    Abstract: An image-based motion sensor has a camera system and a processing system. The camera system generates an image output including a plurality of captured images. The processing system obtains a motion sensor output by processing the image output, and identifies a user input as one of a plurality of pre-defined user actions according to the motion sensor output. Different functions of at least one application performed by one electronic device are controlled by the pre-defined user actions. The motion sensor output includes information indicative of at least one of a motion status and an orientation status of the image-based motion sensor. Each of the captured images has more than one color component, and only values of one single color component are involved in obtaining the motion sensor output.

    Abstract: A transmitter device includes a processing unit and a compression unit. The processing unit obtains a branch of data and partitions the branch of data into a plurality of snippets. Each snippet includes a group of data. The compression unit compresses each snippet into a plurality of packets according to value of each datum included in the corresponding snippet. The compression unit compares the value of each datum with a first threshold value to generate a first packet. The first packet includes first information indicating which data included in the corresponding snippet has the corresponding value not equal to the first threshold value. The compression unit further generates the remaining packets according to the first information.

    Abstract: An exemplary decoding method of an input video bitstream including a first bitstream and a second bitstream includes: decoding a first picture in the first bitstream; after a required decoded data derived from decoding the first picture is ready for a first decoding operation of a second picture in the first bitstream, performing the first decoding operation; and after a required decoded data derived from decoding the first picture is ready for a second decoding operation of a picture in the second bitstream, performing the second decoding operation, wherein a time period of decoding the second picture in the first bitstream and a time period of decoding the picture in the second bitstream are overlapped in time.
