Abstract

Video playback method and control terminal thereof are provided. The invention receives video data stream, determines if a to-be-decoded frame meets a discard condition according to the time stamp of the to-be-decoded frame, if the discard condition is met, discards the non-reference frame to be decoded in the video data stream, and if the discard condition is not met, decodes the to-be-decoded frame into to-be-output frame; determines if the to-be-output frame meets the discard condition according to the time stamp of the to-be-output frame; if the discard condition is met, discards the to-be-output frame; if the discard condition is not met, outputs the to-be-output frame as output frame, such that the time intervals of the time stamps of the sequentially output frames according to the display order are equal.

A video playback method, comprising:

receiving video data stream;
determining whether a to-be-decoded frame in the video data stream is a non-reference frame that meets a discard condition according to the time stamp of the to-be-decoded frame;
discarding the to-be-decoded frame when the to-be-decoded frame is a non-reference frame that meets the discard condition;
decoding the to-be-decoded frame into a to-be-output frame when the to-be-decoded frame is not a non-reference frame that meets the discard condition;
determining whether the to-be-output frame meets the discard condition according to the time stamp of the to-be-output frame;
discarding the to-be-output frame when the to-be-output frame meets the discard condition;
and
outputting the to-be-output frame as an output frame when the to-be-output frame does not meet the discard condition, such that the time intervals of the time stamps of the sequentially output frames according to the display order are equal.

A control terminal for video playback, comprising:

a receiving unit, receiving video data stream;
a pre-decoding determination unit, determining whether a to-be-decoded frame in the video data stream is a non-reference frame that meets a discard condition according to the time stamp of the to-be-decoded frame, wherein the pre-decoding determination unit discards the to-be-decoded frame when the to-be-decoded frame is a non-reference frame that meets the discard condition;
a decoding unit, decoding the to-be-decoded frame into a to-be-output frame when the to-be-decoded frame is not a non-reference frame that meets the discard condition;
and
a post-decoding determination unit, determining whether the to-be-output frame meets the discard condition according to the time stamp of the to-be-output frame, discarding the to-be-output frame when the to-be-output frame meets the discard condition, and outputting the to-be-output frame as an output frame when the to-be-output frame does not meet the discard condition, such that the time intervals of the time stamps of the sequentially output frames according to the display order are equal.
