Embodiment Construction

[0019] Certain terms are used throughout the description and claims to refer to specific components. Manufacturers may refer to components by different names, as those skilled in the art appreciate. This document does not intend to distinguish between parts that differ in name but have the same function. In the claims and the following description, the terms "comprises" and "comprises" are used in an open manner, and thus should be interpreted to mean "including, but not limited to". Also, the term "coupled" is intended to mean an indirect or direct electrical connection. Thus, if a device couples to another device, that connection may be through a direct electrical connection or through an indirect electrical connection via other devices and connections.

[0020] The present invention proposes to apply data compression to the display data, and then send the compressed display data through the display interface. Since the data size / data rate of the compressed display data i...

Abstract

A data processing apparatus has a compressor and an output interface. The compressor performs compression upon an input display data to generate a compressed display data, wherein an error-resilient coding tool is involved in the compression. The output interface packs an output display data derived from the compressed display data into an output bitstream, and outputs the output bitstream via a display interface, wherein the display interface is one of a display serial interface (DSI) standardized by a Mobile Industry Processor Interface (MIPI) and an embedded display port (eDP) standardized by a Video Electronics Standards Association (VESA).

Description

[0001] [Cross-reference to related applications] [0002] This application claims priority to US Provisional Patent Application Serial No. 61 / 954,667 filed March 18, 2014, which is hereby incorporated by reference. 【Technical field】 [0003] Embodiments of the disclosed invention relate to sending display data through a display interface, and more particularly, to a data processing apparatus and related data processing method that perform display data compression / decompression with color format conversion. 【Background technique】 [0004] A display interface is located between the first chip and the second chip to send display data from the first chip to the second chip for further processing. For example, the first chip may be a main application processor, and the second chip may be a driving integrated circuit (Integrated Circuit, IC for short). The display data may include image data, video data, graphics data and / or on screen display (OSD) data. Furthermore, the display...
