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.

Specific embodiments of the present invention provide a hydrocracking process for converting low value-added heavy hydrocarbon distillates into high value-added hydrocarbon distillates using a supercritical solvent as a medium.
摘要:
A wireless power transmission controlling apparatus and method are provided. The apparatus includes a power amplifier that receives a source power, amplifies the received source power, and outputs a wireless power transmission signal from the amplified received source power, a band pass filter that filters the wireless power transmission signal, and passes a harmonic wave corresponding to a communication frequency band, and a communication unit that transmits a wireless power transmission control signal using the harmonic wave corresponding to the communication frequency band.
摘要:
A method and apparatus for processing a video frame is provided. The method includes dividing the video frame into pixel blocks each including a reference pixel; calculating difference values between the reference pixel and pixels neighboring the reference pixel; converting the calculated difference values into values that belong to a bit depth range; and performing entropy coding by using the converted difference values as symbols.

Provided is a method and apparatus for compression encoding/decoding an image based on the repetition of an access unit and the repetition of a residual value.
摘要:
Provided are methods and apparatuses for encoding data. One method of encoding data includes generating second data by altering locations of bits within first data to be encoded next based on values of bits within at least one piece of previously encoded data; and entropy-encoding the second data. Also provided are methods and apparatuses for decoding data.
摘要:
A method and apparatus for encoding and decoding an image. The encoding method includes: deciding whether pixel values of a first block of an image are identical to pixel values of a second block of the image that is encoded prior to the first block in a current slice of the image, and determining whether to encode the first block in a first mode according to the deciding; and selectively encoding the first block in the first mode based on the determining, wherein the first mode is a mode for encoding information representing that the first block is encoded in the first mode, instead of encoding the pixel values of the first block, when the first block is identical or similar to the second block.

摘要:
A method and apparatus for encoding/decoding an image, wherein the method includes selecting a predetermined binarization table from a plurality of binarization tables based on prediction values of a current pixel and binarizing or inversely binarizing residual values by using the selected binarization table.
摘要:
A Visible Light Communication (VLC) method in a VLC terminal, in which the VLC terminal requests initial access to an Access Point (AP) on a selected mini-slot among a plurality of mini-slots constituting a control slot, based on control information in a frame, sends an association request to the AP on an allocated uplink time slot, if the uplink time slot allocated to correspond to the selected mini-slot exists in control information in a next frame, and transmits data at a data rate appointed to the VLC terminal included in control information in the current frame using an association Identifier (ID) included in a response received in reply to the association request and the allocated uplink time slot.
