1. A content receiving apparatus comprising:
a first content receiver configured to receive contents and control information regarding content protection for the contents received by the first content receiver, which are transmitted in a first transmission method;
a second content receiver configured to receive contents and control information regarding content protection for the contents received by the second content receiver, which are transmitted in a second transmission method, the second transmission method being different from the first transmission method;
a storage configured to store the contents received by the first content receiver or the second content receiver;
a first video output interface configured to output, to first external equipment, video of the contents received by the first content receiver or the second content receiver, or video of the contents stored by the storage;
a second video output interface configured to output, to second external equipment, video of the contents received by the first content receiver or the second content receiver, or video of the contents stored by the storage, the second video output interface being a different type of interface from the first video output interface;
an infrared communication interface; and
a controller configured to control content protecting processes for the storage, the first video output interface, or the second video output interface,
wherein a first type of content protection is applicable for the first video output interface,
wherein at least two levels of content protection in the first type of content protection are applicable for the first video output interface,
wherein a second type of content protection is applicable for the second video output interface, the second type of content protection being different from the first type of content protection,
wherein at least two levels of content protection in the second type of content protection are applicable for the second video output interface,
wherein control states of the storage, the first video output interface, and the second video output interface controlled by the controller include:
a first video outputting process state in which the storage does not store the contents and the contents are outputted from the first video output interface to the first external equipment;
a storing process state in which the storage stores the contents; and
a second video outputting process state in which the contents are outputted from the first video output interface to the first external equipment, or from the second video output interface to the second external equipment, after a storing process for the contents by the storage,
wherein the controller is configured to execute switching of the levels of the content protecting processes for the first video output interface in accordance with a number of pixels of the video of the contents received by the first content receiver in the first video outputting process state,
wherein the controller is configured to execute switching of the levels of the content protecting processes for both the first video output interface and the second video output interface in accordance with the number of pixels of the video of the contents in the second video outputting process state,
wherein the number of pixels of a threshold value to execute the switching of the levels of the content protecting processes is equal between the first video outputting process state and the second video outputting process state,
wherein the content protecting processes in the first video outputting process state and the second video outputting process state for the contents with a number of pixels that is equal to or less than the number of pixels of the threshold value in the contents received by the first content receiver is common to the content protecting processes in the first video outputting process state and the second video outputting process state for the contents received by the second content receiver, for each of the first video output interface and the second video output interface, and
wherein the second video output interface is a LAN interface.
