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. Moreover, in case the view in a live broadcasting program desired by a producer changes from the base view to another, the user has to consume more bit streams and decoder complexity than those consumed when decoding is performed with respect to the base view. Therefore, to alleviate the drawbacks of the existing multi-view video encoding method, the present invention provides a method for designing syntax elements by which the base view can be moved, thereby supporting an efficient encoding structure. |

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. |
