Design And Implementation Of Bi-Directional DVB Module Based On Broadcom Chip Intelligent Gateway

With the rapid development of information technology and digital TV industry, cable television operators are facing many challenges. As for the cable television operators’ competitors, telecom operators are actively piloting and promoting IPTV business, internet operators and large internet companies are actively promoting Over The Top(“OTT”) Direct Broadcast Service business, which both have great threaten on the traditional direct broadcast service and Video on Demand(“VOD”) service businesses of cable television operators. How to deal with these challenges, in consolidating the basis of the original business users and obtaining the new business growth point, require how cable television operators can provide variety differentiated services to end users.Network technology, especially the development of mobile Internet technology, enlarged applicable network carrier and the promotion of large bandwidth indoor network strategy, enable intelligent information services to enter into home. This brings huge opportunity to the cable television operators. Through Smart Home services, family members use the smart remote control, mobile phone, PAD and other terminals to achieve interactive communication, to enjoy convenient, efficient, smart and safe home life. Smart home, integrated with the Internet, computing, network communication, sensing and control, multimedia technology, and intelligent home gateway as wisdom of family services in the core processing equipment plays an vital role.Based on the above ideas, we have developed a smart home gateway based on 3330+3383 Broadcom chip. The gateway breaks the traditional set-top boxes and routers philosophy, it bundle the mobile phone, PAD, computer and other network terminal equipments into the home network which share information resources through the home network and the Internet. At the same time in the family through USB, RJ45, Bluetooth, ZigBee, HDMI multiple interfaces to access to the set-top box, intelligent home appliances and one machine, multimedia player, audio and other equipment to realize the seamless connection and communication, realizes the family interior information resources sharing and sound video information integrated. In addition, the gateway also supports the distribution of video resources, voice and video communication and information appliance control functions of different terminals.
