Abstract: A device and a method for transmitting hierarchically-coded contents adaptively are provided to transmit the contents seamlessly based on a TCP(Transmission Control Protocol) by adaptively transmitting the contents, which are encoded by using an encoding technique having a flexibly hierarchical structure based on the TCP. A decoding rate measurer(11) measures a transmission rate of contents and a contents decoding rate of a terminal. A connection manager(12) performs TCP connection and manages the TCP connection transmitting the current contents. A contents transmitter(14) transmits the contents by changing an A/V(Audio/Video) level of the transmitted contents. A transmission controller(13) compares the decoding rate with the transmission rate, enables the connection manager to adjust the number of TCP connections, and enables the contents transmitter to adjust the A/V level depending on a comparison result. The transmission controller enables the connection manager to remove one TCP connection when more than two TCP connections are found and enables the contents transmitter to increase one A/V level of the transmitted contents when one TCP connection is found if the transmission rate is higher than the decoding rate.

Abstract: A method for transmitting and receiving an SVC(Scalable Video Coding) file by a scalable layer unit and an apparatus therefor are provided to form a layer descriptor of an NALU(Network Abstraction Layer Unit) and a byte unit in meta data and access the SVC file by the scalable layer unit. An SVC transmission layer determining unit(510) determines a transmission scalable layer to be transmitted to a network among at least one or more scalable layers included in respective frames of media data of an SVC file on the basis of application level information collected from the network to determine an application degree of scalable coding. An SVC application transmission unit(500) extracts the transmission scalable layer from the media data of the SVC file and transmits a generated bit stream through a layer descriptor indicating access information of at least one or more scalable layers used in the respective frames of the SVC file.
