Problems solved by technology

[0004] The purpose of the present invention is to overcome the drawbacks of unsatisfactory video playback in the prior art when high-complexity video sequences or terminal processing capabilities are seriously insufficient, dynamically balance the video decoding pressure of the terminal, improve the smoothness of video playback, and improve user experience. viewing effect; thereby providing a video playback classification processing method

Embodiment Construction

[0027] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0028] The video playback classification processing method of the present invention can be applied to such as figure 1 in the scenario shown. The set-top box sends a video service request to the streaming media server through the broadband network. The streaming media server responds to the request and sends video data to the set-top box through the network. After receiving the video data, the set-top box decodes it and sends it to the TV for display. In this scenario, the network bandwidth can meet the transmission requirements of the video stream, and the network receiving module of the set-top box is also capable of receiving data, but the video decoding capability of the set-top box is insufficient to meet the real-time decoding of all data of the video stream. The video playback hierarchical processing method of the present invention is s...

Abstract

This invention discloses a grading-process method for video play including: a video terminal receives video frames, computes balance between labels of the system time and the display time of the received current frames and determines region where the balance locates, analyzes frame head of the current frames to determine their kinds and classifies the current frames based on the balance and the kinds of the video frames, decodes and displays the current video frames and repeats the above mentioned steps to all video frames received by the terminal.

Description

technical field [0001] The present invention relates to a video playing terminal, in particular to a video playing terminal with limited multimedia processing capability. Background technique [0002] In the process of video playback, such problems are often encountered: the complexity of scenes in different stages of the video sequence is different, and the scenes in some stages are more complicated, and the decoding complexity is higher, which exceeds the processing capability of the terminal. When the decoder After decoding several frames of video images in a complex scene, the current time of the system lags behind the normal display time of video frames. If the frame-by-frame decoding and display is continued, the lag of video image display will be further aggravated, causing users to see The most important thing is the video played at a slow speed; if the complexity of different scenes in the entire video sequence varies greatly, the playback speed will be uneven and t...
