Black Box Explains...Digital Visual Interface (DVI) cables.
The Digital Visual Interface (DVI) standard is based on transition-minimized differential signaling (TMDS). In a typical single-line digital signal, voltage is raised to a high level and decreased to a... more/see it nowlow level to create transitions that convey data. To minimize the number of transitions needed to transfer data, TMDS uses a pair of signal wires. When one wire goes to a high-voltage state, the other goes to a low-voltage state. This balance increases the data-transfer rate and improves accuracy.
There are different types of DVI connectors: DVI-D, DVI-I, DVI-A, DFP, and EVC. DVI-D is a digital-only connector.
DVI-D is a digital-only connector. DVI-I supports both digital and analog RGB connections. Some manufacturers are offering the DVI-I connector type on their products instead of separate analog and digital connectors. DVI-A is used to carry an analog DVI signal to a VGA device, such as a display. DFP, like DVI-D, was an early digital-only connector used on some displays; it’s being phased out. EVC (also known as P&D) is similar to DVI-I only it’s slightly larger in size. It also handles digital and analog connections, and it’s used primarily on projectors. collapse

This video discusses content supported by the iCOMPEL™ digital signage player, including the types of formats for movies and images, as well as the type of text (fixed, scrolling, and... more/see it nowRSS feed) and HTML. It outlines recommended ways of getting text into the platform’s text editor. It also discusses what’s needed for repurposing PowerPoint® content for your signage. collapse
Black Box Explains... Speaker wire gauge.
Wire gauge (often shown as AWG, for American Wire Gauge) is a measure of the thickness of the wire. The more a wire is drawn or sized, the smaller its... more/see it nowdiameter will be. The lower the wire gauge, the thicker the wire.
For example, a 24 AWG wire is thinner than a 14 AWG wire. A lower AWG means longer transmission distance and better integrity. As a rule of thumb, power loss decreases as the wire size increases.
When it comes to choosing speaker cable, consider a few factors: distance, the type of system and amplifier you have, the frequencies of the signals being handled, and any specifications that the speaker manufacturer recommends.
For most home applications where you simply need to run cable from your stereo to speakers in the same room—or even behind the walls to other rooms—16 AWG cable is usually fine.
If youre considering runs of more than 40 feet (12.1 m), consider using 14 AWG or even 12 AWG cable. They both offer better transmission and less resistance over longer distances. You should probably choose 12 AWG cable for high-end audio systems with higher power output or for low-frequency subwoofers. As a rule of thumb, power loss decreases as the wire size increases.
To terminate your cable, choose gold connectors. Because gold resists oxidation over time, gold connectors wear better and offer better peformance than other connectors do. collapse
Video...iCOMPEL™ demo: How to use this hardware/software platform to create compelling digital signage.
Hosted by George Borden, Digital Signage National Sales Manager for Black Box, this video shows how the all-inclusive iCOMPEL™ platform can be used to set up professional signage for engaging... more/see it nowcommunications. The video begins with a discussion of the various signage elements (layouts, zones, playlists, and schedules) and how they’re used to create compelling signage. Then, in the live demo portion of the video, he demonstrates how to use its user-friendly interface to set up a layout, load media in zones, drag and drop media into position within a zone, and create and manage playlists. The video also shows how to update content ad-hoc at a screen, bring in RSS feeds, assign an override message for emergency alerts, and more. collapse
Black Box Explains...USB 2.0 and USB OTG.
The Universal Serial Bus (USB) hardware (plug-and-play) standard makes connecting peripherals to your computer easy.
USB 1.1, introduced in 1995, is the original USB standard. It has two data rates:... more/see it now12 Mbps for devices such as disk drives that need high-speed throughput and 1.5 Mbps for devices such as joysticks that need much lower bandwidth.
In 2002, a newer specification, USB 2.0, or Hi-Speed USB 2.0, gained wide acceptance in the industry. This version is both forward- and backward-compatible with USB 1.1. It increases the speed of the peripheral to PC connection from 12 Mbps to 480 Mbps, or 40 times faster than USB 1.1!
This increase in bandwidth enhances the use of external peripherals that require high throughput, such as CD/DVD burners, scanners, digital cameras, video equipment, and more. USB 2.0 supports demanding applications, such as Web publishing, in which multiple high-speed devices run simultaneously. USB 2.0 also supports Windows® XP through a Windows update.
An even newer USB standard, USB On-The-Go (OTG), is also in development. USB OTG enables devices other than a PC to act as a host. It enables portable equipment—such as PDAs, cell phones, digital cameras, and digital music players—to connect to each other without the need for a PC host.
USB 2.0 specifies three types of connectors: the A connector, the B connector, and the Mini B connector. A fourth type of connector, the Mini A (used for smaller peripherals such as mobile phones), was developed as part of the USB OTG specification. collapse
Video...MediaFlyer™ demo: How to use this Web-based platform to set up impressive digital signage on the fly.
Hosted by George Borden, Digital Signage National Sales Manager for Black Box, this video shows how simple it is to create digital signage using MediaFlyer™, our SaaS-based solution for monitoring... more/see it nowand managing single-screen or a multiscreen deployments. In the demo, he discusses the many media formats supported by MediaFlyer, as well as its number of preloaded apps for taking advantage of content feeds from YouTube®, Flickr®, Picasa®, and other external sites. The video also explains the role of the player (the only hardware required for the system) and shows how the system operates, walking you through its easy-to-use, Web-based interface for loading content, creating layouts, and populating layout zones with content. He then demonstrates how simple it is to assign content for display using the system’s schedule editor function. collapse
Video...iCOMPEL™ How-To (Part 7): Set up a publisher and subscriber.
This video covers setup of the iCOMPEL™ publisher and subscriber units. It begins with an explanation of the function performed by each and discusses what is needed to display unique... more/see it nowcontent on different screens. Next, it shows how to set up a digital signage channel, as well as how to use the iCOMPEL software interface to choose a publishing mode (manual vs. automatic), select a channel server (using the iCOMPEL unit’s channel folder, a USB flash memory folder, or an FTP site), and more. In addition, it explains how to connect a Web browser to a subscriber and how to set up the subscriber so it ”knows” where to pull content from. collapse
