US Patent:

6587116, Jul 1, 2003

Filed:

Nov 18, 1999

Appl. No.:

09/443052

Inventors:

Ian Hendry - San Jose CA
David Hayward - San Francisco CA
John Calhoun - Sunnyvale CA
Eric Anderson - Los Gatos CA

Assignee:

Apple Computer, Inc. - Cupertino CA

International Classification:

G09G 502

US Classification:

345600, 345597

Abstract:

Aspects for maintaining and providing a calibrated color environment for display devices of a computer system. In an aspect of an exemplary method, the method includes determining relevant state data, including a framebuffer driver state and a display driver state. The method further includes saving the relevant state data as calibration information for the calibrated color environment. The relevant state data includes information about a display that has an effect on color, such as a framebuffer driver state, a display driver state, and phospher characteristics of the display.

International Classification:

G06F 15/16

US Classification:

709217

Abstract:

A content streaming system, such as an HTTP streaming system, can use a variant audio playlist that identifies different audio playlists, such as one playlist in English and one playlist in Spanish, for the same program such as a video program which is specified by a video playlist which can be separate from the variant audio playlist. A client can use the variant audio playlist to select a particular audio content for the same program, and the particular audio content can be referred to by one URL in the variant audio playlist, among a set of alternative URLs, in the variant audio playlist, for alternative audio content.

Appl. No.:

8/954084

Assignee:

International Classification:

G06F 314

US Classification:

707536

Abstract:

A computer performs designated operations on text that can be in any of a variety of different languages, rather than being restricted to a single language for which the computer was designed. A library stores operators and functions that can act upon character strings. Also stored within the library are sets of rules which identify the casing, ordering and matching of characters within different writing systems, or human languages. When a user of the computer designates a particular operation to be performed with respect to a text string, the writing system associated with the text string is identified. This identification can be made with reference to the typefont that is used to display the text string. Once the writing system for a string has been determined, appropriate tables and data structures that define and encode language rules for that writing system are accessed and applied to the operation on the string. For example, when comparing strings of text, the computer will be instructed whether to compare encodings on the basis of one byte at a time or multiple bytes together.
