In one implementation, upon receiving a request for a non-guaranteed channel is received from a subscriber station (e.g., a set-top box or STB), a bandwidth pipe modeling process is operative to model a bandwidth pipe corresponding to each edge QAM device configured to support non-guaranteed channels for selecting a particular edge QAM device that can best accommodate the requested non-guaranteed channel. Bitrates of MABR streams of existing channels of the selected edge QAM device may be adjusted in order to accommodate a particular MABR stream at chosen bitrate of the requested non-guaranteed channel. IGMP Join operations may be effectuated, as needed, to join MABR streams of the existing channels and the requested non-guaranteed channel to correct IGMP group(s). A channel change response message including one or more channel frequencies, if the change request is accommodated, may be transmitted to the requesting subscriber station."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"System and method for providing non-guaranteed channel content in a switched digital video network using multicast ABR streaming","description":"A system and method for providing non-guaranteed channels in a switched digital video network using multicast adaptive bitrate (ABR) streaming.
