摘要： In the conventional content, a minimum access unit of the random access information is one frame unit. In the case of SVC video content, one frame consists of a plurality of scalable layers. The SVC data can be used for each salable layer only when the data is accessible for each scalable layer. The present invention provides a method and apparatus for transmitting and receiving an SVC file for each scalable layer wherein the SVC file can be accessed for each scalable layer by allowing metadata to contain a layer descriptor in a network abstraction layer unit (NALU) or in a byte unit.

摘要： A server and a terminal enabling channel capacity estimation in a High-Speed Downlink Packet Access (HSDPA) network and a method of controlling the server and the terminal are provided. More particularly, when transmitting data between both terminals in an HSDPA network, a server end may transmit a packet pair of the same size and a client end may measure a time difference between the packet pair and thereby proceed filtering. Through this, it is possible to estimate the channel capacity. Therefore, it is possible to prevent data transmission from exceeding the channel capacity in the HSDPA to thereby prevent a packet loss and to effectively use a channel.

摘要： A method of sharing data of a scalable video coding (SVC) file and the SVC file are provided. The SVC file includes: a scalable base track including at least one scalable layer entry each storing metadata of the at least one scalable layer; and at least one sub track generated based on the scalable base track, which includes identification information of the scalable layer that is a basis of generation of a sub track among the scalable layers and identification information of the scalable base track instead of the scalable layer entry. Accordingly, when an SVC coded content is stored as a file, it is possible to reduce a storage capacity by avoiding duplication of common data and to provide convenience when the stored content is reprocessed by allowing a relation of tracks correlated to one another to be represented.

摘要： The present invention relates to a power amplification circuit of a mobile device for improving the efficiency and the linearity properties of the power amplifier. In one embodiment, the power amplifier improves these properties by controlling the input voltage of the supplemental amplifier so that the power amplifier operates as the Doherty mode in the low output power mode depending on the magnitude of the output power from the output unit and so that the input voltage of the supplemental amplifier may be increased up to satisfy the non-linear operational requirements of a power amplifier in the high output power mode. Moreover, because only the input voltage of the supplemental amplifier is controlled, the power amplifier can be implemented in a simple manner. Thus, the size of the power amplifier becomes small, which in turn reduces the cost of the power amplifier, among other things.
