Problems solved by technology

[0004] The existing solution requires the assistance of hardware instruments, and the image acquisition frequency of the instrument needs to be very high, and the video images of different resolutions need to be adapted one by one. In addition, the freeze characteristic images of different set-top box terminals are different, which leads to the need for each Carton feature image adaptation for a new set-top box

Embodiment 1

[0042] The embodiment of the present invention provides a method for judging video stuttering in the output video of an Internet TV set-top box, especially applicable to the Android system, see figure 1 , the method can include:

[0043] Step S11, simulating the smoothness of the video output of the Internet TV set-top box, and collecting the first CPU occupancy rate when the video output software is running at the same time intervals within the preset time period.

[0044] In this embodiment, the Android system provides a video decoding solution for Mediaplayer developers to use. Among them, the Internet TV set-top boxes based on the Android system all use the Mediaplayer solution to realize video playback. Monitor CPU usage when Mediaplayer is running. For example: when simulating the smooth video output of the Internet TV set-top box (that is, normal playback and no freeze), the first CPU usage rate when Mediaplayer is running is collected every N milliseconds (N is a posi...

Embodiment 2

[0060] The embodiment of the present invention provides a device for judging video stutter output from an Internet TV set-top box, which realizes the method described in Embodiment 1, see figure 2 , the device may include: a collection module 100 and a judging module 200 .

[0061] The acquisition module 100 is used to simulate the smoothness of the video output of the Internet TV set-top box, and collect the first CPU occupancy rate when the video output software is running at the same time interval in the preset time period.

[0062] In this embodiment, the Android system provides a video decoding solution for Mediaplayer developers to use. Among them, the Internet TV set-top boxes based on the Android system all use the Mediaplayer solution to realize video playback. Monitor CPU usage when Mediaplayer is running. For example: when simulating the smooth video output of the Internet TV set-top box (that is, normal playback and no freeze), the first CPU usage rate when Media...

Abstract

The invention discloses a lagging judgment method and device for Internet television set top box to output video l. The method comprises the following steps: simulating the video output fluency of anInternet television set top box, and acquiring a first CPU occupancy rate when video output software runs at the same time interval within a preset time period; simulating the video output jamming condition of the set top box of the Internet television, and acquiring a second CPU occupancy rate when the video output software runs at the same time interval within a preset time period; acquiring a third CPU occupancy rate when the video output software in the Internet television set top box runs at the same time interval within the to-be-tested time period; and judging whether the video output of the Internet television set top box is jammed or not in the to-be-detected time period according to a preset judgment condition and the acquired CPU occupancy rate. The judgment method provided by the invention can continuously and accurately monitor the video jamming condition of the set top box, is not influenced and judged by variable factors such as resolution or jamming feature images, andis high in judgment precision.

Description

technical field [0001] The present invention relates to the technical field of video freeze judgment, and in particular to a method and device for judging video freeze output from an Internet TV set-top box. Background technique [0002] With the rapid development of Internet technology, digital TV is becoming more and more popular. The smoothness of the video output from the Internet TV set-top box has an important impact on the effect of digital TV. TV playback effect. [0003] The existing freeze judgment method is to use external hardware instruments to compare the video images output by the set-top box frame by frame to find the image characteristics when the video freezes: this method requires external instruments to collect the video images output by the set-top box for regular Scan, and then compare the collected images before and after, calculate the difference between the two images, and find the stuck characteristic graphics in the image, such as the loading circ...
