Apparatus and method for transmitting hierarchically multimedia data TS to prevent jitter of timing information and for recovering the multimedia data TS |
摘要 |
An apparatus and a method for transmitting multimedia transport stream hierarchically and recovering the multimedia transmission stream are disclosed. The apparatus includes: an input matching unit for dividing the multimedia data transport stream into packets; a sequence number inserting unit for inserting a sequence number to the packet; an error check code (ECC) inserting unit for inserting an ECC to the sequence number inputted packet, to thereby generate a user packet; a layer information storing unit for storing layer information for the user packet; a layer dividing unit for dividing the user packet; a layer storing unit for storing the divided user packet in each layer; and a hierarchical framing and transmitting unit for generating a hierarchical transport frame by combining a predetermined number of the user packets with the layer information, and transmitting the hierarchical frame in a different transmission method for a different layer.
