    • A channel estimation treatment method and device for obtaining binary data conveyed in a signal. The method includes: obtaining a current vector of channel estimates, each element of the current vector corresponding to an estimate of a subchannel; detecting, inside the current vector, at least one pilot symbol; splitting the current vector in at least two subvectors, at least one first subvector including channel estimates related to data symbols and/or pilots symbols and at least one second subvector including channel estimates related to null symbols; decoding the at least one first subvector, delivering at least one first treated subvector; modifying the at least one second subvector by assuming presence of pilot symbols in the at least one second subvector, delivering at least one second treated subvector; and calculating a new vector of channel estimates with the at least one first treated subvector and the at least one second treated subvector.

    • A two-dimensional filter operates in accordance with a three-dimensional television signal having a basic layer, a reference processing unit layer and an enhancement layer. The two-dimensional filter generates a processed base layer reference picture from a base layer reference picture via a one-dimensional horizontal filter that horizontally filters the base layer reference picture to generate a first filtered base layer reference picture and a one-dimensional vertical filter, coupled to, but separable from, the one-dimensional horizontal filter, that vertically filters the first filtered base layer reference picture to generate a pre-processed base layer reference picture.
    • 二维滤波器根据具有基本层,参考处理单元层和增强层的三维电视信号进行操作。 二维滤波器通过水平滤波基本参考图像以生成第一滤波的基本参考图像和一维垂直滤波器的一维水平滤波器从基本层参考图片生成经处理的基本层参考图像, 耦合到一维水平滤波器但是可以与一维水平滤波器分离,其垂直地滤波第一滤波的基本参考图像以产生预处理的基本层参考图像。
