Options, Licensing and Upgrades
If the appropriate licenses are available, up to 8 channel pairs of audio can be
encoded using the MPEG-1 Layer II algorithm, 3 audio channel pairs can be
encoded in Dolby Digital or 6 channel pairs in AAC LC or HE-AAC. There is also an
option to configure the unit to pass-thru pre-encoded Dolby Digital, Dolby-E or
Linear PCM audio.
The VCM is also capable of processing VBI from the analogue input and ANC and
VBI from the SDI input.
7.4.4.2 Inputs
This module provides the following inputs:
• HD/SD SDI Input via a 75 Ω BNC female connector.
• Analogue video input via a 75 Ω BNC female connector.
• Digital audio input via a 15-way D-Type male connector (see Chapter 2 Installing
the Equipment)
• Analogue audio input via a 15-way D-Type male connector (see Chapter 2
Installing the Equipment).
• Video.
Table 7.6 Analogue Video Standard Parameters
Standard Number of Lines Frame Rate Video Bandwidth
NTSC - M (without pedestal) 525 29.97 frames/s 4.2 MHz
NTSC - M (with pedestal) 525 29.97 frames/s 4.2 MHz
PAL - B 625 25 frames/s 5.0 MHz
PAL - G 625 25 frames/s 5.0 MHz
PAL - H 625 25 frames/s 5.0 MHz
PAL - I 625 25 frames/s 5.0 MHz
PAL - D 625 25 frames/s 5.0 MHz
Note: Reduced horizontal resolutions are configurable on the VCM but are not
recommended for contribution feeds. If selected, the reduced resolution
must also be supported by the decoder.
7.4.4.3 Input Detection
When encoding analogue video source, the unit is not able to automatically detect
the input video format. Instead, the user must set the correct format through the user
interface and the unit will update the locked state accordingly.
Input auto detection works for digital video input through the SDI/HD-SDI connector.
7.4.4.4 Ancillary Data
The following ancillary data is supported only when the unit is fed by a digital video
