    Abstract: A device and method for transcoding digital audio/video streams. Only the video data, from among audio/video data provided in the form of compressed digital streams such as TV broadcast streams, is transcoded, and then the transcoded video data is synchronized with the audio data. To synchronize the transcoded video data with the audio data, original Presentation Time Stamps (PTSs) of the video data before the transcoding are used for the transcoded video data, or new PTSs are used for the transcoded video data and PTSs of the audio data are updated based on the new PTSs. The transcoding and PTS synchronization is performed on the basis of sections having continuous PTS values. Accordingly, degradation of sound quality due to unnecessary audio data transcoding is avoided, while preventing synchronization mismatching between the audio and video data in the transcoding procedure.

    Abstract translation: 一种用于对数字音频/视频流进行代码转换的设备和方法。 只有以诸如电视广播流之类的压缩数字流的形式提供的音频/视频数据中的视频数据被转码,然后转码的视频数据与音频数据同步。 为了将经代码转换的视频数据与音频数据同步,代码转换之前的视频数据的原始演示时间戳(PTS)用于代码转换的视频数据,或新的PTS被用于代码转换的视频数据,音频数据的PTS是 基于新的PTS进行更新。 基于具有连续PTS值的部分执行代码转换和PTS同步。 因此,避免了由于不必要的音频数据代码转换引起的音质的劣化,同时防止了代码转换过程中的音频和视频数据之间的同步失配。

    Abstract: The semiconductor light-emitting element includes a light-emitting portion, a first electrode under the light-emitting portion, a second electrode on the light-emitting portion, a passivation layer surrounding the light-emitting portion, and a first structure surrounding the passivation layer. Since the width is increased by the first structure, the aspect ratio (AR) is reduced, the semiconductor light-emitting element moves without being tilted during self-assembly, so that the assembly defect of semiconductor light-emitting element can be prevented, the assembly rate can be improved, and the assembly speed can be increased.

    Abstract: The present disclosure relates to a time alignment timer handling in wireless communications. According to an embodiment of the present disclosure, a user equipment (UE) may initiate a transmission of failure information for a cell group based on detecting a failure on the cell group. The UE may consider a time alignment (TA) timer related to a TA configuration for the cell group as expired based on initiating the transmission of the failure information. After transmitting the failure information, the UE may receive a configuration for failure recovery of the failure on the cell group. The UE may restart the TA timer related to the TA configuration for the cell group based on receiving the configuration for failure recovery.

    Abstract: An image decoding method according to the present document comprises a step of deriving modified transform coefficients on the basis of an inverse reduced secondary transform (RST) regarding transform coefficients regarding a target block. The inverse RST is performed on the basis of transform sets determined on the basis of a mapping relation following an intra prediction mode applied to the target block, and a transform kernel matrix selected from two transform kernel matrices included in the transform sets, respectively, and and is performed on the basis of whether or not the inverse RST is applied, and a transform index indicating one of the transform kernel matrices included in the transform sets. A syntax element bin string regarding the transform index is decoded on the basis of a different context set according to the tree type regarding the division structure of the target block.

    Abstract: An operation method of a device in a wireless communication system, and a device are provided. The device may be a terminal, a chipset, or a base station. A terminal measures a reference signal in a frequency band configured by a base station, and reports a measurement result to the base station. The terminal may not be able to properly measure a reference signal in the entirety of the configured frequency band. In this case, the terminal operates to omit channel state information reporting for a frequency band in which a reference signal cannot be properly measured. For example, the terminal lowers the priority of the frequency band so that channel state information reporting for the frequency band is omitted.
