摘要： Systems and method are provided for luma-chroma separation. A demodulator system demodulates a composite video signal to produce at least two baseband chroma signals. A given baseband chroma signal contains chroma information for one of a plurality of video frames comprising the composite signal. A three-dimensional (3-D) comb filter removes luma information from a given baseband chroma signal by combining sets of at least two baseband chroma signals to form a 3-D filtered baseband signal.

摘要： A video display system, such as useful in video surveillance applications, is disclosed. The system includes a video decoder (20) having a common output data port (27) at which it presents interleaved data streams (DSA, DSB). The interleaved data streams (DSA, DSB) may correspond to multiple scalings of a processed video input signal, for example as received from a surveillance camera (C1, C2, C3, C4). The video decoder (20) also outputs multiple clock signals (CLKA, CLKB), each of which are synchronous with a corresponding one of the interleaved data streams (DSA, DSB). This enables a common data port (27) to output multiple data streams (DSA, DSB), while individual destinations (30A, 30B) of the data streams (DSA, DSB) can continue to operate at legacy clock rates.
摘要翻译：公开了诸如在视频监控应用中有用的视频显示系统。该系统包括具有公共输出数据端口（27）的视频解码器（20），在该解码器（20）上呈现交织的数据流（DSA，DSB）。交织的数据流（DSA，DSB）可以对应于处理的视频输入信号的多个缩放，例如从监视摄像机（C 1，C 2，C 3，C 4）接收的。视频解码器（20）还输出多个时钟信号（CLKA，CLKB），每个时钟信号与交织的数据流（DSA，DSB）中的相应一个同步。这使得公共数据端口（27）能够输出多个数据流（DSA，DSB），而数据流（DSA，DSB）的各个目的地（30A，30B）可以继续以传统时钟速率运行。
