Television signal converter for converting a high definition television signal into a television signal for display by a standard television receiver

摘要

According to the present invention, in a simple MUSE processing circuit, a high-definition television signal, which is band- compressed by an offset subsampling circulating in a field, is converted into a simple high Definition television signal, which is not a complete high Definition television signal, by superposing fields which are fewer than fields n. In a scanning line processing device, the simple high Definition television signal is converted into a first sequential scanning signal with at least the same number of scanning lines as the television signal in the present system. The first sequential scanning signal obtained by the scanning line processing device can be used as a Extended Definition television signal as it is. Also, in an interlaced converter, the first sequential scanning signal obtained by said scanning line processing device is converted into a first interlaced scanning signal which can be used in the television receiver in the present system.
