Abstract
(EN)
Disclosed in the present invention are a multi-stream video processing apparatus and a method, the method including: multiple video streams generated by a front-stage circuit, including a primary video stream and at least one sub-video stream, a resolution of the primary video stream being higher than a resolution of the sub-video stream; during a video image processing time interval, temporarily storing an Nth sub-video image from the front-stage circuit in a current sub-video temporary storage block of a memory module, and temporarily storing an Nth primary video image in a primary video temporary storage block of the memory module; during a first sub-interval of the video image processing time interval, a back-stage circuit reading a sub-video image N-1 from the current sub-video temporary storage block of the memory module, so as to perform processing; in a second sub-interval of the video image processing time interval, the back-stage circuit reading the Nth primary video image, so as to perform processing.
