Summary:To provide a digital broadcast receiving device that simplifies the transmission and reception of partial TLV streams.SOLUTION: A digital broadcast reception device based on an MMT/TLV system includes TLV stream extraction means, IP acquisition means, and PLT extraction means, and the TLV stream extraction means obtains a partial TLV stream, and the IP acquisition means extracts a TLV packet containing NTP data from the partial TLV stream and acquires an IP address from the UDP/IP packet included in the TLV packet, and the PLT extraction means identifies a PLT using the IP address.SELECTED DRAWING: Figure 10 【課題】パーシャルTLVストリームの送受信を簡易にするデジタル放送の受信装置を提供する。【解決手段】MMT/TLV方式に基づくデジタル放送の受信装置は、TLVストリーム抽出手段と、IP取得手段と、PLT抽出手段とを備え、TLVストリーム抽出手段は、パーシャルTLVストリームを得て、IP取得手段は、前記パーシャルTLVストリームからNTPデータが含まれるTLVパケットを抽出し、前記TLVパケットに含まれるUDP/IPパケットからIPアドレスを取得し、PLT抽出手段は、前記IPアドレスを用いてPLTを特定する。【選択図】図10
