The present disclosure relates to an information processing device and method capable of suppressing an increase in load of processing of sensing data.

A bit depth of intermediate data generated from sensing data obtained in a sensor of an indirect time-of-flight (TOF) system is corrected, and the intermediate data with the bit depth corrected is encoded, and coded data is generated. For example, the bit depth of the intermediate data is corrected using a gamma curve that is a predetermined curve indicating input-output characteristics. The present disclosure can be applied to, for example, an image processing device, an image encoding device, an image decoding device, an imaging element, an imaging device, or the like.

A video packaging and origination service can include one or more encoder components that receive content for encoding and transmitting to requesting entities. During the operation of the encoder components, individual encoders receive input signals for encoding and determine quality metric information related to the generation of an encoded segment. The encoder components exchange quality metric information and an encoder component is selected to transmit an encoded segment. The selection of an individual encoder component per segment can continue throughout the streaming process.

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 data transmitting unit (30) sequentially transmits the 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. The encoding processing unit (28) encodes the given encoding unit by referring to the one or the plurality of referents, thereby generating the image data.

Identifying, by a sender and for each frame i of a plurality of frames of a video stream, a partition of a set of video data symbols D[i] into a first set of video data symbols U[i] and a second set of video data symbols V[i]. Generating, by the sender and for each frame i, a set of one or more streaming forward error correction (FEC) code parity symbols P.sub.x[i] based on the symbols: V[i−τ] through V[i−1], U[i−τ], and the symbols D[i], wherein τ is a function of a maximum tolerable latency of the video stream expressed as a whole number of frames. Encoding, by the sender and for each frame i, packets carrying the symbols D[i], and P[i]. Transmitting, by the sender, each frame i of encoded packets in frame order to one or more receivers.

Use of multiple sensors to determine whether motion of an object is occurring in an area is described. In one aspect, an infrared (IR) sensor can be supplemented with a radar sensor to determine whether the determined motion of an object is not a false positive.

A client device is configured to communicate with an access point over a wireless network, exchanging data with the access point over a selected communication channel. After the wireless connection to the access point has ended, the client device receives a probe from the access point over a low-level layer, such as a data link layer. In response to receiving the probe, the client device reconnects to the access point.

A signaling of at least one characteristic for layers of a multi-layered video signal such as, for example, for each layer the indication of dependent layers to which the respective layer directly relates via inter-layer prediction, or the signaling of the afore-mentioned second inter-dependency syntax structure, is described. A maximum syntax element is signaled within the multi-layered video signal to indicate a maximally used value of an extension layer-ID field of the packets of the multi-layered video signal, the scope of the maximum syntax element being, for example, a predetermined portion of the multi-layered video signal extending, for example, across several portions of the multi-layered video signal. Accordingly, it is feasible for devices such as decoders or network elements receiving the multi-layered video signal to gain, for a relatively large predetermined portion of the multi-layered video signal, knowledge about the actually consumed portion of the possible domain of possible values.
