Patent number: 9001275Abstract: HDMI is a digital audio and video communications protocol commonly used in consumer electronics. HDMI is particularly synonymous with high fidelity audio and video. Even though HDMI is a digital communications protocol, the audio quality can be impaired by analog signal impairments and distortions even if there are no digital decoding errors. In particular, the very process by which the audio is converted from Digital (HDMI) to human audible “Analog Audio” can be prone to errors. This occurs when the Digital to Analog Converter (DAC) clock, which is derived from the HDMI TMDS clock or HDMI source, is “distorted” due to its jitter, resulting in erroneous sampling or outputting of vital audio samples, thereby reducing the audio quality of the experience. The present invention reduces the jitter on the TMDS clock, and hence the audio DAC clock, resulting in lower audio distortion.Type: GrantFiled: November 19, 2013Date of Patent: April 7, 2015Inventors: Andrew Joo Kim, David Anthony Stelliga

Patent number: 8681977Abstract: A switcher device comprises a multiplexer coupled in-between at least one input and output cards. The multiplexer detects the presence of an event signal from an activated sink. In response to the detection of the event signal, a processor changes an address of an HDCP receiver from a first address to a second address for enabling the at least one source to authenticate with the input card and enabling the output card to authenticate with the at least one sink for security protocol encryption. In response to the non-detection of the event signal, the processor changes the address of an HDCP receiver from the second address to the first address for disabling the at least one source from initiating a first authentication with the input card, therefore the output card also does not attempt to initiate a second authentication with the at least one sink for security protocol encryption.Type: GrantFiled: February 29, 2012Date of Patent: March 25, 2014Assignee: Crestron Electronics Inc.Inventors: Adolfo Velasco, Daniel Jackson, Yun Mao, Dario Pagano

Patent number: 8648965Abstract: An image signal processor and a method for processing an image signal thereof are disclosed. When the image signal processor executes an automatic chroma gain control (ACC), the image signal processor adjusts a variable rate of ACC gain according to a size of an input color signal to reduce a time for processing the ACC. Even if a difference between the size of the input color signal and the size of a reference color signal is large, the ACC is rapidly processed. As a result, transient phenomenon disappears from a screen.Type: GrantFiled: January 17, 2008Date of Patent: February 11, 2014Assignee: Samsung Electronics Co., Ltd.Inventor: Hye-joung Park
