Pushing the Boundaries of HDR Video

  • PDF

Alan Chalmers

Researchers at WMG at the University of Warwick (UK), have found a way to compress and stream HDR video directly to monitors and mobile devices, such as an iPad.

The researchers, in partnership with University spinout goHDR, patented a method of real-time encoding and remote display of High Dynamic Range (HDR) video. With Portuguese partner INESC Tec, they also have been able to demonstrate their technique in action on an iPad.

This means HDR video content can now be encoded and streamed directly to remote displays, including mobile devices, or sent for storage back at home-base. Gaming could be transformed too, with HDR content available for interactive online and cloud-based games.

While HDR imagery delivers the wide range of light intensity levels found in real scenes ranging from direct sunlight to details of dark shade, the amount of data required to capture all of this extra detail is huge.


Streamit's New Generation of In-store Audio at ISE

  • PDF


Streamit will showcase their next generation of in-store audio receivers at ISE2013. The Lisa and Lisa LCD, says the company, are “more powerful and priced aggressively.” The Lisa is also a lot smaller.

Professional internet radio receivers, the Lisa series stream as well as store-and-forward. With configurability and easy remote management, the new product design for the Lisa allows Streamit to reduce the production costs resulting in improved price/performance for the in-store audio devices.

Lisa has a very compact design (width 9.8 cm x height 2.3 cm x depth 8.2 cm) and is compatible with older Streamit radios/technology

Samples of the Lisa series are available and the production models expected in Q1 of 2013.

Extron DSC 301 HD

Extron Electronics introduces the DSC 301 HD a compact HDCP-compliant video scaler. This scaler has an HDMI input, configurable high resolution analog and composite video inputs, and an HDMI output.

Featuring an advanced scaling engine with 30-bit processing and 1080i de-interlacing, the DSC 301 HD handles output resolutions up to 1920x1200, including 1080p and 2K. It includes EDID Minder, automatic input switching, and simplifies system connections by embedding audio from one of the three stereo inputs onto the HDMI output. Designed for professional integration, the compact, low profile half-rack width enclosure enables simple and discreet mounting in many environments.

"The DSC 301 HD delivers high performance and a wealth of features at an economical price point," says Casey Hall, VP Sales and Marketing for Extron. "With its compact form factor, and compelling feature set, this scaler lends itself to basic applications calling for a three input switching scaler as well as more complex systems where multiple scalers are deployed into a large signal distribution system."

  • PDF

Extender Plus

Extron's new Extender Plus VGA and audio line driver with EDID Minder is a one input, one buffered output line driver that extends VGA-QXGA and HDTV component video along with audio signals up to 75 meters (250 feet).

Unbalanced computer stereo audio is converted to balanced, line level stereo audio to eliminate noise usually associated with unbalanced audio when distributed over long cable runs. It features EDID Minder, which automatically manages EDID communication between connected devices to ensure that the source powers up properly and reliably outputs content for display.

The Extender Plus is available in Decora-style and AAP form factors, providing convenient AV access and signal extension for a wide variety of environments.

  • PDF


Extron Electronics announces immediate availability of the DTP HDMI 230 twisted pair extender for transmission of HDMI, audio, and bidirectional RS-232 and IR control signals up to 230 feet (70 meters) over a single CAT 5-type cable.

The HDCP-compliant extender provides an economical and effective means for extending HDMI with embedded multi-channel audio from HDMI-equipped devices. In addition, the DTP HDMI 230 accepts analog stereo audio signals and digitizes them for simultaneous transmission over the same single twisted pair cable. Designed for extending HDMI, audio, and bidirectional control in space-challenged environments, the DTP HDMI 230 features compact enclosure sizes and remote powering.

It allows a direct connection from devices with an analog stereo audio output, such as desktop computers or laptops, and provides balanced and unbalanced audio output from the receiver. In addition, the DTP HDMI 230 continuously maintains DDC communication of EDID and HDCP between a source and display for reliable operation, ensuring direct compatibility and optimal signal transmission between devices.

Delta DVCS

Delta Products launches the Super Resolution Image Software (SRIS) and IP Stream Software (IPSS) to its Distributive Vision Control System (DVCS) family.

Aimed at the fast-growing process-based industries such as electrical, water, oil, gas and data, the new SRIS can capture and display videos and images at resolutions up to an astonishing 102,400 x 7,680, all in real time with high performance. With the latest DVCS processors, you can display virtually any super high resolution image on virtually any number of screens.

Based on the DVCS technology, the new IPSS offers the abilities to capture and display all types of IP streaming signals. This enables the DVCS to participate in large-scale surveillance networks with high-performance decoding and monitoring capabilities.


VidaBox Debuts Power-Over-CAT5 Charging Solutions

  • PDF


VidaBox's vCharger draws constant voltage from a vPower station via CAT5 cable, and converts that voltage to charge a connected USB device, such as an Apple iPad, iPod, iPhone, Android device, Kindle Fire or Samsung Galaxy Tablet. The vCharger can be located as far as 100m (328 feet) away from the vPower, and still provide full charging power. Up to four vCharger units can be connected to a single vPower station by adding a vPower four-port adapter.

vCharger has no moving parts which promises long-term use. This mini 3"x2"x2" device can be easily hidden inside any in-wall/back boxes and function without ventilation; it is not rated for standalone, in-wall use.

For added flexibility, the vCharger is backwards compatible and can be used with older Power-over-Ethernet (PoE) switches as power sources.
