Abstract: A decoding apparatus is provided for decoding transport streams in which compressed video and audio data, a program association table (PAT), and program map tables (PMTs) are multiplexed. The apparatus comprises a specification unit, a search unit, and decoding circuits. The specification unit allows a user to specify a service ID and program IDs corresponding to user's desired video and audio data. The search unit searches service IDs described on the PAT and program IDs on the PMT for the service ID and the program IDs specified through the specification unit. Determinations for consistency are made between the service ID described on the PAT and the user's desired service ID and between the program IDs on the PMT and the user's desired program IDs. The decoding circuits decode compressed video and audio data corresponding to the service ID and the program IDs searched by the search unit.

Abstract: In a brushless motor, the number of coreless armature coils is set to 3n when the number of magnetic poles of a magnet for a magnetic field is set to 2n where n is a positive integer. An opening angle of each of the armature coils is set to 360/3n degrees. A notch portion is formed in an outer circumferential portion of the magnet for a magnetic field. A recessed portion is formed by this notch portion and an inner circumferential portion of a yoke. The recessed portion constitutes a groove for correcting a balance of each of the magnet for a magnetic field and a rotating body when this magnet and the rotating body are rotated. A motor housing and a harness are electrically connected to a printed board. The housing is connected to the ground through this harness and a harness for power. In this brushless motor, a magnetizing frequency is reduced and driving efficiency of a control circuit can improved when the brushless motor is rotated at a high speed.
