Abstract: An apparatus and a method of sending/receiving video on demand (VOD) streaming service according to providing client-favored advertisement. A VOD server and a VOD client terminal tie the VOD streaming service to client advertisement selection interactions, such as advertisement receipt selections, advertisement selection attributes (e.g., type, mode, etc.). The VOD server comprises a service controller providing to clients multimedia contents and specific advertisement contents selected by the clients to receive and a data storing unit storing the multimedia contents, the advertisement contents, and the client data.

Abstract: A method for transmitting asynchronous data includes including: comparing a size of asynchronous data with that of an empty transmission area; inserting the asynchronous data into the empty transmission area when the asynchronous data has a size smaller than or equal to that of the empty transmission area; determining if the empty transmission area has a size larger than a predetermined threshold value when the asynchronous data has a size larger than that of the empty transmission area; transmitting the asynchronous data with the empty transmission area left when the empty transmission area has a size smaller than the predetermined threshold value; and segmenting the asynchronous data according to the size of the empty transmission area when the empty transmission area has a size larger than the predetermined threshold value, inserting the segmented asynchronous data into the empty transmission area, and transmitting remaining segmented asynchronous data in a subsequent transmission cycle.

Abstract: Disclosed is a method for forming a super frame used for transmitting isochronous data and asynchronous data in a residential Ethernet system. The method includes the steps of receiving the isochronous data and the asynchronous data to be transmitted through the residential Ethernet system, forming an isochronous frame using the received isochronous data, forming a cycle start frame used for reporting start of the super frame, and inserting the asynchronous data into an area of an asynchronous frame by employing a remaining area as the area of the asynchronous frame, the remaining area being obtained by excluding an isochronous frame area, which includes the cycle start frame and the isochronous frame, from an area having the predetermined size.

Abstract: A recombinantly derived insect chitinase gene is inserted into a vector for host expression of the chitinase protein, and may be utilized according to methods for controlling a population of insect pests. A recombinant virus is provided for this purpose, as well as a recombinant plant. Recombinantly derived insect chitinase may also be expressed in host cells or larvae for subsequent purification.
