Multi-functional user interface using slice-based encoding
First Claim
1. A method for encoding an interactive program guide, comprising:
- defining a series of pages of the interactive program guide, each page represented by a different graphics portion and by a video portion common among the pages during one time period;
defining a set of slices for each graphics portion and each video portion of each page of the interactive program guide, each slice in the set of slices including one or more macroblocks;
assigning an identifier to the slice of the video portion common among the pages during the one time period;
assigning the same identifier to slices of different video portions during other different time periods wherein the slices of different video portions correspond with a graphics portion common among the slices of different video portions during the other different time periods;
scanning each of the sets of slices and assembling a transport stream;
transmitting the slices of the common video portion one time for the series of pages of the one time period;
transmitting the slices of the different video portions and the common graphic portion of the other different time periods; and
rendering the series of pages of the interactive program guide from the slices of the common video portion assigned the identifier and from the slices of the different video portions and the common graphics portion assigned the same identifier, for the one time period and for the other different time periods.

Abstract
Methods for slice-based encoding of program guides and user interfaces. The program guides include multiple video streams for picture-in-picture and other applications. A method for encoding the program guide includes encoding a first set of slices for each of a plurality of graphics pages; and encoding a second set of slices for each of a plurality of video streams. The user interfaces are multi-functional and may be used for electronic commerce and other applications. A method of generating the user interface includes encoding a set of slices for each of a plurality of objects, each object being characterized by an identity, at least one attribute, and at least one operation. In one embodiment of this method, the plurality of objects include an electronic commerce object, where the electronic commerce object is attributed with a first hyper text markup language (HTML) page.

9. A system for encoding an interactive program guide, comprising:
-
a processing unit; and a memory, which when executed by the processing unit, perform steps of; defining a series of pages of the interactive program guide, each page represented by a different graphics portion and by a video portion common among the pages during one time period; defining a set of slices for each graphics portion and each video portion of each page of the interactive program guide, each slice in the set of slices including one or more macroblocks; assigning an identifier to the slice of the video portion common among the pages during the one time period; assigning the same identifier to slices of different video portions during other different time periods wherein the slices of different video portions correspond with a graphics portion one of the graphics portions common among the slices of different video portions during the other different time periods; scanning each of the sets of slices and assembling a transport stream; transmitting the slices of the common video portion one time for the series of pages of the one time period; transmitting the slices of the different video portions and the common graphic portion of the other different time periods; and rendering the series of pages of the interactive program guide from the slices of the common video portion assigned the identifier and from the slices of the different video portions and the common graphics portion assigned the same identifier, for the one time period and for the other different time periods. - View Dependent Claims (10, 11, 12, 13, 14, 15)
