Device and method for extracting audio/video content information

Abstract

The invention provides an audio / video processing device and an audio / video processing method. The audio / video processing device comprises a receiving unit, a decoding unit, a user interface unit, an information extracting unit and an information storage unit, wherein the receiving unit receives signals and outputs transmission streams; the decoding unit decodes the output transmission streams; the user interface unit receives a determined content output by users; the information extracting unit extracts a prescribed content; and the information storage unit stores the prescribed content, wherein the determined content includes a determined video content or determined audio content, and the alternative one is determined by an audio / video contrasting relation table. The information extracting unit comprises an audio identification unit, a video identification unit and an information matching unit, wherein the audio identification unit identifies the determined audio content from audio steams from the decoding unit; the video identification unit identifies the determined video content from video steams from the decoding unit; the information matching unit determines if an identification result of the audio identification unit is matched with an identification result of the video identification unit, and when the identification result of the audio identification unit is matched with the identification result of the video identification unit, the information matching unit records the prescribed content which corresponds to the determined video content or the determined audio consent in the information storage unit.

Description

technical field [0001] The invention relates to an audio and video information extraction device and method in the field of broadcasting and television, and an audio and video processing device including the device, in particular to a device and method capable of intelligently extracting relevant information from audio and video program streams. Background technique [0002] With the development of audio and video technology and related technologies in the field of radio and television, new broadcast formats provide greater data capacity.
