How HDMI is Changing the AV Industry

Reading Time: 2 minutes

There is no question that the hottest technology in the AV (audio/video) market today is High Definition Multimedia Interface (HDMI), as it has made it possible to not just combine the PC and AV, but also provide unprecedented advances in digital entertainment.

Jointly developed by Panasonic, Sony, Philips, Hitachi, Silicon Image and Thomson and Toshiba, HDMI has been the driving force behind the Blu-Ray movie players, HD-DVD, high definition TVs (HDTV) and other AV products.

Defining HDMI

HDMI is a cable and plug in device that allows for the delivery of high definition video resolutions and also multiple audio channels.

The HDMI itself is a cable that contains 19 wires inside, which allows for the delivery of 5 Gbps of uncompressed digital audio/video, a bandwidth previously unheard of.

How it Works

The HDMI wires function by emitting digital signals from an AV source, be it an A/V receiver, DVD player, or satellite receiver. It then relays the signal back to another digital device (i.e, a HD camcorder). Despite the high quality of the audio/video, HDMI actually utilizes less than 50% of its bandwidth.

All HDMI wires have 192 khz, 24 bit 8 channels, which allows for transmission of uncompressed audio. However, it also has support for compressed ones, like Dolby and DTS.

Features

Aside from delivering the highest quality AV possible, HDMI also has the capacity to serve up high quality video, from 720p, 1080I and 1080p. Stereo support and multi channel, surround sound are also part of the package. Moreover, it is not limited to definition formats like NTSC, but also allows for formats like PAL and 480p.

There is also an auto lip sync function built in, which permits an HD device (compatible with HDMI 1.3 or higher) to properly align out of sync AV.

HDMI are classified into two: Type A and Type B. Type A is the standard 19 pin cable and is suited for TV, computers, and other HD consumer products. Type B has 29 pins and is geared towards cinemas.

HDMI Advantages and Benefits

The best way to determine the advantage of having an HDMI enabled device is to just look and/or listen to it. Because HDMI is all digital, the data that is delivered is vastly superior to analog devices. Unlike analog cables, there is no compression, so there is no loss of visual or audio detail. Also, unlike other digital interfaces, there is no digital to analog conversion going on, a process that can lead to a deterioration in the data.
Versions

Because it has more bandwidth than it actually uses, progress and innovation of HDMI is made easier. The earliest release HDMI 1.0 came out in 2002 and supported 3.96 Gbps for video and 8 channel LPCM/192 kHz/24-bit for audio. The subsequent releases and updates have added support for One Bit Audio, Deep Color (30bit to 48 bit), Dolby TrueHD and many more.

The biggest advantage of HDMI, cost wise is that with a single HDMI cable, it renders obsolete the need for 3 video connections that used to be needed for HD. In the case of HD audio, six connections were previously needed.

Based on the surveys, over 140 million HDMI devices were sold in 2007 alone, and it is widely expected that the number will increase even more in the upcoming years as prices drop and technological innovations continue.

Using Bluetooth

The amazing technology of Bluetooth presents a great way of exchanging data between two wireless devices. Unlike telephones, there are no wires or messy leads to worry about.  You can enjoy wireless communications with short distances of up to thirty feet.

Bluetooth also offers interoperability, meaning that you can use your portable Bluetooth device to connect with existing Bluetooth points.  This way, you won’t have to carry a data lead or CDs of drivers around with you everywhere you go.  You can enjoy the best of wireless without having to worry about installing your software.

With today’s Bluetooth, you can use your PDA and cell phone to surf the net or check emails as you travel. If you are in the business field, this can be very beneficial, especially if you like to check your email throughout the day.  Bluetooth will enable you to check your email no matter where you are – which is great news for those who like to travel.

Bluetooth will also enable to you to transfer files as well, such as MP3 and photo to and from your mobile device.  Bluetooth dominates the world of short range wireless, enabling you to do more than you may have thought possible.

One of the best things to Bluetooth and something everyone loves is the wireless headset.  Bluetooth offers wire free headsets for your cell phone or computer, which is great for those who like to walk around or talk on the phone in the car, without having to worry about your hands getting in the way.

To make things even better, you can use a Bluetooth GPS device for satellite navigation on your PDA, laptop, or mobile.  If you travel – this can be really great to have.

Cooling Your Hard Drive

Reading Time: 2 minutes

For several different reasons, storage is a very important part of a computer. These days, computers do far more than they ever have in the past. From businesses to family photo’s, storage is the ideal way to keep documents on your computer. The most popular method of storage is the hard disk drive, which we all count on for keeping our data safe.

Even though the hard drive stores data, it isn’t perfect by any means. Hard drive failure is very common with all computers, with no real way to prevent it. Although there are several different reasons why a hard drive can fail, the most common is overheating. Viruses and crashes are common as well, along with theft and accidental deletion.

With the older style and mechanics of hard drives, the RPM speed was low, meaning that the drives wouldn’t overheat. The hard drives we use now days, have speeds between 7,200 and 10,000 RPM, meaning that they can get quite hot when they start working. Computers of this day and age come with fans to cool everything down, with most hard drives including temperature sensors as well, so you can keep track of just how hot your hard drive becomes.

With hard drives today, overheating is a very common problem. The faster hard drives come with speeds of 10,000 RPM, which can make the temperature soar above 70 degrees F, really heating things up inside the drive. The mechanics on the inside are built to withstand the heat, although if things become too hot, you’ll encounter problems. If a drive becomes too hot and ends up losing the data, it may be next to impossible to retrieve the information – no matter how good your data recovery specialists may be.

One area that suffers from the drive overheating is the platters, which are magnetic media. Platters are what carry the data throughout the hard drive. Platters are constructed from optical glass, aluminum, or ceramic and normally coated with a layer of magnetic material. Once the hard drive begins to heat up, the platters will start to expand, which changes their size. When this happens, the magnetic surface on the platters will get destroyed, which results in a loss of data. If the physical area of the platters are damaged, it will result in unreadable sectors.

Other areas of the hard drive that can be damaged due to overheating are the read and write heads, head actuator, and the controller chip. Hard drives are very sophisticated pieces of hardware, and can’t handle overheating. The read and write heads are a common example, as they can easily render the drive useless if they become damaged. If they get too hot, they don’t make any contact with media, which pretty much stops the flow of transfer from information to the computer.

To prevent your hard drive from overheating, you should always make sure that it is cooled properly and well ventilated. You can always get additional fans and coolers, which will improve both ventilation and the flow of air in your computer. You can buy fans and coolers at very affordable prices, which makes them an ideal investment for keeping your hard drive or hard drives cool.

You can also get software that monitors the temperature of your hard drive as well. Whether it’s software, or additional fans, you should always ensure that your hard drives are kept cool. By keeping them cool, you’ll greatly reduce the amount of crashes. You’ll also increase the stability of your hard drive as well, which will make your entire computer perform much better.
