12-bit 3D adaptive color decoding and 12-bit color encoding.
Noise reduction option.
Frame synchronization and time base correction for non-synchronous signals.
Analog-to-digital and digital-to-analog video conversion for hybrid facilities.
Up or down conversion with aspect ratio conversion for hybrid standard and high definition facilities.
High definition cross-conversion for broadcast and production facilities with multiple high definition
format requirements.
(Optional) Simultaneous up and down or simultaneous cross and down conversions for hybrid systems
applications.
Audio Processing
Processing for audio includes:
Level/invert/delay controls.
Analog-to-digital and digital-to-analog conversion.
Embedding and de-embedding for both SDI and HD-SDI serial digital signals — for interfacing any
audio signal in a professional environment.
Sample rate conversion, synchronization and timing to video — for lip-sync error correction.
Decompression and processing for embedded, compressed audio signals such as Dolby E and AC-3.
Multi-channel program signal processing for surround sound applications — before or after
compression.
Audio follow video feature to switch the audio source to a matched video input source.
Audio summing and voice-over.
Input and output matrices for channel swapping and assigning inputs to outputs.
Metadata
Embedded metadata within the program stream (e.g., CC [Closed Captioning]) is passed transparently from input to
output for standard definition processing. During upconversion, EIA-608 is transcoded to EIA-708 from input line
21 to output line 9. The reverse process takes place during downconversion. For cross conversion EIA-708 is
passed through.
Control and Monitoring
Control and monitoring of signals passing through the
X75
is enabled using IP over Ethernet. Instant operator
control from the local or remote control panels allows easy manipulation of video and audio signals. The use of two
Ethernet ports per unit (one for control, monitoring and video thumbnails, and one for video and audio streaming)
makes PC control and monitoring over large networks entirely manageable. A built-in Web Server and optional
SNMP (Simple Network Management Protocol) are industry standard means of controlling and monitoring the
X75
over Ethernet. Leitch’s CCS (Command and Control System), Co-Pilot and Navigator software further enhance the
remote control aspects of the
X75
.
