Toslink And Its Physical Attributes

without comments

Toslink is an optical fiber connection which is mostly for a consumer audio equipment which will carry digitalized audio streams between the parts such as the CD Players and the MiniDisc. It usually uses inexpensive 1 mm plastic optical fiber which may allow low cost production. It is much more popular than the “copper-based cabling”, since the hip surrounding the newer fiber technology. This fiber was created by Toshiba to connect their CD players to their radio receivers. But recently, it was found that the same function is present on all the CD players, irrespective of the manufacturer. To retain, some amount of originality, Toshiba’s mechanics are employed to send digital audio stream to MiniDisc recorders.

There are several apects about Toslink which may be confusing for potential customers. There are some points that are listed below which will help resolve all the confusions about this particular brand. Some of those points are listed as below:

Toslink is actually Toshiba-Link- It is the brainchild and registered trademark of the Japanese electronic company, Toshiba. Although Toslink is Toshiba-Link, its generic name is EIAJ optical

Is used for audio equipment- The usual users of this optical cable are pieces of equipment that carry a digital audio streams between components. The audio cable may support different physical standards and media formats. To reduce the electrical noise, this cable was introduced to reduce that.

Is a fiber connection system- the cable is made of either high or inexpensive quality fiber. It may use 1 mm of inexpensive plastic fiber or use expensive, multiple strands of plastic fibers. The usual length of the fiber is limited to a length of 5 meters. In the absence of a signal booster, the transmission can go upto 10 meters.

Is made up of four components- The cable is composed of the transmission module, the optical fiber cable, the optical connectors and the receiving module. The transmission module turns electrical signals into optical signals. The optical fiber cable is the physical transmission line. The optical connector connects the transmission module and the receiving module. The receiving module converts the optical signals back into electrical signals.

Connect a Toslink cable to a Mini-Toslink jack- A mini-Toslink jack may look like a 3.5 mm stereo mini-jack but thats where the similarity ends. The jack is 0.5 mm longer and the tip has a finger connection. It is common amongst Apple computers and minidisc players.

The bandwidth and application have a lot to do with what the cable is made out of. At times, it can be made of quartz glass optical fibers but as mentioned they can usually be made of either very expensive or cheap fibers. Although the old wires could run upto a mere 5 or 10 meter, the newer cables are capable of running upto 100 feet or more. The audio signal from a cable was limited to 48 Khz at 20 bits, but now has been increased to support modern formats. There are a few exceptions, however. They are DTS HD audio streams, Dolby Digital Plus and TrueHD.

Various Features to FLAC Player

without comments

FLAC Player or Free Lossless Audio Codec is an audio format through which one can listen to audio files. It is identical to MP3, but it is lossless; which means that the audio is packed in FLAC but has no loss in quality. The working is similar to ZIP, but one can be guaranteed a better sound quality. FLAC files can be played in one’s player similar to an MP3 file. The reason why this format stands out is because, in the world of lossless audio codec, its the best. It also has an open source reference usage and a decently documented format.

There are various features to FLAC player which make it one of the most sought after formats. Some of them are listed as follows:

1)FLAC is not very regular in favor of decode speed. Decoding is mostly required by integer arithmetic and is not too computer intense.

2)The encoding of audio data usually does not incur the loss of knowledge and the decoding audio is completely identical to the data that enters the encoder. The integrity of the audio data is further insured by putting the MD5 signature in the file header.

3)It has an amazing framing which limit the damage by stream errors, which limit it to the frame in which the error occured. It is usually a small fraction of a second worth of data.

4)It supports fast sample precise seeking. This helps in playback and helps in editing applications

There are certain steps that are used in playing these players. The materials or equipment that one may need is a computer, web browser, multimedia player and the internet connection. Those steps are listed as below:

1)The most commonly used players to play these files are a Mac OS, Microsoft Windows Operating System or Linux. The VLC player needs to be downloaded for this purpose. And the correct version of the player too.

2)After the download has been completed, one needs to double-click on the installation and the prompts are followed. Next, the audio file can be opened by choosing the option of ‘Media’ and clicking on the ‘Open File’ option.

3)The Foobar application which can be used as an alternative and directly supports the playback of the files. The Foobar application allows the player to convert nd save the file in another format.

4)For people inclined towards Microsoft Media Player Classic, the playback of this file is made possible with plug-ins module download that interpret the tags of the format.

5)One can finish the download by checking on the accept agreement and click on the ‘Next’ button. The player is then easily read by the Media Player Classic.

6)The filter module will allow MWMP to play back the file.

7)After downloading the plug ins, they need to be configured to the WMP to utilize the plugs.

Well, majority of the download is complete. Now all one needs to do is set back and enjoy as the music flows. FLAC Player is a great addition to any computer for a great listening experience!

All About Video Camera Camcorders

without comments

Video camera camcorder is actually a misnomer, because video cameras and camcorders all pertain to just one product, a camera that is able to shoot both still photos and motion pictures.

Thus said, we can say that it can be called either as a video camera or a camcorder. The term camcorder is shorthand for the words camera and recorder, since to be able to shoot videos, one should push on the record button, which is typically the red one on the body of the camera.

Video camera recorders are largely used by people from the television and movie industry, but is also used by hobby photographers to be able to capture on tape their own experiences.

Some Tips When Using Video Camera/Camcorders

Always remember that while video camera recorders are typically made to be able to withstand certain wear and tear conditions, they still are gadgets which could be damaged upon impact. So, take care of video camera recorders especially during times of commotion.

It will also help to be reminded, if one is a cameraman of a TV station, that the video is what matters, so in times of commotion, keep the tape rolling. Make a maintenance check of video cameras at least once a week to ensure picture quality. Clean the tape reel areas, and oil the parts that need oiling. Clean also the lenses to make sure that pictures stay clear.

An Introduction About Sniper Scope

without comments

Telescopic sight is often called a scope. Usually this technology is applicable in sniper rifles resulting in the name sniper scope. It is an optical device used to give elevated levels of accuracy using a point of aim for firearms, airguns and crossbows. Other sighting systems include iron sights, reflex sights, and laser sights.

Up until the 1990s, military use of telescopic sights was limited to snipers because the optical components were expensive and extremely fragile. They had been used as early as the American Civil War on rifles, and even at earlier periods throughout history. The glass lenses are susceptible to breakage, and environmental conditions including condensation, precipitation, dirt, and mud which can affect the external lenses. The scope tube also causes the rifle to feel more bulky. Snipers chiefly used moderate to high magnification scopes with specific reticles that allow them to estimate the distance from the shooting point to the target.

Telescopic sights are sometimes not advantageous to the user because of its tactical limitations. Snipers require stealth and concealment to get near enough to their target. A telescopic sight can prevent this because sunlight may inevitably reflect from the lens and a sniper raising his head to utilize a telescopic sight might actually expose his position. The famous Finnish sniper Simo Häyhä relied heavily on iron sights rather than telescopic sights to eliminate some of these concerns. Harsh climate can also be a great problem for telescopic sights as they are less weather resistant than iron sights. Many Finnish snipers in WWII prefered to use iron sights mainly because telescopic sights did not handle the very cold Finnish winters well enough.

The market for military telescopic sights made for military long-range shooting is extremely competitive. Many high end optics manufacturers are perpetually adapting and enhancing their telescopic sights to meet the demands of military organizations. Two leading European companies in this field are Schmidt & Bender and Zeiss/Hensoldt. American companies that have made their mark in this area are Nightforce, U.S. Optics Inc. and Premier Reticles. These more costly sighting parts usually cost € 1500 / $ 2000 and above. Chief options for military telescopic sights are reticule illumination that may be utilized in less than adequate lighting conditions and those that are inclusive of scope settings or ballistic relevant environmental measurements data that largely benefit the operator.

Nowadays numerous militaries issue telescopic sights to their infantry, typically compact, low-magnification sights appropriate for snap-shooting, like reflex sights. The US military issues ACOG, Aimpoint CompM2 and EOTech 553 combat optics. American soldiers in Iraq and Afghanistan generally purchase their own combat optics. The British army uses the SA80 rifle with the SUSAT 4× optical sight as standard issue. The Canadian Forces standard C7 rifle has a 3.4 Elcan C79 optical sight. Both Austria and Australia use different forms of the Austrian Steyr AUG which has built an integral 1.5x optical sight since its issue in the late 1970s.
