Abstract

The purpose of the invention is to transfer HDR image data between devices in a good way. A sending device (source device) sends HDR image data to a receiving device (sink device) via a channel. In this process, the transmitting device transmits transmission format information and / or gamma correction information of the HDR image data to the receiving device via the channel. The receiving device performs processing (decoding processing, gamma correction processing, etc.) on the received HDR image data based on the received transmission format information and / or gamma correction information. For example, the sending device receives from the receiving device the information of the transmission format and / or the gamma correction format compatible with the receiving device, and selects the format compatible with the receiving device for use.

Description

technical field [0001] The present invention relates to a transmitting device, a method of transmitting image data of a high dynamic range, a receiving device, a method of receiving image data of a high dynamic range, and a program, and more particularly relates to a high Dynamic range image data transmission device, etc. Background technique [0002] In recent years, for example, a high-definition multimedia interface (HDMI) has been popularized as a communication interface through which digital picture signals (that is, uncompressed (baseband) picture signals (image data) and Digital voice signals (voice data)) are sent at high speed from a digital versatile disk (DVD) recorder, set-top box, or other audio-visual (AV) source to a television receiver, projector, or other display. For example, the HDMI specification is described in detail in NPL 1. [0003] For example, consider an AV system or the like in which a disk player as a source device and a television receiver as...
