| 20090316891 | CONTENT REPRODUCTION APPARATUS, RECORDING APPARATUS, RECORDING AND REPRODUCTION APPARATUS, AND REPRODUCTION METHOD - In an apparatus of reproducing contents in which an encryption key is to be changed at predetermined intervals for copyright protection purpose, the contents can be reproduced or specially reproduced with no problem such as fast forward, and fast rewind. For special reproduction, data and key information needed therefor are made ready in advance, and using the data and the key information, the contents are specially reproduced. Alternatively, an encryption key generation rule is defined in advance for use in generation of an encryption key. By making any needed key information ready in advance from this rule, the contents can be reproduced and specially reproduced with no problem. | 12-24-2009 |

| 20100067527 | Packet Transfer Apparatus - A router stands by in a power saving state when there is no multicast joining message received. The router increases transfer performance with granularity such as the bandwidth of each multicast channel or the maximum bandwidth of each receiving line when a multicast joining message is received. On the other hand, the router decreases transfer performance with granularity such as the bandwidth of each multicast channel or the maximum bandwidth of each receiving line when a multicast disjoining message is received. The aforementioned processing permits achievement of power saving in the router connected to a multicast network. | 03-18-2010 |
