Abstract: Provided are a transmission apparatus, a transmission method, and a program that achieve transmission of image data having an appropriate referent with a small network load. An acquisition unit (26) sequentially acquires frame images drawn in a frame buffer. An encoding processing unit (28) sequentially encodes encoding units each corresponding to part or whole of one of the frame images and generates image data.

A transmission failure probability estimating unit (38) estimates, after the transmission of the image data, a transmission failure probability that is a probability of failure of the transmission of the image data. A referent determining unit (42) determines, in reference to the transmission failure probability of the image data, one or a plurality of referents that serve as a referent of a given encoding unit from the encoding units related to the image data transmitted.

Abstract: An acoustic-based Direction of Arrival (DoA) system uses acoustic information to determine the direction of incoming sound, such as a person talking. The direction of the sound is then used to focus a laser-based time of flight (ToF) system to narrow the area of laser illumination, improving the signal to noise ratio because laser illumination is focused on the direction of the sound. The DoA system also provides elevation information pertaining to the source of the sound, to further narrow the required field of view of the laser ToF system.

Abstract: Provided are an access control apparatus, an access control method, and a program that can reduce risks of tampering with a block while at the same time keeping ICV data size to a minimum. An individual key generation section (52) generates an individual key specific to an information processing apparatus (12). An ICV data generation section (56) generates, by using an individual key, ICV data that is based on verified digest value data, specific to the information processing apparatus (12), and smaller in data size than the digest value data. An ICV calculation section (64) calculates, by using the individual key, an ICV based on the block to which access is requested. A comparison section (66) compares the ICV indicated by a part of the ICV data corresponding to the block with the ICV calculated by the ICV calculation section (64). A writing section (68) writes the block to a memory in a case where the comparison succeeds.
