Method for realizing interactive television watching effect enhancing system based on metadata control

Abstract

The invention relates to a method for realizing an interactive television watching effect enhancing system based on metadata control. An extensible metadata dynamic driving model is constructed; key information, such as the time position for effect enhancement, the type of support equipment, an action response manner and a data provider, is defined as standardized metadata; furthermore, the metadata is allowed to be dynamically extended in an operation process; parameters are transferred to effect enhancement equipment through play equipment used by a watcher, such that the working state of the effect enhancement equipment is dynamically controlled; besides provision of light, the sound effect, embedded advertisements and object introduction associated with a film and television content scene, associated information, such as comments and plot branch control, input by users in a watching process in real time, is also allowed to be dynamically published; the effect that the same film and television content can be universally applicable in different environments can be realized; and the interactive television watching effect enhancing system having the standardability, the interconnectivity, the intercommunity and the extendibility is constructed.

Description

Technical field [0001] The invention relates to a smart TV technology, in particular to an implementation method of an interactive TV viewing effect enhancement system based on metadata control. Background technique [0002] The interactive TV service needs to be realized through a digital TV set-top box on the user side, including functions for users to watch live programs, use on-demand services, and browse various interactive applications, and provide conventional services such as watching videos and listening to audio. With the development of information technology, equipment with enhanced effects began to appear, such as ambient light, ring curtain wall, panoramic surround sound, motion displacement, weather simulation, etc. Related equipment has been widely used in high-quality 4D theaters, IMAX theaters, etc. In the video playback environment. [0003] With the introduction of the concept of smart TV operating system, a new generation of smart TV operating system set-top bo...

AI Technical Summary

Problems solved by technology

[0004] With the development of the Internet of Things, effect-enhancing devices have begun to appear, such as ambient light, background walls, panoramic surround sound, etc., but limited by the lack of content and program sources, they cannot play a role when watching ordinary film and television programs.

Because the standards adopted by these devices are not uniform, the working mechanisms, processing protocols, and applicable scenarios are also different, and the existing interactive TV programs have not standardized the adaptation methods, so the device interoperability of such devices is relatively poor. poor, which makes the system construction cost higher, further restricts large-scale promotion, and cannot achieve theater-level effect enhancement in the user viewing environment

There are many difficulties in actually building a theater-level effect enhancement environment
