Embodiment Construction

[0044] In the following description, specific details such as specific system structures and technologies are presented for the purpose of illustration rather than limitation, so as to thoroughly understand the embodiments of the present invention. It will be apparent, however, to one skilled in the art that the invention may be practiced in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.

[0045] In order to illustrate the technical solutions of the present invention, specific examples are used below to illustrate.

[0046] Such as figure 1Shown is a schematic diagram of the network system structure of NVR (English full name is Network Video Recorder, Chinese full name is Network Video Recorder) network system. Factors causing NVR network delay include: imaging delay (CCD imaging p...

Abstract

The invention is applicable to the field of video preview and provides a video preview method which comprises the following steps: acquiring the resolution of a code stream of a video preview channel; according to the resolution of the code stream of the video preview channel, calculating decoding resource consumption corresponding to the video preview channel; when the code stream of the video preview channel is decoded, judging whether the decoding resource consumption corresponding to the code stream is greater than a system residual resource amount or not; if the decoding resource consumption corresponding to the code stream is greater than the system residual resource amount, judging according to a next code stream of the code stream of the current video preview channel. Therefore, limited decoding resources can be reasonably allocated, and the problem that too large preview delay is caused as bottom layer decoding resource allocation is failed since the resolution of a code stream is too large is avoided.

Description

technical field [0001] The invention belongs to the field of video preview, in particular to a video preview method, device and equipment. Background technique [0002] NVR (Network Video Recorder) is a network storage device. Its main function is to receive digital video streams transmitted by IPC (IP Camera) devices through the network, and provide storage, management, playback and preview of multiple streams. Features. In the high-definition network video monitoring platform, due to the large amount of data and the decoding is limited by hardware resources and other factors, the bandwidth occupation depends on the compression level of each video image, frame size (that is, the resolution corresponding to the frame), and frame rate. And the bit rate, and the frame size will affect the allocation of decoding resources. Therefore, under limited bandwidth and hardware decoding resources, excessive frame size and frame rate will lead to poor preview experience. [0003] The ...
