20100180626 | REFRIGERATOR - A refrigerator is disclosed, in which shielding members installed on doors installed in a pair at both sides of the front surface of a main body shield a gap between the doors when the doors are closed. The gap between the doors is not exposed when viewed from in front of the refrigerator even when the assembly state of the doors is deformed or the doors are not completely symmetrical with each other, thereby effectively preventing the external appearance of the front part of the refrigerator from being spoiled due to the exposure of the gap between the doors. | 07-22-2010 |

20130016282 | METHOD OF PROVIDING TIMING INFORMATION FOR SYNCHRONIZING MMT PACKET STREAM IN MMT HYBRID DELIVERY SERVICE AND METHOD OF SYNCHRONIZING MMT PACKET STREAM IN MMT HYBRID DELIVERY SERVICEAANM KIM; Sung HeiAACI Daejeon-siAACO KRAAGP KIM; Sung Hei Daejeon-si KRAANM Seo; Kwang DeokAACI Wonju-siAACO KRAAGP Seo; Kwang Deok Wonju-si KRAANM Jung; Tae JunAACI Wonju-siAACO KRAAGP Jung; Tae Jun Wonju-si KRAANM Lee; Chang KyuAACI Daejeon-siAACO KRAAGP Lee; Chang Kyu Daejeon-si KRAANM Kang; Shin GakAACI Daejeon-siAACO KRAAGP Kang; Shin Gak Daejeon-si KR - A method of providing timing information for synchronizing packet streams delivered from a first server and a second server, respectively, that are different from each other under hybrid delivery service environment is provided. The first server delivers a first media object and the second server delivers a second media object. The timing information for synchronizing a second packet including the second media object and a first packet including the first media object is generated in the second server. The timing information and the second packet including the second media object are provided from the second server to the client. | 01-17-2013 |
20130173826 | METHOD OF PROVIDING TIMING INFORMATION USING MMT SIGNALING LAYER SIGNALING FOR SYNCHRONIZING MMT PACKET STREAMS IN MMT HYBRID DELIVERY SERVICE AND METHOD OF SYNCHRONIZING MMT PACKET STREAMS IN MMT HYBRID DELIVERY SERVICE - A method for providing timing information for synchronizing between packet streams each transported from a first server and a second server under environment of a hybrid delivery service is provided. When the first server transports a first media entity and the second server transports a second media entity, timing information for synchronizing a second packet including a second media entity with a first packet including a first media entity in the second server is generated in response to a transport request for the second media entity from a client and the timing information and the second packet including the second media entity is provided to the client from the second server. | 07-04-2013 |
20140351874 | METHOD AND APPARATUS FOR TRANSMITTING MEDIA DATA FOR MMT SYSTEM, AND APPARATUS AND METHOD FOR RECEIVING MEDIA DATA - Provided are a method and apparatus for transmitting and receiving media data, which can provide D-layer timing information, which is transmitted from a media transmission service based on an MMT system and required for timely synchronization playout time of the media and media. The apparatus for transmitting the media data comprises a packetizer for generating a delivery layer packet (D-layer packet), which packetizes encapsulation layer data (E-layer data) to include timing information, wherein the timing information comprises sampling time information and transmission process delay information. | 11-27-2014 |

20130124699 | APPARATUS AND METHOD FOR TRANSCEIVING A STREAMING SERVICE - Provided is an apparatus and method for transmitting and receiving a streaming service. The apparatus and method for transmitting and receiving a streaming service may use a light multimedia file suitable for a Hypertext Transfer Protocol (HTTP) streaming service. Using an HTTP hint track, an International Organization for Standardization (ISO) file generated in a non-interleaved storing scheme that is unsuitable for an HTTP streaming service may be converted into an ISO file based on an interleaved storing scheme that is suitable for an HTTP streaming service. An ISO file may include multiple media tracks for supporting multiple bitrates and resolutions. Chunk data of media tracks that provide multiple multimedia qualities may be effectively acquired, and a light ISO file suitable for an HTTP streaming service may be generated by storing the acquired chunk data in an interleaved scheme. | 05-16-2013 |
20140369222 | METHOD FOR ESTIMATING NETWORK JITTER IN APPARATUS FOR TRANSMITTING CODED MEDIA DATA - The present invention relates to a method for estimating network jitter, which has the effect of more precisely estimating network jitter by using time information corresponding to a transmission time, which is transmitted from a transport layer in a transmitting end to a receiving end. | 12-18-2014 |

20130282871 | STREAMING SERVICE TRANSMITTING/RECEIVING DEVICE AND METHOD - Provided is an apparatus and method for transmitting and receiving a streaming service. An inter-arrival jitter may correspond to a delay variation in arrival time between TCP packets arriving at an apparatus for receiving the streaming service. The apparatus for receiving the streaming service may determine a de-jitter buffering time to absorb a network jitter before TS packets in a TCP packet is input to a T-STD buffer model. Based on the de-jitter buffering time, an initial playout delay lime at the apparatus for receiving the streaming service may be determined. | 10-24-2013 |
