How to Use This Website
The Densho website provides a wide range and depth of content. Included in this content is the use of primary sources, which includes text, image, audio and video materials. Below is a discussion of the organization of the website and the technology needed to use the multimedia portions.
The Densho website is organized into six sections.
Causes of the Incarceration
Top Navigation Bar
The top navigation bar is used to go to the main sections of this website. For example, if you click on "Learning Center" in the top navigation bar, you will jump to the "Learning Center" home page.
Left Navigation Bar
The left navigation bar contains an expanding outline of the pages in the section you are viewing. Each page listing in the outline can contain two parts:
Clicking on the name of a page retrieves that page. Clicking on the sideways arrow icon opens the outline to the next level. Clicking on a downwards arrow icon closes a level. When a page is open, the name of the page in the outline will be highlighted (white title text on a green color bar).
Web Browser Software
For the best experience in the Archive, Densho recommends Mozilla Firefox or Microsoft Internet Explorer running on either Microsoft Windows 2000/XP or MacOS 10. Although not required, we also recommend XGA (1024x768) or higher screen resolution.
The Archive uses technologies called "streaming" and "progressive download" to deliver audio and video clips. These technologies allow you to watch or listen to the presentation without having to wait for the entire file (which is usually quite large) to be transferred onto your machine.
There are several different formats popular on the Internet today. In the Densho Digital Archive, we use Adobe's Flash Media format. To view or listen to the clips in the Archive, you must have the Adobe Flash Player. Adobe has a free player version available for Windows and Macintosh machines that you can download using the link below:
If you are not sure whether the player will work on your computer, please read the technical requirements at Adobe's website before downloading.
In addition to streaming video and digitized photos, some of the digital items in the Densho Digital Archive are in Adobe's Portable Document Format, or PDF. To view these documents you must have the Adobe Acrobat Reader. Adobe has a free version available for Windows and Macintosh machines that you can download using the link below:
Internet Connection and Bandwidth
Streaming media technologies deliver the audio and video information to your computer as the media is actually playing, therefore, the speed or "bandwidth" of your connection to the Internet is very important. In order to view Densho videos, you must have "broadband" Internet service (e.g., cable modem, DSL or other >256kbs connection). You can listen to the audio-only versions of Densho media with a regular dial-up modem connection.
Sometimes, even with a high-speed connection, the quality of your experience may not be as you would expect. The video might appear blurry, the audio might skip or the player may stop and report that it is "buffering". Often, these problems are due to network congestion, and may resolve themselves if you simply try back later.
Note to Educators
If you are accessing the Archive from your school, we strongly recommend speaking with the person responsible for information technology (e.g., Instructional Technology Coordinator) before using audio or video clips in a classroom lesson. While the Archive uses standard Internet technologies, your school or district may have set up your software, computers or network connections in a manner that will require special configuration.
"The left navigation bar doesn't work."
Microsoft Internet Explorer for Windows user:
Microsoft Internet Explorer for Macintosh user:
"When I play video or audio, the clip stops playing. I sometimes see the word 'buffering' or the icon in the player is moving, but nothing is happening."
When Internet traffic is high, streaming video and audio can buffer, pause or skip when the connection becomes too thin to consistently support the stream. These degradations in quality depend on a number of factors, including Internet traffic congestion and your own bandwidth. Try playing the video or audio again (or at another time of day). If you are having trouble playing video, try selecting audio instead.
"My video image quality is poor."
Image quality can be affected by display settings, connection rate, Internet congestion, having unnecessary applications open on your computer or having a computer not fast enough to effectively play video. Below are some suggestions to improve video quality.
For a Windows computer:
Check your display settings. We require a display resolution of at least 800x600 pixels (1024x768 is recommended) and 16-bit color depth. You can change your display settings by right-clicking on the desktop and choosing Properties from the pop-up menu. Click the Settings tab in the Display Properties dialog box. If the setting indicated under Screen area is less than 800x600 pixels, move the slider toward More until the resolution meets our minimum requirements. Colors should be set to High Color (16 bit). To implement these settings, click OK.
For a Macintosh computer:
"My media player doesn't work anymore"If you have problems or questions about the Adobe Flash Media format or software, please visit the Adobe website.
You may need to re-install your media player, especially if you have upgraded or changed your web browser.
