Abstract
A digital video apparatus connectable to Universal Serial Bus (USB) receives, from a control apparatus, a first request for requesting to change a status of the digital video apparatus to a predetermined status and transmits, to the control apparatus, notification information before a lapse of a predetermined time, the notification information notifying the control apparatus that the status of the digital video apparatus is changed. The digital video apparatus receives, from the control apparatus, a second request for requesting information representative of the status of the digital video apparatus if the notification information cannot be transmitted before the lapse of the predetermined time and transmits, to the control apparatus, information representative of the status of the digital video apparatus in response to the second request.
