Digital broadcast transmitter, digital broadcast receiver, and methods for configuring and processing streams thereof

Abstract

A method for processing a stream of a digital broadcast receiver is provided. The method which processes a stream that is divided into a first area allocated to first mobile data and a second area allocated to normal data, includes: receiving a transport stream including new mobile data in at least a part of the second area separately from the first mobile data, demodulating the transport stream, equalizing the demodulated transport stream, and decoding at least one of the first mobile data and the new mobile data from the equalized transport stream. Accordingly, mobile data services may be provided in various ways.

AI Technical Summary

Benefits of technology

[0016]Exemplary embodiments provide a digital broadcast transmitter, a digital broadcast receiver, and methods for configuring and processing streams thereof, which utilize a packet allocated to normal data on a transport stream in various ways, thereby diversifying transmission efficiency of mobile data and also improving reception performance of the transport stream.

Problems solved by technology

The area “B” is relatively susceptible to an error compared to the area “A”.

According to the related-art ATSC-MH standard, the known data is not placed in the area “B” and, thus, the area “B” is susceptible to an error.

Also, if the stream is configured as shown in FIG. 1, there is a limit in transmitting the mobile data.

In other words, although an increased number of broadcasting stations and apparatuses support broadcasting services for mobile apparatuses, stream transmitting efficiency deteriorates due to the stream configuration as shown in FIG. 1 in which a portion allocated to normal data cannot be used.

However, it is understood that an exemplary embodiment is not required to overcome the disadvantages described above, and an exemplary embodiment may not overcome any of the problems described above.
