Time Warner Cable selects BigBand Networks for Houston deployment
December 22, 2003
BigBand Networks, a provider of broadband multimedia platform solutions for broadcast television and on-demand services, announced that Time Warner Cable is completing a digital television system based on its BMR (Broadband Multimedia-Service Router) in its Houston, TX, system.
Time Warner's Houston system passes more than 1.5 million homes and has more than 25 hub sites. BigBand said its professional services organization is collaborating with Time Warner to define and implement the Houston installation.
The system uses BigBand Grooming and BigBand HDTV to determine channel placement of each standard-definition and high-definition video program, while RateShaping is applied to control bandwidth efficiency and video quality. The BigBand Ad Splicing Gateway detects insertion points in the groomed programs for local digital advertising according to the SCTE 35 standard, enabling advertisements to be spliced from servers, with continuing video quality and bandwidth efficiency control.
Programming and advertising content is distributed among Time Warner Cable Houston facilities by the BigBand Transport Gateway, which uses Gigabit Ethernet with video quality assured by de-jitter at hub destinations.
The BigBand BMR's platform intelligence allows any hub location to automatically switch to a redundant source by Gigabit Ethernet transport should its primary source have problems. These problems can range from network resource outages to video quality issues for a single program feed. At the hubs, BigBand Broadcast Edge performs high- density QAM modulation and RF upconversion of the content.
