Abstract: A system and method for viewing material displayed on an electronic device. When a user desires to view a document, only a portion of which is viewable on a display at a given moment, the portion is displayed on the display as a primary image. A secondary image is then generated, with the secondary image including the portion and additional material of the document not part of the primary image. The secondary image is superimposed over the primary image on the display when a user scrolls through the document such that both the secondary image and the primary image are visible to the user.

Abstract: A method and apparatus are provided for measuring a bit rate between a client and a server. In an embodiment of the invention, a number of bits included only within one or more transaction units are measured over a time period. The time period is a sum of time durations of each of the transaction units. In an embodiment of the invention, bit rate measurements are performed on a server and in another embodiment of the invention bit rate measurements are performed on a client. Embodiments of the invention include adapting, by the server, of content to be sent to the client based on the bit rate measurements. Embodiments of the invention further include reporting the measured bit rate to the server when the bit rate measurements are performed on the client. Other aspects of the invention include sending an indication of the measured bit rate and a desired bit rate to the server when bit rate measurements are performed in the client.

Abstract: A method and apparatus is provided for transcoding content communicated in a network. The method features the step of transcoding the content based on permissible transcoding operations authorized by a content creator. The permissible transcoding operations include any transformation, alteration or manipulation of the content. The permissible transcoding operations include: a resolution reduction for reducing a resulting resolution of the content; an aspect ratio modification for specifying a maximum deformation that can be applied to the content when modifying its resolution; a color and bits per pixel modification for specifying if an image can be converted to gray scale or not, and minimum bits per pixel (bpp) or number of colors (or levels) that can be used; cropping for specifying a region of an original picture that must be preserved; and a quality reduction for allowing the content to be further modified by adding some distortions to an image. The content may be images, graphics, video or audio.
