Method and apparatus for transmission and reception of data streams in digital video broadcasting systems

Abstract

A method of transmitting data in a wireless communication system is provided. The method comprises mapping service data onto a first set of multiple Physical Layer Pipes (PLPs), mapping the first set of multiple PLPs onto a first set of logical frames, wherein each of the first set of logical frames is of the same size, forming a first logical channel comprising the first set of logical frames, and transmitting the mapped service data over a target delivery system.

What is claimed is: 
     
         1 . A method of transmitting data in a communication system, the method comprising:
 receiving data provided from a service provider;   generating logical frames comprising delivery units for transmitting at least one data stream included in the data; and   transmitting the logical frames on at least one logical channel.   
     
     
         2 . The method of  claim 1 , wherein the generating of the logical frames comprises:
 generating at least one set of the logical frames comprising the first set of the delivery units; and   transmitting each of the at least one set of the logical frames on a different logical channel of the at least one logical channel.   
     
     
         3 . The method of  claim 1 , further comprising:
 grouping logical channels having different logical frames.   
     
     
         4 . The method of  claim 1 , further comprising:
 receiving at least one service requirement of the service provider; and   determining a number for each of the logical frames and a number of delivery units included in each of the logical frames, based on the at least one service requirement.   
     
     
         5 . A method of receiving data in a communication system, the method comprising:
 receiving logical frames transmitted on at least one logical channel from a transmitter; and   decoding the logical frames comprising delivery units for transmitting at least one data stream included in the data.   
     
     
         6 . The method of  claim 5 , wherein the decoding of the logical frames comprises:
 obtaining at least one set of the logical frames comprising a first set of the delivery units,   wherein the at least one set of the logical frames is received on a different logical channel of the at least one logical channel.   
     
     
         7 . The method of  claim 5 , wherein different logical frames are received on each of the at least one of the logical channels. 
     
     
         8 . The method of  claim 5 , wherein a number for each of the logical frames and a number of the delivery units included in each of the logical frames are determined based on the at least one service requirement of a service provider providing the data. 
     
     
         9 . A transmitter for transmitting data in a communication system, the transmitter comprising:
 a receiving unit configured to receive data provided from a service provider;   a controller configured to generate logical frames comprising delivery units configured to transmit at least one data stream included in the data; and   a transmitting unit configured to transmit the logical frames on at least one logical channel.   
     
     
         10 . The transmitter of  claim 9 , wherein the controller is further configured:
 to generate at least one set of the logical frames comprising the first set of the delivery units, and   to control the transmitter to transmit the at least one data stream on a different logical channel of the at least one logical channel.   
     
     
         11 . The transmitter of  claim 9 , wherein the controller is further configured to generate a number of logical channels having different logical frames. 
     
     
         12 . The transmitter of  claim 9 ,
 wherein the receiving unit is further configured to receive at least one service requirement of the service provider, and   wherein the controller is further configured to determine a number for each of the logical frames and a number of the delivery units included in each of the logical frames, based on the at least one service requirement.   
     
     
         13 . A receiver for receiving data in a communication system, the receiver comprising:
 a receiving unit configured to receive logical frames transmitted on at least one logical channel from a transmitter; and   a decoder configured to decode the logical frames comprising delivery units configured to transmit at least one data stream included in the data.   
     
     
         14 . The receiver of  claim 13 ,
 wherein the decoder is further configured to obtain at least one set of the logical frames comprising the first set of the delivery units, and   wherein the at least one set of the logical frames is received on a different logical channel of the at least one logical channel.   
     
     
         15 . The receiver of  claim 13 , wherein the receiving unit is further configured to receive different logical frames on each of the at least one of the logical channels. 
     
     
         16 . The receiver of  claim 13 , wherein a number for each of the logical frames and a number of the delivery units included in each of the logical frames are determined based on the at least one service requirement of a service provider providing the data.
