Recommending and activating scenes in a multimedia system are provided. The techniques of the present disclosure can allow the states of the components in the multimedia system to be captured in a scene. Once the scene has been saved, the scene can be activated at a later time. A controller device for recommending scenes by comparing the current state with states of components in saved scenes is also provided. The controller device can also determine if media is playing in a current scene, and activate a selected scene without playing the media content. Once the selected scene is activated, the media playing in the current scene can be switched, and the media playing in the selected scene can be played.

An electronic apparatus is provided. The electronic apparatus according to an example embodiment includes a communication interface and a processor configured to provide a video content and dynamic metadata corresponding to each content section of the video content to an external display apparatus through the communication interface, each content section comprising a plurality of frames, wherein the processor is further configured to transmit the dynamic metadata to the external display apparatus on a frame-by-frame basis, and based on a graphic content being activated, provide data to the display apparatus by converting dynamic metadata corresponding to a content section where the graphic content is activated into static metadata during a plurality of frames.

This technology is to enable high quality audio reproduction on the reception side without supplying a transmission clock using a clock signal line from the reception side to the transmission side. The transmission apparatus receives encoded data capable of clock recovery from a reception apparatus (external device), generates an audio clock on the basis of a carrier clock recovered from the encoded data, and transmits audio data to the reception apparatus in synchronization with the audio clock. The reception apparatus transmits the encoded data capable of clock recovery to the external device in synchronization with the carrier clock generated on the basis of an self-generating audio clock, receives the audio data from the transmission apparatus (external device), and processes the audio data on the basis of the self-generating audio clock.

A data transfer device includes: a video transmission circuit 24, transmitting video data from a first device 10 to a second device 50 during a video period as a timing of transmitting the video data; a transmission part 32, 72, transmitting non-video data between the first device 10 and the second device 50 during a video blanking period as a timing of transmitting the non-video data; and a monitoring part 30, 70, during the video blanking period, controlling the transmission part 32, 72 to stop transmission of the non-video data from the second device 50 to the first device 10 in response to presence of a signal from the first device 10 and stop transmission of the non-video data from the first device 10 to the second device 50 in response to presence of a signal from the second device 50.

The disclosure relates to a 5.sup.th generation (5G) or 6.sup.th generation (6G) communication system for supporting higher data transmission rates. A method by a user equipment (UE) supporting UE estimation-based split rendering is provided. The method includes estimating, at a first time point, a pose of the UE of a second time point indicating a target display time for a first media frame, transmitting the first media frame and first pose information related to the estimated pose to a server, receiving a second media frame, generated by rendering based on the first media frame and the estimated pose, and second pose information associated with the second media frame from the server, and displaying a third media frame at a third time point based on the second media frame and the second pose information.

There is provided a method performed by a device in a network camera system. First and second encoded image data representing the same scene are received (S02, SO4) over a network. The first and the second encoded image data are collected under the same light condition, albeit using different camera parameters. In particular, the second encoded image data is collected using camera parameters which simulate that the second encoded image data is collected under a darker light condition. A ratio of received data amount per time unit of the first encoded image data to received data amount per time unit of the second encoded image data is determined (S06) and the ratio is then used (S08) as an indication of a level of noise in the first encoded image data.
