Abstract: A wide band radio transmission method, apparatus and computer readable medium for transmitting bit streams of a video-related application through a radio channel are 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 the H.324M standard, the H.323 standard, the H.320 standard, and the 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.

Abstract: Provided are a filtering method and apparatus for removing blocking artifacts and ringing noise. The filtering method includes transforming video data on a block-by-block basis, and detecting the presence of an edge region in the video data by checking the distribution of values obtained by the transformation. Accordingly, it is possible to completely remove blocking artifacts and/or ringing noise by more effectively detecting the presence of an edge region in video data.

Abstract: A data transmitting/receiving system adds identifying information to a data packet based on characteristics of the data. The identifying information can be a data type of a payload data of an IP/UDP/RTP packet and/or a temporal data sequence of the payload data. The IP/UDP/RTP packet added with the identifying information is segmented into an IP/UDP/RTP header and IP/UDP/RTP data. The segmented IP/UDP/RTP header and the IP/UDP/RTP data can be transmitted through different channels. A receiver sends retransmission control information based on the added identifying information extracted by the receiver, the retransmission control information providing retransmission time and priority information. A transmitter retransmits reception error occurring IP/UDP/RTP data according to the retransmission control information received by the transmitter. Varying the retransmission times and/or retransmission priority based on the data characteristics, accommodates data retransmission so that data more influential to data restoration in case of loss/damage can be received more stably.
