Abstract: This paper presents a software design of stream transmission with respect to an equipment which is critical to deploy Internet TV service on broadband IP network. It implements IPv4/v6 dual-stack stream transmission on DVB-IP gateway. This software design is based on the vxWorks, a RTOS of WindRiver. The implementation is independent of the address protocol families and can be ported at ease.

Key words: DVB-IP gateway, VxWorks, IPv4/IPv6 dual-stack, Socket
