Summary: | To provide a transmitter and a receiver that make it possible to suppress an increase in a jitter amount on the transmission side and prevent video destruction on the reception side, enabling content in IP packet form to be transmitted in bulk.SOLUTION: A transmitter 11 according to the present invention comprises: a content distribution unit 111 which, when transmitting content in IP packet form in bulk via a plurality of broadcast transmission channels, identifies and separates the multiple types of content data on the basis of each destination IP address; a TLV signal generation unit 112 that converts it into a TLV packet string for each type and constructs a TLV stream; a flag addition unit 113 that adds, to the packet type field of a prescribed TLV packet in the TLV stream, a flag that is identifiable on the reception side and that indicates switching of the transmission channels; and a divided frame generation unit 114 that controls transmission of the TLV stream in bulk, on the basis of a prescribed divided frame. A transmitter 17 according to the present invention detects the flag and reconstructs the TLV stream.SELECTED DRAWING: Figure 2
【課題】送信側のジッタ量の増大を抑制し受信側の映像破綻を防止してIPパケット形式のコンテンツをバルク伝送可能とする送信装置及び受信装置を提供する。【解決手段】本発明の送信装置11は、複数の放送伝送路を経てIPパケット形式のコンテンツをバルク伝送する際、その複数のコンテンツデータの種別について各宛先IPアドレスを基に判別し振り分けるコンテンツ分配部111、その種別毎にTLVパケット列に変換しTLVストリームを構成するTLV信号生成部112、当該TLVストリームにおける所定のTLVパケットのパケットタイプフィールドに、受信側で識別可能な伝送路切り替えを指定するフラグを付加するフラグ付加部113、及び所定の分割フレームを基準に当該TLVストリームをバルク伝送制御する分割フレーム生成部114を備える。本発明の送信装置17は、当該フラグを検出して当該TLVストリームを再構成する。【選択図】図2 |
