Abstract:
1. A stream recording apparatus comprising: a receiver side communication module for receiving from a network stream data having a frame assembly identification packet including time information inserted therein on a frame assembly basis, and for outputting the stream data; a plurality of buffers for storing temporarily the stream data output by the receiver side communication module; a buffer assignment unit for storing assignment information indicating a corresponding relationship between a plurality of information delivery apparatuses and the plurality of buffers; a stream sorting unit for determining, based on the assignment information stored in the buffer assignment unit, which of the buffers is to hold the stream data output by the receiver side communication module; a stream selector for causing, according to the determination by the stream sorting unit, the determined buffer to hold the stream data output by the receiver side communication module; a frame assembly extraction unit for reading the stream data from the determined buffer on a frame assembly basis; a frame assembly synchronizing unit for, based on the time information included in the frame assembly identification packet inserted to the stream data, maintaining synchronization between frame assemblies in the stream data read by the frame assembly extraction unit, and for outputting synchronization information for associating frame assemblies of the same time with each other; and a writing unit for recording the stream data read by the frame assembly extraction unit in a recording medium.
