Abstract:
1. A communication apparatus comprising: a reading unit that reads video data from a storage medium; a transmitting unit that transmits video data, read from the storage medium by the reading unit, to a receiving apparatus via a predetermined line; a first detecting unit that detects a level of a signal transmitted from the receiving apparatus to the communication apparatus; a second detecting unit that detects a level of a termination voltage relating to the predetermined line; an obtaining unit that obtains first information relating to the receiving apparatus from the receiving apparatus; and a control unit that (a) executes a determination process for determining whether the communication apparatus and the receiving apparatus are connected if the communication apparatus is in a first mode, (b) stores second information indicating whether the communication apparatus and the receiving apparatus are connected after the determination process is performed, and (c) controls, based on the second information, a execution of the determination process after an instruction for changing the communication apparatus from the first mode to a second mode is inputted to the communication apparatus, wherein the determination process includes a process for determining, based on at least one of a detected result of the first detecting unit and a detected result of the second detecting unit, whether the communication apparatus and the receiving apparatus are connected, wherein the first mode is used for transmitting video data, read from the storage medium by the reading unit, to the receiving apparatus.
