Data processing apparatus, data processing method, and program

Abstract

The present technology relates to a data processing apparatus, a data processing method, and a program capable of achieving reduction in costs of a reception device that receives a GSE packet. A GSE-Lite packet construction section constructs GSE-Lite packet including GSE-Lite signaling, which is signaling for identifying whether data is the GSE-Lite packet in a data link layer of an open systems interconnection (OSI) reference model, by using, as a target, only a protocol data unit (PDU) whose maximum size is limited to a predetermined limit size of 4096 bytes or less, where the GSE-Lite packet is a generic stream encapsulation (GSE) packet having the PDU placed in a data field. The present technology can be applied to, for example, a case of transmitting the GSE packet and a case of receiving the GSE packet.
