Abstract: A browser-based email system has a thin client connected to a host mail server. The thin client implements a browser. The host mail server provides pages to the thin client, which can be rendered by the browser to present an email service to a user. The thin client is equipped to receive audio and video data and supports a user interface to facilitate capture of the audio or video data for inclusion in an email message. After a data stream is captured and stored locally at the client, the browser submits a request to the host mail server that contains a token in lieu of the data stream. The host mail server returns a response specifying a new page that contains the email message. The response also includes the token and indicates a location in the new page at which the audio or video data is to be rendered. Upon receiving the response, the browser inserts the data stream into the new page at the location and renders the new page.

Abstract: A method and system for simulating motion of a polygon on a display screen. The polygon may be included in a set of polygons used to model a three-dimensional object. The position of the polygon is defined by vertices tracked in a subpixel coordinate system existing in a computer-readable medium. The subpixel coordinates of the vertices are used to identify the pixels on the display screen having coordinates that correspond to subpixel coordinates lying within or, optionally, at the boundary of the polygon. The identified pixels are those that are to be lighted on the display screen to generate the image of the polygon. The display properties of the lighted pixels are selected by interpolation based on defined pixel display parameters assigned to the vertices of the triangle. As motion of the polygon is tracked in the subpixel coordinate system, the corresponding display on the display screen is repeatedly adjusted.

Abstract: An Internet access terminal automatically manages telephone communication with an Internet service provider to reduce inactive telephone line usage when the user toggles from the Internet mode to the television mode. A user who has been browsing the Internet can toggle the terminal to the television mode from the Internet mode, which has a particular state relating to the Internet page that is being viewed. The terminal saves state information representing the Internet state and monitors the time that elapses after the terminal is toggled. If a first period of time elapses, the telephone connection is dropped. If a longer, second period of time also elapses, the state information is discarded. Upon toggling back to the Internet mode, communication is resumed using the telephone connection and the Internet state is restored if the first period has not elapsed.

Abstract: A method and apparatus are provided for reducing flicker of an image defined in HTML format for display on a television monitor. When an image is received at a client computer that uses a television monitor and a browser to display HTML. documents, spatial analysis is performed on the image to determine whether the image would exhibit a tendency to flicker if it were to be displayed unmodified on the television monitor. One reason that flicker can be experienced is the interlaced nature of the television monitor, which can result in some portions of images being displayed on only one of the two fields in a frame depending on the spatial frequency of the portions of the image. If the spatial analysis indicates that the image would exhibit a tendency to flicker, a flicker reduction filter is selected and applied to the image before it is displayed on the television monitor using the browser. Otherwise, the browser displays the image without flicker reduction filtering.

Abstract: A graphics rendering system creates an image based on objects constructed of polygonal primitives. Aliasing effects in the image are reduced by applying an anti-aliasing scheme to the areas of the image representing silhouette edges of the objects. The silhouette edges are anti-aliased by creating anti-aliasing primitives which vary in opacity. These anti-aliasing primitives are joined to the silhouetted edges, and create a region in the image where the objects appear to blend into the background.

Abstract: A method of providing a document to a client coupled to a server is provided. The server provides a number of Internet services to the client, including functioning as a caching proxy on behalf of the client for purposes of accessing the World Wide Web. The proxying server includes a persistent document database, which stores various attributes of all documents previously retrieved in response to a request from a client. When a Web document is retrieved from a remote server in response to a request from the client, the database is consulted and the stored information relating to the requested document is used by the server in transcoding the document. The document is transcoded for various purposes, including to circumvent bugs or quirks found in the document, to size the document for display on a television set, to improve transmission efficiency of the document, and to reduce latency. The transcoder makes use of the document database to perform these functions.

Abstract: Browser software implemented in a set-top box as part of a client system communicating over the Internet with one or more servers allows a user to navigate using a remote control through World-Wide Web pages in which a plurality of hypertext anchors are displayed on a television. A user input entered from a remote input device is received by the client system over an infrared (IR) link. The user input specifies a direction in which the user wishes to move a selection relative to a currently selected hypertext anchor. Based on the user input, a determination is made of which one of the hypertext anchors is a best selectable hypertext anchor, and that hypertext anchor is then selected and indicated as such to the user. The user interface allows for the selection of hypertext anchors which are part of either clientside or server-side image maps.
