What is the difference between NTSC VHS and PAL VHS formats?

NTSC(National Television System Committee) is the TV format in the United States and Canada.
PAL (Phase Altering Line) is the TV format used in most of Western Europe and Asia.

America and Canada use NTSC. This was the first color tv broadcast system. NTSC is also used in Asia, including Japan. Western Europe and Australia use PAL. PAL was developed in the early 1960's Eastern Europe and France use SECAM(or sequential couleur avec memoire -sequential color with memory.) SECAM systems can play PAL tapes.

What do I need, NTSC or PAL?

The Video Journal of Orthopaedics provides both NTSC VHS and PAL VHS at the same price. Below is a chart indicating the broadcast systems of many countries. If you do not see your country below, we will be happy to find out which system you need. If you have questions about which system to use, email us: customersupport{at}vjortho.com

Why DVD?

DVD, which once stood for digital video disc or digital versatile disc, is the newest generation of optical disc storage technology. It's essentially a bigger, faster CD that can hold cinema-like video, better-than-CD audio, and computer data. DVD has the capability to produce near-studio-quality video and better-than-CD-quality audio. DVD is vastly superior to consumer videotape and generally better than laserdisc.

What do I need to play a DVD?

Today, every major computer manufacturer has both desktop and laptop models that include DVD-ROM drives. There are many good set-top players available as well. Video and audio performance in all modern DVD players is excellent. Personal preferences, your budget, and your existing home theater or computer setup all play a large role in what player is best for you.

Is VJO available on CD-ROM?

CD-ROMS only hold ten minutes of full motion video. Due to the in-depth nature and total run time of our productions, there is not sufficient memory on a CD-ROM. DVDs hold 240 minutes of full motion video, making them an ideal format for our productions.

FAQ for Streaming Video

Q: What is "streaming media"?

A: audio and video files that play directly from the network to the computer. This method never saves the file to the computer and cannot be copied.

Q: What is buffering?

A: When a file is streamed, it is played entirely over the network. No network is 100% reliable or consistent, so the player software stores some of the stream, 10 seconds for example, before playing it. That way, it always has 10 seconds worth of material to play if there’s a network problem, so the connection can be fussy for up to 8 or 9 seconds, and the viewer will never see a problem because the player just plays the buffered material while it waits for more of the stream over the network.

Q: What is the minimum internet connection speed needed?

A: 128 Kbps. This represents the low speed end of Cable/DSL connections.

Q: Once I activate my streaming video on VJO, can I watch from any computer?

A: Once you purchase streaming video you will have instant access only from the computer which you used to make your purchase. You will then receive a subscriber number via e-mail which, once activated, will enable you to access the streaming video from any computer that meets the system requirements.

Q: For viewing, do I need to select my Internet connection speed?

A: No. Your Internet connection speed is automatically sensed and will play at the fastest speed that your computer will accept at that time.

Q: For viewing, do I need to select my media player type?

A: No. Our sole player is Windows Media Player, which is available via free download at http://www.windowsmedia.com/download/.

Q: I’ve tried everything and I still cannot get the videos to play. What do I do?

A: First of all make sure you have the most recent version of the proper Windows Media Player application that is suggested for your particular computer. Next, make sure it is properly installed by going to Windows Media and try to view other content created for these players. If you succeed, then email us and let us know.

Q: What if I am behind a firewall and cannot see the videos?

A: In this situation it may be impossible to access streaming media. Please email us to let us know your specific problem. We will then see if there is a way to solve it or make arrangements to get the content to you via other options.

Q: How can I determine my Internet connection speed?

A: This can be assessed at http://www.2wire.com/meter/bmresult.html. It is recommended to make 3 measurements and then average those results to ensure accuracy.

Q: How can I find out which streaming video players are installed on my computer?

A: Go to http://detect.videodome.com/ to identify which media players are installed.

Q: What are my screen size options?

A: There are basically 2 options for screen size. Initially your image will be presented in a default size that will occupy? 20-50%? of your computer screen (the range is a function of your set screen size on your computer). In addition, you can select “full screen” from beneath the image in the same pop-up screen. Full-screen is best appreciated from a distance of 3-6 feet from screen. To return to the default size, press the’esc’ button on your computer keyboard.
