Abstract: The present invention relates to a method and apparatus for transmitting digital broadcasting signals and a method and apparatus for receiving digital broadcasting signals that divide a stream into a plurality of layers according to characteristics of the stream, that independently process the layers, and that dynamically allocate frequencies on the basis of the processed signals. A method of transmitting digital broadcasting signals includes dividing a single stream into a plurality of layers according to characteristics of the stream; performing encoding and mapping on each of the layers; and dynamically allocating a frequency to each of the layers on the basis of the number of symbols for each layer.

Abstract: In a terrestrial DMB, a transmitting apparatus multiplexes a plurality of service streams generated for any service to a plurality of ensembles. In this case, the same sending time data is constructed in a time stamp field of each frame for each of a plurality of ensembles. With this configuration, a plurality of transmitting apparatuses can send a plurality of transmission frames including service streams for the same service at the same point of time, and thus receiving apparatuses can actually receive a plurality of transmission frames at the same point of time.

Abstract: A method and apparatus for encoding and decoding three-dimensional mesh information are provided. The method and apparatus separately encode/decode order information of elements, such as vertices and faces, of a three-dimensional mesh model (original model) in consideration of a change in an element order during encoding three-dimensional mesh information for the original model. The method for encoding three-dimensional mesh information includes the steps of: encoding the three-dimensional mesh information and outputting an encoded bit-stream; calculating order information of at least one element in an original model contained in the three-dimensional mesh information; encoding the element order information; and generating packets of the encoded bit-stream, wherein the encoded element order information is inserted into the packet.
