Abstract: Provided is a communication method of a coordinator in a wireless networks system that uses a reservation-based media access control (MAC). The communication method includes receiving, from a source device, a frame that requests a reservation resource for a relay device, to enable a frame that the source device transmits to a destination device to be relayed via the relay device, and allocating the reservation resource for the relay device, in response to the request.

Abstract: Disclosed are an apparatus and a method for transmitting a broadcasting service capable of signaling non-real-time 3D broadcasting content. An apparatus for transmitting a broadcasting service includes: a non-real-time (NRT) content encoder encoding stereoscopic image content including a reference image and an additional image to generate an NRT stream; an NRT signaling information encoder generating NRT signaling information including at least one of a service map table (SMT) and a non-real-time-information table (NRT-IT) that correspond to the content; and a multiplexer multiplexing the NRT stream and the NRT signaling information and transmitting the multiplexed NRT stream and NRT signaling information to a receiving apparatus. Therefore, content can be provided even when the reference image and the additional image are encoded into the single file format in the dual stream type.

Abstract: Disclosed herein are a transmission apparatus and method and a reception apparatus and method for a program associated stereoscopic broadcasting service. The transmission apparatus includes: a real time stream encoder generating a real time stream by encoding a reference image; a non-real time (NRT) stream encoder generating an NRT stream based on an additional image; an image synchronization information generator generating a service signaling and image synchronization information (including an event information table (EIT) and a program map table (PMT)) stream for synchronizing the reference image and the additional image with each other based on 3D content synchronization information; and a re-multiplexer generating a program associated stereoscopic broadcasting stream by multiplexing the real time stream, the non-real time stream, and the service signaling and image synchronizing information stream.
