Patent number: 10656433Abstract: It is provided a method for viewing an image that is wider or higher than the display screen, wherein, the image is evenly divided into two portions by using a line passing through centers of larger edges of the image compared to the display screen. The method comprises, at the side of shutter glasses, the steps of receiving a message indicating display of a first portion of the two portions; turning dark of the shutter glasses and turning refraction direction of the shutter glasses towards a first position; turning transparent of the shutter glasses; receiving a message indicating display of a second portion of the two portions; turning dark of the shutter glasses and turning refraction direction of the shutter glasses towards a second position; and turning transparent of the shutter glasses.Type: GrantFiled: December 29, 2012Date of Patent: May 19, 2020Assignee: INTERDIGITAL CE PATENT HOLDINGSInventors: Ren Lei Chen, Jianping Song, Lin Du

Patent number: 8965870Abstract: A user accessing a media service desires to find out more information about the media service by formulating a query, by operation of an input device, where a region of interest of said media service is selected by the user. The query is submitted to other users who are defined by various tiers defined by different types of criteria. The users belonging to such tiers respond back to the query with new information, which is rendered on the media device being used by the user. Such responses are then rendered on the media device of the user. Optionally, a computer assistance mode is operated where keywords are extracted from said communications between users, and such keywords a used to obtain additional results from a resource such as a search engine.Type: GrantFiled: December 23, 2009Date of Patent: February 24, 2015Assignee: Thomson LicensingInventors: Ren Lei Chen, Xiao-jun Ma, Jun Li

Patent number: 8423855Abstract: An adaptive and scalable packet error correction apparatus and method in a wireless multicast network is provided. Each retransmission request from a receiver contains a round number and the number of repairs sent in that round. At each receiver, there are two counters for counting the rounds sent out on the network and the number of repairs that have been required. A receiver on the wireless multicast network listens to the ARQ requests sent by other receivers to update the two counters and determines whether its request should be suppressed or be sent out.Type: GrantFiled: March 6, 2007Date of Patent: April 16, 2013Assignee: Thomson LicensingInventors: Xiao Jun Ma, Huan Qiang Zhang, Ren Lei Chen, Guang Hua Zhou, Jun Li, Charles Chuanming Wang

Patent number: 8193952Abstract: It provides a method for encoding a set of elements by using components defining the structure of each of the set of elements, wherein each element comprises data structure information and at least one data value. The method comprises the steps of: selecting a current element for encoding; determining whether the current element has the same data structure information as a previously encoded element; in the negative, encoding the data structure information of the current element and the at least one data value of the current element; and in the affirmative, encoding the at least one data value of the current element and providing an indication value associated with the current element indicating the current element has the same data structure information as said previously encoded element. The method is used to reduce the encoding redundancy of the structure information.Type: GrantFiled: September 4, 2009Date of Patent: June 5, 2012Assignee: Thomson LicensingInventors: Ren Lei Chen, Guang Hua Zhou, Wen Juan Song, Xiao Jun Ma

Publication number: 20110255458Abstract: A method and apparatus for network transmission in a network system, e.g. WLAN is provided. In the network system, there is a media server for multicasting video stream, a QoS server for obtaining important packets from the media server and reconstructing the obtained important packets into a QoS multicast stream. Then there is an AP for receiving and sending out the multicast video stream to mobile stations directly, and for receiving the QoS multicast stream, re-encapsulating and sending out the stream in multicast-over-unicast way.Type: ApplicationFiled: December 9, 2009Publication date: October 20, 2011Applicant: Thomson LicensingInventors: Ren Lei Chen, Zhi Gang Zhang, Xiao Jun Ma
