HDBaseT in HDMI Extenders Over Cat5e/6/7 Cable

The main drawback of HDMI as an A/V connection standard, when it comes to high definition video distribution, is cable length limitation. Installation costs quickly add up when you consider HDMI cables, control cables and HDMI repeaters for solving distance limitation. To cope with this limitation, a multitude of HDMI extenders over standard cat5e/6 cable became available – each of them providing proprietary solutions to support HDMI extension along with different control signals including CEC, IR, RS232, USB. The downside in all these implementations is that 150 feet proved to be the maximum distance for 1080p/24bit/60Hz resolution, with full HD support guaranteed well under 100 feet. With growing popularity of 3D formats, the need for a new technology became apparent.

HDBaseT is a new connectivity technology optimized for home and commercial multimedia distribution promoted by HDBaseT Alliance. The cornerstone of HDBaseT technology is the “5Play” feature, which means transmitting full uncompressed high definition video, audio, 100BaseT Ethernet, power, and various control signals through a single standard 100m/328ft Cat5e/6 solid cable. HDCP is also handled by the technology.

HDBaseT supports TV and computer video formats including standard, enhanced, high definition and 3D video, as well as all audio standards. HDBaseT delivers full HD/3D and 2K/4K uncompressed video in a point to point connection or a single to multipoint distribution supporting both daisy chain and star topologies. When cascading, extension limits can go beyond 100m/328ft – up to eight additional 100m/328ft runs can be combined. This flexibility makes HDBaseT an ideal commercial technology for applications such as digital signage.

HDBaseT supports 100Mb Ethernet, enabling televisions, hi-fi equipment, computers and other devices to communicate to each other and to access stored multimedia content. Different types of control signals are also supported by HDBaseT technology, starting from Consumer Electronic Control (CEC) that operates basic functionality such as power-on, power-off play and stop, to RS232, USB and infrared (IR) that operate remote equipment even when located in a different room. This large variety of control signals gives equipment manufacturers and integrators the flexibility to choose the solution that best meets their needs.

The latest addition to the HDBaseT 1.0 specification is Power over HDBaseT or PoH. This enables the transfer of DC power, along with data signals, over a single Ethernet cable in a manner similar to Power over Ethernet (PoE). PoH safely delivers up to 100W over four pairs of Ethernet cable, which allows power to be supplied to the attached devices through the cable, requiring no additional power supplies. The latest Energy Star 5.3 Specification restricts all TVs to 108W of power consumption, regardless of screen size. Energy Star 6.0 Specification targets a cap of 85W for all TVs. At these levels, HDBaseT has ample power delivery capabilities for supporting even large displays.

Network Technologies Inc (NTI) integrates the HDBaseT technology into its new line of HDMI extenders. The ST-C6HDMI-HDBT extender supports full HD/3D extension to 328ft, HDCP, CEC, IR and optionally SPDIF. The ST-C6USBHE-HDBT supports all of the features listed for ST-C6HDMI-HDBT, plus 100BaseT Ethernet, RS232, and USB support for USB keyboard/mouse and an additional USB device, such as a USB touch screen monitor, USB CAC card reader or USB whiteboard. Both extender models require only one power supply to power the local and remote units, which can be attached at either end. SPDIF audio and USB are not standardized in HDBaseT technology; therefore NTI employs proprietary solutions in its extenders. The way power is delivered through the Ethernet cable is also a proprietary approach tailored to extender applications and provides flexibility at a lower cost.

Battery Comparisons for Blackberry, Android, Apple and Windows Smartphones

You make a plan to meet up with your friends to show off the latest and greatest smartphone that you’ve just spent a small fortune on. Taking it out for all to view, you hit the power button. Nothing. In a mere few hours since buying the mobile device, the operating system used on the smartphone has drained it dry. To avoid this unfortunate situation, compare the iPhone battery to the Windows, Android and Blackberry batteries.

iPhone Battery Comparisons Apple has made it one of their goals to produce devices with extended battery life times. The iPhone battery life has some of the longest talk times currently on the market. The Apple iPhone 4 has talk times between seven and fourteen hours depending on whether the 3G is turned on. This was an improvement over the iPhone 3 battery with average talk times between five and eight hours. However, the iPhone 4S has an average of six hours of talk time. It is potentially caused by the iOS 5 included on the device. Apple is expected to offer an update to correct this problem.

And the Rest… Windows 7 phones use a single core processor which can reduce the drain on the battery life. The Samsung Focus S uses the Windows 7 operating system and users have been able to get as much as twelve hours of heavy usage out of the device before the battery has drained. The Blackberry battery life for the Bold 9780 is six hours of talk time and four hours of talk time on the Bold 9000. The Blackberry Torch battery has almost seven hours of talk time available. Although HTC devices have received some backlash, many of the Android devices from Samsung, Motorola and LG have talk time averages of eight hours or more.

Considerations It is important to remember that battery power differs from device to device. For instance, numerous consumer complaints arose in regards to the HTC EVO battery. Reports came in that the Android device would not last throughout the entire day without the need to be recharged. Although this Android phone has poor battery power, other phones with Android are well-renowned for lasting hours upon hours. For instance, the Samsung Epic Touch has an Android-based OS and lasts for an impressive seven hours and twenty-two minutes of talk time.

Battery Life Tips Want to make your iPhone, Samsung or Nokia battery last longer? Check out whether or not you are on your phone carrier’s 3G or 4G networks. Disabling this feature has the ability to more than double talk times on most smartphones. Also, Android phones are also set for the brightness to be displayed at the maximum levels and lagging times for sleep modes. Change these settings to increase standby and talk times for your Motorola Droid X Battery and LG Optimus and Samsung Galaxy batteries that rely on Android before use operating systems.

Solar Energy – The Futuristic Source of Energy

Almost all the non-renewable sources of energy are progressing towards a state of exhaustion. If we do not harness the power of the renewable sources to their maximum potential, we may face severe consequences in the future. This is why it has become essential to identify and explore the renewable sources of energy, such as solar energy. The sun is probably the biggest reason behind the existence of our planet.

However, there are certain challenges associated with harnessing solar power in an optimal fashion. For instance, the following three questions arise when you first think about utilizing solar power:

• Earth receives only a minuscule amount of sun’s energy. How can the heat reception and utilization at our planet be maximized?

• We receive the solar radiations only during the day. How can we make up for the energy to last through the night?

• Even after all the evolutions in technology to harness solar power, we can still only manage to use the energy falling on a given surface. How can we concentrate all this energy at one specific spot?

All these questions compel us to think about the future of solar power. Many researchers have predicted that solar energy is the energy of future, and will soon be available as a fully competitive energy source along with the present sources.

Solar Energy Today

In the current scenario, solar electricity is mainly generated using solar panels or photovoltaic (PV) cells in a home solar system. In a home solar system, solar panels simply convert sunlight into electricity, which is then supplied further. The main drawbacks associated with the solar panels of the past were the efficiency and the absence of power in the night. However, recent developments in solar panels have resulted in increased efficiency of the solar panels as well as made it possible to produce limited amounts of electricity even during the night.

Solar Energy Future

Solar panels are now globally used in the home-based solar systems as well as for commercial purposes. One of the main reasons for growing popularity of home solar systems is the guarantee that comes with the solar panels. These solar panels guarantee to offer you the continuous power supply for 25 years. Also, the government incentive schemes run by several state government become a motivating factor behind using solar power.

It may still take a while until we can completely depend on solar energy for our power requirements. However, with the present rate of fossil fuel consumption, more and more people are turning towards the sun as the ultimate source of energy.
