摘要： A liquid crystal display (LCD) and method of adjusting brightness for the LCD are provided. The LCD includes a light emitter including a plurality of luminescent bodies which are divided into a predetermined number of partial areas, a backlight driver connected to the light emitter to control the brightness of each of the partial areas of the light emitter, and a controller for calculating a representative value for adjusting the brightness of each of the partial areas of the light emitter in accordance with an input image signal and outputting the representative value as a brightness adjustment signal for adjusting the brightness of each of the partial areas to the backlight driver. Thus, the brightness of each of partial areas of a backlight can be adjusted in accordance with the input image signal to improve a contrast ratio. Also, a representative value to be used for adjusting the brightness of each of the partial areas can be lowered by a predetermined ratio to effectively reduce power needed for lighting the backlight. Also, light loss and light gain occurring between neighboring partial areas can be compensated to improve the contrast ratio, and image artifacts can be reduced.

摘要： A method, apparatus and system for pre-authenticating ports is disclosed. In one embodiment, an active port facilitating communication of media content between a transmitting device and a receiving device is identified, while the active port are associated with a first High-Definition Content Protection (HDCP) engine. Then, inactive ports that are in idle mode serving as backup ports to the active port are identified, while the inactive ports are associated with a second HDCP engine. Pre-authentication of each of the inactive ports is performed so the pre-authenticated inactive ports can subsequently replace the active port if a port switch is performed.

摘要： A current sense amplifier may include one or more clamping circuits coupled between differential output nodes of the amplifier. The clamping circuits may be enabled during at least a portion of the time that the sense amplifier is sensing the state of a memory cell coupled to a differential input of the sense amplifier. The clamping circuits may be disabled during the time that the sense amplifier is sensing the state of a memory cell at different times in a staggered manner. The clamping circuits may be effecting in making the current sense amplifier less sensitive to noise signals.

摘要： A mechanism for memory reduction in picture-in-picture video generation is disclosed. A method of embodiments of the invention includes receiving, from a transmitting device, a plurality of video streams at a receiving device coupled to the transmitting device, wherein a first video stream of the plurality of video streams is designated to be displayed as a main video and one or more other video streams of the plurality of video streams are designated to be displayed as one or more sub videos to the main video. The method further includes transforming the one or more other video streams into the one or more sub videos, temporarily holding the one or more sub videos in a compressed frame buffer, and merging, via pixel replacement, the main video and the one or more sub videos into a final video image capable of being displayed on a single screen utilizing a display device, wherein pixel replacement is performed such that the one or more sub videos occupy one or more sections of pixels of screen space pixels occupied by the main video.
