    摘要: A signal processing apparatus capable of minimizing the required processing so that a data packet containing a described discontinuity information table can be inserted preferably in a transport stream (partial stream). In this apparatus, a stream layer model storage has a model of the table to be stored in a DIT (Discontinuity Information Table) packet indicating a discontinuity point of a stream layer. A DIT packet insertion controller refers to the information set in an insertion timing setting register and, upon arrival of the timing to insert the DIT packet, the information preset in a description contents setting register is inserted into the model to thereby generate the DIT packet, and then the generated packet is inserted at the discontinuity point of the transport stream (partial stream).

    摘要: A pointer measuring instrument capable of indicating “zero” on an indication panel by a pointer even if a play (backlash) is present in gears. The measuring instrument comprises a pointer reference position setting means (7a, 7b) for determining the reference position of the pointer (4). A control means (6) rotates the pointer (4) in the direction toward the reference position when a power supply to a stepping motor (2) is turned on, and performs a first drive for stopping the rotation of the pointer (4) when it receives a pointer reference position arrival signal from the pointer reference position setting means (7a). Then, the control means performs a second drive for moving the pointer (4) by a first angle from the reference position in the reverse direction away from the reference position, and performs a third drive for rotating the gear (3S) of a reduction mechanism (3) on the stepping motor (2) side by a second angle.
