Embodiment Construction

[0017] The present invention will be described in detail below with reference to the accompanying drawings.

[0018] The present invention provides a live streaming display control device, which is applied to a network display terminal device. The following description takes software implementation as an example, but the present invention does not exclude other implementations such as hardware or logic devices. like figure 1 As shown, the network display terminal device includes CPU, memory, non-volatile memory and other hardware. The live streaming display control device acts as a virtual device at a logical level, which is run by the CPU. The device includes a queue entry time recording unit, a sending and displaying time calculating unit, and a sending and displaying state updating unit. Please refer to figure 2 specific implementation steps.

[0019] Step 101, after the entry time recording unit acquires a frame of decoded data, stores the frame data in the display bu...

Abstract

The invention provides a live flow sending display control method and device which are applied to network display terminal equipment. The method comprises the steps of obtaining one frame decoding data and storing into a sending display cache queue and recording the queue entering time; selecting one frame data from the queue according to the reading sequence as the current frame, calculating the standard sending display time of the current frame by taking a preset standard delay duration as the time interval based on last frame sending display time, and according to the sending display state of the current frame, determining the sending display time of the current frame by the preset amending duration based on the standard sending display time; updating the sending display state of the next frame according to the frame delay duration and the relation of upper and lower limits of the preset frame delay duration, wherein the delay duration of the current frame is the duration from the queue entering time, to the sending display cache queue, of the current frame to the sending display time. The live flow sending display control method and device solve the problem that the fluency and real time property are not compatible when people watch live video flow and achieve the most balanced state of the real time property and the fluency.

Description

technical field [0001] The present invention relates to the field of video surveillance, and in particular, to a method and device for controlling live streaming display. Background technique [0002] When watching live webcams, you want to see the lowest latency and smoothest live images. However, due to the existence of factors such as front-end encoding delay, network jitter, and back-end decoding delay, if the decoded image is directly sent for display, the human eye will observe the obvious phenomenon of unsmooth live performance. [0003] In order to make the live playback smooth, the general method is to use the buffering mechanism of buffering N-frames to send and display images to smoothly send and display frame image data, so as to achieve the effect of improving the fluency. However, the more data cached, the better the fluency, the greater the delay, and the worse the real-time performance. Therefore, low latency and high fluency are a pair of contradictions, a...
