Problems solved by technology

[0003] In the prior art, when decoding a high-resolution UI material, the acquired UI material is stored in the memory, and the UI material in the memory is extracted and processed to generate a bitmap file, but due to the resolution of the UI material If it is too high, the amount of data to be extracted and processed will increase, resulting in a decrease in decoding speed and low efficiency.
At present, the decoding processing speed is often increased by expanding the memory and improving the CPU performance, for example: using ultra-high-definition TV chips for decoding processing, but this method will inevitably lead to an increase in the cost of ultra-high-definition TV

Embodiment Construction

[0044] figure 1 It is a schematic flowchart of an image decoding method provided by an embodiment of the present invention. The method provided by this embodiment can be executed by an ultra-high-definition television, such as figure 1 shown, including:

[0045] 101. Acquire a UI material, and acquire a coverage of a display area of ​​the UI material on a TV screen.

[0046] Wherein, there is at least one UI material.

[0047]When receiving the user interface display request input by the user, the UHD TV downloads the corresponding UI material from the server according to the user interface display request, and downloads the UI material from the server or obtains the content of the UI material on the TV screen from the memory of the UHD TV. Display the coverage of the area, and the specific coverage can be represented by size, area, etc. The UI material is stored in the memory of the ultra-high-definition television, and the UI material can be maintained by using the task q...

Abstract

The invention provides an image decoding method and an image decoding device. The image decoding method includes acquiring a UI (user interface) material and the coverage of display area of the UI material in a television screen; according to the number of pixels of the UI material and the number of pixels of the display area within the coverage, compressing the UI material; extracting the compressed UI material to acquire a bitmap file to complete the decoding process. The UI material is compressed before being extracted, and the number of the pixels of the UI material is reduced, so that extraction speed is increased, decoding efficiency is further improved, and the technical problem of low decoding efficiency in the prior art is solved.

Description

technical field [0001] The present invention relates to display technology, in particular to an image decoding method and device. Background technique [0002] With the continuous development of display technology, the resolution of TV has also increased. The current UHD TV can have a resolution of 3840×2160P or 7680×4320P. However, the resolution of traditional TV is only 720P or 1080P. Therefore, when traditional TV displays the user interface (UI), it obtains the lower-resolution UI material and the display area of ​​the UI material on the TV screen, and decodes it sequentially. 1. Obtain a user interface with a lower resolution after rendering processing, wherein the UI material is a static image. However, if the above-mentioned UI material is decoded and rendered in an ultra-high-definition television, and when the user interface obtained after decoding and rendering is displayed on an ultra-high-definition television, the user interface may not match the resolution o...
