Embodiment Construction

[0025] In the embodiment of the present invention, after sending a control command to the stream controller, the video stream information is detected in real time, and the state of the current video stream is determined. When the state of the current video stream is consistent with the state required after the video stream control operation, Confirm that the control operation is complete. It can be seen that the embodiment of the present invention realizes the real-time detection of the video stream, and timely discovers the change of the video stream state, thereby improving the accuracy of controlling the video stream.

[0026] see figure 1 , the control device in this embodiment includes an image input device 101 , a stream controller 102 , an operating mode module 103 , a state detection module 104 and a memory 105 .

[0027] The memory 105 is used to store video stream data. The video stream data includes video stream valid data and video stream non-valid data. The vid...

Abstract

The invention discloses a method for controlling a video stream, which is used for enhancing the accuracy of controlling the video stream. The method comprises the following steps of: sending a control command to a stream controller, and indicating the stream controller to carry out control operation on the video stream; determining a current video stream state according to video stream information; and when the current video stream state is consistent with a needed state of the video stream after the control operation, determining that the control operation is finished. The invention also discloses a device for realizing the method.

Description

technical field [0001] The invention relates to the fields of computer and video, in particular to a method and device for controlling video stream. Background technique [0002] With the development of digital technology, digital cameras and digital video cameras have become popular digital products, and everyone will carry a digital product whether they need to work or travel. In a blink of an eye, the development and growth of digital cameras has been almost ten years. It is hard to imagine how many hardships we have experienced from scratch, from having to being refined, from 300,000 pixels to the current 30 million pixels. In the civilian digital camera market, 2007 may be a year of diversified development. Digital cameras also have the function of video recording, and digital video cameras also have the function of taking pictures and playing MP3 and MP4. [0003] Different functions of digital products are usually realized in different working modes. Some working m...
