Description
本発明の実施形態は、放送信号送受信装置に関する。 Embodiments of the present invention relates to a broadcast signal receiving equipment.
実施形態によれば、
ＭＭＴ−ＴＬＶ方式で多重されている信号を送受信する放送信号送受信装置において、
送信側は、
前記信号を放送信号として送信する送信部と、
前記信号に含まれる制御信号の情報を設定する設定部と、
を有し、
前記設定部は、前記制御信号のうち、前記信号がＩＰ再放送される場合に、前記信号から分離したＭＨ−ＣＤＴ（MH-Common Data Table）を集約して前記信号とは別にＩＰマルチキャストの伝送路に送出する際に前記信号に含まれて放送信号として送信されたことを識別させるために、前記ＭＨ−ＣＤＴ（MH-Common Data Table）のtlv_stream_idを、前記tlv_stream_idと同じビット長であって前記信号を識別する第２のtlv_stream_idに置き換えて設定し、
受信側は、
ＩＰ再放送された、前記信号から前記第１の制御情報を除いたＭＭＴ−ＴＬＶ方式で多重された第１の信号と前記ＭＨ−ＣＤＴ（MH-Common Data Table）とを受信する受信部と、
前記受信部で受信した前記ＭＨ−ＣＤＴ（MH-Common Data Table）に含まれている前記第２のtlv_stream_idにより前記信号を識別する識別部と、を有する放送信号送受信装置が提供される。
According to the embodiment
In a broadcast signal transmitter / receiver that transmits / receives multiplex signals by the MMT-TLV method.
The sender is
A transmitter that transmits the signal as a broadcast signal,
A setting unit that sets information on the control signal included in the signal, and
Have,
When the signal is IP rebroadcast among the control signals, the setting unit aggregates the MH-CDT (MH-Common Data Table) separated from the signal and transmits IP multicast separately from the signal. The tlv_stream_id of the MH-CDT (MH-Common Data Table) has the same bit length as the tlv_stream_id and is said to have the same bit length as the tlv_stream_id in order to identify that the signal was included in the signal and transmitted as a broadcast signal when transmitted to the road. Set by replacing with the second tlv_stream_id that identifies the signal,
The receiving side
A receiving unit that receives the IP rebroadcasted first signal multiplexed by the MMT-TLV method excluding the first control information from the signal and the MH-CDT (MH-Common Data Table).
Provided is a broadcast signal transmission / reception device having an identification unit for identifying the signal by the second tlv_stream_id included in the MH-CDT (MH-Common Data Table) received by the reception unit .
