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
