the Blackmagic Design Spares - Smart Videohub 20x20 - PCB Main is the core routing engine and logic board for the Smart Videohub 20x20 mixed-format router. As a massive 6G-SDI cross-point matrix, this board manages the complex task of simultaneously routing any of the 20 inputs to any of the 20 outputs in any combination of SD, HD, and Ultra HD formats.

High-Bandwidth 6G-SDI Crosspoint

The Main PCB is engineered around a sophisticated crosspoint switch that maintains signal integrity across all 40 BNC connections. It is designed to handle "clean switching" requirements, ensuring that the router can transition between different video standards on different ports without interference.

  • Mixed Format Routing: The board allows you to connect a mixture of SD, HD, and Ultra HD equipment on the same router at the same time.

  • SDI Re-clocking: Every single output on the PCB features dedicated re-clocking, which regenerates the SDI signal to reduce jitter and allow for maximum cable lengths.

Integrated Control and Network Logic

This board does more than just route video; it acts as the central communication hub for the entire Videohub ecosystem.

  • Ethernet Control: The Main PCB hosts the web server and network protocols that allow the router to be controlled via the Videohub Software Control on Mac and Windows, or via hardware Videohub Smart Control panels.

  • Front Panel Interface: It manages the communication with the front panel (often a separate assembly) that houses the LCD, spin knob, and buttons for local crosspoint changes.

  • Serial Port (RS-422): Includes the logic for external router control protocols, common in automated broadcast environments.

Power Distribution and Redundancy

The Smart Videohub 20x20 is designed for "mission-critical" environments. The Main PCB features robust power regulation to ensure that the 6G-SDI chips—which generate a significant amount of heat—receive stable voltage. It is designed to work in tandem with the internal power supply units to provide 24/7 reliability in a broadcast rack.

Key Features

  • Genuine OEM Spare: Specifically for the 20x20 model (not interchangeable with the 12x12 or 40x40 versions).

  • Full 6G-SDI Bandwidth: Supports resolutions up to 2160p30 on every port.

  • Reference Input Logic: Houses the circuitry for Black Burst and Tri-Sync input to ensure all routed signals stay in sync with the house clock.

  • Ruggedized BNC Array: Features 40 high-quality, chassis-grounded BNC connectors soldered directly to the board.

Technical Installation Note

Replacing the Main PCB on a 20x20 router is a major technical operation due to the density of the hardware:

  • BNC Alignment: The most challenging part of the installation is aligning the 40 BNC ports with the rear metal plate. All ports must be perfectly seated before the plate is screwed back on to avoid putting stress on the solder joints.

  • Cooling and Airflow: The 6G-SDI crosspoint chips are covered by large heat sinks. When installing the new board, ensure the internal fans are functioning and that the airflow paths across these heat sinks are completely unobstructed.

  • IP Configuration: Upon first power-up, the new board will revert to factory default network settings. You will need to connect via USB or the default IP to re-configure the router for your specific network.

  • Static Hazard: Because this board contains an massive array of sensitive SDI drivers and an FPGA, it is highly susceptible to ESD (Electrostatic Discharge). Work only on a grounded anti-static mat.

Bulky
I was a little disappointed in how bulky these were and seemed hard to get on. If you can get past this they do seem to work good. Hands do seem softer and a bit healthier.

Really moisturizes hands
These gloves really work. My cuticles and hands alway seem dry. I used these gloves the first night I received them and my hands were really smooth afterward. When I get in bed at night, I play on my computer and iPad, and these gloves are perfect. The end of the index finger is designed to be used with a phone, computer, and iPad. Make sure you push the end of the fingers on the gloves all the way down to the end of your fingertips; otherwise you will not be able to use them with a device. I find they work better with my iPad than my computer. I have not tried to use with my phone. The gloves are not uncomfortable, but I found they are not comfortable to wear all night, so I just try to wear them about an hour every night. I wish I had these gloves about 20 years ago and my hands would probably look like a 20 year old.

So much pain
I had to remove these after less than 5 minutes as they caused such intense pain. The gel clings to your skin even with the lotion and tightens around your hands cutting off circulation. They have been off for about half an hour and my hands still hurt. I was so excited as I really like this brand in general. Very disappointed. Be very aware when buying.

Moisturizing Gloves That Actually Work
Over the years, I have tried so many different types of gloves to alleviate my dry skin. Since it especially bad on my hands I have tried everything. Of all the gloves I have purchased, this pair is head and shoulders above all the others. The first night I used these I could not believe the difference! It was astonishing. My hands were soft and supple for the first time in my life, and they stayed that way for most of the day. The moisturizing aspects of leaving humectants on one's skin for prolonged periods is really a game changer. They fit perfectly and can be pulled on with ease. The crazy bonus is that I was still able to use my phone once I was wearing them. That has never been the case with any of the other gloves I've used. If you have dry skin on your hands, you must try these. One night of use and you will be sold!

A bit small for one size fits all
Purchased these for my husband who has pretty severe dry skin in the winter. The gloves are great but they are a bit small. My husband doesn’t have very large hands (cadet size golfing gloves) & this hardly reaches his wrist so one size fits most is a bit of a stretch. However, these do the job & he likes them. We appreciate the packaging doubles as a reusable pouch.
