    • The writing address supply part 210 supplies writing addresses for writing the bits forming bit sequences corresponding to the header H contained in a frame to be transmitted or stored and bit sequences corresponding to the data D, into the operating memory 220. The reading address supply part 230 alternately supplies to the operating memory 220 a plurality of addresses for reading a plurality of continuous bits corresponding to the header H from the operating memory 220, and an address for reading 1 bit corresponding to the data D from the operating memory 220, and reads the bit sequence such that the bits forming the bit sequence corresponding to the header H are scattered and arranged within the bit sequence forming the data D, from the operating memory. In accordance with such an interleaving device, it is possible to individually randomize frames according to their constituent data, and it is possible to transmit the bits that make up such data in a format which is most suited for said data.
    • 写地址提供部分210将写入地址用于写入与要发送或存储的帧中包含的标题H相对应的位序列的位和与数据D对应的位序列的位写入到操作存储器220中。 读取地址提供部件230从操作存储器220交替地向操作存储器220提供用于读取对应于头部H的多个连续位的多个地址,以及从操作中读取与数据D对应的1位的地址 存储器220,并且读取比特序列,使得形成与头部H相对应的比特序列的比特被分散并布置在从操作存储器形成数据D的比特序列中。 根据这种交织装置,可以根据其构成数据单独地随机化帧,并且可以以最适合于所述数据的格式来发送构成这样的数据的比特。

    • Apparatuses and methods are disclosed herein for implementing dormant mode with paging in a WLAN. Power savings in the computing device and reduction in traffic across the network are achieved by requiring a computing device to inform the WLAN of its location only when it crosses a paging area boundary or is to receive IP traffic. Dormant mode with paging is implemented in a protocol that supports dormant functionality and paging functionality but does not itself provide methods or standards for implementing such functionality, such as the IEEE 802.11. The methods and apparatuses disclosed herein provide the methods needed to implement dormant mode with paging in such a protocol. Generally, the methods and apparatuses for implementing dormant mode with paging basically include (1) establishing paging areas; (2) communicating access group information to a computing device; and (3) locating a computing device.

    • A transcoding apparatus converts first coded data obtained from a plurality of frames forming a video image by means of a coding algorithms including an interframe prediction coding algorithm with motion compensation into second coded data having a different structure. More specifically, the transcoding apparatus takes a portion of frames which have had the interframe prediction coding and are included in the plurality of frames forming the video image as processing object frames, and from at least the first coded data corresponding to the processing object frames, generates the second coded data corresponding to coded data which are to be obtained when performing the interframe prediction coding on the processing object frames with reference to second reference frames which are different from first reference frames referenced in the interframe prediction coding of the processing object frames. In order to the second coded data, the transcoding apparatus has a motion information calculating portion for calculating motion information to be included in the second coded data using at least motion information contained in said processing object data.
