A portable electronic device displays a plurality of icons (e.g., graphical objects) in a region in a touch-sensitive display; detects a predefined user action, with respect to the touch-sensitive display, for initiating a predefined user interface reconfiguration process; and varies positions of one or more icons in the plurality of icons in response to detecting the predefined user action. The varying includes varying the positions of the one or more icons about respective average positions.

A computer-implemented method, for use in conjunction with a portable electronic device with a touch screen display, comprises displaying at least a portion of a structured electronic document on the touch screen display, wherein the structured electronic document comprises a plurality of boxes of content, and detecting a first gesture at a location on the displayed portion of the structured electronic document. A first box in the plurality of boxes at the location of the first gesture is determined. The first box on the touch screen display is enlarged and substantially centered.

Portable Electronic Device, Method, and Graphical User Interface for Displaying Structured Electronic Documents

Methods, systems, and apparatus, including computer program products, for presenting user interface elements. A first page of one or more user interface elements is presented on a touch-sensitive display. Each of the user interface elements corresponds to a respective application. A gesture performed on the touch-sensitive display is detected. In response to the detected gesture, a second page of one or more user interface elements is presented on the touch-sensitive display.

Application menu user interface

In accordance with some embodiments, a computer-implemented method is performed at a portable multifunction device with a touch screen display. The computer-implemented method includes: displaying a home menu comprising a plurality of application launch icons; detecting activation of any respective application launch icon; and, in response to detecting the activation, displaying a first animation of a transition from display of the home menu to display of an application that corresponds to the activated application launch icon. The first animation comprises expanding an image of the application.

A video server adaptively selects an appropriate video encoding standard and an appropriate video encoding rate for encoding video content to be downloaded to one or more video client devices over a communication network. The video server adaptively selects the video encoding standard and the video encoding rate based upon factors such as the data transmission rate of the communication network, the processing speed of the video client device, or the type of the video content to be downloaded. Once the video encoding standard and the video encoding rate are selected, video content can be transcoded prior to downloading to one or more video client devices. During the download, the video content may be adaptively transrated, such as in response to a change in the data transmission rate of the communication network.

Method and system for adaptive transcoding and transrating in a video network

Transcoding proxies for mobile World Wide Web access have been developed. In the near future, wideband mobile communication systems such as IMT-2000 will emerge, and these proxies will have to cope with a variety of media such as video. In this article we identify issues involved in viewing a video stream in a mobile computing environment; to handle these issues, we propose a video transcoding system and its control method. These mechanisms provide stable transmission of video data and comfortable video viewing on user clients by estimating the communication conditions, client device capabilities, and user preferences.
