Claim Text:
1. A method of processing broadcast data in a digital television (DTV) transmitter, the method comprising: randomizing enhanced data; first RS encoding the randomized enhanced data; convolutional encoding the first RS encoded enhanced data at a ½ or ¼ code rate; generating first signaling information and second signaling information, wherein the first signaling information and the second signaling information include attribute information of the enhanced data; interleaving the generated first signaling information; multiplexing the interleaved first signaling information and the generated second signaling information and outputting multiplexed signaling information; deinterleaving the convolutional encoded enhanced data and the multiplexed signaling information; second RS encoding the deinterleaved enhanced data and signaling information; interleaving the second RS-encoded enhanced data and signaling information; trellis encoding the interleaved enhanced data and signaling information; modulating a frame including the trellis-encoded enhanced data and signaling information, and transmitting a broadcast signal including the modulated frame, wherein the broadcast signal further includes main data.
