Publication number: 20150110197Abstract: A method for generating a prediction block in Advanced Motion Vector Prediction (AMVP) mode to reconstruct a prediction-coded video signal using a motion vector approximate to original motion information. An AMVP candidate list is generated using effective spatial and temporal AMVP candidates for a current Prediction Unit (PU). If the number of the effective AMVP candidates is smaller than a predetermined value, a motion vector having a predetermined value as a candidate to the AMVP candidate list. Then a motion vector corresponding to an AMVP index of the current PU from among motion vectors included in the AMVP candidate list is determined to be a motion vector predictor of the current PU.Type: ApplicationFiled: December 30, 2014Publication date: April 23, 2015Applicant: IBEX PT HOLDINGS CO., LTD.Inventors: Kwangje KIM, Hyunoh OH

Patent number: 8855209Abstract: Disclosed is an apparatus for decoding motion information in merge mode for reconstructing a moving picture signal coded at a low data rate while maintaining a high quality of an image. The apparatus for decoding motion information in merge mode discloses the position of a merge mode candidate and the configuration of a candidate in order to predict motion information in merge mode efficiently. Furthermore, a merge candidate indicated by the merge index of a current block can be efficiently reconstructed irrespective of a network environment by adaptively generating a merge candidate based on the number of valid merge candidate.Type: GrantFiled: November 26, 2013Date of Patent: October 7, 2014Assignee: Ibex PT Holdings Co., Ltd.Inventors: Kwangje Kim, Hyunoh Oh

Patent number: 8630650Abstract: A method for operating a femtocell in a wireless communication system comprises the steps of: triggering the switching from the operation mode for providing a service to closed subscriber group (CSG) terminals which belong to a specific terminal group and to non-CSG terminals which do not belong to the specific terminal group, to the operation mode for providing the service only to said CSG terminals; and commanding said non-CSG terminals to change the operation mode, and carrying out a handover. The method of the present invention improves efficiency of femtocell operation, and reduces restrictions on terminals disposed in the vicinity of the femtocell. The method of the present invention can utilize the unused frequency range of the femtocell, thereby providing a service with a high data ratio.Type: GrantFiled: December 17, 2009Date of Patent: January 14, 2014Assignee: Ibex PT Holdings Co., Ltd.Inventor: Yongseok Lee

Publication number: 20130128961Abstract: A video coding method for encoding a video signal at a low data rate with high video quality is disclosed. To minimize the number of bits required for a residual signal, invalid reference pixels adjacent to a current block are generated using at least one reconstructed valid reference pixel adjacent to the current block. After valid reference pixels adjacent to the current block and the generated reference pixels are filtered, the intra-prediction mode of the current block is determined. Therefore, since a reference block most approximate to the current block is generated, the amount of data needed for the residual block of the current block can be minimized.Type: ApplicationFiled: January 16, 2013Publication date: May 23, 2013Applicant: IBEX PT HOLDINGS CO., LTD.Inventor: IBEX PT HOLDINGS CO., LTD.
