Problems solved by technology

[0019] The purpose of the present invention is to provide a method for optimizing metadata of audio-visual resources in Internet TV, to solve the problem of using each audio-visual resource in the audio-visual resources with common attributes as an independent on-demand content in the prior art. A large amount of redundant data has led to an increase in the workload of resource providers to input information, and the problem of reduced network transmission efficiency and set-top box download speed
[0020] Another object of the present invention is to provide a system for optimizing metadata of audio-visual resources in Internet TV, which solves the problems that resource providers have a large workload for inputting information, and the problems of network transmission efficiency and set-top box downloading speed are reduced

Embodiment Construction

[0082] The core of the present invention is to define the audio-visual resources with common attributes as a class of on-demand, and expand the metadata structure of the class according to the attributes of the class, and generate the metadata file of the class according to the extended metadata structure , and then package the metadata file and the content file of the audio-visual resource in this class to generate a total file, so as to realize the optimization of the metadata of the audio-visual resource in Internet TV.

[0083] In order to enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0084] The flow process of the inventive method is as figure 1 Shown:

[0085] Step 110: Define audio-video resources with common attributes as a class of VOD.

[0086] Among the existing massive on-demand resources, many audio-visual resources have ...

Abstract

The present invention discloses a method and a system for optimizing audio and video resource metadata in a network television. In the method, at least one audio and video resource as a class for program ordering, which has common attributes, is defined, in the class, an ordinary metadata structure formed by the common attributes and a special metadata structure formed by special attributes are combined to form the metadata structure of the class, the metadata file of the class is generated according to the metadata structure, the metadata file and the audio and video resource file in the class are packaged to produce a general file which is then sent to an outside resource management system. The system of the present invention includes a class definition module, a metadata structure extension module and a file generation module. The method and the system of the present invention can avoid a large quantity of redundant data generated in the metadata file, reduce the workload when a terminal resource provider enters information, and also increase the efficiency of network transmission and the information downloading speed of a set-top box at the same time.

Description

technical field [0001] The invention relates to the field of network communication, in particular to a method and system for optimizing audio-video resource metadata in network television. Background technique [0002] IPTV (Internet Protocol Television) refers to a TV broadcast service based on the IP protocol. The service uses a TV or personal computer as a display terminal to provide end users with broadband services such as digital broadcast TV, video services, information services, interactive communities, interactive leisure and entertainment, and e-commerce through broadband networks. The main features of IPTV are interactivity and real-time performance. Its system structure mainly includes subsystems such as video on demand (VOD) service, program editing, storage, authentication and billing, and the main content stored and transmitted is streaming media files. The user terminal can be an IP set-top box plus a TV, or a personal computer. [0003] In the existing IPT...
