The 7555 HD Processing Frame Sync accepts a 1.5 Gb/s high definition video or standard definition video signal for processing, synchronization and timing.
An infinitely adjustable timing system genlocks to your house reference. The 7555 genlocks to either composite video (PAL or NTSC) or to Tri-Level Sync. The module can lock to the frame’s master reference or reference can be connected directly to the module’s external reference BNC. The serial output timing can be set anywhere within a frame of the selected input reference, which can be the module’s external BNC reference or the frame’s master timing reference.
Upon loss of signal, the 7555 provides freeze frame or black until the signal is recovered. In freeze mode, audio can be muted or passed as desired.
The HD or SD SDI input is carried at full, uncompressed bandwidth throughout the entire module.
The 7555 has a full-featured Proc Amp for adjustment of every signal parameter. Proc controls include Video and Chroma Gain, NTSC-style hue rotation, Black Balance, and Pedestal.
The 7555 includes a full-featured, sixteen-channel audio mixer. The channel swap and shuffle capability allows you to completely rearrange and remix audio channels. It provides precise control over audio level, with up to 12 dB of gain to compensate for low level sources. Delay is adjustable up to one second. The audio mixer can be used for embedded audio and for audio sourced from the AES or analog inputs. The 9615 AES and analog audio I/O software key option is required if you want to use the AES or analog inputs and outputs. The 9615 provides four AES input/output ports for eight channels of I/O and also provides four channels of analog audio I/O.
The 7555 can be fitted with Dolby™ and AC-3 encoding and decoding options. The 7615 decoding option can be fed from either an AES input or an AES stream disembedded from the incoming SDI signal. The resulting discrete surround signals are then selectable as inputs to the sixteen channel mixer/shuffler.
The 7630 Dolby encoder is fed from selected outputs of the sixteen channel mixer/shuffler. The resulting encoded bitstream can be output both on an AES output and embedded into the
SDI output.
The 9670 LevelTrack™ Audio Automatic Gain Control software key can be added as an option. LevelTrack provides control for keeping audio levels consistent in program material.
The 9690 Audio Compliance and Monitoring Software can be added for compliance verification and archiving.
Every function and parameter on the 7555 can be controlled from an Avenue Touch Panel or the Avenue PC Control Application. Memory registers can be used to save the complete configuration of the module, making it easy to change instantly between different configurations.
