[. . . ] If the browser is communicating with the network gateway, the network gateway sends the image to the browser without scaling it. However, network gateways typically have a size limit for images. Users can specify a limit for the number times that animations can loop. Animated GIFs can repeat either the default value of 10 times or the number of times specified in the GIF repeat value. In BlackBerry® Device Software version 4. 2. 2 or later, users can specify the image quality for images rendered in the BlackBerry Browser. The lower the image quality, the faster the image is rendered. Progressive image rendering In BlackBerry® Device Software version 4. 2. 2 or later, the BlackBerry® Browser renders images progressively. When the browser retrieves a web page, a low quality version of each image displays quickly. After the entire web page is downloaded, the browser retrieves the additional image file segments from the network gateway. The low quality images are enhanced as the additional image file segments arrive, until they meet the image quality that is specified by the user. Progressive image rendering is available with the following browser configurations and the associated network gateways: · The BlackBerry Browser configuration and the BlackBerry MDS Connection Service network gateway · The Internet Browser configuration and the BlackBerry Internet Service Browsing network gateway Support for media streaming In BlackBerry® Device Software version 4. 3 or later, the BlackBerry® Browser supports streaming of audio and video files. The BlackBerry Browser supports the following media types: · · Video: WMV, h. 263 Audio: MIDI, MP3, MP4, Wav The browser supports media streaming over the HTTP or RTSP protocols. When a user clicks a link to an audio or video file, the user can open the file, save it to the media card or device memory, or cancel the download. If the user opens the file, the BlackBerry Browser opens the media application and the file begins streaming. When the content is finished streaming, the user can close the media application to return to the browser. Streamed content is not saved; users cannot replay media unless they download it again. The network gateway might limit the size of the file that can be streamed. There are no size limitations if the content is streamed over a Wi-Fi® connection. Support for web feeds In BlackBerry® Device Software version 4. 2 or later, the BlackBerry® Browser supports the following web feed formats: 21 Fundamentals Guide Script processing · · RSS 0. 9, 1. 0, and 2. 0 AtomTM The browser lists web feed items by date, and lists unread items in bold. When the user opens an item, the content appears in a new page. The BlackBerry Browser does not act as an aggregator, and it does not store web feed content except as cached data. Users can add web feeds to the bookmark list. In BlackBerry Device Software version 4. 2. 2 or later, the BlackBerry Browser supports RSS enclosures, designed to provide users with access to media files that are located at the URLs specified in the <enclosure> tag. In earlier versions, these links were ignored by the browser.
