    • Embodiments herein provide for a pre-processing stage or mechanism for enhancing data compression of an image by splitting or separating the color channels for pixels into planar data sources. Typically, image data is displayed as an interleaved set of channel types for a color space such that each pixel within an image (such as a bitmap) has one component for each color channel. By separating the interleaved bitmap into a planar representation, each plane can be compressed independently and often times achieve higher compression ratios. This is especially true for channels that are expected to stay fairly constant throughout the bitmap most of the time. The utilization of the above embodiment can be further enhanced through manipulation of channel data or through converting the color space from one form to another.
    • 这里的实施例提供了用于通过将像素的颜色通道分割或分离为平面数据源来增强图像的数据压缩的预处理阶段或机制。 通常,图像数据被显示为用于颜色空间的交织的通道类型集合,使得图像(例如位图)内的每个像素具有每个颜色通道的一个分量。 通过将交错位图分离为平面表示,可以独立地压缩每个平面,并经常实现更高的压缩比。 对于大多数时间内预期在整个位图中保持相当稳定的通道,这一点尤其如此。 通过操纵频道数据或通过将颜色空间从一种形式转换到另一种形式,可以进一步增强上述实施例的利用。

    • The present invention provides for transferring slideshow presentation information from a host computing device to an electronic device that typically has limited resources. A request to display a slideshow presentation on an electronic device is received, the slideshow presentation including image data corresponding to one or more bitmaps. In response to the request, a session of an application is open on the host computer that provides the slideshow presentation data. A video codec is utilized for dynamically converting the slideshow presentation data into a video data stream that represents the slideshow presentation. The video data stream is then transmitted to the electronic device for rendering the slideshow presentation on a display of the electronic device.
    • 本发明提供将幻灯片演示信息从主机计算设备传送到通常具有有限资源的电子设备。 接收在电子设备上显示幻灯片演示的请求,该幻灯片演示包括对应于一个或多个位图的图像数据。 响应于该请求,在提供幻灯片呈现数据的主计算机上打开应用程序的会话。 视频编解码器用于将幻灯片演示数据动态地转换成表示幻灯片呈现的视频数据流。 然后将视频数据流发送到电子设备,以便在电子设备的显示器上呈现幻灯片演示。
