Wireless speaker for Windows® launched

Oregon-based Aperion Audio has announced the launch of a wireless speaker that allows Windows-using music fans to listen to their favorite track from anywhere where there is a home network connection.

How it functions?

Named ARIS wireless speaker, the unit is developed to work with Windows 7’s ‘Play To’ feature that makes it easy to stream content from a PC over a home network. ARIS uses the DLNA (Digital Living Network Alliance) protocol, which is supported on many new HDTVs and Blu-ray players. Once connected to a home network via Ethernet or Wi-Fi, the unit will show up as a device on a networked PC running Windows 7 or Windows 8 Consumer Preview.

Featuring a single-piece brushed aluminum enclosure, the ARIS measures 6.5 inches high, 6.5 inches deep, and 14.75 inches wide, and weighs in at 11.3 lbs. The ARIS wireless speaker for Windows is priced at US $499 and is scheduled to ship mid-June 2012. Pre-orders are presently being taken on the company website.

Microsoft® to use Dolby Digital® Technology in Windows® 8 PCs and tablets

Software giant Microsoft Corporation has announced that it will incorporate Dolby Laboratories sound technology in its upcoming operating system Windows 8-based PCs and tablets.

Windows 8 will support the playback of Dolby-encoded files, with the firm saying that it will offer out-of-the-box support. According to Microsoft, Dolby Digital Plus will be supported on all versions of Windows 8 including the ARM architecture.

Benefits of Dolby Digital Technology

“With the incredible growth of online download and streaming media, particularly for video content, this agreement ensures a great audio experience for those consumers who wish to download or stream TV and movies containing Dolby Digital Plus. Additionally, all of their existing and future home videos recorded with Dolby Digital Plus audio will work great on Windows 8 right out of the box,” said Tami Reller, CFO and CMO of Windows and Windows Live at Microsoft.

The collaboration ensures the presence of Dolby Digital format on Windows ecosystem beyond Blu-ray or DVD, and creates the opportunity to bring a differentiated audio experience to Windows 8-based PCs and tablets. What should be noted here is that PC makers will be forced to pay for Dolby Digital support.

How to Troubleshoot Audio Problems in Windows 7

Some of the users of the Windows 7 operating system see a red X in the notification area over the icon of the speakers even when their output is working in the right manner. They are able to hear the sound from their computer systems but still see a red X mark in the notification area. Think of the case when you have finished installing or upgrading to the new operating system launched by Microsoft i.e. the Windows 7 and in the notification area of the system tray you see a red ‘X’ over the icon of the speakers which shows that the audio output is not functioning in the correct manner.

This would be an indication which would tell the users that their audio output is not functioning. Additionally when the users would move their mouse over the icon of the speakers then they would also see a tool tip which would indicate that the audio service of the system on which the users are working is not functioning in the correct manner and they need to fix the problem if they wish to hear any sound from their system. In the actual manner, the audio service works fine and runs in the correct manner. Also the playback sound works in the right and correct way. There seems to be no problem when you hear the sounds from these systems except from the fact that you would see a red X on the screen of your computer which would make you think as if something is wrong with your audio output.

Cause of the Problem

This kind of problem can be due to the heavy disk activity when you are booting to the Windows desktop. In this type of situation even when the windows audio service has started the status of the speaker icon in the notification area would still show a red mark which would indicate that the audio service is not yet available but actually the playback would be completely functional at that time.

Solution to the Problem

If you are going through this sort of situation then you should look for the ways through which you can get rid of this situation. In many of the cases it has been observed that this red sign is temporary and it goes away when the Windows 7 operating system ends up booting to the desktop and also when the activity of the hard drive is decreased considerably. It can also disappear when the user clicks for the first time on the icon of the speaker when he wishes to change to the volume level of the audio playback. This type of behavior of the system is actually cosmetic and it does not create slowing down of the system or does not affect the performance or the speed of the system.

More Information about the Topic

If you wish to know that where you are going to experience this kind of situation then the answer to this is that it can be encountered when the setup of the Windows 7 and OOBE has finished and when the user restarts the computer to the Windows desktop. At this time, the system would be having a very heavy disk activity as the setup would finish all of the pending and final tasks. Also, the startup applications would be initialized and this causes a heavy activity of the disk.

Advanced Technology at the Palm of Your Hands

We all have been waiting for a long time for a new portable, efficient projector to be available in the market. It’s been a hard time to carry heavy projectors during our business presentations, school lectures, and classroom reports.

We don’t have to worry any more because Samsung, one of the well known media providers in the world, has already released their first ever Pico projector that is within our palms’ reach.

Yes, you read it right. Here are the facts:

  1. The new Samsung SP-HO3 Palm-Sized Pico Projector is the new innovative gadget Samsung created to fit on our palms.
  2. The Samsung SP-HO3 Palm-Sized Pico Projector is a standard projector like what business men, educators, and students use for their presentations and reports. But the Samsung SP-HO3 Palm-Sized Pico Projector has so much more features like built in programs and playback features than our old projectors have.
  3. The palm-sized projector weighs 170 in grams and has a dimension of 63.5mm x 38mm x 63.5mm. We can easily store or place the projector in our pockets, briefcases, bags, or purses.
  4. It contains 30 lumens which allow us to view images with 9-80 inches in size. It also uses an advanced LED technology as it has energy efficient LED light (which are eco-friendly, by the way) that can work for 30,000 hours.
  5. It is also capable of playing WVGA videos which are 854×480 in size. We don’t even have to worry about the large files we need to present because it comes with a separate 1GB internal microSD memory card.
  6. The Samsung SP-HO3 Palm-Sized Pico Projector has a USB port which comes with a built in feature to instantly playback videos, audio, and image files during presentation.

It also has built in document and video viewers for Microsoft Office Suite, such as:

  • MS Word,
  • MS PowerPoint,
  • MS Excel,
  • Adobe,
  • PDF,
  • movie,
  • audio, and
  • image files

These are the applications or files which are usually used during presentations. The projector also has a built in MP3 Player for easy access of music playback.

The best thing about this Pico projector is that it remains affordable even with the many features it has. So this is still accessible and readily available for educators and students who really need to use one during their lectures and reports. With the new Samsung SP-HO3 Palm-Sized Pico Projector, we can say that big things truly come in small packages.

The device’s 1GB worth of memory space entices users to purchase it as, surely, it is able to load any media content directly to the device. One of the features that its owners love is the built-in multimedia playback feature that is seamless, meaning, it does not have to be tethered to any computer in order to share music, images, documents, or videos. Once again, the Samsung SP-HO3 Palm-Sized Pico Projector is Samsung at its finest.

How PCI Works

One cannot imagine working without computers, as we end up doing a number of things with their help.  Many types of communication like text, audio and video are  made using computers. The industry of computers is progressing day by day and new devices and components are being introduced. These devices are compatible with computers because of the buses (data transport systems) which transport the data from a component or device to CPU and vice versa. There are two main types of buses

System Bus

It is used to transport data between system memory and CPU and transport the data at much faster speed than any other Bus including PCI.


PCI bus is comparatively slower than system bus and it is used for connecting hardware devices like modems, sound devices, graphic devices and hard disks to the computer. It is connected to CPU via Bus Bridge which connects PCI devices and ISA devices to the CPU.\

PCI refers to Peripheral Component Interconnect. The work on PCI started in 1990 at Intel’s Architecture Development Lab. PCI were not put into every computer just after they were introduced but it took more than 4 years to make a significant mark and replace other buses like ISA and VESA Local Bus. The fact was that Microsoft introduced Windows 95 which supported a new feature called Plug and Play (PnP) and this boosted up the demand of PCI by great value. PnP is basically a core utility of BIOS. A PCI-based hardware is just inserted and the PnP feature itself recognizes the hardware, installs it and makes it ready to use.

There are some other buses like universal serial bus(USB) which are quite different from these two in function, as they connect devices like phones, cameras, printers and scanners with the computer.

How PCI works

PCI works in a very simple yet managed manner to transport the data to CPU. PCI devices are connected to the PCI bus which is connected to the Bus Bridge which is further connected to the CPU. It is connected in the following manner:

PCI device   > PCI bus   > Bus Bridge   > System Bus   > CPU.

This is the way a PCI device or hardware is connected to the CPU. ISA devices can also be connected to the CPU via Bus Bridge which is further connected to the PCI bus and so on.

PCI devices are very simple to install because of the Plug and Play feature. You just have to insert a PCI-based hardware in any of the empty PCI slot and the CPU will itself detect and install the driver.


Some specifications of PCI are:

  • PCI cards usually have 47 pins (except mastering cards which have 49 pins)
  • PCI is based on the Plug and Play feature which makes adding hardware easy.
  • PCI cards are operated at two voltages: 3.3 volts and 5 volts.
  • PCI cards are of two bandwidths: 32-bit and 64-bit.
  • PCI bus speed ranges from 33MHz to 133MHz.
  • PCI data transfer speed is from 132 Mbps to 1 Gbps.

Future of PCI

A lot of people think that PCI bus cannot be replaced but some computer experts have the opinion that as PCI replaced ISA, some new bus system will also replace it in near future. They say that PCI has approximately reached the upper limit of its capacity and would soon be replaced by any other Bus system.


There was a time when Napster and Gnutella were used for file sharing but then came Kazaa. Formerly capitalized as KaZaA. The plus point for Kazaa is that it not only allows its user to share simple files but also videos, television shows, and many other types of digital information. And because of its worthy features, it soon became popular among millions of people as one of the largest file sharing site. But it had to face the same problem as Napster had to face, because many film industries started criticizing it because of its unlimited video sharing feature.

Main idea

Kazaa is a decentralized Internet peer-to-peer file-sharing program owned by Sharman Networks, developed in March 2001 by programmers Niklas Zennström and Janus Friis of the Dutch company Consumer Empowerment. It is a file sharing program, which allows you to download audio, video, images, documents and software files. Kazaa has had problems with people contacting viruses from their software but Kazaa are trying to sort the problem out. Unlike the file-sharing program Napster, this used a centralized server to index files, Kaaza users share files directly from each other’s hard drives. A computer’s owner can decide during Kazaa setup which files on their computer will be available for sharing.

Working Criteria

When a user wants to find files, the user’s ON sends a query with keywords over the TCP connection to its SN. For each match in its database, the SN returns the IP address and metadata corresponding to the match. Each SN also maintains long-lived TCP connections with other SNs, creating an overlay network among the SNs. When a SN receives a query, it may forward the query to one or more of the SNs to which it is connected. A given query will in general visit a small subset of the SNs, and hence will obtain the metadata information of a small subset of all the ONs.The peer-to-peer searches occur through users with fast connections, called Supernodes. Once located, the file is sourced for downloading directly from the user who has it. When a user installs the Kazaa software on his or her computer, it comes coded with a list of supernodes. Every time the user launches the Kazaa application, his or her computer registers with the central server and then chooses from a list of currently active supernodes. When the computer sends out a request for files the user wants to download or upload, the request is funneled through the supernode. The supernode communicates with other supernodes, which in turn connect to regular nodes that in turn connect to even more regular nodes, to fulfill the request until the Time to Live of 7 runs out — this means that the search request will extend seven levels into the network before it stops propagating.


Kazaa is actually a legal program but because of the way it’s used, its developing company and several users have already been sued for copyright violation. Uploading or downloading works protected by copyright without the authority of the copyright owner is an infringement of the copyright owner’s exclusive rights of reproduction and/or distribution. Due to it being used primarily for this purpose, the creators of Kazaa have been sued for being a sort of “enabler” for piracy. Since 2008 there has been a new owner of Kazaa who made unlimited, unrestricted, and safe downloads at a monthly phone bill fee. But Kazaa has a lot of spyware in it which makes it use a bit unsafe.
