder (slot). The value is only an upper
limit. The bit rate actually generated will be slightly slower and will not be absolutely constant.
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]
Here the type of audio data is identified.
“use VPS“
here the identification transferred within the VPS signal is taken over into the MPEG data stream as audio header.
Video Format (H.264/ AVC):
[SD 625/525/ HD 720p (1280x720), HD 1080i (1920x1080)]
The chosen configuration must reflect the actual parameters of the encoder input signal.
Audio Typ:
[PCM-->MP-2, PCM-->AC3, 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)
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 ohms/ 10 kohms
