摘要： Image data is processed to produce an output using a frame insertion approach. According to an example embodiment, frames are generated for video data, based upon the video data and the presence (or absence) of artifacts in the video data. In one application, a dynamic frame insertion approach is used to selectively generate peaked and blurred video frames in a manner that mitigates undesirable display and/or enhancement of artifacts by tuning down or turning off the generation and/or insertion of video frames.

摘要： Principles, apparatuses, systems, circuits, methods, and computer program products for performing a software upgrade in a MoCA network includes receiving an image of a software upgrade at a server and sending the image in the MoCA network using an L2ME message channel to a client that is enabled to receive the image and store the image in a client memory. The image may be broken up into packets, and a sequence number may be assigned to each packet to assist the client in assembling them. CRC information may also be appended to the packets to enable the client to verify their contents.

摘要： Low complexity method directly decode low-resolution frames from compressed high-resolution videos that were encoded using predictive coding techniques like the H.264 video coding standard. The smaller the decoding resolution, the higher will be the computation and power savings of using the method. Low-frequency coefficients of 2D transformed predictions are added to the low-frequency coefficients of the transformed residual error. Low-frequency coefficients of the reconstructed data are then inverse transformed taking a smaller size transform. Further savings are obtained by reconstructing only those reference pixels that will be needed for accurate decoding of further Intra blocks.

摘要： The invention relates to a method for obtaining transformation parameters. A camera motion can be modeled by providing a vector field of motion vectors describing estimated motion vectors, projecting the vector field on at least one axis, and deriving the transformation vector parameters from the projection of the vector fields. As the camera motion can be modeled by way of translation, scale and rotation, the projections of the vector field on the axis can be used.

摘要： According to some embodiments of the disclosed method and apparatus, systems and methods are provided that utilize extra payload capacity present in a symbol pad of a PHY payload to decrease the coding rate of an FEC coding scheme without increasing the symbol rate or decreasing the PHY rate of a corresponding data transmission. If a symbol pad length that would result from encoding a MAC frame using a default coding scheme would be at least as great as a parity length of the default coding scheme, and a new coding scheme maintaining the same parity length but having a reduced information bit length may be determined and used to encode the MAC frame. Owing the reduced information bit length, the new coding scheme has a reduced coding rate, but maintains the same number of OFDM symbols as the default coding scheme.
