专利汇可以提供Onal replenishment video encoder with predictive updating19730313专利检索,专利查询,专利分析的服务。并且Each new sample from a video signal is compared with a sample derived from a frame memory having the same spatial point location in the video frame. If a significant difference exists, the new sample replaces the old sample in the frame memory and is stored in a buffer memory. The frame memory is composed of three delay lines connected in tandem having delay values such that the samples preceding and following the center delay line correspond to spatial points above and below the sample being compared. If a significant difference exists and if the buffer memory is filled to a predetermined level, the samples preceding and following the center delay line are also predictively updated with values derived from the value of the new sample. Different functions are used to predictively update during the even and odd fields and greater differences are required to exist before they are deemed to be significant during the even fields in order to avoid the creation of an unstable condition.,下面是Onal replenishment video encoder with predictive updating19730313专利的具体信息内容。
