Kramer White Paper Guide to Wireless AV Connectivity

Kramer’s latest White Paper provides a comprehensive look at devices for connecting HD video and audio over high-bandwidth wireless connections, and details the current and pending “white space” spectrum allocations for wireless AV connectivity in North America. The paper also explores the challenges of reliable transmission and reception of high bitrate HDMI and HD-SDI signals over 5 GHz and 60 GHz wireless links, including a discussion of both forward error correction (FEC) and techniques for multipath and echo compensation.

Several wireless systems are compared and contrasted and include 802.11n/a/an/ad Wi-Fi, Wireless High Definition Interface (WHDI), and Wireless High Definition (WiHD). Practical examples of each system are cited, along with their transmitting range and resistance to interference from co-channel and adjacent channel wireless devices. The paper concludes with a general discussion of design and operating parameters for wireless AV systems, including best practices.

Kramer’s Newest ProScale™ Digital Scaler/Switchers Have Built-In Mass Notification & Emergency Communication System

Kramer Electronics is pleased to announce that its newest line of ProScale™ digital scaler/switchers, the VP-770, VP-771, VP-773, VP-774, VP-773AMP and VP-774AMP are all equipped with a unique built-in Mass Notification & Emergency Communication (MNEC) feature.

This essential feature provides the ability to have an education facility, corporate campus, or stadium-wide emergency notification immediately displayed on connected projection screens and monitors. When connected to a network, the Kramer ProScale digital scaler/switchers can be set up to automatically display an alert message. Notifications include flexible options such as the inclusion of an audio alert siren, and the choice of displaying either a text crawler or a text window. The system can even have the Kramer ProScale digital scaler/switchers power up displays that are off in order to display these important messages.

Messages with “Extreme” and “Severe” headers appear nearly full screen and cover any other content. Messages with lower levels of severity appear as text crawls along the bottom of the image. The new Kramer line of presentation switchers only requires an ethernet connection to the appropriate campus network.

Emergency alert messages are composed and transmitted using the XML-based Common Alert Protocol (CAP) application. This allows a warning message to be consistently disseminated simultaneously over many warning systems to multiple proprietary applications and devices. These CAP alerts can include specifics about weather (hurricanes, flooding, storms, etc.), safety and security, as well as secondary functions, such as alert tones, horns, buzzers, and sirens.

The system complies with the official national warning system standard in the United States, the Emergency Alert System (EAS), which works in coordination with the Federal Emergency Management Agency (FEMA) and a number of US national emergency agencies.

Kramer Introduces the PT-1C EDID Processor


Kramer Electronics, a worldwide supplier of innovative and reliable signal management products, is pleased to introduce the PT-1C EDID Processor.

The PT-1C draws its power from the HDMI cable and is housed in a compact Kramer Pico-Tools™ enclosure. The key to its versatility are the four DIP-switches located on the back panel.

Many installers have experienced problems with the way Apple handles HDCP, especially when integrating Video Conferencing systems. One of the DIP-switches on the PT-1C turns HDCP on or off. When placed immediately downstream from a Mac with the HDCP off, the Mac outputs a non-encrypted signal that solves these issues with Apple’s implementation of HDCP. The PT-1C does not bypass HDCP rules and cannot remove HDCP from a signal if it is present.

Another DIP-switch on the PT-1C limits color depth. In situations where bandwidth on certain legacy equipment does not support Deep Color, the PT-1C can be used to ensure that only 8-bit color is passed.

The audio DIP-switch provides a means for limiting the output of an upstream device to 2-channel LPCM (Linear Pulse Code Modulation) for cases where the target EDID is asking for an audio type that other system devices do not support.

Finally, the EDID lock switch allows the user to lock in the EDID from the connected display or other displays/EDID sources.

The PT-1C is in stock and available from Kramer sales offices around the world.
