Patent number: 9167294Abstract: An apparatus for switching television channels and a method thereof are provided. The apparatus for switching television channels includes a tuner unit, at least two video de-multiplexing modules and a switch unit. The tuner unit locks a specific frequency point in a broadcast stream, and the frequency point has at least two program channels. After the tuner unit locks the specific frequency point, each of the video de-multiplexing modules simultaneously and respectively receives the broadcast stream, and performs a de-multiplexing operation and a decoding operation to each of the program channels to generate at least two program streams. The switch unit selects and displays one of the at least two program streams corresponding to a first program channel, and when a second program channel is selected, the switch unit selects and displays the other one of the at least two program streams corresponding to the second program channel.Type: GrantFiled: January 9, 2014Date of Patent: October 20, 2015Assignee: ALi (Zhuhai) CorporationInventors: Wei-Duo Wang, Lei-Ming Xu

Patent number: 8773585Abstract: A method for identifying state of macro block of de-interlacing computing and an image processing apparatus are provided, the method is as follows. A video frame is divided into a plurality of regions, where each of the regions includes a plurality of macro blocks. Then, a basic threshold corresponding to each of the regions is provided according to a position of each of the regions in the video frame, and a first macro block is identified to be a first type macro block or a second type macro block according to the basic threshold corresponding to one of the regions where the first macro block of the macro blocks locates. Then, a corresponding de-interlacing computing step is performed on the first macro block according to an result that the first macro block is identified as the first type macro block or the second type macro block.Type: GrantFiled: January 23, 2013Date of Patent: July 8, 2014Assignee: ALi (Zhuhai) CorporationInventors: Jin-Song Wen, Feng Gao, Jin-Fu Wang
