Publication number: 20130250179Abstract: An asymmetric link configured to operate conflicting video source devices. The asymmetric link transmits, over a first direction, a first uncompressed video stream from a first source device to a first sink device. A switch coupled to the asymmetric link receives a request to transmit a second uncompressed video stream from a second source device to a second sink device over the opposite direction of the asymmetric link. The switch locates an accessible rendering device able to receive compressed video from the second source device and to transmit a third uncompressed video stream to the second sink device without flipping the first direction of the asymmetric link.Type: ApplicationFiled: September 20, 2012Publication date: September 26, 2013Applicant: VALENS SEMICONDUCTOR LTD.Inventor: Eyran Lida

Patent number: 8502923Abstract: A method for switching a channel of an image display device and an apparatus adopting the method are disclosed. The method for switching a channel includes switching a currently displayed channel to a major channel, which is adjacent to the currently displayed channel, if a channel switch command is input using a first direction key, and switching the currently displayed channel to a minor channel, which is adjacent to the currently displayed channel, if a channel switch command is input using a second direction key. Accordingly, a user can switch to a desired channel, thereby increasing user convenience, and a list of minor channels pertaining to a current channel is displayed, so that all channels provided by the broadcasting station of the current channel can be identified.Type: GrantFiled: April 26, 2007Date of Patent: August 6, 2013Assignee: Samsung Electronics Co., Ltd.Inventor: Ki-joo Hong
