According to one embodiment, an electronic apparatus includes a decoder, a transmitter and an operation processor. The decoder decodes a control stream in encoded content data including an AV stream and the control stream for controlling the AV stream. The transmitter transmits the AV stream and the control stream to an external apparatus, wherein first time information is added to the AV stream and second time information is added the control stream. The operation processor executes, in response to a user operation in the external apparatus, a process corresponding to the operation by using the decoded control stream while video is being displayed on a screen of the external apparatus.
