Abstract:
A method of receiving a broadcast signal including a Non-Real-Time (NRT) service and a broadcast receiver are disclosed herein. A method of receiving a broadcast signal including a Non-Real-Time (NRT) service, the method comprises receiving a broadcast signal including an NRT content and NRT service guide information, the NRT service guide information including a content fragment, identifying a File Delivery over Unidirectional Transport (FLUTE) session delivering the NRT content from the broadcast signal, detecting a first content identification information from a File Description Table (FDT) of the FLUTE session, and detecting a second content identification information of the content fragment matched with the first content identification information.
Abstract:
A broadcast receiver receives a packetized stream. The broadcast receiver extracts display time information from the header of the received packetized stream, and extracts preparation trigger information including a target service identifier from the payload of the received packetized stream. If a current time is a preparation time designated by the extracted display time information, the broadcast receiver starts to prepare an object corresponding to the target service identifier for activation at a later time.
Abstract:
A method for receiving a 3D image broadcast signal for processing edge violation in a multi-view 3D image comprises the steps of: receiving a broadcast signal for broadcasting the multi-view 3D image; decoding from the received broadcast signal first left image data and first right image data which is included in a 3D image of a first view; parsing from the received broadcast signal 3D image processing information; generating second left image data and/or second right image data which is included in a 3D image of a second view, by using the first left image data, the first right image data, and the 3D image processing information; parsing 3D edge violation area detection function information included in the 3D image processing data; and handling edge violation of the area by using the 3D edge violation area detection function information.
Abstract:
The method for transmitting an image component for a 3D image according to one embodiment of the present invention comprises: a step of generating one or more texture image components and one or more depth map image components; a step of generating an SEI (supplemental enhancement information) message including a 3D layer information element for signaling layer information relating to coding between said one or more texture image components and one or more depth map image components; a step of generating an NAL unit including the SEI message including said 3D layer information element; and a step of generating a broadcast signal including said one or more texture image components, said one or more depth map image components and the NAL unit.
Abstract:
According to the invention, a broadcast receiver receives a packetized stream. The broadcast receiver extracts display time information from a header of the packetized stream, and extracts trigger information including a target object identifier from a payload of the packetized stream. The broadcast receiver recognizes the type of the trigger information. If the trigger information is of the preparation trigger type, the broadcast receiver acquires information on the location of the file which belongs to the target object identifier. The broadcast receiver downloads the file which belongs to the target object identifier from the time corresponding to the extracted display time information via said acquired information on the location of the
