Abstract
When a frame information (F1)C2 defining the frame type in a transmission protocol format is received in a pager, data of a following interleaving portion is received. A receiving buffer circuit converts the received data from serial data into parallel data in accordance with the frame type, and a deinterleaving circuit reproduces (deinterleaves) the converted parallel data.
Claims20
A data receiving apparatus comprising:
- a receiver configured to receive information data in which data frames have been interleaved according to a plurality of interleave types;
- an interleave type detector configured to detect an interleave type of the received information data;
- a data buffer circuit configured to change an arrangement of the data frames on the information data received by said receiver;
- a de-interleave circuit configured to change an arrangement of the data frames output from said data buffer circuit;
- and
- a controller configured to selectively operate both of said and de-interleave circuit or only said data buffer circuit based on the interleave type detected by said interleave type detector,
- wherein the data frames included in the received information data are reproduced as one of an output of the data buffer circuit and an output of the deinterleave circuit in accordance with the interleave type detected by said interleave type detector.

A data receiving method comprising the steps of:
- receiving information data in which data frames have been interleaved according to one of a plurality of interleave types;
- detecting an interleave type of the received information data;
- first, changing an arrangement of the received data frames;
- and
- second, changing the arrangement-changed receive data if the detected interleave type is a predetermined type, whereby data frames included in the received information data is reproduced as one of a result of the first changing and a result of the second changing according to the detected interleave type.
