Abstract: PURPOSE:To shorten the access time by providing a plurarity of track line velocity and controlling motor rotation so that the difference of both track rotation numbers become minimum when shifting from the 1st to the 2nd track. CONSTITUTION:Plural kinds of linear velocity of the track where a pickup 5 is located are provided. The pickup 5 is shifted from a given 1st track to a given 2nd track of a recording disk 1. In this case, the pickup 5 controls the rotation of a spindle motor 3 so that the absolute value of each difference between the number of disk rotations when the pickup 5 is located at the 1st track and the number of rotations of the recording disk 1 in some linear velocity is made minimum. In this case, a linear velocity switching control signal is outputted from a CPU9 to a servo circuit 4. As a result, the access time can be made shorter than usual.

Abstract: PROBLEM TO BE SOLVED: To freely change a device for performing radio communication and to prevent a cryptographic from being known to a user. SOLUTION: When the user operates a switch 94, a CPU 41 sets an operation mode in a transmission mode for transmitting a WEP (Wired Equivalent Privacy) key. In the transmission mode, a radio transmitting/receiving module 92 transmits key information about the WEP key to a receiving part 31. Also, when the user operates a switch 104, the switch 104 sets an operation mode in a transmission mode. In the transmission mode, a radio transmitting/receiving module 101 receives the key information transmitted from the radio transmitting/receiving module 92. This invention is applicable, for example, to a wireless television. COPYRIGHT: (C)2005,JPO&NCIPI

Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of such inconvenience that video and sound offered to a user side are broken by transmitting prescribed data a plurality of times (making prescribed data redundant and transmitting data). SOLUTION: A TS packet string 111 with an RTP (real time protocol) header 112 attached includes audio data. A TS packet string composed only of the audio data is a TS packet string 121. An RTP header of the packet string 121 composed only of the audio data is the RTP header 112. Namely, in this case, an RTP packet having a number called the same "1235h" as a "sequence number" is continuously transmitted two times. If a receiving side can receive even one between the RTP packets transmitted twice, it is possible to prevent such inconvenience that sound to be offered to the user is broken because there is no omission about audio data. This invention is applicable to a transmitter and a receiver for exchanging data. COPYRIGHT: (C)2005,JPO&NCIPI
