VILLAGEFLOW

Digital broadcast multiprocessing software

“VILLAGEFLOW” is versatile and flexible software tailored for the operation and development of digital broadcast signal (TS) processing systems. It provides an integrated platform for building TS systems by combining a variety of input/output and broadcast processing functions for digital broadcast signals (TS). This enables the construction of affordable, high-quality broadcast equipment that was previously unattainable, while also making it possible to implement experimental broadcasts and new broadcast services. Supporting various ARIB encoding processes, VILLAGEFLOW is compatible with modulation outputs for ISDB-T and ISDB-S, as well as data broadcast and EPG generation, one-seg services, and global standards like DVB and ATSC.
