前記受信手段により受信されたＱＡＭ方式の信号を復調する復調手段と、
前記複数トランスポートストリームに含まれて前記単一トランスポートストリームに含まれないフレームヘッダパケットを用いて前記複数トランスポートストリーム伝送方式と前記単一トランスポートストリーム伝送方式とを判別し、単一トランスポートストリームの場合はそのまま出力し、複数トランスポートストリームの場合は指定された一つのトランスポートストリーム形式のデジタルデータを分離してそのトランスポートストリームを出力する分離手段とを備えたことを特徴とする受信装置。 A plurality of transport streams in which a plurality of transport stream format digital data is multiplexed and a single transport stream in which transport stream format digital data is multiplexed and transmitted in one transport stream are mixed. Receiving means for receiving a signal transmitted by the QAM system;
Demodulation means for demodulating a QAM signal received by the receiving means;
A plurality of transport stream transmission methods and a single transport stream transmission method are discriminated using a frame header packet included in the plurality of transport streams and not included in the single transport stream, and a single transport A receiving unit comprising: a separating unit that outputs a stream in the case of a stream, and in the case of a plurality of transport streams, separates digital data in one designated transport stream format and outputs the transport stream. apparatus.
前記分離手段で分離されたトランスポートストリーム形式のデジタルデータに基づく映像を表示する表示手段とを備えたことを特徴とする受信装置 The receiving device according to claim 1,
And a display unit for displaying video based on the digital data in the transport stream format separated by the separation unit.
前記フレームヘッダパケットの有無を検出する場合に、取得したトランスポートストリームのPIDが複数トランスポートストリームのフレームヘッダパケットPIDと一致するかどうかの判定を少なくとも２回行うことを特徴とする受信装置。 The receiving device according to claim 1,
A receiving apparatus, wherein when detecting the presence or absence of the frame header packet, it is determined at least twice whether or not the acquired PID of the transport stream matches the frame header packet PID of the plurality of transport streams.
