    • Method and apparatus for digital photograph presentation. A method for digital photograph presentation in accordance with one embodiment includes reading a still-picture file for a selected photograph from a DVD disk (402), transcoding (500) data from the still-picture file into a sequence of frames, and decoding and presenting the sequence. An apparatus for digital photograph presentation in accordance with one embodiment is a DVD player device (400 or 410) that includes a transcoder (404 or 412) for converting in real-time (see 500) still-picture files to sequences of frames, a navigator (406) for selecting the still-picture files and for controlling the transcoder (404 or 412) to direct presentation of the sequences. A method for digital photograph presentation in accordance with another embodiment includes encoding (300) onto a DVD disc (202) MPEG2 sequences that include the digital photographs as I-picture frames, inserting the DVD disc into a DVD player (200), and navigating amongst the MPEG2 sequences and displaying selected photographs using the DVD player (200). An apparatus for digital photograph presentation in accordance with another embodiment is a DVD player (400 or 410) that includes a navigator (204) for selecting the digital photographs encoded as MPEG2 sequences on a DVD disk (202), an MPEG2 decoder (104) for receiving and decoding the MPEG2 sequences, and a frame buffer (106) for buffering the decoded MPEG2 sequences to be output as at least one video signal from the DVD player.

    • When editing a digital image that has previously been saved in a lossy manner (whether such losses result from the editing operations and/or from inherently lossy image file formats such as JPEG), each additional editing session typically compounds the overall losses. As an alternative, we disclose creating and storing a proxy for an edited image, the proxy including a baseline image and a series of meta data representing editing operations performed on that image. During a subsequent editing session, the edited image can be partially or wholly reconstructed by applying the meta data to the baseline image, resulting in a comparatively lossless version thereof. The reconstructed image can be used as a starting point for additional edits, thereby minimizing the compound losses that would otherwise have resulted.
    • 当编辑先前以有损方式保存的数字图像(无论这种损失是由编辑操作导致的,还是由固有损耗的图像文件格式,如JPEG)时,每个附加的编辑会话通常会复杂整体损失。 作为替代,我们公开了为编辑的图像创建和存储代理,代理包括基线图像和表示在该图像上执行的编辑操作的一系列元数据。 在随后的编辑会话期间,可以通过将元数据应用于基线图像来部分地或全部地重构编辑的图像,导致其相对无损的版本。 重建图像可以用作额外编辑的起点,从而最小化否则会导致的复合损耗。

    • A method and system for reducing the resolution of media data. Input data at a first resolution are received from a source. The input data are compressed. The input data can be downsampled to generate compressed downsampled data at a reduced resolution. The compressed downsampled data can be used to generate a frame at the reduced resolution. When the frame is needed as a reference for another frame, the compressed downsampled data can be decoded to generate decompressed downsampled data at the reduced resolution. Motion compensation is performed on the decompressed downsampled data at the second resolution to generate motion compensated decompressed downsampled data used as a reference for a second frame. Thus, by performing motion compensation on downsampled data directly, data processing operations such as transcoding can be accomplished quickly and effectively while saving computing resources.
    • 一种降低媒体数据分辨率的方法和系统。 从源接收第一分辨率的输入数据。 输入数据被压缩。 可以对输入数据进行下采样,以降低分辨率产生压缩的采样数据。 压缩的下采样数据可以用于以降低的分辨率生成帧。 当需要帧作为另一帧的参考时,可以对压缩的下采样数据进行解码,以降低分辨率产生解压缩的下采样数据。 以第二分辨率对解压缩的下采样数据执行运动补偿,以产生用作第二帧的参考的运动补偿解压缩下采样数据。 因此,通过直接对下采样数据执行运动补偿,可以在节省计算资源的同时快速有效地实现诸如转码的数据处理操作。
