Problems solved by technology

Existing video editing systems are all designed for ordinary TV programs. Although they can also be competent for editing some stereoscopic TV programs, they often feel difficult for some slightly complicated situations during the editing process, and some complex special effects image rendering At the same time, due to the large amount of calculations for rendering, it is even impossible to achieve, so that it can only be replaced by some simplified means, which reduces the enjoyment of the broadcast and affects the quality of the program.

Embodiment 1

[0031] This embodiment is a method for editing stereoscopic TV signals based on cluster rendering. The schematic diagram of the system used in the method is as figure 1 shown. figure 1 The computing and rendering server cluster in the figure only shows 3 servers, but there can actually be 4, 5, 6, or even more, and there can be 2, 3, 4, or even more front-end workstations.

[0032] The steps of the method described in this embodiment are as follows, and the flow chart is as follows figure 2 Shown:

[0033] The steps of preparing for the acquisition and storage of stereoscopic TV signals: it is used to acquire and save the various video signals of the stereoscopic camera at the same time, and mark the time code of each video frame according to a unified time standard for each video of the acquisition. The collected original video files are stored in the storage server in a unified manner.

Embodiment 2

[0065] This embodiment is an improvement of the first embodiment, and is a refinement of the steps of the first embodiment regarding result transmission. In the step of result transmission described in this embodiment, every time the computing and rendering server completes a frame of video image, it transmits it to the front-end workstation in time, and the front-end workstation compares the computing result and the multi-channel rendered video image information for each of the same time code frame After the video is decoded, corrected and processed in time, it can be sent for display, while the 3D TV video picture information decoded, corrected and processed in advance will be cached in the local memory of the front-end workstation, and sent to the 3D display device for display at an appropriate time come out.

Embodiment 3

[0067]This embodiment is an improvement of the first embodiment, and is a refinement of the steps of the first embodiment regarding result transmission. In the step of result transmission described in this embodiment, the front-end workstation judges whether the current network speed and bandwidth meet the transmission requirements of the uncompressed video images of each 3D TV. Ask for uncompressed video data; if the network speed and bandwidth cannot meet the transmission requirements of uncompressed video images, the front-end workstation will request compressed video data from the computing rendering server currently responsible for decoding and processing the image video of this channel, and will receive the received video data Decode the compressed video data.

Abstract

The invention relates to a stereotelevision signal editing method based on cluster rendering, comprising collecting and storing stereotelevision signals; preparing a calculation environment; initializing stereotelevision signal processing task operation; preprocessing a video frame to be edited; distributing tasks; rendering calculation; outputting results; performing displaying; and completing the tasks. The method employs a task resource scheduling server to comprehensively utilize and schedule calculation rendering servers and front work stations to render and process stereo video images. According to idle condition of each calculation rendering server, the task resource scheduling server reasonably distributes rendering tasks, fully utilizes the effective resource of each calculation rendering server, rapidly completes rendering tasks in real time, and effectively avoids jamming in the editing process of stereotelevision programs.

Description

technical field [0001] The invention relates to a stereoscopic TV signal editing method based on cluster rendering, is a computer video processing method, and is a video editing processing method for a TV station network. Background technique [0002] In the production process of stereoscopic TV programs, since the stereoscopic TV signals are shot by multiple cameras, the number of cameras is more than double that of ordinary TV programs, and some complex editing needs a lot of calculations to be realized. The video editing system requires Process multiple signals at the same time in a short time to meet the requirements of real-time broadcasting. Existing video editing systems are all designed for ordinary TV programs. Although they can also be competent for editing some stereoscopic TV programs, they often feel difficult for some slightly complicated situations during the editing process, and some complex special effects image rendering Sometimes, due to the large amount ...
