| 20090067360 | METHOD AND APPARATUS FOR ALLOCATING MULTICAST CONNECTION IDENTIFIER USED FOR IP MULTICAST PACKET TRANSMISSION OVER PORTABLE INTERNET NETWORK AND TRANSMITTING PACKET USING THE MULTICAST CONNECTION IDENTIFIER - Provided is a method and apparatus for allocating a multicast connection identifier (MCID) for Internet protocol (IP) packet transmission over a portable Internet network and transmitting packets using the MCID. More specifically, there is provided a method of defining and allocating an MCID for transmitting an IP version 6 (IPv6) multicast packet over an IEEE 802.16/Wireless Broadband (WiBro) network and a process for transmitting an IP multicast packet of a base station (BS) using the MCID. The method of allocating is related to a method of automatically generating a connection identifier (CID) having 16 bits for packet transmission over the IEEE 802.16/WiBro network in order to transmit the IPv6 multicast packet. In this method, a scope value of the IPv6 multicast packet is added to the MCID. Therefore, multicast packets having an effective IPv6 scope such as a multicast packet in a link-local category, a multicast packet in a site-local category, and a multicast packet in a global category can be transmitted over the IEEE 802.16/WiBro network according to the scope of the multicast packet. Accordingly, when a new IPv6 scope is defined, the method can be naturally applied. | 03-12-2009 |
| 20090290564 | APPARATUS FOR AND METHOD OF SUPPORTING NETWORK-BASED MOBILITY FOR DUAL STACK NODES - An apparatus for and method of supporting network-based mobility for a dual stack terminal are provided. More particularly, a mobile anchor point (MAP) apparatus for binding and data transmission of a dual stack terminal which has moved from a dual network to an Internet Protocol version 4 (IPv4) network or an Internet Protocol version 6 (IPv6) network, and a method of implementing the MAP apparatus are provided. If the IPv6, which is a next-generation Internet protocol, begins to be applied to networks, a dual stack terminal supporting both the IPv4 and IPv6 will also be introduced. In an environment in which this dual stack terminal moves, movement of the dual stack terminal to an IPv4-only network or an IPv6-only network as well as movement between IPv4/IPv6 dual networks will be considered. According to the apparatus and method, a MAP used in a conventional network-based mobility supporting method is extended. Accordingly, when a dual stack terminal moves between different network-based localized mobility management domains, such as an IPv4-only network or an IPv6-only network, a binding management message is made to be exchanged between two MAPs of the networks, thereby establishing an IPv6-in-IPv4 tunnel or an IPv4-in-IPv6 tunnel between the two MAPs. In this way, even when the dual stack terminal moves to an IPv4-only network or an IPv6-only network, communication with an external terminal is enabled. | 11-26-2009 |

| 20100232334 | BASE STATION AND METHOD OF AVOIDING FLOOD OF JOIN MESSAGES FOR IP MULTICAST GROUP IN PORTABLE INTERNET NETWORK - Provided is a base station (BS) and method of avoiding a flood of join messages for an Internet protocol (IP) multicast group in a portable Internet network, and more particularly, to a BS and method of transmitting join messages for an Internet IP multicast group to an access router or other BSs with a predetermined delay time in an IP multicast (IP version 4 (IPv4) or IP version 6 (IPv6)) service in an IEEE 802.16/Wireless Broadband (WiBro) network. In addition, the BS immediately transmits the join message for the group to other user terminals which belong to the BS. Accordingly, a problem whereby a method of avoiding a flood of multicast group join messages cannot be applied due to point-to-multipoint characteristics of the portable Internet network such as the IEEE 802.16/WiBro network is solved. In addition, the method of avoiding a flood of join messages can be applied using both IPv4 multicast and IPv6 multicast services. | 09-16-2010 |

| 20080232470 | Method of Scalable Video Coding and the Codec Using the Same - Since joint scalable video coding (JSVC) adopts a scheme in which numbers are assigned to all of the pictures according to the order in which the pictures are displayed, it is difficult to detect a drop (or loss) of a key picture and thus it is difficult to effectively take action against an error caused by the loss of the key picture. The present invention provides a coding method of detecting a loss of a key picture by numbering key pictures in JSVC in which predictive (P) pictures have a closed-loop structure and of effectively taking action against an error in the case of a loss of a key picture, and a codec using the coding method. The SVC method includes performing encoding while assigning a number to a key picture of an upper layer and performing decoding with respect to the number-encoded current key picture of the upper layer using data of a decoded image of a picture of a lower layer that is temporally matched with the current key picture of the upper layer when a loss of a key picture between the number-encoded current key picture of the upper layer and a previous key picture that is number-encoded prior to the current key picture is detected. Therefore, it is possible to effectively take action against to an error caused by a loss of a key picture by detecting the loss of a key picture during decoding by encoding using numbering of key pictures in JSVC in which closed-loop coding is performed by consecutively predicting key pictures. Moreover, it is possible to minimize degradation in image quality by concealing an error caused by an incorrect reference by using data of a decoded image of a corresponding picture of a lower base layer when a key picture of an upper layer is lost in an environment where transmission of the lower base layer is guaranteed with a video stream having a multi-layered structure. | 09-25-2008 |

The pixel prediction unit determines whether to apply differential pulse coded modulation (DPCM) to each of pixels of the residual image block based on a rate distortion optimization (RDO) value calculated for the case where DPCM is applied to each of the pixels of the residual image block and a RDO value calculated for the case where DPCM is not applied to each of the pixels of the residual image block. The entropy-coding unit performs entropy-coding on the residual image block. | 06-25-2009 |
