Broadcom push "channel bonding" cable TV set
Message -2,006 on January 9-Broadcom Corporation (Nasdaq BRCM), a wired and wireless broadband communications Semiconductor The world's leading products, today announced industry-first integrated channel bonding technique Cable television STB Front-end chip. Channel bonding is a DOCSIS ® 3.0 capabilities, can significantly increase the transmission rate of cable TV network, and allow multi-service Operation Operators (MSO) to move to full IP network platform. Addressing voice, video and data communications requirements of all IP network for multi-service operators to offer more benefits, such as increasing the cable television and local Broadcasting The number of channels, content flexibility and improved network efficiency.
Channel bonding technology can be several DOCSIS channels together to provide more than today's cable Modem Much higher data rates. Today's announcement is the new Broadcom ® set-top box chip, chip Set Become a channel bonding technique. The new chip can support up to 120 megabits per second (Mbps) downstream data rates, enabling next generation media center to support an all IP network platform, such as Comcast's RNG family of devices. For voice, video and data content transfer to full IP platform multi-service operators to reduce network operating costs, while enabling the network to support high-speed high-resolution video downloads, high bit rate services and other IP for voice and video services.
"Increase the speed and performance of the cable network's capacity for multi-service operators is a key factor, as more and more Telecommunications Operators install fast, 'Fiber to the curb' network, "Broadcom's Broadband Communications Sector DanielMarotta senior vice president and general manager, said," We launched a new cable TV set-top box chip sets a new benchmark for the industry, enabling multi service operators operators are now able to support the transition to an all IP network to deploy the new set-top boxes and media center. "
"Channel bonding technology to allow Comcast to continue to shift to the IP platform, a key technology," ComcastCable's chief technology officer ( CT O) DavidFellows said, "will channel bonding technology into chips, as Broadcom's solutions, is moving to DOCSIS and IPTV Ability to combine an important step in this direction. "
Broadcom's new BCM3255 set-top box chip design and BCM7400 dual high-definition (HD) advanced video coding (AVC) / VC / MPEG -2 Decoder chips. The BCM7400 also announced today, is to support the latest Video Compression Single-chip back-end technology solutions, including for high-definition programming Make The AVC (ITU and ISO joint standard) and VC-1 (Picture and Television Engineers SMPTE standard, or standard) support.
BCM3255 and BCM7400 BCM3420 tuner with multiple combinations, it can provide manufacturers a complete HDAVC, digital video recording ( DV R), cable TV media center design that can support channel speeds up to 120 Mbps multiple HDAVC streams, advanced downloadable conditional access system (DCAS) security features, up to 1600 DM IPS processing power, and complete Home Networking Management package. Broadcom will be packaged this complete solution into BCM7400CAB reference design, to provide customers with next-generation set-top box design of integrated solutions.
Products BCM3255 is a cable TV set-top boxes and apply HDDVR highly integrated media center front-end chip. The chip integrates three 1024/256QAM-band demodulator, one-of-band demodulator, DOCSIS2.0 + / 3.0 cable modem technology, USB 2.0MAC and PHY, and a 10/100 Fast Ethernet Network MAC (media access controller) and PHY (physical layer device). 800DMIPS chip integrated processor provides support for a number of next-generation features, including DOCSIS2.0 + / 3.0 and channel bonding resequencing, DOCSIS set-top gateway (DSG) protocol, and support for TCIP, IpnP and IPv6 Network protocol.
BCM3255 set-top box chip can be configured in the current video channels or in a channel bonding mode. Cable engineers, developed by Broadcom software can remotely switch between the two modes, making the chip ideal for both broadcast solutions used in current, but also for the future of the channel bonded networks based on IP .
Price and supply capacity BCM3255 can sample quantities now. This chip is a 416-pin PBGA package, 10,000-volume and is priced at 32 U.S. dollars per tablet.
