Electronic apparatus and communication control method

A communication control method comprising:

• decoding a control stream in encoded content data, the encoded content data comprising an audio/video stream and the control stream for controlling the audio/video stream;
• transmitting the audio/video stream and the control stream to an external electronic apparatus, wherein first time information is added to the audio/video stream and second time information is added to the control stream;
• and
• executing, in response to a user operation in the external electronic apparatus, a process corresponding to the user operation by using the decoded control stream while video using the audio/video stream and the control stream is being displayed on a screen of the external electronic apparatus.

A computer-readable, non-transitory storage medium having stored thereon a program which is executable by a computer, the program controlling the computer to execute functions of:

• decoding a control stream in encoded content data, the encoded content data being content data comprising an audio/video stream and the control stream for controlling the audio/video stream;
• transmitting the audio/video stream and the control stream to an external electronic apparatus, wherein first time information is added to the audio/video stream and second time information is added to the control stream;
• and
• executing, in response to a user operation in the external electronic apparatus, a process corresponding to the user operation by using the decoded control stream while video using the audio/video stream and the control stream is being displayed on a screen of the external electronic apparatus.
