用于确定胶片中的位置的设备及方法
摘要：
本发明描述了一种用于确定胶片(110)上的位置的设备，其中该设备包括：存储器(420)，用于按照时间顺序来存储施加于胶片(110)的胶片信息(112，114)，其中时标与所存储的胶片信息相关联；用于接收读取自胶片(110)的一部分的装置(440)；以及同步装置(460)，形成用于将基于第一采样率的读取部分的采样序列与所存储的胶片信息的第一搜索窗进行比较，以获得粗略结果，以及用于将基于第二采样率的读取部分的采样序列与所存储的胶片信息的第二搜索窗进行比较，以获得指示胶片(110)的位置的精细结果，其中所存储的胶片中的第二搜索窗的位置取决于粗略结果，其中第一搜索窗在时间上比第二搜索窗长，以及其中第一采样率低于第二采样率。
摘要（英）：

The invention relates to a device for determining a point in a film (110). The device has a memory (420) for storing film information (112, 114), which is applied on the film (110) in a temporal sequence. A time scale is assigned to the film information. A receiver (440) receives a part that is read by the film (110). A synchronizer (460) compares a first search window of the stored film information with a sequence of sample values of the read layer based on the read part of a first sample rate, in order to receive a rough result. The synchronizer compares a second search window of the storedfilm information with another sequence based on the read part of a second sample rate, in order to receive a fine result, which refers to the position of the film (110). wherein, the position of the second search window of the stored film information is determined by the rough result, the first search window is longer than the second search window in the time, and the first sample rate is lower than the second sample rate.
