摘要： An apparatus and a method for composing a subchannel in a wireless communication system are provided. The method includes performing a subband-based permutation on resources for composing a subchannel; selecting one or more subbands as resources for a band selection subchannel from the resources passing through the subband-based permutation; composing the band selection subchannel using at least one of the selected subbands; performing a resource allocation unit based permutation on resources not selected for the band selection subchannel; composing a resource allocation unit based diversity subchannel using subband remained in the selected subbands after the band selection subchannel is composed and at least one of the resource allocation units of the resources passing through the resource allocation unit based permutation; and composing a tone-based diversity subchannel by performing a tone-based permutation on resources remained after the resource allocation unit based diversity subchannel is composed.

摘要： A method and apparatus for transmitting compressed video content are provided. The method includes transmitting a codec selection request frame, the codec selection request frame including an identifier of one or more codecs to be used to compress video content and requesting approval of the use of the codec, receiving a codec selection response frame, the codec selection response frame including result information indicating whether the use of the codec is approved, and transmitting video content frames for the video content compressed by the approved codec based on the codec selection response frame. Each video content frame includes frame type information indicating a type of compression applied to the video content included in the video content frame.

摘要： A wireless packetization apparatus for transmitting and/or receiving multimedia data including video data in a radio transmitting/receiving system, and a method thereof are provided. According to the present invention, error resilience can be increased by adding error protection codes to one portion and a plurality of portions of multimedia-related header information, respectively, when multimedia data such as video data requiring real time or low delay are transmitted and received in a wireless environment, and a packet drop rate can thereby be reduced. Also, information can be more precise recovered by inserting length identifier and length information on an information region into the header.

摘要： A wide band radio transmission method for transmitting bit streams of a video-related application through a radio channel is provided. The wide band radio transmission method comprises the steps of: (a) obtaining identification information on a video-related application which is executed in a user layer, from the user layer; (b) obtaining information on at least one of channel characteristics and a decoding state from a physical layer; and (c) deciding on a quality of service (QoS) level with reference to the identification information and the information on at least one of the channel characteristics and the decoding state from the physical layer. The wide band radio transmission method can efficiently support video-related applications such as applications of H.324M standard, H.323 standard, H.320 standard, and MPEG-4 standard. Also, negotiations on video services having different quality of service (QoS) levels can be performed, and then, optimum video services considering channel characteristics can be provided.
