Video encoding and decoding method and apparatus using the same
The present invention is related to a method for moving the position of a base view from an arbitrary GOP (Group Of Pictures) start position to implement an efficient encoding structure in multi-view video encoding. The existing multi-view video encoding method exhibits low encoding efficiency when correlation between the base view and a dependent view is low, since the base view is assumed to be fixed.

Distributed control protocol for high availability in multi-node storage cluster
A distributed control protocol dynamically establishes high availability (HA) partner relationships for nodes in a cluster. A HA partner relationship may be established by copying (mirroring) information maintained in a non-volatile random access memory (NVRAM) of a node over a HA interconnect to the NVRAM of a partner node in the cluster. The distributed control protocol leverages a Cluster Liveliness and Availability Manager (CLAM) utility of a storage operating system executing on the nodes to rebalance NVRAM mirroring and alter HA partner relationships of the nodes in the cluster. The CLAM utility is configured to maintain various cluster related issues, such as CLAM quorum events, addition or subtraction of a node in the cluster and other changes in configuration of the cluster. Notably, the CLAM utility is an event based manager that implements the control protocol to keep the nodes informed of any cluster changes through event generation and propagation.

Accessing CP channels with LP terminals via wavefront multiplexing
Presented are methods that utilize wavefront multiplexing for enabling linearly-polarized terminals to access circularly-polarized satellite transponders. The methods disclosed herein feature (1) polarization formation capability that renders transmitted signal conditioned on circularly-polarized channels through multiple linearly-polarized feeds, and (2) polarization-conversion capability that compensate path differentials introduced by electromagnetic wave propagation channels. Data streams to be transmitted are pre-processed by a wavefront multiplexer into multiple wavefront components in linear polarization formats, where signals from respective data streams are replicated into linearly-polarized sub-channels. These replicated data streams are linked via a unique complex weighting vector (amplitude and phase or their equivalents), or “wavefront”, which are also linked by various spatially independent wavefronts. Additionally, a probing signal is sent on the transmitting side and linked via some of the independent wavefronts. Aggregated signals in linearly-polarized sub-channels are unique linear combinations of all input data streams. Aggregated signals in turn appear in circularly-polarized formats and propagate through circularly-polarized channels including circularly-polarized satellite transponders and a circularly-polarized teleport on the receiving side. Correlation between the circularly-polarized signal and the probing signal is sent back to the transmitting side that drives the polarization-conversion function toward the optimal state such that this correlation is lower than a pre-defined level. Accordingly, an optimally configured satellite communication system either (1) enables the linearly-polarized terminal on the transmitting side to access right-hand circularly-polarized satellite transponder without interfering the left-hand circularly-polarized satellite transponder, or (2) enables the linearly-polarized terminal on the transmitting side to access left-hand circularly-polarized satellite transponder without interfering the right-hand circularly-polarized satellite transponder.

Disclosed is an organic light emitting display device that comprises a first light emitting unit between a first electrode and a second electrode, the first light emitting unit including a first hole transporting layer and a first light emitting layer; and a second light emitting unit between the first light emitting unit and the second electrode, the second light emitting unit including a second hole transporting layer and a second light emitting layer that emits a light of the same color as a light emitted by the first light emitting layer. An increase in driving voltage caused by a shift of an emission zone in the first light emitting layer or the second light emitting layer by prolonged driving is minimized which solves a problem of increased power consumption and improves the lifetime of the organic light emitting display device.
The display device includes a first organic electroluminescence element which includes an anode and a cathode which form a pair, and a light emitting layer which is formed between the anode and the cathode on a substrate. The light emitting layer includes a plurality of sub-light emitting layers which perform light emitting of colors which are respectively different. Each of the plurality of sub-light emitting layers is doped with a quantum dot light emitting material corresponding to a color to be emitted. A current with current density corresponding to a position of a sub-light emitting layer of a desired color among the plurality of sub-light emitting layers is injected to the light emitting layer, and the sub-light emitting layer of the desired color performs light emitting.
