Reception manner of teletext data

机译:图文电视数据的接收方式

摘要

(57) Abstract The case of reception of the teletext page in order decoding certainty of knowledge, it is high relatively vis-a-vis the address frame of one page which possesses the supplement data for relatively high level especially vis-a-vis the address frame of the teletext page, without addition error prevention means to achieve decoding of the teletext page of one it was done, and, with when error the address frame for the teletext string which follows from the address frame amendment is forecast (prediction). As for the address frame which is forecast (prediction) the actual address frame in the teletext string which follows is received it is compared. The case of particular comparison and the case of decoding of the address frame which is received by when two of the bytes of one or at many information units than that deflection is detected, the address frame which is forecast (prediction) is used because of addressing of the data current for the particular teletext string in place of the address frame which is received.
