20120320990 | METHOD AND APPARATUS FOR ENCODING VIDEO, AND METHOD AND APPARATUS FOR DECODING VIDEO - Disclosed is a method of encoding a video, the method including: splitting a current picture into at least one maximum coding unit; determining a coded depth to output a final encoding result according to at least one split region obtained by splitting a region of the maximum coding unit according to depths, by encoding the at least one split region, based on a depth that deepens in proportion to the number of times the region of the maximum coding unit is split; and outputting image data constituting the final encoding result according to the at least one split region, and encoding information about the coded depth and a prediction mode, according to the at least one maximum coding unit. | 2012-12-20 |
20120320991 | ERROR RECOVERY USING ALTERNATE REFERENCE FRAME - A system, apparatus, and method for decoding a video signal having a plurality of frames including a current frame. Decoding the video signal includes generating an alternate reference frame, detecting an error in the current frame and reporting the detected error, receiving a recovery frame in response to reporting the detected error, wherein the recovery frame is encoded using the alternate reference frame; and decoding the recovery frame using the alternate reference frame. The alternate reference frame occurs prior to the current frame in the video signal and is other than a frame immediately prior to the current frame. | 2012-12-20 |
20120320992 | ENHANCING COMPRESSION QUALITY USING ALTERNATE REFERENCE FRAME - A system, apparatus, and method for decoding a video signal having a plurality of frames including a current frame. Decoding the video signal can include generating an alternate reference frame having a first quality level, determining a boost value indicative of a second quality level higher than the first quality level, determining whether to apply the boost value to the alternative reference frame, and selectively applying the boost value to the alternative reference frame if it is determined to apply the boost value to the alternative reference frame. The alternate reference frame can occur prior to the current frame in the video signal and other than a frame immediately prior to the current frame. | 2012-12-20 |
20120320993 | APPARATUS AND METHOD FOR MITIGATING THE EFFECTS OF PACKET LOSS ON DIGITAL VIDEO STREAMS - Apparatuses, systems, and methods for mitigating the effects of patent loss on a video stream are disclosed. The method can include encoding and transmitting a video stream by separating the video stream into a plurality of component video streams, such that each component video stream includes pixel color values associated with a color component of the color space, encoding at least a portion of the component video streams into component bitstreams, packetizing at least a portion of the component bitstreams into a plurality of packets such that no one packet of the plurality of packets includes color values corresponding to each of the plurality of color components for any frame of the plurality of frames, using a processor, and transmitting the plurality of packets. | 2012-12-20 |
