Embodiment Construction

[0030] The embodiments of the present invention are described in detail below in conjunction with the accompanying drawings: the present embodiment is implemented on the premise of the technical solution of the present invention, and detailed implementation methods and processes are provided, but the protection scope of the present invention is not limited to the following implementations example.

[0031] In the specific implementation process, users first search for the media content they are interested in from the request, process the metadata, and determine the location of the media by querying the metadata index generated in advance using the same method; then find the video that meets the requirements through the video matching process fragment.

[0032] As shown in FIG. 1 , this embodiment can be divided into the following steps.

[0033] (1) Acquisition of metadata

[0034]The decoder extracts metadata information by PID (Packet Identifier). In the program informati...

Abstract

A time-shift TV set video matching method which combines program content metadata and content analysis belongs to field of electronic information technique. Steps are following: (1) capture of metadata: picking up video program metadata information as package identification symbol, parsing as digital broadcasting operation information rules, and building metadata information index for transferring of inquiring module; (2) video matching in compressed code flow: firstly the video sequence is comminuted into scenes, and selecting key frame within scenes, then picking up movement characteristic and statistic characteristic of key frame to build video structure storeroom and characteristic storeroom, at last searching as inquiring characteristic of user, results which are sequenced for user. The invention makes the best of current technique, adds the metadata high level semanteme characteristic, considers the feedback opinion of user, and increases the precision of result.

Description

technical field [0001] The invention relates to a method in the technical field of telecommunications, in particular to a time-shifting TV program video matching method combined with program content metadata and content analysis. Background technique [0002] The TV service is by far the most popular remote video communication service for users. So far, the TV service basically provides users with one-way services in the form of broadcasting. It has always been a dream for users to obtain the desired video programs anytime and anywhere. . In the past few decades, people in the industry have been devoting themselves to researching interactive video services. Time-shifted TV (Time-shifted TV) function frees users from traditional program schedules. This revolutionary service allows users to pause and rewind programs while watching live TV programs, and can Fast-forward to the moment Live TV is currently broadcasting. Time-shifted TV is achieved by simultaneously storing a c...
