Problems solved by technology

When a display supports a higher display resolution, a 2D / 3D display with a higher resolution can be realized, therefore, the display data transmitted through the display interface will have a larger data size / data transfer rate, which inevitably increases the power consumption of the display interface

Embodiment Construction

[0035] Certain terms are used in the specification and claims to refer to particular components. It should be understood by those skilled in the art that hardware manufacturers may refer to the same component by different nouns. The present specification and claims do not use the difference in name as a way to distinguish components, but use the difference in function of the components as a criterion for distinguishing. The "comprising" mentioned throughout the specification and claims is an open-ended term, and should be interpreted as "including but not limited to". In addition, the word "coupled" herein includes any direct and indirect electrical connection means. Therefore, if the first device is described as being coupled to a second device, it means that the first device can be directly electrically connected to the second device. device, or indirectly electrically connected to the second device through other devices or connecting means.

Abstract

A data processing apparatus has a compressor and an output interface. The compressor generates a compressed display data by compressing a display data according to a compression algorithm. The output interface records indication information in an output bitstream, and outputs the output bitstream via a display interface, wherein the output bitstream is derived from the compressed display data, and the indication information is set in response to the compression algorithm employed by the compressor. Another data processing apparatus has a de-compressor and an input interface. The de-compressor de-compresses a compressed display data derived from an input bitstream. The input interface receives the input bitstream via a display interface, parses indication information included in the input bitstream, and configures the de-compressor to employ a de-compression algorithm as indicated by the indication information.

Description

[0001] cross reference [0002] The present invention requests U.S. Provisional Application No. 61 / 711,319 (filed on October 9, 2012), U.S. Provisional Application No. 61 / 712,949 (filed on October 12, 2012) and U.S. Provisional Application No. 13 / 953,752 ( filing date July 30, 2013), and the entire contents of these applications are incorporated by reference. technical field [0003] Embodiments disclosed in the present invention relate to transmitting / receiving display data through a display interface, especially a data processing device and related data processing method with adaptive selection of compression / decompression algorithms for data transmission through the display interface. Background technique [0004] A display interface between the first chip and the second chip is used to transmit display data from the first chip to the second chip for further processing. For example, the first chip can be a host application processor, and the second chip can be a driver ...
