专利汇可以提供Recording and reproducing device专利检索,专利查询,专利分析的服务。并且PURPOSE: To adopt the correspondence to an auxiliary part signal even for a simple type recording and reproducing device as a function by applying time division multiplex to a major part and an auxiliary part signal edited from narrow band video signals of plural divisions and plural time axis compression audio signals.
CONSTITUTION: The narrow band video signals divided into two by a video signal dividing circuit 40 and subjected to time base expansion are fed respectively to changeover switches 51, 52 and 53, 54. On the other hand, audio signals of channels 1, 2 and 3, 4 whose time base is compressed respectively via time base compression circuits 45, 46 and 47, 48 are edited respectively at mixing circuits 49, 50, become the major part and the auxiliary part audio signal and are fed respectively to the switches 51, 52 and 53, 54. Then the narrow band video signal and the major part audio signal are subjected to time division multiplex by the switches 51, 52 and recorded by magnetic heads 56, 57. On the other hand, the auxiliary part audio signal is subjected to time division multiplex and recorded by heads 57, 58. The reproduction is executed similarly, and the functioning correspondence of a simple type recording and reproducing device having no corresponding function to the auxiliary part signal is attained.
