20130124749 | APPARATUS AND METHOD FOR PROVIDING STREAMING CONTENTS - A method and apparatus for an adaptive Hypertext Transfer Protocol (HTTP) streaming service using metadata of content are provided. The metadata may include a minBufferTime attribute indicating a minimum amount of initially buffered media content. A terminal may receive content from a server before playback of the content, and may buffer the content by at least the minimum amount. The metadata may include a range attribute that designates a range of a target indicated by a Uniform Resource Locator (URL). The terminal may receive bytes designated by the range attribute from the URL, and may play back the content using the received bytes. | 05-16-2013 |
20130166771 | APPARATUS AND METHOD FOR PROVIDING STREAMING CONTENT - A method and apparatus for an adaptive Hypertext Transfer Protocol (HTTP) streaming service using metadata of content are provided. The metadata may include one or more BaseURL elements. Uniform Resource Locators (URLs) of segments forming media may be generated based on the BaseURL elements. Additionally, a URL of a segment may be generated by mapping a BaseURL element among the BaseURL elements to a sourceURL attribute of the segment. Segments indicated by generated URLs may be identical to each other. | 06-27-2013 |
20140122739 | APPARATUS AND METHOD FOR PROVIDING STREAMING CONTENT - A method and apparatus for an adaptive Hypertext Transfer Protocol (HTTP) streaming service using metadata of content are provided. The metadata may include one or more BaseURL elements. Uniform Resource Locators (URLs) of segments forming media may be generated based on the BaseURL elements. Additionally, a URL of a segment may be generated by mapping a BaseURL element among the BaseURL elements to a sourceURL attribute of the segment. Segments indicated by generated URLs may be identical to each other. | 05-01-2014 |
20140126645 | VIDEO ENCODING AND DECODING METHODS AND DEVICE USING SAME - The present invention relates to video encoding/decoding methods and device, wherein the video encoding method according to the invention comprises the following steps: acquiring information of peripheral blocks; setting the information about a current block based on the information of the peripheral blocks; and encoding the current block based on the set information, wherein the current block and the peripheral blocks may be a CU (coding unit). | 05-08-2014 |
20140168364 | METHOD FOR SERVICE COMPATIBILITY-TYPE TRANSMITTING IN DIGITAL BROADCAST - The present invention relates to a method for making 3D stereo digital broadcast service compatible in an MPEG-2-TS format which is used for transmitting and receiving digital TV. To this end, suggested is a method for transmitting detailed information which supports both TS-level multiplexing and ES-level multiplexing when left and right compressed bitstreams are multiplexed, when service compatibility is enabled. | 06-19-2014 |
20140281013 | APPARATUS AND METHOD FOR PROVIDING STREAMING CONTENT - A method and apparatus for an adaptive Hypertext Transfer Protocol (HTTP) streaming service using metadata of media content are provided. The media content may include a sequence of one or more periods. The metadata may include a start time attribute and/or a duration attribute of each of the periods. The metadata may determine a start time of each of the periods, and a start time of each of segments included in each of the periods. A terminal may access segments included in each of the periods, may decode and render data of media content included in the segments, and may play back the media content. | 09-18-2014 |
20140334543 | INTRA PREDICTION MODE ENCODING/DECODING METHOD AND APPARATUS - Disclosed are an intra prediction mode encoding and decoding method, an image decoding device, and an image encoding device. The intra prediction mode decoding method comprises the steps of: deriving most probable modes (MPMs) from surrounding prediction units adjacent to a current prediction unit; and deriving an intra prediction mode of the current prediction unit on the basis of an MPM flag indicating whether an MPM having the same prediction mode as the intra prediction mode of the current prediction unit exists among the derived MPMs. | 11-13-2014 |
20140348241 | METHOD FOR INDUCING PREDICTION MOTION VECTOR AND APPARATUSES USING SAME - Disclosed are a method for inducing a prediction motion vector and an apparatus using the same. An image decoding method can include: a step of determining the information related to a plurality of spatial candidate prediction motion vectors from peripheral predicted blocks of a predicted target block; and a step of determining the information related to temporal candidate prediction motion vectors on the basis of the information related to the plurality of spatial candidate prediction motion vectors. Accordingly, the present invention can reduce complexity and can enhance coding efficiency when inducing the optimum prediction motion vector. | 11-27-2014 |
20150020131 | METHOD FOR TRANSMITTING AND RECEIVING PROGRAM CONFIGURATION INFORMATION FOR SCALABLE ULTRA HIGH DEFINITION VIDEO SERVICE IN HYBRID TRANSMISSION ENVIRONMENT, AND METHOD AND APPARATUS FOR EFFECTIVELY TRANSMITTING SCALAR LAYER INFORMATION - The present invention relates to a method for transmitting and receiving program configuration information for a scalable ultra high definition (UHD) video service under the hybrid transmission environment, and to a method and apparatus for effectively transmitting scalar layer information, and more particularly, the present invention relates to a scheme for inserting group information for the scalable layer of a base layer and an enhancement layer, which form a scalable UHD video, and transmission channel information into a program map table (PMT) or a package configuration table (PCT), and for transmitting same, and to a scalable layer information format for transmitting layer information with a smaller number of bits as possible when a packet header includes scalable layer information. | 01-15-2015 |
