A communication connecting method between nodes through a network, includes: storing communication connection information acquired through searching for communication entities of other nodes; determining whether communication connection information on a communication entity of a connection target node exists by searching for the stored communication connection information; and configuring communication connection with the communication entity of the connection target node based on the determination result.

Node and communication connecting method between nodes

A node constituting data distribution service (DDS) structure according to an exemplary embodiment of the present invention includes a first DDS application including a first DCPS layer and a first real-time publish-subscribe (RTPS) layer and a second DDS application including a second DCPS layer communicated with the first RTPS layer.

DDS structure with scalability and adaptability and node constituting the same

Provided are a coded block pattern (CBP) estimating method which is performed using an average value and a dispersion value between blocks of CBPs in a moving picture encoder for IP-TVs (Internet Protocol-Televisions), and a block mode decision method, which can determine all block modes with only the first 16&#xd7;16 block. Accordingly, since an additional operation for mode determination is not necessary, an amount of calculation and thus a calculation time can be remarkably reduced.

Method of estimating coded block pattern and method of determining block mode using the same for moving picture encoder

The present invention relates to a half-pel motion estimation method. The calculation object half-pel, which is in the block of the previous or next reference frame, is not estimated additionally for each block of the current frame divided into blocks of a predetermined size. The present invention suggests an algorithm that can perform half-pel search only with a SAD value used in integer-pel search and a random variable for correcting errors. Since the present invention does not have to generate half-pel for motion estimation, the calculation amount is amazingly reduced and the calculation time is reduced.

Fast half-pel searching method on the basis of SAD values according to integer-pel search and random variable corresponding to each macro block
