Abstract: An image processing apparatus for processing first image data into second image data having a higher quality includes the following elements. A determination unit determines whether broadcast image data is up-converted image data generated by up-converting different image data by increasing the number of pixels forming the different image data. A down-converter down-converts the broadcast image data into down-converted image data by decreasing the number of pixels forming the broadcast image data. A first image converter converts, if the broadcast image data is not the up-converted image data, the first image data into the second image data by using the down-converted image data and the broadcast image data as the first image data. A second image converter converts, if the broadcast image data is the up-converted image data, the first image data into the second image data by using the down-converted image data as the first image data.

Abstract: Embodiments of the present invention comprise systems and methods for image noise characterization, parameterization, removal, reconstruction and/or re-combination with a denoised image.

Abstract: An apparatus and method for storing digital broadcast data in a digital broadcast receiving terminal. If the digital broadcast receiving terminal enters a weak electric field strength region during reception of digital broadcast data, digital broadcast receiving terminal stops the process of receiving the digital broadcast data so as to check whether digital broadcast receiving terminal re-enters again into the strong electric field strength region. Then, if the digital broadcast receiving terminal re-enters the strong electric field region, the terminal shifts a TS value of a received digital broadcast data frame to the value obtained by adding a frame interval of the digital broadcast data frames to the TS value of the previous data frame that had been completely stored just before the digital broadcast receiving terminal entered the weak electric field strength region.

Abstract: A recording apparatus capable of multiplexing video data and audio data and recording the video data and audio data in multiple record units as one file on a recording medium includes a data receiving unit, a recording instruction receiving unit, a packet generating unit, a recording unit, and a control unit. The control unit controls the packet generating unit and the recording unit so as to record data embedded with padding data in a section from the trailing end of valid data to the trailing end of the block including the trailing end of the valid data at stop of the recording and to record data embedded with the padding data in a section from the trailing end of the block to the trailing end of the packet including the trailing end of the block at restart of the recording after the recording is stopped.

Abstract: The present invention comprises a system and method for controlling the rate a data encoder generates compressed data. The system and method are preferably implemented as program code stored and executed by a processor or computer that is interfaced to standard variable or constant bit rate encoders known in the art. The system preferably encodes and compresses video signals received from a camera, and controls the rate at which the compressed data is generated by the encoder so that storage capacity reserved for the compressed data will not be exceeded. The device preferably takes advantage of periods when the data generation rate is low to increase the quality of video data generated during periods of high activity.

The content reception/recording device comprises: a receiving unit; an accumulation medium; a storage unit storing therein free time slot information that indicates a free time slot in which a predetermined operation specified by a user is not performed; an obtaining unit operable to obtain transmission timing information that indicates timings at which contents are transmitted respectively; a determining unit operable to, when a plurality of accumulation target contents are transmitted in the free time slot, determine priorities of the contents for being accumulated in the free time slot, in accordance with the transmission timing information obtained by the obtaining unit; and a control unit operable to control the receiving unit to receive the accumulation target contents in accordance with the determined priorities and to accumulate the received contents in the accumulation medium.

Abstract: An information processing method includes the steps of analyzing moving-image content including image data and audio data, extracting scene metadata characterizing each scene for each scene constituting the moving-image content, deciding a reproduction mode of the moving-image content according to at least one of a reproduction environment of the moving-image content and setting information set by a user, generating loss recovery information for recovering loss information lost by changing the reproduction mode of the moving-image content using the scene metadata according to the decided reproduction mode, and outputting the generated loss recovery information in accordance with the moving-image content to be reproduced in the decided reproduction mode.

Abstract: If a movie reproducing apparatus detects an error during reproduction of encoded movie data, based on management information that includes a recording position of an intra-picture coded picture included in the encoded movie data, the movie reproducing apparatus determines a position used when the error is recovered by searching for an intra-picture coded picture subsequent to a frame including data with the error as well as updates elapsed time information to be displayed based on a frame number of the searched intra-picture coded picture at the time the error is recovered.

Abstract: A media archive comprising a plurality of media resources associated with events that occurred during a time interval are processed to synchronize the media resources. Sequences of patterns are identified in each media resource of the media archive. Elements of the sequences associated with different media resources are correlated such that a set of correlated elements is associated with the same event that occurred in the given time interval. The synchronization information of the processed media resources is represented in a flexible and extensible data format. The synchronization information is used for correction of errors occurring in the media resources of a media archive, for enhanced synchronous playback of the archive resources, and for unified access to, and modification of, the archive resources.

Abstract: An audio-video processing method is adapted to an audio-video device and a storage device for processing an index-based audio-video file. The method for processing audio-video data includes a write procedure, a play procedure, and/or a repair procedure. In the write procedure, audio-video data is captured by the audio-video device first, and the audio-video data includes a plurality of continuous samples; a header is written according to the audio-video data; a predetermined number of samples are captured as a data chunk; a prefix index corresponding to the data chunk and the data chunk are written in sequence repeatedly according to the audio-video data; and a file index is written finally. In the play procedure, after the header is read, corresponding prefix index and data chunk are repeatedly read and played. Moreover, in the repair procedure, incompletely written file index and data chunk are repaired through all the prefix indexes.

Abstract: A method and system for encoding and recording data in a multi-stream format when the data is initially captured. The multiple streams of data can be combined to provide a high quality, or high resolution, representation, while a reduced subset of the streams can provide a lower quality, or lower resolution, representation. Data storage requirements can be reduced, by deleting one or more of the streams, when there is no longer a need for retention of the data at the higher quality.
