Abstract
The present technology relates to a data processing device, a data processing method, and a program capable of realizing low cost of a reception device receiving a GSE packet conforming to DVB-GSE. An sGSE packet structuring unit sets, as a target, only a PDU (Protocol Data Unit) of which a maximum size is restricted to a predetermined restriction size equal to or less than 4096 bytes and structures an sGSE packet which is a GSE packet in which the PDU is deployed in a data field and which conforms to DVB (Digital Video Broadcasting)-GSE (Generic Stream Encapsulation). The present technology is applicable, for example, when the GSE packet is transmitted or received.
Claims10
A data processing device comprising:
- circuitry configured to:
- receive a digital video broadcast signal including:
- a first physical layer pipe (PLP) and a second PLP, wherein the first PLP includes a general stream encapsulation (GSE) packet and the second PLP includes a simplified GSE packet having a data field containing a protocol data unit (PDU) of which a maximum size is restricted to a predetermined restriction size equal to or less than 4096 bytes such that the maximum size of any PDU carried by the simplified GSE packet is 4096 bytes and any PDU carried by the simplified GSE packet is carried by the simplified GSE packet without being fragmented, and
- signaling indicating that the first PLP includes the GSE packet and that the second PLP includes the simplified GSE packet, the signaling being in an open systems interconnection (OSI) data link layer or in a lower OSI layer;
- and
- extract the PDU from the simplified GSE packet if the signaling indicates that second PLP includes the simplified GSE packet.
A data processing method comprising:
- receiving a digital video broadcast signal including:
- a first physical layer pipe (PLP) and a second PLP, wherein the first PLP includes a general stream encapsulation (GSE) packet and the second PLP includes a simplified GSE packet having a data field containing a protocol data unit (PDU) of which a maximum size is restricted to a predetermined restriction size equal to or less than 4096 bytes such that the maximum size of any PDU carried by the simplified GSE packet is 4096 bytes and any PDU carried by the simplified GSE packet is carried by the simplified GSE packet without being fragmented, and
- signaling indicating that the first PLP includes the GSE packet and that the second PLP includes the simplified GSE packet, the signaling being in an open systems interconnection (OSI) data link layer or in a lower OSI layer;
- and
- extracting the PDU from the simplified GSE packet if the signaling indicates that second PLP includes the simplified GSE packet.
A non-transitory storage medium configured to store a program causing a computer to function as:
- a reception unit that receives a digital video broadcast signal including:
- a first physical layer pipe (PLP) and a second PLP, wherein the first PLP includes a general stream encapsulation (GSE) packet and the second PLP includes a simplified GSE packet having a data field containing a protocol data unit (PDU) of which a maximum size is restricted to a predetermined restriction size equal to or less than 4096 bytes such that the maximum size of any PDU carried by the simplified GSE packet is 4096 bytes and any PDU carried by the simplified GSE packet is carried by the simplified GSE packet without being fragmented, and
- signaling indicating that the first PLP includes the GSE packet and that the second PLP includes the simplified GSE packet, the signaling being in an open systems interconnection (OSI) data link layer or in a lower OSI layer;
- and
- a PDU extraction unit that extracts the PDU from the simplified GSE packet if the signaling indicates that second PLP includes the simplified GSE packet.
