    • An adaptive stream player that has control over whether a retrieved stream is cached in a local stream cache. For at least some of the stream portions requested by the player, before going out over the network, a cache control component first determines whether or not an acceptable version of the stream portion is present in a stream cache. If there is an acceptable version in the stream cache, that version is provided rather than having to request the stream portion of the network. For stream portions received over the network, the cache control component decides whether or not to cache that stream portion. Thus, the cache control component allows the adaptive stream player to work in offline scenarios and also allows the adaptive stream player to have rewind, pause, and other controls that use cached content.
    • 控制是否将检索到的流缓存在本地流缓存中的自适应流播放器。 对于播放器请求的至少一些流部分,在通过网络出去之前,高速缓存控制组件首先确定流高速缓存中是否存在流部分的可接受版本。 如果流缓存中有可接受的版本,则提供该版本,而不必要求网络的流部分。 对于通过网络接收的流部分,高速缓存控制组件决定是否高速缓存该流部分。 因此,高速缓存控制组件允许自适应流播放器在脱机情况下工作,并且还允许自适应流播放器具有使用缓存内容的倒带,暂停和其他控制。

    • A method of color image compression processing provides compensation for lossy luminance compression (30) by adjusting (34) the red and blue color components using a lossy luminance compression factor equal to the difference between compressed and decompressed luminance. The compensated color components are then used to compute (42) chrominance color differences. Chrominance is range compressed (44) by bit-reduction using a non-linear range compression function that minimizes compression for small chrominance magnitudes, where the eye is more sensitive to a loss of color fidelity, while maximizing compression in the color saturation regions where the eye is less sensitive. After luminance and chrominance decompression (60) and reconversion to the RBG color components (70), compensation for red and blue color shift (such as due to round-off errors) is accomplished by multiplying (80) the green component (which is calculated from the color-shifted red and blue components) by a color shift compensation factor that shifts green in the opposite direction from the shift in the red and blue components.
    • 彩色图像压缩处理的方法通过使用等于压缩和解压缩亮度之间的差的有损亮度压缩因子来调节(34)红色和蓝色分量来提供对有损亮度压缩的补偿(30)。 然后使用补偿的颜色分量来计算(42)色度色差。 色度通过使用非线性范围压缩函数的比特缩减进行压缩(44),其使针对小色度幅度的压缩最小化,其中眼睛对色彩保真度的损失更敏感,同时最大化色饱和度区域中的压缩 眼睛敏感度较低。 在亮度和色度解压缩(60)并重新转换为RBG颜色分量(70)之后,通过将(80)绿色分量(其被计算的)乘以来实现红色和蓝色偏移的补偿(例如由于舍入误差) 来自颜色偏移的红色和蓝色分量)的色移补偿因子,其在与红色和蓝色分量的偏移相反的方向上移动绿色。
