Signalling for digital broadcasting system |
摘要 |
A method and apparatus for transmitting a plurality of data streams in a wireless broadcast system are provided. The method includes mapping the plurality of data streams onto a super-frame that includes a plurality of frames; inserting signalling information in a first signalling information field for assisting in the reception of a first number of said plurality of data streams for a given frame, the first number being less than or equal to a limit applicable to each of the plurality of frames; dependent on a number of data streams for the given frame being greater than the limit, inserting signalling information in a second signalling information field; inserting said first and second signalling information fields in a preamble section of said given frame; and transmitting the plurality of frames. |

1. A method of transmitting data that includes a plurality of data streams in a wireless broadcast system, the method comprising:
mapping the plurality of data streams onto a super-frame that includes a plurality of frames, each frame including a preamble section and a data section, the preamble section and the data section being time-multiplexed, the data section carrying at least parts of said plurality of data streams, and the preamble section carrying at least signalling information; inserting signalling information in a first signalling information field for assisting in the reception of a first number of said plurality of data streams for a given frame, the first number being less than or equal to a limit applicable to each of the plurality of frames, and the first signalling information field being of a size that is the same for each of the plurality of frames; dependent on a number of data streams for the given frame being greater than the limit, inserting signalling information in a second signalling information field that assists in the reception of further of said plurality of data streams for the given frame, the second signalling information field being of a variable size; inserting said first and second signalling information fields in a preamble section of said given frame; and transmitting the plurality of frames. |
