Embodiment Construction

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0024] figure 1 is a schematic diagram of a multi-pass coding system according to an embodiment of the present invention. Such as figure 1 In the system shown, the public buffer pool includes N+1 buffer areas, each of the N channels has 1 reference frame and 1 reconstructed frame, and 1 reference frame occupies one memory unit. Among them, the first channel can determine a buffer area in the public buffer pool, for example: buffer area 2 is determined as...

Abstract

The invention relates to a method and device for distributing memory of coding channels. The method includes the steps of dividing a public cache pool into a plurality of cache areas, determining one of the cache areas in the public cache pool as a memory unit of a first reestablished frame corresponding to the first channel, releasing the memory unit of the first reestablished frame to the public cache pool when determining an original reference frame corresponding to the first channel as a first reference frame, releasing the memory unit of the original reference frame corresponding to the first channel to the public release pool when determining the first reestablished frame as the first reference frame, determining the memory unit released by a previous channel to the public cache pool as the memory unit of a second reestablished frame corresponding to the current channel, releasing the memory unit of the second reestablished frame to the public cache pool when determining the original reference frame corresponding to the current channel as a second reference frame, and releasing the memory unit of the original reference frame corresponding to the current channel to the public cache pool when determining the second reestablished frame as the second reference frame.

Description

technical field [0001] The present invention relates to the technical field of video and image processing, in particular to a method and device for allocating encoding channel memory. Background technique [0002] Compared with traditional analog video recorders, digital video recorders (Digital Video Recorders, referred to as "DVR") use hard disk recording, so they are often called hard disk recorders. It is a computer system for image storage and processing, with functions of long-term video recording, audio recording, remote monitoring and control of image / voice. And its codec system is generally self-compiling and self-decoding, and the number of channels and resolutions of encoding and decoding are relatively fixed. The more codecs, the more memory it takes up, and the higher the memory cost. [0003] The memory occupied by each channel of the current encoding system is independent, mainly because the reference frame and the reconstructed frame occupy more memory. Dur...
