Abstract

The Mobile Broadcasting (A-VSB MCAST) design consists of transport and signaling opt imized for mobile and handheld services. Section 5 provides the overall A-VSB MCAST architecture. Section 6 specifies the physical and link layers. Section 7 specifies the trans port layer. And, Section 8 describes the frame slicing mechanism for burst transmission. Backwards compatibility is ensured by the careful design of the physical and link layers.

Field tests are well underway now, being overseen by ATSC TSG/S9.

Claims

1. (canceled)

2. A digital broadcasting transmitter, comprising:

a deinterleaver which constitutes at least one turbo stream group which is processed to be robust against an error; and

a filtering unit which filters the turbo stream group processed by the deinterleaver in a predetermined format.

3. The digital broadcasting transmitter according to claim 2, further comprising:

an interleaver which generates information to constitute the at least one turbo stream group.

4. The digital broadcasting transmitter according to claim 3, further comprising:

a delay buffer which delays a stream output by the deinterleaver and transmits the delayed stream to the filtering unit.

5. The digital broadcasting transmitter according to claim 4, further comprising:

a stuffer which inserts the filtered turbo stream group into a transport stream.

6. A method for processing a stream in a digital broadcasting transmitter, the method comprising:

performing deinterleaving to constitute at least one turbo stream group which is processed to be robust against an error; and

filtering the turbo stream group in a predetermined format.

7. The method according to claim 6, further comprising:

generating information to constitute the at least one turbo stream group;

delaying the stream processed in the deinterleaving operation; and

inserting the filtered turbo stream group into a transport stream.

8. A digital broadcasting receiver, comprising:

a receiving unit which receives a transport stream comprising a turbo stream group which is processed to be robust against an error;

a demodulator which demodulates the transport stream; and

an equalizer which equalizes the demodulated transport stream,

wherein the transport stream is transmitted from a digital broadcasting transmitter comprising a deinterleaver which constitutes at least one turbo stream group which is processed to be robust against an error, and a filtering unit which filters the turbo stream group processed by the deinterleaver in a predetermined format.

9. A method for processing a stream in a digital broadcasting receiver, the method comprising:

receiving a transport stream comprising a turbo stream group which is processed to be robust against an error;

demodulating the transport stream; and

equalizing the demodulated transport stream,

wherein the transport stream is transmitted from a digital broadcasting transmitter comprising a deinterleaver which constitutes at least one turbo stream group which is processed to be robust against an error, and a filtering unit which filters the turbo stream group processed by the deinterleaver in a predetermined format.
