Audio Video Converters

A media container format (or sometimes referred to as wrapper format) is a format that can contain various types of data such as audio and video data. The data is compressed using a codec.

A codec (a compound of coder and decoder) is an algorithm used to compress and/or decompress a multimedia data stream in order to reduce the amount of bytes needed to store or send.

Some container formats are limited to audio, like WAV files for Windows, AIFF for Mac and XMF; some are limited to still images such as FITS and TIFF. There are also containers that are flexible; it can hold several types of audio, video and other media such as ASF files for Windows, MP4 and Matroska. The most common multimedia containers are:

  • 3GP – used by mobile phones
  • ASF – standard WMA and WMV container
  • AVI – standard Windows container
  • Matroska – open standard container
  • MPEG – standard container for MPEG-1 and MPEG-2
  • MP4 – standard container for MPEG-4
  • Ogg – free and open standard container for codecs Vorbis (audio) and Theora (video)

The distinctions between different container formats come up from five (5) main issues:

  • Popularity. Widely supported container.
  • Overhead. Example: A two-hour film may be 3MB larger when in AVI than when in Matroska (MKV). The overhead is the difference between AVI and MKV which is 3MB.
  • Support new codec functionality and features. Some older container formats does not support codec feature such as VBR audio and B-frames.
  • Subtitles, chapters, meta-tags, and user-data support.
  • Streaming media support.

Here is a comparison of the different popular container formats today (from Wikipedia).

  1. Nowadays anyone can install a state of the art video system in his or her car without spending exorbitant amounts of money, and mobile audio and video equipment has become such a common place in cars that we no longer get too surprised at the sight of such systems. However it wasn’t that long ago, let’s say just over ten years, that being able to spot a video screen displaying images inside a vehicle was something out of this world.

When looking at the evolution of the car audio-video industry since 1995, we can’t help but marble how far these systems have evolved in just over 10 years, and it makes you wonder where the technology will be headed in the next decade. In 1995 for instance, car makers were barely on the brink of discarding the old tape deck players and beginning to standardize on CD players. Today it is becoming rarer and rarer to spot a car on the street with one of those old CD players, which just 13 years ago were still considered the latest and greatest in technology.

And soon after the CD player evolution, came the MP3 players, which were closely followed by video screens with few capabilities like the ability to display a limited amount of theme graphics to accompany the music. Even these systems were at the time considered state of the art technologies worth competing against.

By contrast today’s car audio systems, come integrated with an array of capabilities both visible and hidden, which make the old systems look ancient. Today’s video display resolutions are far clearer and produce less glare, DVD and game playing capabilities are built right in, IPOD and MP3 storage capability are more and more common place. Cell phone receiver support is also becoming more standard. Not to mention the advent of digital systems like XM and Sirius as well as the terrestrial digitization of the airwaves

Adding Or Upgrading an Audio

When integrating an audio video system into a recreational vehicle special care must be taken. There are a lot of considerations you need to think about before you decide what type of system is right for you and your family. With today’s manufactures offering 12volt standard and marine grade systems, adding indoor/outdoor audio was never easier. Since most RV’s and campgrounds have a 110volt supply, this gives you the ability to integrate home AV equipment with your 12volt systems.

We should first talk about your options and what you may want your system to do. Video is one of the main components of a good RV system, considering how much time is spent inside your RV (bad weather, preparing meals, entertaining the kids and for motor homes when your driving). With the ability to source audio and video signals you can have one central media player device and display it’s contents in multiple zones.In other words you can watch a movie on all TV’s or watch different shows on each TV independently. So the children can play games or view their shows in their room and you can listen to music or watch a movie in the living room and even finish it in your bedroom. With the introduction of marine grade flat panel TV’s, it’s even possible to have video outside under your awning. There are many options for your video source, most trailer parks offer cable TV. Satellite TV is another good option and can be set up on site, or a mobile dish system can be installed on the top of your RV, this is a great option for motor coaches where your passengers have the ability to watch TV as you drive. You may also use a digital antenna to receive free broadcasting where available. Now that we have covered network broadcasting, let’s talk about media players. A typical source would be a DVD/CD or Blu-ray player, remember when making your choice that you can play all types of audio and video on a Blu-ray but can’t play Blu-ray on a DVD/CD player. A media sever is a compact hard drive unit that allows you to store movies, albums, photos,etc., these are a great option if you already have all of your media on your home computer, just upload to the server and take it with you. The navigation of the media server is similar to an iPod screen and is displayed on the television.

Now that we’ve covered video let’s talk about audio. Most new RV’s come with a stock stereo system of some sort, but the quality isn’t there (if it is turned up loud it crackles and sounds distorted). This isn’t as bad as it sounds, often with the addition of a good amplifier and replacement of the stock speakers this problem is resolved. Care must be taken when performing this type of installation, make sure you know what wires go where, and don’t add extra speakers without powering them correctly. Adding outdoor speakers is one the most common upgrades. Before doing so make sure that you buy the correct speakers, they must be marine grade to with stand the elements. Just like the video system your audio can be sourced. So before you buy, think about what your trying to accomplish. One thing often overlooked is how loud you really need your system to be, remember most RV parks have rules and quiet time so spending lots of money on a killer audio system may be a waste and would have been better spent on another flat panel, media server, etc..

Installation is as important as the equipment you choose to buy. Unless you have done this type of work before it’s highly recommended that you have it done professionally. Remember you will be dealing with two different electrical system both 12V and 110V, serious damage can occur if things aren’t hooked up correctly. Here at Serious About Sound LLC our technicians can help you with the design and choosing the right products for you and your families needs. We also offer installation of all our maufacturer’s products. We are fully insured and have a secure facility to accommodate most larger size RV’s.

The Evolution of Audio Video

Audio video conferencing is a shorthand way of describing a virtual conference where no one has to leave her office to meet up with the rest of the group. A virtual conference may use telephones, televisions, computers, conferencing software, collaborative software, file sharing, headsets, the Internet, or any combination of these equipments and tools. Slide presentation, streaming audio, and document sharing are some of the extras you can incorporate into this conferencing method. The ultimate goal is to make the meeting as realistic as possible, where everyone can see each other, hear each other, view and modify projects, and so on – all at a cost that eventually pays for itself in travel savings.

The audio video industry has yet to work out all of the kinks. As you can imagine, there can sometimes be technical difficulties in which lines can get torn down in a storm, computers and other equipment can malfunction, and so on. Furthermore, audio video conferencing doesn’t work very well for complicated communication techniques, such as those used in closing a sales deal. Audio video conferencing lends a rather impersonal air to meetings, and socializing and bonding don’t take place as they would in the real world.

You can set up for audio video conferencing in a number of different ways. The older method, still great for a wide variety of teleconferencing purposes, is to have one group in one room, another group in another room (perhaps in another city or country), and have them talk to each other. Each of the two groups utilizes a television, a video camera mounted on the television, a speakerphone, and perhaps some file sharing software for collaboration on computer projects. The newer style is online audio video conferencing, wherein each participant has her very own station in her very own office. This utilizes a computer, the Internet, a web cam, a headset, and file sharing software. This new method allows for even greater ease of planning and attendance, applicability to collaboration, and mobility. You could attend a web conference on the beach while the other attendees are on a train, at home, in a restaurant, or anywhere else.
