Abstract
System and method for partitioning data on a SCDMA cable network use methods of creating data streams to transmit to a head end. Further, the data streams transmitted to the head end are coded with fine granularity scalability features and contain divisions which are assigned codes based on predetermined criteria, so that in the event certain assigned codes are interrupted from service, all appliances along the network can be serviced without interruption.
Claims10
A method for partitioning information on a cable network, including one or more appliances and data associated with each transmitting appliance, wherein the associated data comprises a bit rate and a frame length, said method comprising:
- creating a source stream, corresponding to each transmitting appliance and representing a continuous form of the associated data, containing at least one segment, wherein each segment is associated with one of the transmitting appliances and is assigned a code indicating a predetermined level of importance;
- creating a partition stream, corresponding to each segment, containing at least one block, wherein each block represents an amount of time in relation to the bit rate and frame length of the associated data;
- and
- creating a code stream, corresponding to each block with the same assigned code, and containing at least one coded frame, wherein each coded frame represents an amount of time to process one block from every source stream.
A system for partitioning information on a cable network, wherein the cable network includes one or more appliances and data associated with each transmitting appliance, wherein the data comprises a bit rate and a frame length, said system comprising:
- means for creating source streams, corresponding to each transmitting appliance and representing a continuous form of the associated data, containing at least one segment, wherein each segment is associated with one of the transmitting appliances and is assigned a code indicating a predetermined level of importance;
- means for creating partition streams, corresponding to each segment, containing at least one block, wherein each block represents an amount of time in relation to the bit rate and frame length of the associated data;
- and
- means for creating code streams, corresponding to each block with the same assigned code, and containing at least one coded frame, wherein each coded frame represents an amount of time to process one block from every source stream.
