The apparatus may include: a layer selection unit to select at least one quality layer from a plurality of quality layers contained in each of spatial layers of the SVC bitstream; a layer discarding unit to discard the at least one quality layer; and a layer dependency modification unit to modify a quality layer dependency between one or more quality layers remaining among the plurality of quality layers, or a spatial layer dependency between the plurality of spatial layers. Accordingly, it is possible to adapt the SVC bitstream where the entire quality of spatial layers is enhanced.

    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.
