Apparatus and methods for utilizing variable rate program streams in a network

摘要: Apparatus and methods for transparently using otherwise wasted bandwidth associated with variable-rate program streams to deliver additional content. In one embodiment, the network comprises a broadcast switched architecture (BSA), are loaded up target rate “null” packets then delivered over infrastructure plurality of hub sites. The unloaded reproduce original variable streams, vacated by removal null used as transport mechanism (e.g., non time-sensitive) content be subscribers. process can also substantially automated anticipatory (through, e.g., transmission bit insertion data downstream). invention advantageously implemented minimal modifications existing infrastructure, supports business operational supervisory processes. Network server, QAM modulator, CPE apparatus implementing aforementioned methodologies disclosed.
