LDPC coding is executed using a check matrix of an LDPC code whose code length is 736 bits and whose code rate is 1/4, and modulation is executed using a repetition unit that has an LDPC code obtained by the LDPC coding, repeatedly arranged therein. The LDPC code includes information bits and parity bits, the check matrix includes an information matrix portion corresponding to the information bits and a parity matrix portion corresponding to the parity bits, the parity matrix portion has a stepwise structure, the information matrix portion is indicated by a check matrix initial value table, and the check matrix initial value table is a predetermined table indicating positions of elements of '1' of the information matrix portion for each eight columns. This technique is applicable to, for example, information transmission using the LDPC code.

Transmitting apparatus and transmission method, receiving apparatus and reception method, and program

An electronic device that transmits, via a first communication interface to another electronic device, an IP (Internet Protocol) address; and communicates with the another electronic device via a second communication interface in accordance with the IP address.

Wireless communication device and wireless communication method

[Object] To perform appropriate transmission band control. [Solving Means] An information processing apparatus includes an acquisition section and a controller. Here, the acquisition section acquires user information generated by a user operation when information based on a stream communicated between another information processing apparatus via wireless communication is output from an output section. The controller performs band control of the stream communicated between another information processing apparatus via wireless communication based on the user information acquired by the acquisition section.

Information processing for band control of a communication stream

A first device for processing data, the first device including at least one control circuit configured to adjust at least one parameter related to a delay time based on a measured value of the delay time. The measured value of the delay time is a difference between a first time associated with when the first device processes the data and a second time associated with when a second device processes the data.

Device, method and computer readable medium

The present disclosure relates to a terminal device, a communication method, a program, and a communication system, which can enable one-on-many wireless communication among terminal devices with less trouble for the user. A communication system according to the present disclosure is a communication system in which one parent device and a plurality of child devices perform one-on-many wireless communication. The parent device includes a management unit which manages group information representing a group made up of two or more child devices to which a child device belongs, and a child device connecting unit which establishes wireless connection with the child device which performs notification of the group information that matches the managed group information, and consecutively establishes wireless connections with a plurality of child devices. On the other hand, the child device includes a notifying unit which notifies the parent device of group information representing a group made up of two or more child devices, to which it itself belongs, and a parent device connecting unit which establishes wireless connection with the parent device in response to a predetermined trigger. The present disclosure can be applied to a system which distributes data by one-on-many wireless communication.
