Abstract: Techniques pertaining to scalable video codec are disclosed. According to one aspect of the present invention, a video image is analyzed and a region of interest (ROI) and a region of non-interest (non-ROI) are identified. By comparing the non-ROI image with that of a previous image, a background ignored identifier is created indicating whether the non-ROI can be ignored during encoding and decoding processes. Based on the status of the background ignored identifier, the encoder encodes the images into a basic layer (BL) and an enhanced layer (EL), and transmits the coded bit streams along with the identifier to a decoder. The decoder reconstructs the image based on the identifier and the BL and the EL bit streams.

Abstract: Techniques for determining positions of pilot sub-carries in a received OFDM symbol are described. Components of pilot sub-carries from a theoretical OFDM symbol are extracted to form M theoretical pilot sequences according to M possible distributions in frequency domain of the pilot sub-carries in the theoretical OFDM symbol. Components of pilot sub-carries from the received OFDM symbol are also extracted to form K hypothetical pilot sequences according to K possible distributions in frequency domain of pilot sub-carries in the received OFDM symbol. The correlations of every two adjacent elements of the theoretical pilot sequences are calculated to get M corresponding theoretical correlation sequences, and the correlations of every two adjacent elements of the hypothetical pilot sequence are also calculated to get K corresponding hypothetical correlation sequences. Sequence correlations between the hypothetical correlation sequences and the theoretical correlation sequences are then calculated. The positions of pilot sub-carriers in the received OFDM symbol can be determined from the one that has the maximum modulus value.

Abstract: Systems and processes for mobile device management (MDM) implement scoped MDM policies. A mobile device has containers to isolate data and processes on the mobile device from the others of the containers. The scoped MDM policies involve container level commands and device level commands. The mobile device has a first agent residing in a first container and a controller residing within a second container. The controller executes a first device level command to control access to the resources of the mobile device for all containers. The first agent or the controller executes a first container level command to control access to the resources of the mobile device by only the first container.
