Publication number: 20170221440Abstract: The present invention provides a display apparatus, including: a display panel circuit which includes a panel load line and performs a scanning display operation; and a panel driving circuit. The panel driving circuit determines at least a test phase and a scanning display phase according to a display control signal generated by a timing control circuit, wherein the test phase is a partial time period when the panel driving circuit does not perform the scanning display operation. The panel driving circuit generates a test driving signal on the panel load line, and detects an electronic characteristic of the display panel circuit so as to determine a failure item thereof during the test phase according to a pre-determined test instruction. The panel driving circuit generates a display driving signal on the panel load line for the scanning display operation according to the display control signal during the scanning display phase.Type: ApplicationFiled: July 22, 2016Publication date: August 3, 2017Inventors: Chien-Chung Chen, Hsing--Shen Huang

Publication number: 20170125022Abstract: The present document relates to audio signal processing in general, and to the concealment of artifacts that results from loss of audio packets during audio transmission over a packet-switched network, in particular. A method (200) for concealing one or more consecutive lost packets (412, 413) is described. A lost packet (412) is a packet which is deemed to be lost by a transform-based audio decoder. Each of the one or more lost packets (412, 413) comprises a set of transform coefficients (313). A set of transform coefficients (313) is used by the transform-based audio decoder to generate a corresponding frame (412, 413) of a time domain audio signal. The method (200) comprises determining (205) for a current lost packet (412) of the one or more lost packets (412, 413) a number of preceding lost packets from the one or more lost packets (313); wherein the determined number is referred to as a loss position.Type: ApplicationFiled: December 5, 2016Publication date: May 4, 2017Applicant: Dolby Laboratories Licensing CorporationInventors: Shen HUANG, Xuejing SUN

Patent number: 9525845Abstract: Embodiments of client device and method for audio or video conferencing are described. An embodiment includes an offset detecting unit, a configuring unit, an estimator and an output unit. The offset detecting unit detects an offset of speech input to the client device. The configuring unit determines a voice latency from the client device to every far end. The estimator estimates a time when a user at the far end perceives the offset based on the voice latency. The output unit outputs a perceivable signal indicating that a user at the far end perceives the offset based on the time estimated for the far end. The perceivable signal is helpful to avoid collision between parties.Type: GrantFiled: September 27, 2013Date of Patent: December 20, 2016Assignees: Dobly Laboratories Licensing Corporation, Dobly International ABInventors: Dong Shi, Xuejing Sun, Kai Li, Shen Huang, Harald Mundt, Heiko Purnhagen, Glenn Dickins

Publication number: 20160359943Abstract: A service request for communication services for communication clients is received. In response, a communication service network is set up to support the communication services. Routing metadata is generated for each of the communication clients. The routing metadata is to be used by each of the communication clients for sharing service quality information with a respective peer communication client over a light-weight peer-to-peer (P2P) network. The routing metadata is downloaded to each of the communication clients. A communication client may exchange service signaling packets or service data packets over the communication service network. When the communication client determines that there is a problematic region in a bitstream received from the communication server, the communication client can request a peer communication client for a service quality information portion related to the problematic region.Type: ApplicationFiled: June 1, 2016Publication date: December 8, 2016Applicant: Dolby Laboratories Licensing CorporationInventors: Shen HUANG, Doh-Suk KIM, Xuejing SUN
