Abstract: A method of processing additional information related to an announced service or content in a Non-Real Time (NRT) service and the broadcast receiver are disclosed herein. A method of providing a Non-Real Time (NRT) service in a broadcasting receiver includes receiving a service map table (SMT) and a first descriptor through a service signaling channel, identifying an image identifier and an image type of an image for an NRT service based upon the first descriptor, receiving the image via a flute session and displaying the image when corresponding service is played, wherein the image is logo or icon data for the NRT service. The method may further include connecting a service signaling channel, parsing the received SMT and the first descriptor, determining whether a service is the NRT service based upon the parsed SMT and storing the received image.

Abstract translation: 本文公开了处理与非实时（NRT）服务中的所宣布的服务或内容有关的附加信息的方法。 在广播接收机中提供非实时（NRT）服务的方法包括通过业务信令信道接收服务映射表（SMT）和第一描述符，识别图像标识符和用于NRT的图像的图像类型 基于第一描述符的服务，经由长笛会话接收图像并在播放相应的服务时显示图像，其中图像是用于NRT服务的徽标或图标数据。 该方法还可以包括连接服务信令信道，解析所接收的SMT和第一描述符，基于所解析的SMT确定服务是否为NRT服务并存储所接收的图像。

Abstract: The invention relates to a transmitting system, comprising an SNS client that receives SNS messages from at least one SNS server, and a transmitter which transmits a broadcast signal, including the SNS messages and mobile service data, for a mobile broadcast. The transmitter includes: an RS frame encoder, which performs RS encoding and CRC encoding on the mobile service data for the mobile broadcast so as to build RS frames, and divides each RS frame into a plurality of portions; a group-forming unit, which forms data groups that contain each of the plurality of portions, and which adds known data sequences and signaling data to each data group; an inter-leaver for interleaving data of the data groups; and a trellis encoding unit for trellis-encoding the interleaved data.
