Video information playback method, video information playback device, recording medium and video content

A video information playback device comprising a playback means for playing back a virtual-machine-using content from a recording medium, the recording medium having thereon:

• a virtual machine;
• one or more virtual-machine-using contents whose video playback can be controlled by a program running in the virtual machine;
• and
• a program for determining whether each of the one or more virtual-machine-using contents is a first type content capable of being played back either when the program running in the virtual machine is activated or deactivated, or a second type content capable of being played back only when the program running in the virtual machine is activated;
• the video information playback device comprising:
• a means for determining by the program whether the virtual-machine-using content is the first type content or the second type content when a playback stop instruction to stop playback of a virtual-machine-using content currently being played back is given from a user, and recording information of the determining in a memory of the video information playback device;
• a means for reading the information of the determining regarding the virtual-machine-using content to be playback-resumed when a playback resume instruction is inputted to the video information playback device, and determining whether the virtual-machine-using content to be playback-resumed is the first type content or the second type content;
• and
• a playback control means for resuming playback from a playback stop position without activating the program running in the virtual machine if the virtual-machine-using content to be playback-resumed is determined to be the first type content, and resuming playback after activating the program running in the virtual machine if the virtual-machine-using content to be playback-resumed is determined to be the second type content.

A recording medium, on which information for playing back video content by the video information playback device is recorded,

• the information including:
• a virtual machine;
• one or more virtual-machine-using contents whose video playback can be controlled by a program running in a virtual machine;
• and
• a program running in the virtual machine for determining whether each of the one or more virtual-machine-using contents is a first type content capable of being played back either when the program running in the virtual machine is activated or deactivated, or a second type content capable of being played back only when the program running in the virtual machine is activated.

A video content to be played back by a video information playback device, the video content including:

• a virtual machine;
• one or more virtual-machine-using contents whose video playback can be controlled by a program running in the virtual machine;
• and
• a program running in the virtual machine for determining whether each of the virtual-machine-using contents is a first type content capable of being played back either when the program running in the virtual machine is activated or deactivated, or a second type content capable of being played back only when the program running in the virtual machine is activated.

A video information playback method of playing back a virtual-machine-using content from a recording medium by a video information playback device, the recording medium having thereon:

• a virtual machine;
• one or more virtual-machine-using contents whose video playback can be controlled by a program running in the virtual machine;
• and
• information of determining indicating whether each of the one or more virtual-machine-using contents is a first type content capable of being played back either when the program running in the virtual machine is activated or deactivated, or a second type content capable of being played back only when the program running in the virtual machine is activated;
• the method comprising the steps of:
• reading the information of the determining regarding the virtual-machine-using content to be playback-resumed, when a playback resume instruction is inputted to the video information playback device after playback of a virtual-machine-using content currently being played back is stopped, and determining whether the virtual-machine-using content to be playback-resumed is the first type content or the second type content;
• and
• resuming playback from a playback stop position without activating the program miming in the virtual machine if the virtual-machine-using content to be playback-resumed is determined to be the first type content, and resuming playback after activating the program running in the virtual machine if the virtual-machine-using content to be playback-resumed is determined to be the second type content.

A video information playback device comprising a playback means for playing back a virtual-machine-using content from a recording medium, the recording medium having thereon:

• a virtual machine;
• one or more virtual-machine-using contents whose video playback can be controlled by a program running in the virtual machine;
• and
• information of determining indicating whether each of the one or more virtual-machine-using contents is a first type content capable of being played back either when the program running in the virtual machine is activated or deactivated, or a second type content capable of being played back only when the program running in the virtual machine is activated;
• the video information playback device comprising:
• a determination means for reading the information of the determining regarding the virtual-machine-using content to be playback-resumed when a playback resume instruction is inputted to the video information playback device after playback of the virtual-machine-using content currently being played back is stopped, and determining whether the virtual-machine-using content to be playback-resumed is the first type content or the second type content;
• and
• a playback control means for causing the playback means to resume playback from a playback stop position without activating the program running in the virtual machine if the virtual-machine-using content to be playback-resumed is determined to be the first type content, and causing the playback means to resume playback after activating the program running in the virtual machine if the virtual-machine-using content to be playback-resumed is determined to be the second type content.

A recording medium on which information for playing back video content by a video information playback device is recorded;

• the information including:
• a virtual machine;
• one or more virtual-machine-using contents whose video playback can be controlled by a program running in the virtual machine;
• and
• information of determining indicating whether each of the one or more virtual-machine-using contents is a first type content capable of being played back either when the program running in the virtual machine is activated or deactivated, or a second type content capable of being played back only when the program running in the virtual machine is activated.

A video content being played back by a video information playback device;

• the video content including:
• a virtual machine;
• one or more virtual-machine-using contents whose video playback can be controlled by a program running in the virtual machine;
• and
• information of determining indicating whether each of the one or more virtual-machine-using contents is a first type content capable of being played back either when the program running in the virtual machine is activated or deactivated, or a second type content capable of being played back only when the program running in the virtual machine is activated.
