Embodiment Construction

[0013] In general, the present invention relates to techniques for determining Lagrangian parameters in the context of video compression techniques such as Display Stream Compression (DSC). Although certain embodiments are described herein in the context of the DSC standard, those skilled in the art will appreciate that the systems and methods disclosed herein may be applicable to any suitable video coding standard. For example, embodiments disclosed herein may apply to one or more of the following standards: International Telecommunication Union (ITU) Telecommunication Standardization Sector (ITU-T) H.261, International Organization for Standardization / International Electrotechnical Commission (ISO / IEC) Animation Experts Group-1 (MPEG-1)Visual, ITU-T H.262 or ISO / IEC MPEG-2Visual, ITU-T H.263, ISO / IEC MPEG-4Visual, ITU-T H.264 (also known as For ISO / IEC MPEG-4AVC) and High Efficiency Video Coding (HEVC), and extensions to such standards. Furthermore, the techniques describe...

Abstract

According to certain aspects, an apparatus for coding video data includes a memory for storing the video data and a processor. The memory includes a buffer. The processor is configured to receive the video data to be coded. The processor is further configured to determine a Lagrangian parameter for a coding mode based at least in part on a bit rate of the coding mode and a fullness of the buffer.

Description

technical field [0001] The present invention relates to the field of video coding and compression, and in particular, to video compression for transmission over a display link, eg, Display Stream Compression (DSC). Background technique [0002] Description of related technologies [0003] Digital video capabilities can be incorporated into a wide range of displays, including digital televisions, personal digital assistants (PDAs), laptop computers, desktop monitors, digital cameras, digital recording devices, digital media players, video game devices, Video game consoles, cellular or satellite radiotelephones, video teleconferencing devices and the like. Display Link is used to connect a display to an appropriate source device. The bandwidth requirement of the display link is directly proportional to the resolution of the display, and therefore, a high resolution display requires a large bandwidth display link. Some display links do not have the bandwidth to support high...
