Abstract: For omnidirectional video such as 360-degree Virtual Reality (360VR) video, a video system that support independent decoding of different views of the omnidirectional video is provided. A decoder for such a system can extract a specified part of a bitstream to decode a desired perspective/face/view of an omnidirectional image without decoding the entire image while suffering minimal or no loss in coding efficiency.

Abstract: An audio synchronization method includes: receiving a first audio signal from a first recording device; receiving a second audio signal from a second recording device; performing a correlation operation upon the first audio signal and the second audio signal to align a first pattern of the first audio signal and the first pattern of the second audio signal; after the first patterns of the first audio signal and the second audio signal are aligned, calculating a difference between a second pattern of the first audio signal and the second pattern of the second audio signal; and obtaining a starting-time difference between the first audio signal and the second audio signal for audio synchronization according to the difference between the second pattern of the first audio signal and the second pattern of the second audio signal.

Abstract: A dynamic voltage and frequency scaling (DVFS) method includes obtaining at least one DVFS demand for DVFS of a processor system, and generating a control command of the DVFS of the processor system according to the at least one DVFS demand. The at least one DVFS demand includes a DVFS demand derived from an application demand, and the application demand is obtained from an application running on the processor system.

Abstract: A hybrid video decoding apparatus has a hardware entropy decoder and a storage device. The hardware entropy decoder performs hardware entropy decoding to generate an entropy decoding result of a picture. The storage device has a plurality of storage areas allocated to buffer a plurality of entropy-decoded partial data, respectively, and is further arranged to store position information indicative of storage positions of the entropy-decoded partial data in the storage device. The entropy-decoded partial data are derived from the entropy decoding result of the picture, and are associated with a plurality of portions of the picture, respectively.
