Portable DVD Players: Just the Basics About Headphones

Christine Peppler asked:


For anyone wanting to enjoy their portable DVD player outside of the privacy and solitude of their own room, headphones are a critical accessory. They allow the viewer to listen to movies and music without disturbing those nearby and often act to reduce environmental noise which can intrude on the audio experience. Both comfort and audio quality are important considerations when selecting earphones.

• For those who will be using their portable DVD player to entertain two viewers at a time it is important to assure that the device has 2 headphone ports on it; otherwise a splitter (Y-plug) will be needed.

• Various styles of headphones offer different advantages.

For anyone wanting small, inconspicuous devices any style of in-the-ear headphones can be a good choice. They are often the headphone of choice during activity, but in the case of use with a portable DVD player this is generally not a concern unless it is used for listening to music. Ear bud style headphones are often less comfortable and offer lower quality sound than in-the-canal type headphones. On the other hand, in-the-canal headphones generally require more frequent cleaning. Both require a good fit to offer the best quality sound.

Around-the-ear headphones with earcups can be quite secure and reduce the intrusion of outside sound without consuming additional battery power although they tend to be a bit more noticeable to the wearer than in-the-ear models.

Over the ear headphones help reduce the risk of hearing loss as the signal from in- the-ear devices is amplified by several dB. For comfort, padding over the earpieces and an adjustable headband is recommended. Some users feel that sound quality with over the ear headphones is superior and helps to reduce noise escaping which can disturb others. Some models even offer behind the neck or headband-less styles for added comfort which allows users to don a hat and avoid disturbing their hair. These types of headphones tend to be lighter but also more fragile.

Wireless headphones free the user from wires but have the drawback of using a great deal of battery power in conjunction with a portable DVD player which already consumes a great deal of energy. With wireless headphones, users are also given freedom to move about when listening to music via their player.

Noise canceling headphones are effective at eliminating environmental noise by creating an out-of-phase signal to cancel unwanted outside noise. As this is not a passive process, additional battery power is consumed to achieve this effect.

• A final, but important consideration in selecting headphones for a portable DVD player is to assure that it is compatible with the device. The cord on the earphones must obviously be capable of connecting to the player or an adapter will be needed, adding more weight and bulk where it is not wanted.



The Definitive Portable DVD Player Glossary, Every Feature Explained

Rose Li asked:


Like all electronic products, features for portable players are also full of jargon. As a reseller of portable DVD players it is important for you to understand these clearly for two reasons:

* Savvy consumers knows and understand electronics and are looking for an equally adept seller

* Novices need help understanding which product is right for them

Here is a list of terms which should help you go from zero knowledge to expert in no time:

** Disc Formats **

CD: Short for Compact Disc Read Only Memory (CD-ROM), is a pre-pressed compact disc that contains data accessible to, but not writable by, a computer.

CD-R: A CD-R (recordable) allows for content to be written once and read many times. This type of disc stores all types of media files.

CD-RW: This is a rewritable medium that allows for content to be written many times and read many times. The CD-RW can also be used to store different formats of content.

VCD: Also known as Video Compact Disc is a format for storing video on CDs, and is not dissimilar to a VCR in that you cannot skip chapters or view rich data, just fast forward and rewind.

SVCD: This stands for Super Video Compact Disk. This is a successor to the VCD and was meant to challenge the DVD format. Quality and storage capacity is superior to a VCD, but lower than the DVD.

DVD: Digital Versatile Disc or Digital Video Discs. They look like CDs but store six times more data and can display video in chapters.

DVD RW/ DVD+RW/ DVD-RW: These three terms essentially mean the same thing. These are rewritable DVDs. They can be rewritten close to a thousand times, making them very useful as backup media. The + and – and competing standards, though it is generally accepted that + is superior and therefore the industry standard for rewritable disks.

** Media Formats **

MPEG 1, 2, 3 & 4: These are compression standards for audio and video set by the Moving Pictures Export Group. The numerals refer to versions with MPEG 1 being the 1st and MPEG 4 being the latest. These standards apply across all transmission and distribution platforms.

MP4: This is another name of the MPEG 4-Part 14 standard created by the Moving Pictures Expert Group standards. This standard specifies compression for both video and audio. Commercially a number of manufacturers use MP4 on products that can playback both audio and video. However, this is misleading as MP4 products must be able to playback files with the extension .mp4.

WMA: Windows Media Audio is an audio data compression standard developed by Microsoft.

DiVX: This is a compression technique that converts lengthy video sequences into smaller parts without loosing too much detail. It uses the MPEG-4 compression standard.

XVID: The opposite of DiVX, is a compression technique and a direct competitor for DiVX. It also does video compression based on the MPEG-4 standard. The difference between the two is DiVX is proprietary while XVID is distributed under Gnu or is free to use.

MP3: Designed by the Moving Pictures Expert Group, this is a standard for audio files compression.

JPEG: This is a compression standard for photographs and is used by most digital cameras. Having this lets the user playback pictures from the camera on the portable DVD screen.

** External Ports **

AV In: Audio/Video input point to connect external devices like a video cam direct to the player

AV Out: Audio/Video output point for connecting DVD player to home TV, car system etc.

VGA Out: Video Graphics Array port, first introduced in computers now popular in portable devices, used to connect to LCD displays among others.

USB: Universal Serial Bus is one of the most common interface devices on a variety of platforms from computing to audio/video. With the USB you can hook up a whole host of devices to the DVD Player including mobile phones, laptops, computers, mp3 and MP4 players etc.

SD/MMC/MS Card Reader: Secure Digital/Multimedia Card and Memory Stick are all types of flash memory used in portable electronic devices from MP3/MP4 players, digital cameras, camcorders, mobile phones etc. A card reader for these devices ensures content on them can be played on the DVD player.

HDMI: High-Definition Multimedia Interface is an audio/video interface for transmitting uncompressed digital data.

It is the digital alternative to analog standards such as:

* RF

* Coaxial cable

* Composite video

* S-Video

* SCART

* Component video

* D-Terminal

* VGA

HDMI connects digital audio/video sources such as set-top boxes, Blu-ray Disc players, personal computers (PCs), video game consoles (such as the PlayStation 3 and Xbox 360), and AV receivers to compatible digital audio devices, computer monitors, and digital televisions

S-Video: Separate Video is an analog video signal that carries the video data as two separate signals, lumen (luminance) and chroma (color).

This differs from composite video which carries picture information as a single lower-quality signal, and component video which carries picture information as three separate higher-quality signals. S-Video carries standard definition video (typically at 480i or 576i resolution), but does not carry audio on the same cable.

** TV Encoders **

PAL: Phase Alternating Line is an analog color encoding system used in broadcast television is large parts of the world. DVDs with PAL encoding will only play on players that can decode this signal.

SECAM: Developed in France, it is an analog color encoding system for broadcast television. It is primarily used in France, parts of Eastern Europe some former French colonies.

NTSC: Developed in the USA, it is an analog color encoding system for broadcast television. Primarily used in the US.

DVB: Digital Video Broadcasting is (or will be) the industry standard for digital video in many countries around the world. It is used for satellite, terrestrial and digital terrestrial for portables (including mobile broadcasts).

ATSC: Advanced Television Systems Committee standard defines a digital broadcast standard for the US, Canada, Mexico and one or two other territories.

** Miscellaneous Terms **

Aspect Ratio: Aspect ratio is the fractional relation of the width of a video image compared to its height. The two most common aspect ratios in home video are 4:3 (also known as 4×3, 1.33:1, or standard) and 16:9.

Signal to Noise Ratio: Signal-to-noise ratio compares the level of a desired signal (such as music) to the level of background noise. The higher the ratio, the less obtrusive the background noise is.

Screen resolution: This refers to the number of rows and columns of pixels in the LCD display. So a screen with 800×600 resolution means it has 800 rows of pixels and 600 columns.

Bit rate: Bit rate is a measure of the rate of information content in a video stream. It is quantified using the bit per second (bit/s or bps) unit or Megabits per second (Mbit/s). A higher bit rate allows better video quality.

Modulation/Demodulation: This is a method of transferring digital data stream and converting it into an analog stream.

FFT Pattern: FFT refers to Fast Fourier Transform which is the algorithm used to unscramble the digital signals broadcast by television stations and broadcasters.

A FFT pattern is used in DVB-T transmissions and usually refers to signals being modulated for 2048, 4096, or 8192 carriers (2k, 4k, 8k mode, respectively).

FEC: Forward Error Correction is a system sending extra data with transmissions so that the television stations can quickly establish the cause of errors and fix them.

NES/SNES: Nintendo Entertainment System/Super Nintendo Entertainment System. These are gaming consoles released by Nintendo in the early 1990s. Many third-party devices come with these built-in, including portable DVD players.

ESP Protection: Electronic Skip Protection basically ensures playback of audio/video is skip free especially when mobile…say in a car.

** But why do YOU have to know all this? **

The digital consumer is aware of the interoperability between various digital formats and is generally looking for products that can double up in more than one function.

For example: a portable DVD player with a big enough screen to play back stills from a digital camera might mean the consumer will prefer to spend less on a camera with a big screen and use the portable DVD player instead for viewing pictures.

This is possible with the addition of the SD/MMC/MS card reader.

Similarly most family vacations today have a camcorder as a must have. For these consumers the ability to playback home videos on a larger screen is a must have.

A portable DVD player that accepts multiple video formats including NTSC, PAL SECAM etc. makes it more useful.

The ability to receive multiple TV input signals is essential given the changes taking place in broadcast technology. With Digital TV broadcast signals replacing analog across the world, it is essential that the portable DVD player have the required inputs to play the different TV formats.

Gaming is another “nice to have” feature on a family vacation.

The ability to either plug into existing gaming systems or in fact have a built-in gamer goes a long way in making a sale.

By knowing what the terms mean you are a long way towards knowing who to aim particular portable DVD players at and what features to play up and which points to ignore.

So get out there today, start studying up improve your listings and start selling to a wider market. Your bank balance will love you for it.

Now you know what the terms mean start listing portable DVD player models that have the features your customers want. See them now at Chinavasion.com or paste this URL into your address bar:

Portable DVD Players – Things To Know

Allen Reed asked:


In my humble opinion nothing makes a long trip easier (especially if you have kids). A portable DVD player is the ideal solution for those long plane rides or endless drives in a car to keep everyone entertained, especially when you have new hit DVD to play.

So what are some of things to keep in mind when selecting a Portable DVD Player? (Here are some items to consider in no particular order.)

Screen Size: Depending on where and when you plan on using your DVD player the most, size may really be a big factor in your decision. If you have a family that’s going to be watching movies in the minivan, you can bet you want to find a portable DVD unit with a larger screen so everyone gets a chance to view the movie. On the other hand, if you travel mostly by yourself or with a significant other, smaller may be the perfect thing for you, easy to haul and manage anywhere.

Disc Formats Supported by the Portable DVD Player: If you’re into creating your own home movies or music cd’s you need to look into whether or not the machine you want to buy can support other file types (CD-R, CD-RW, or DVD-R). Make sure your machine is capable of also playing just a standard music CD. Size of the DVD Player:

While most machines look like weight should never be a factor, there can be significant differences in weight from one type of portable player to another….as much as a couple of pounds. Read carefully so you know just how much each unit weighs. If you’re hiking across the country, weight can make a big difference.

Outputs that the Portable DVD Player comes with:

You may not think that this matters, but eventually you’ll wish you thought of this sooner rather than after you’ve purchased a unit. You’ll want a unit that comes with an S-Video outlet for video, as well as Optical Out for audio. These features will come in real handy when you get to your relatives that don’t have a DVD player, and gives you the option of watching a movie on their TV, by hooking into their TV and possibly their stereo…instant theatre for everyone.

How much do Portable DVD Players cost?

The price of a portable dvd player can vary quite a bit. Some of the dvd players with less features or quality will start at approximately $150.00 for a new portable player. On the high end of the price scale, you may be looking at paying as much as $600.00 for some of the better quality machines. Like anything, you usually get what you pay for.

Like all electronics, the price of portable dvd players has started to come down, as compared to a couple of years ago.

Another option is to look at is buying a used portable player, not highly recommended by me. Just my opinion with electronics, but you have no idea how electronics have been treated. The outside may look great, but who cares if all the important parts aren’t working properly. It’s not like buying a used baseball bat, you know what your getting by looking at it. If you can’t test out a used portable dvd player, I’d recommend you stay away from this option.

Quick Summary

From what I’ve seen on the market and looked at, I don’t think think that you’ll find any terrible portable dvd players. Like anything though, usually if you pay more you get a better quality product (dvd player in this case), better picture and features. All I know for sure is, when the kids start getting wired when we’re travelling, it sure is nice to put on a dvd movie and keep them entertained.



Portable DVD Player Buying Guide

David Rahimi asked:

Portable DVD Players are becoming very popular these days because they give you the ability to take all of your favorite movies, music, and pictures while you’re on the go. With a Portable DVD Player you’ll never have to be stuck in a car, airplane, or hotel room bored again!

It’s important that you know what you will be using your Portable DVD Player for before you buy it so that your all of your needs are met. Many people buy Portable DVD Players based on a single attribute, such as the screen size of the player. Though buying the biggest screen size can enhance your viewing experience, what good is a Portable DVD Player if you can’t carry it around with ease?

Below you will find a few things that our product specialists recommend our customers to look for in before buying a Portable DVD Player.

Screen Size: The screen size of a Portable DVD Player can make a significant impact on the viewing experience. If the screen is too small you won’t be able to see details that might play a big role in the movie. On the other hand, if the screen is too big the DVD Player might loose its “portability”, making it difficult to carry around.

Battery Life: If you plan on using the Portable DVD Player for long periods of time without being on charge, you may want to consider the amount of playback time the battery provides. If the battery life isn’t longer than two hours, then you probably wont be able to watch a movie from beginning to end. Try to get a portable DVD player that can offer more than two hours of playback time (so it lasts longer than the length of an average movie).

Disc Compatibility: You may want to consider the types of discs that the Portable DVD Player is compatible with before making your purchasing decision. For example, if you want to burn DVD’s from your computer, make sure that the Portable DVD Player can play the DVD-R or DVD-RW formats.

Portability: You may want to consider how “Portable” the DVD Player is before making a purchasing decision. If the DVD Player is too big and bulky, it might be difficult for you to carry around. Though as technology advances, even Portable DVD Players with large screen sizes are becoming extremely compact.

Included Accessories: The accessories that come with the Portable DVD Player should have a big impact on your purchasing decision. If you find a Portable DVD Player at a great price, but lacks many of the accessories that other Portable DVD Players come with you might just end up having to pay more in the long run. Consider accessories such as AC/DC Adapters, Remote Controls, AV Cables, S-Video Cables, Car Adapters, Car Mounts, Headphones, etc.

Definitions:

AC Adapter: An external power supply for your camera or other electronic device that converts AC (alternating current) from a wall plug to DC (direct current). Some AC adapters also double as rechargers.

AV Cables: Audio and Video Cables, which transfer the audio and video information from one electronic device to another.

S-Video (Separated Video): An analog video signal that carries the video data as two separate signals.
