Abstract
Systems and methods for allocating bandwidth in a switched digital video (SDV) system based on channel interest. In some embodiments, bandwidth is deallocated from channels and allocated to requested channels having a higher interest. Tiered approaches for allocating bandwidth are disclosed. Embodiments in which QAMs are allocated across services in a multi-service system based on interest are also disclosed. Embodiments for accommodating emergency access system (EAS) functionality in a SDV system are also disclosed.
