Problems solved by technology

Although there are still images that have not been read in the memory at this time, since the first configuration table is re-established, it is equivalent to discarding the information of these unread images, so it is impossible to read from the first configuration table when playing. Read the information of these unread images, so these unread images will be skipped, and only black screens can be replaced
That is to say, in the known technology, when the image resolution changes, one or several images will be presented as black screens during image playback, and seamless switching cannot be achieved, thereby affecting user experience.

Embodiment Construction

[0030] Please refer to figure 2 , which is a flowchart of an embodiment of the method for writing an image into a memory according to the present invention.

[0031] After the receiving end receives the audio-visual stream and performs demultiplexing to separate the image data, it first proceeds to step S200 to establish a first configuration table according to the first resolution of the images included in the image data. The first configuration table is related to the usage configuration of the memory, which plans the memory into a plurality of first buffers, and these first buffers are planned according to the first resolution, and the size of each first buffer is enough to write a First resolution image.

[0032] When the receiving end continues to receive images with the first resolution, the images are written into the first buffers of the memory according to the first configuration table. At the same time, record the first buffer area where each image is written into...

Abstract

The present invention provides a method for writing an image into a memory, and the method includes the following steps: establishing a first configuration table according to a first resolution of a first image, which plans the memory into a plurality of first buffer areas; establishing a second configuration table according to a second resolution of a second image, which plans the memory into a plurality of second buffers, and the second resolution is different from the first resolution; and according to the first The configuration table and the second configuration table determine the location where the second image is written into the memory.

Description

technical field [0001] The present invention relates to a method for writing images into a memory, in particular to a method for writing images of video and audio streams into a memory. Background technique [0002] With the development of Internet and wireless transmission technology, video streaming has become a new network multimedia transmission method in recent years. Audio-visual streaming is to encode multimedia data and transmit it from the sending end to the receiving end through the Internet or wireless transmission, and the receiving end downloads, decodes and plays it. The feature of audio-visual streaming is that it does not need to download the entire multimedia data and store it at the receiving end, but uses the memory buffer to store and process part of the received multimedia data, and releases the memory directly after the part of the multimedia is played The buffer space is used for subsequent downloading of multimedia data. [0003] However, for the hi...
