摘要： The present technology relates to a data processing device and a data processing method which can ensure high communication quality in data transmission using LDPC codes.
In group-wise interleaving, an LDPC code having a code length N of 64800 bits and a coding rate r of 11/15 is interleaved in a unit of a bit group of 360 bits. In group-wise deinterleaving, a sequence of bit groups of the LDPC code which has been subjected to the group-wise interleaving is returned to an original sequence. The present technology can be applied to, for example, a case in which data transmission is performed using LDPC codes.-

摘要： The present technique relates to a data processing apparatus and a data processing method each of which enables a burden imposed on processing on a reception side to be reduced.
A data processing apparatus produces signaling containing a Null cell number exhibiting the number of Null cells of cells of a sub-frame included in a physical layer frame, and processes the signaling so as for the signaling to be contained in a preamble of the physical layer frame, thereby enabling a burden imposed on processing on a reception side to be reduced. The present technique, for example, can be applied to data transmission complying with the broadcasting standards such as ATSC3.0.-

摘要： The present technology relates to a reception apparatus, a reception method, a transmission apparatus, and a transmission method, by which channel selection information can be acquired more efficiently. Provided is a reception apparatus, including: a reception unit that receives a broadcast wave of digital broadcasting using an IP (Internet Protocol) transmission system; a communication unit that receives first signaling information for acquiring broadcast content transmitted by the broadcast wave through communication with a server via a network; an acquisition unit that acquires, on the basis of the first signaling information, a physical parameter used in a physical layer in a hierarchy of a protocol of the IP transmission system; and a control unit that controls, on the basis of the physical parameter, operations of respective units that perform channel selection processing.

摘要： Display with an appropriate luminance dynamic range is realizable on a receiving side. A gamma curve is applied to input video data having a level range from 0% to 100%*N (N: a number larger than 1) to obtain transmission video data. This transmission video data is transmitted together with auxiliary information used for converting a high-luminance level on the receiving side. A high-level side level range of the transmission video data is converted on the receiving side such that a maximum level becomes a predetermined level based on the auxiliary information received together with the transmission video data.

摘要： A receiving device including a receiver and circuitry is provided. The receiver is configured to receive a digital broadcast signal transmitted using an Internet Protocol (IP) transmission method. The digital broadcast signal includes Layered Coding Transport (LCT) packets. The circuitry is configured to extract one of the LCT packets based on filtering information arranged in a header of the one of the LCT packets transmitted in a first layer that is higher than an IP layer of a protocol of the IP transmission method in the digital broadcast signal, and process first signaling data contained in the one of the LCT packets. The LCT packets are transmitted using a session of the first layer. The filtering information includes compression information indicating compression/no-compression of the first signaling data, and type information indicating a type of the first signaling data.

摘要： Identification of services that carry the same or equivalent content. A reception apparatus includes circuitry configured receive first service information for a first service included in a first broadcast stream, and receive second service information for a second service included in a second broadcast stream. The first service is associated with a first virtual channel number and the second service is associated with a second virtual channel number. The circuitry is configured to determine whether the first service included in the first broadcast stream contains the same programming content as a service included in another broadcast stream based on the first service information. The first service information includes an identifier included in the second service information when the first service included in the first broadcast stream contains the same programming content as the second service included in the second broadcast stream.

摘要： There is provided a transmission apparatus including: a processing unit that performs processing of mixing, at a mixing rate independent for each frame, image data in peripheral frames with image data in each frame of first moving image data at a first frame rate and obtains second moving image data at the first frame rate. At least image data in a frame corresponding to a second frame rate that is lower than the first frame rate in the image data in each frame that forms the second moving image data is brought into a state in which the image data is mixed with the image data in the peripheral frames.

摘要： A transmission apparatus configured to mix, at a mixing rate, pixels of first video data with pixels of peripheral frames of the first video data and obtain second video data at a first frame rate. The mixing rate for each pixel of a frame of the first video data is based on a luminance value of the pixel. The second video data includes frames having a second frame rate lower than the first frame rate. The apparatus encodes the frames having the second frame rate to obtain a basic stream and encodes remaining frames of the second video data to obtain an extended stream, inserts information about the mixing rate into the basic stream and the extended stream in association with each frame, and transmits the basic stream and the extended stream into which the information about the mixing rate has been inserted.
