Lawo’s V__pro8 eight-channel video processing tool has received a comprehensive software revision, bringing an updated A/V sync tool which, in addition to the native V__line sync pattern and the EBU pattern, can read the Vistek VALID8 format. The integrated quad-split multiviewer now also features multi-coloured Tally lamps, which are switchable via Ember+, allowing integration of the MV tally in the overall tally system of an installation.
The 1U-high V__pro8 interconnects different video formats as well as bridges between audio and video, with high-quality format conversion and colour correction, as well as audio embedding and de-embedding.
Its video/audio router provides an internal 8x8 video routing matrix and a 384x384 audio matrix, while frame synchronisers align incoming independent free-running signals to the same reference (Blackburst or TriLevel). Variable video and audio delays compensate for latencies and lip-sync incoming or outgoing audio (up to 320ms delay) and video (up to eight frames delay). An internal AudioFollowVideo delay mode automatically compensates for internal video latency.
The V__pro8 provides De-embedders with SRC to embed, de-embed and shuffle any of the 16 audio channels within the eight SDI input/output streams, simultaneously and interfacing the audio to mixing consoles or external audio routers via MADI. The Dolby E Auto Aligner, meanwhile, automatically adjusts the timing of Dolby streams. In addition, the V__pro8 can be enhanced with a Dolby E Encoding/Decoding option, providing fully compatible en-/decoding of professional multichannel audio on a single AES3 connection with Dolby E metadata handling.
The surround Downmix provides two automated Lawo-quality 5.1/7.1 to stereo downmixes per embedder. With the time code insertion capabilities, users can choose between ATC LTC/VITC1 / VITC2 insertion from an input signal or free run mode or from internal time-code generator. The test pattern and video ID generator provide video ID insertions (text, source, date, time code, time of day) and colour bar test pattern as well as a selection of audio test tones and AV Sync test pattern. The unit can be further enhanced with optional features such as high-quality up/down/cross and AR format converter, quadsplit multi-viewer, waveform and vectorscope displays, RGB & YUV colour-correction and proc-amp.
The V__pro8 can be configured via the optional V__fp1 front panel with an integrated headphone connector and a high-res OLED display that provides thumbnail motion previews of video signals as well as direct configuration of the unit. Alternatively, the unit can be configured by an HTML 5-based touchscreen-optimised web GUI. This provides thumbnail previews of all incoming and outgoing signals and due to its web-based approach enables the user to access all V__line devices from anywhere within the network — a feature especially useful in larger set-ups or in larger installations with long-distance links.
The V__pro8 fully supports the Ember+ protocol, enabling the device to be controlled by external master control systems, as for instance Lawo’s VSM. This allows operators to easily access multiple device parameters along with other routing parameters of the installation via a single, integrated interface. In addition, they get access to the V__pro8’s thumbnails and peak meters within the VSM desktop environment.
