Title:
RECEPTION DEVICE, TRANSMISSION DEVICE, AND DATA PROCESSING METHOD
Document Type and Number:
WIPO Patent Application WO/2015/173986
Kind Code:
A1
Abstract:
This invention provides devices and a method for implementing robust display control for TTML subtitle data. A signaling message in the form of a TTML-subtitle-data-containing packet that contains TTML subtitle data as the payload of an MMT packet defined by the MMT format, and subtitle information corresponding to said TTML subtitle data, is transmitted from a transmission device to a reception device. Said signaling message defines, for example, a time mode (TMD), i.e. a mode for controlling subtitle display timing, or an operating mode (OPM) that selectively executes real-time subtitle display, display according to TTML markup, or the like. This allows the reception device to perform display control in accordance with the specified mode.
