Utility
Method and Device for Switching Media Service Channels
3 Jun 21
Embodiments relate to a method and a device for switching media service channels, which minimize the time required to detect the first I frame for a switch channel by utilizing a caching server when switching channels in an IP-based media service, such as IPTV, and at the same time, minimize the time required for synchronization by changing time information in caching information transmitted from the caching server, such that channel switching between media service channels can be performed more quickly.

Utility
Method and Apparatus for Encoding and Decoding Video Using Skip Mode
27 May 21
A video encoding apparatus includes: an inter prediction unit to determine a motion parameter of a current block and generate a predicted block of the current block, by performing a motion estimation on the current block; and an optimal mode determining unit to set a prediction mode of the current block as a SKIP mode when (i) the motion parameter of the current block is identical to a motion parameter of a candidate block among a plurality of candidate blocks and (ii) all-zero coefficients result from a transform and a quantization performed on a residual data block representing the difference between the current block and the predicted block.

Utility
Method and Device for Encoding or Decoding Video
13 May 21
Disclosed herein is a method for decoding a video including determining a coding unit to be decoded by block partitioning, decoding prediction syntaxes for the coding unit, the prediction syntaxes including a skip flag indicating whether the coding unit is encoded in a skip mode, after the decoding of the prediction syntaxes, decoding transform syntaxes including a transformation/quantization skip flag and a coding unit cbf, wherein the transformation/quantization skip flag indicates whether inverse transformation, inverse quantization, and at least part of in-loop filterings are skipped, and the coding unit cbf indicates whether all coefficients in a luma block and two chroma blocks constituting the coding unit are zero, and reconstructing the coding unit based on the prediction syntaxes and the transform syntaxes.
