Abstract
提供一种收发方法、收发装置，用于减少部分TLV流的接收的问题。发送装置具备TLV流提取机构、UDP/IP包提取机构、IP/UDP包分离机构、空包生成机构、以及部分TLV流生成机构，TLV流提取机构接收基于MMT/TLV方式的广播信号并且获取存储有UDP/IP包的TLV流；UDP/IP包提取机构从TLV流中提取UDP/IP包；IP/UDP包分离机构将UDP/IP包分离成包含指定的数据在内的第1UDP/IP包和不包含指定的数据在内的第2UDP/IP包；空包生成机构从第2UDP/IP包中删除UDP/IP有效负载，从而生成仅有UDP/IP头的UDP/IP空包；部分TLV流生成机构至少包含第1UDP/IP包和UDP/IP空包在内地生成部分TLV流；部分TLV流发送机构将部分TLV流向外部装置发送。
