Digital broadcasting receiver, digital signal processor, and control method for digital broadcasting receiver

摘要

An apparatus and a control method for an apparatus includes: a tuner for transmitting a demodulation signal which is a signal generated by demodulating a receiving signal of a digital broadcast; a digital signal processor for decoding the demodulation signal and transmitting a first video signal to an external device; a general-purpose processor for generating a second video signal to be synthesized with the first video signal; a video signal synthesizing circuit for synthesizing the second video signal with the first video signal; and a user interface for accepting from the external device an input of a starting signal which is a signal instructing a start of video signal output. The digital signal processor and the general-purpose processor start respective boot sequences in response to the acceptance of input of the starting signal by the user interface, and the digital signal processor starts the decoding of the demodulation signal before the boot sequence of the general-purpose processor is completed.
