Laptop Repair Made Easy. Card Recovery Professional. Related Category Video Game. On a standard non-widescreen TV, the Xbox displays content that is slightly wider than normal. Rather than x , the Xbox starts with a base resolution of x This content is scaled down to x , which does not match the ratio of the TV screen—the closest standard resolution is x To fit the proportion of the TV screen, the content is then compressed horizontally from pixels to pixels.
If you determine that your design needs adjustment for display on the Extender, you can apply the Matrix visual filter to the page—as shown in the following script—to correct the distortion and display the page at x pixels:. If you call this function from your onload event, it should correct the distortion. Note It is recommended that you let your other onload functionality take place first.
However, this filter will not correct the distortion in an ActiveX control such as Macromedia Flash. If you are using Flash to generate your user interface, you need to correct the distortion separately. The simplest way to do this in HTML is to set the scale parameter for your Flash object to "exactfit", and then use script to widen the Flash movie to 1.
For example, you could add the following line of code to the previous function:. In certain cases, images on your hosted HTML page might only be partially displayed—or fail entirely—when the page loads.
Images fail to be displayed because the code most applications use for scaling the page at different resolutions using the CSS Zoom property is executed in a manner that is asynchronous with the page's display process. You should test your hosted HTML pages carefully on an Xbox Extender to make sure that all images are displayed correctly and consistently over several page refreshes. This issue occurs on Xbox Extenders but not on third-party Extenders. If your images are not displayed correctly, the workaround is to execute the zoom statement using the setTimeout method, which forces the page to scale in a synchronous manner.
The following function shows how to scale elements when resizing a page. The only change is the addition of the setTimeout method. The SDK version of the zoom statement is as follows:. Because Extender devices do not support a hardware keyboard, the task of text entry on any Extender device is accomplished with the remote control through a mechanism provided by your application to translate input from the remote control into text characters.
Typically, such text entry is done by using an onscreen keyboard. In an onscreen keyboard, characters are represented as buttons on the screen, and users use the remote control to move the focus and select. Buttons are usually provided for access to additional characters such as the Shift and More buttons as shown in the following figure:. For extensibility applications on the Windows Media Center PC it is possible to enable text entry using a triple-tap mechanism, but this approach is not recommended because it will not work on Extenders.
For triple-tap—a model commonly used for text messaging on mobile phones—the user presses the number keys on the remote control to select characters. Each number key has several characters mapped to it, and key presses cycle through the key's assigned characters. Because the Extender does not enable your extensibility application to handle key press events for the number keys, and because some Windows Media Center remote controls do not have number keys, users will not be able to use a triple-tap mechanism on an Extender.
The recommended approach is to use an onscreen keyboard. This section describes recommendations for testing extensibility applications on Extender devices. As you develop your application, it is essential to create a testing environment that includes the different types of devices that users will be using:. In addition to your normal testing routine, you should conduct a side-by-side comparison of each view in the user experience on the Windows Media Center PC, the Xbox Extender, and a third-party Extender.
Watch carefully for the following issues on Extenders:. The goal of Extender testing is to ensure that the experience on the Extender devices is comparable to the experience on the PC, or at least that it degrades gracefully. Once the initial installation has taken place, the overall user experience should be equally comfortable and intuitive on both the PC and Extender devices.
To do this, follow these steps:. Start Windows Media Center. Click Tasks, and then click Settings. Click Extender, and then select the Xbox console. Click Uninstall. After the uninstall process is complete, click Extender again, and then click Configure. When you're prompted for the setup key, follow these steps:. On the Xbox Media Remote, press the Y button. Press the Windows Media Center Start button. Note the eight-digit setup key.
Return to the computer, and then enter the setup key. Complete the Extender setup.
