Abstract


With the development of the appliance digitized appliances Internet constitutes a smart home network , providing people with a more rich and diverse experience . Smart home network through home gateways to easily control the the family internal device networking and information exchange , as well as the external network home facilities . Home gateway via SIP protocol , centralized control of various facilities in the home network to realize VoIP , video surveillance , and digital set-top boxes , and other functions . In this paper, the Wuhan Research Institute of Posts and Telecommunications Fund \high - level signaling control protocol of the respective advantages and disadvantages. Second, a home gateway implementations in development board Huaheng developed HHBF561 design , the program is based on the development board , DSP ARM Open Multimedia Application Platform (OMAP, Open Multimedia Application Platform) architecture in embedded development on the Linux operating system . The paper focuses on cutting operating system and the Linux platform environment Bootloader loaded with programming , audio and video codec module and network environment to build , and Linux Socket function coding , network transmission , and playback of the audio signal . The software debugging Finally and propose future research directions .
