Title:
ブロードバンド信号で搬送されるトランスポートストリーム用の階層的モードを指示する方法、システムおよびネットワークエンティティ
Document Type and Number:
Japanese Patent JP4885456
Kind Code:
B2
Abstract:
A method for transmission, a method for reception, a system, a transmitter and a receiver for signalling a hierarchical priority mapping of a transport stream (TS) to a receiver is disclosed. A way to separate tuning information between different TSs with different priorities. In a wireless hierarchical broadband transmission, preferably based on DVB-T, one signal may carry two transport streams: low priority (LP) stream and high priority (HP) stream, and both should be identified with their own respective transport_stream_id. One bit flag is added into a certain descriptor of the broadband transmission to indicate the hierarchy of the transport stream on which said descriptor is providing information. By the appliance of this priority indication or priority flag, the receiver can obtain hierarchy mapping of each transport stream announced in the administrative information of the broadband transmission.
