Abstract
A data transmitting apparatus which can reduce the load of the work of checking the AV data by the operator. AV data reproduced by a CM library (,) is recorded in a first cache (,) and second cache (,) via a distributor (,). At this time, the check sum regarding the AV data as the numerical value data is found in the calculating unit inside the CM library (,) and sent to a cache processing unit (,) via a library processing unit (,). The AV data recorded in said two caches are respectively subjected to test reproduction and the check sums are found by the calculating unit in each cache similar to the above. Where these check sums are all equal, it is decided that the transfer of the AV data was suitably carried out. Also, the AV data having a lower error rate between the AV data reproduced by the two caches is selected by the main switcher (,) and transmitted.
