Each SPTS is transmitted as a series of groups of a predefined number of transport stream packets. An input buffer that receives the packets is configured to hold only the predefined number of packets at any point in time. A table builder receives packets from the input buffer and assigns a set of unique packet identifiers to the packets from each SPTS, reconfigures each program map table in the packets, and generates a program association table for a multiple program transport stream (MPTS). The table builder retains unaltered the program clock reference in the data packets. A first-in, first-out buffer combines packets received from the table builder into a MPTS. An output stage modulates a carrier signal, such as for a television channel, with the MPTS."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Digital video apparatus for multiplexing single program transport streams into a multiple program transport stream","description":"An apparatus for transporting digital multimedia receives signals for a plurality of single program transport streams (SPTS).
