Definitions

  • the system and method for resource allocation of the present invention as utilized in the managing and controlling of streaming from an on-demand server is configured to utilize, for example, a solid state, memory based, on- demand server manufactured by Broadbus Technologies, Inc., under the tradenames B- 1 and SBB-1 , into the operational framework of on demand service operator (ODSO) or other network distribution system with and without the support of a Business Management System (BMS) platform to provide video-on-demand (VOD), subscription video on demand (SVOD), television on demand (TOD), and audio on demand (AOD) services by streaming such content to customers requesting the content.
  • ODSO on demand service operator
  • BMS Business Management System
  • the VOD server 74 begins to stream content and sends it along a Digital Video Broadcast Asynchronous Serial Interface (DVB-ASI, or ASI) 122 to a multiple QAM modulator (MQAM) device 124 such as manufactured by Scientific Atlanta.
  • the MQAM 124 can drive four RF channels 126 from two ASI inputs.
  • Each ASI 122 input carries a single packetized transport stream (SPTS) or multi-packetized transport stream MPTS signal and is identified with a transport stream TSID unique within the management domain, as are the TSIDs for each RF channel 126 output.
  • Each RF output supports a single MPTS (with its own TSID, not necessarily the same as the ASI input TSID), for a theoretical aggregate bandwidth of 42Mbps (256QAM). Streams within the MPTS are disambiguated by MPEG program number.
  • Use Case 4 Mixed environment, the network is a mix of network-managed service groups, server-managed service groups, and server edge-managed service groups, whereby an N2BB, OpenStream on S-A head ends in which several service groups are fed by S-A GQAMs and the remainder are fed by MQAMs.
  • the RA component will follow use cases 1, 2, or 3, depending upon service group configuration.
  • OpenStream and the DNCS can support a mixed environment; and VOD server streaming ports feeding a network-managed service group are switched and on the same subnet or VLAN.
