摘要:
In an interlaced picture having a mixture of field structure macroblocks and frame structure macroblocks, a coding distortion removal method removes coding distortion in blocks composing the macroblock. The method removes a coding distortion in a block block which is included in a macroblock of a frame structure, and which is not adjacent to a boundary of a macroblock of field structure. A coding distortion in a block which is included in a macroblock of the field structure, and which is not adjacent to a boundary of a macroblock of the frame structure is then removed, and a coding distortion in a block which is adjacent to both a macroblock of the frame structure and a macroblock of the field structure is removed.

Mosaic-shaped block noise occurs when a compressed video signal is reproduced. This block noise is removed, but removing block noise from every block using a deblocking filter imposes a significant load on the deblocking filter. This load is therefore reduced by determining whether coding distortion removal (deblocking) is necessary, and applying a deblocking filter only when needed.

A playback apparatus (100) and corresponding method for playing back images. The apparatus comprising a controller (110) configured for executing the steps of: recognizing an object in an image being played back (320); obtaining a keyword (410) associated to the recognized object (340); and—searching for information based on the keyword (370).
摘要:
The invention relates to a playback device for playback of a video content and of a file obtained separately from the video content. The invention is for a system wherein a file to be played with a movie is obtained from an uncontrolled source such as the Internet. Obtaining a file from such a source creates a number of issues due to the lack of control. The file obtained may not correspond to the intended movie or to the intended language and may not be synchronized with the movie. The invention proposes: 1) to verify that the separately obtained file corresponds to the movie; 2) if the separately obtained file corresponds to the movie, to determine whether it is synchronized with the movie; 3) if the separately obtained file is not synchronized with the movie, to synchronize it. The correspondence can be verified based on language, key phrases relating to the movie, or timing.
