Embodiment Construction

[0018] Program Specific Information (PSI) includes program guide information and information used in identifying and assembling individual data packets for retrieval of selected program channel content. Program specific information and associated program content should be structured to facilitate communication of multimedia objects including audio clips, video clips, animations, still images, Internet data, email messages, text and other types of data. A multimedia object is a data entity that can be viewed as an independent unit and is related to an image or program guide unit within each program. For example, multimedia objects may be included in a composite video image representing a program guide or video title. This data structure supports one-way communication applications such as passive viewing and two-way communication applications such as interactivity type functions, as well as saving applications.

Abstract

A program specific information data structure facilitates communication of program content and program guide data with attached multimedia objects including audio, video, animation, still image, Internet, Email, text and other types of data. The data structure supports uni-directional communication applications, e.g. passive viewing, and bi-directional communication applications, e.g. interactivetype functions. A decoder (100) processes packetized program data and program specific information containing ancillary description information including multimedia object type, location and other descriptive indicators. These indicators are used in acquiring (22, 60), and decoding (30, 37, 60) multimedia objects derived from different sources for presentation (45, 50) in composite video images representing video program content or program guides, for example. Additional ancillary location and acquisition description information enables acquisition of supplementary program specific information elements and program content data.

Description

[0001] This application is a divisional application of the invention patent application with the application number 98810226.9 and the application date on October 13, 1998. technical field [0002] The invention relates to the field of digital signal processing, in particular to the acquisition, formation and processing of multimedia program guide and program content information. Background technique [0003] The home entertainment system (PC / TV system) combined with the functions of personal computer and TV is becoming more and more a common, multi-source and multi-target communication device that interacts with users. Such multimedia systems need to communicate between multiple locations in different data formats for various applications at the request of users. For example, a PC / TV system may receive data from satellite or terrestrial sources including High Definition Television (HDTV) broadcasts, Multipoint Microwave Distri...
