Embodiment Construction

[0020] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0021] Streaming media playback, the played video data is composed of segments, and the time of each segment varies (ranging from a few seconds or tens of seconds). Each segment is composed of I frame, P frame or B frame, and I frame is a key frame, for example, a segment has dozens of frames of data, the first frame is I frame, followed by P frame and B frame. Decoding of P frames and B frames depends on I frames as reference frames (ie, I frames are reference data). When dragging the video to play or switching to a new playback position (that is, a new time point), if the new playback position i...

Abstract

The invention relates to a streaming media playing method and system. When each segment of the streaming media is played, I frame data of the segment is firstly recorded and saved, and when dragging to or switching to a new playing position of a segment in a high standard definition mode is performed, if the playing position is not an I frame, the recorded and saved I frame data of the segment isfirstly sent to a decoder for decoding and playing and then is decoded and played at the new playing position, and thus the problem of screen blurring can be solved through the mode of providing the Iframe as a reference frame, the viewing experience of users cannot be affected, and good experience can also be brought to the users.

Description

technical field [0001] The present invention relates to the field of media playing, in particular to a streaming media playing method and system. Background technique [0002] At present, during streaming media playback, the videos played are played in order, and the decoders of streaming media terminals (such as computers, PADs, set-top boxes, etc.) are also decoded sequentially from the beginning. During the decoding process, it is necessary to refer to the previous For the decoded video data, some previous video data is used as reference data for decoding. [0003] However, when the network environment is poor, when the user drags the video or switches between high-definition and standard-definition videos, the previously decoded reference data may be lost. As a result, when the subsequent video data is decoded, it cannot be decoded and played without the reference data, resulting in a blurred screen. , which greatly affects the viewing of the user and brings a bad exper...
