AppearTV, a global leader in next-generation broadcast and IP television front-end solutions, has announced the launch of the industry's most advanced IP seamless switching technology. This new seamless switching, utilizing switches, monitors packet loss and switches between two independent ring multicast networks. This enhances the monitoring network while maintaining the integrity of the original data, as the two networks are independent and thus not subject to the same degradation, such as packet loss, at exactly the same time, thanks to the new "reconstruction" feature. Additionally, AppearTV's advanced "packet reconstruction" technology allows operators to reduce overhead for FEC while maintaining robust transmission QoS. This new technology addresses the challenges posed by FEC not effectively handling long bursts of errors in network news, particularly under good conditions.
“AppearTV's seamless redundant switching offers two major benefits to a wide range of network operators: it enables seamless IP network selection and executes packet reconstruction, allowing us to significantly enhance service quality while improving bandwidth efficiency,” said AppearTV CEO Karl Walterholst. “I am pleased that our engineers' creativity has developed a solution that provides a truly win-win scenario for IP video transmission in the broadcast television industry.” This new seamless switching technology can be utilized as long as there is an IP interface on the AppearTV front-end chassis. Its primary purpose is within core IP networks, where most are fully redundant designs; it can also be deployed by cable, satellite, and terrestrial operators using IP-based distribution regional and edge network sites or IP backhaul services.
Advanced features of AppearTV front-end modules include:
■ Central, regional, and edge network capabilities for front-end wired, terrestrial, satellite, and IP-based delivery network solutions
■ Fully integrated, universal modular platform architecture allowing operators to customize and expand the front-end, taking into account operators' needs today and tomorrow
■ Rich I/O signal interfaces, powerful transport stream processing capabilities, and redundancy
■ High-density decoding and descrambling redistribution and routing services
■ Order and high-capacity IP stream modulation for all operators
■ Broadcast-grade quality, high channel density multi-format transcoding and encoding
■ Multi-level redundancy, hot-swappable functionality integrated into 1 or 4RU telecom-grade chassis incorporating a network-based control interface
