Abstract: The present disclosure relates to an information processing apparatus, an information processing method, a program, and a vehicle capable of predicting occurrence of a car traffic accident by detecting information regarding the other vehicle traveling around the vehicle and the other person who is a driver. An information processing apparatus according to a first aspect of the present disclosure includes a sensing unit that senses surrounding environment, a reception unit that receives information to prevent an accident regarding a predetermined area according to a current position, and a control unit that changes a parameter with which the sensing unit senses the surrounding environment on the basis of the information to prevent an accident received from the reception unit and a performance of the sensing unit. The present disclosure is capable of being applied to, for example, a car navigation system.

Abstract: [Object] To make it possible to transmit data more flexibly and with a lesser burden in an IDMA system. [Solution] There is provided an apparatus including: an acquisition unit configured to acquire an information block generated from transmission data for a user and subjected to error correction coding; and an interleaving unit configured to interleave a bit sequence of the information block using an interleaver unique to the user. The interleaving unit interleaves the bit sequence by interleaving each of two or more partial sequences obtained from the bit sequence.
