Methods and apparatus for spatial error concealment. A method is provided for spatial error concealment. The method includes detecting a damaged macroblock, and obtaining coded macroblock parameters associated with one or more neighbor macroblocks. The method also includes generating concealment parameters based on the coded macroblock parameters, and inserting the concealment parameters into a video decoding system.

The invention is directed to a method and apparatus for providing temporal scaling frames for use in digital multimedia. The method involves using a removable unidirectional predicted temporal scaling frame communication along with intra-coded frames and/or inter-coded frames. The method involves the ability to selectively remove the temporal scaling frame(s) from being transmitted or decoded in order to satisfy, for example, power limits, data rate limits, computational limits or channel conditions. Examples presented include encoders, transcoders and decoders where the decision to drop the removable temporal scaling frames could be made.

A method sends a signal to render visual information on a display, and receives a user response to the rendered visual information. The user response includes a first delay. The method also queries an electronic system for data indicating a second delay. The second delay is a portion of the first delay and attributable to the electronic system. The method further using the data indicating the second delay to compensate for electronic system delay during interactions with a user.

This disclosure relates to techniques, devices, and systems for displaying sheet music on one or more electronic devices. One example method of displaying sheet music on an electronic device includes receiving a first electronic input that indicates timing information for a musical composition. The method also includes determining, by an electronic device, a timing parameter for the musical composition using the received first electronic input indicating the timing information, and displaying, on the electronic device, sheet music for a first portion of a plurality of portions of the musical composition. The method further includes determining a time duration associated with the first portion based on the timing parameter, and displaying, on the electronic device, sheet music for a second portion of the plurality of portions of the musical composition following an expiration of the time duration.

A method for creating an interpolated video frame using a current video frame, and a plurality of previous video frames is presented. The method includes creating a set of extrapolated motion vectors from at least one reference video frame in the plurality of previous video frames; performing an adaptive motion estimation using the extrapolated motion vectors and a class type of each extrapolated motion vector; deciding on a motion compensated interpolation mode; and, creating a set of motion compensated motion vectors based on the motion compensated interpolation mode decision. An apparatus for performing the method is also disclosed.

The invention comprises devices and methods for processing multimedia data to generate progressive frame data from interlaced frame data. In one aspect, a method of processing multimedia data includes generating spatio-temporal information for a selected frame of interlaced multimedia data, generating motion information for the selected frame, and deinterlacing fields of the selected frame based on the spatio-temporal information and the motion information to form a progressive frame associated with the selected frame. In another aspect an apparatus for processing multimedia data can include a spatial filter module configured to generate spatio-temporal information of a selected frame of interlaced multimedia data, a motion estimator configured to generate motion information for the selected frame, and a deinterlacer configured to deinterlace fields of the selected frame and form a progressive frame corresponding to the selected frame based on the spatio-temporal information and the motion information.

A technique for processing video to determine which segments of video originate in a telecine and which conform to the NTSC standard is described herein. The current pull-down phase of the 3:2 pull-down (see below) in a telecine generated video segment is estimated and used to invert the telecine process.

In general, this disclosure describes encoding and decoding techniques that facilitate more accurate interpolation of skipped video frames. In particular, techniques are described for obtaining motion information that indicates motion for skipped video frames based on translational motion and at least one other motion parameter and applying the motion information to interpolate the skipped video frames. The motion information may, for example, indicate motion based on a motion model that models three or more motion parameters as opposed to conventional two parameter translational motion vectors. The more accurate motion information may either be generated within the decoder performing the interpolation or be transmitted by an encoder in one or more frames. Either way, the techniques reduce the amount of visual artifacts in the interpolated frame.
摘要:
A method and apparatus to process erroneous bi-directionally predicted multimedia data is described. The method includes determining temporal prediction data for the erroneous multimedia data, and estimating the erroneous multimedia data based on the determined temporal prediction data. The temporal prediction data includes data that was used to predict a forward reference section and/or a backward reference section. In some aspects, the temporal prediction data comprises motion vector data of the reference frames which is scaled to correspond to a frame containing the erroneous data.
