  • Publication number: 20240048784
    Abstract: There is provided a signal input unit to prevent or reduce an increase in memory hardware on a transmitter or a receiver of a serial digital signal, and to decrease the load on a CPU. The signal input unit receives as an input a video signal and a digital signal for transmission, the digital signal for transmission including a data packet with metadata associated with the video signal. The data writing unit extracts predetermined metadata from the digital signal for transmission on the basis of metadata-specifying information and writes the extracted metadata in an accumulating register. For example, the metadata-specifying information includes header information of the data packet with the predetermined metadata. For example, the header information includes classification information indicating a classification for the predetermined metadata and auxiliary information of the predetermined meta-information.
