    摘要： Embodiments of the present invention provide a video encoding system in which a video coding engine establishes coding quality metrics that govern its own operation as well as the operation of a camera and/or a pre-processor. An imaging system may include an image acquisition system, a pre-processor and a coding engine. The coding engine may output a quality indicator identifying, for each portion of a video sequence currently being coded, a relatively level of coding quality that is being achieved. The imaging system further may include an image acquisition controller and a pre-processor controller that impose respective operating parameters upon the image acquisition system and the pre-processor in response to these quality indicators. In this manner, overall performance of the imaging system may be improved.

    摘要： A video coding/decoding system builds implied reference frames from a plurality of reference frames developed during coding. Coded data of reference pictures are decoded and stored in a reference picture cache. An implied reference frame may be derived from a plurality of reference frames and may be stored in the reference picture cache. Thereafter, coding of new input data may proceed using the implied reference frame as a source of prediction. The method may be used to identify visual elements such as background elements that may persist in video over a longer period that can be captured by the system under conventional reference frames assembly and eviction. Implied reference frames may be built at both an encoder and a decoder to serve as sources of prediction.

    摘要翻译： 视频编码/解码系统从编码期间开发的多个参考帧构建隐含的参考帧。 参考图像的编码数据被解码并存储在参考图像缓存中。 可以从多个参考帧导出隐含的参考帧，并且可以将其存储在参考图像高速缓存中。 此后，可以使用隐含参考帧作为预测源来进行新输入数据的编码。 该方法可以用于识别视觉元素，例如可以在可在常规参考帧组装和驱逐下由系统捕获的较长时间段内持续存在视频的背景元素。 可以在编码器和解码器两者构建隐含的参考帧以用作预测的源。
