An electronic device according to an embodiment of the disclosure includes: a memory, and a processor electrically connected to the memory, wherein the memory stores a high dynamic range image and dynamic metadata including dynamic tone mapping information corresponding to a plurality of frames included in the high dynamic range image, and wherein the memory stores instructions that, when executed, cause the processor to: control the electronic device to transmit a packet including data obtained by combining one frame among the plurality of frames and a part of the dynamic metadata corresponding to the one frame among the dynamic metadata to an external electronic device in response to an image request from the external electronic device.

Broadcast In-Home Streaming

Techniques for broadcast in-home streaming are described. In some embodiments, the method is performed at a gateway device. The gateway device demultiplexes a broadcast stream to a plurality of streams, including a first stream and a second stream and anchors a first presentation time range of a first segment based on a random access point in the first stream and a first frame in the second stream. The gateway device also identifies one or more frames in the first stream based on presentation timestamps and decoding timestamps of a last frame in the first presentation time range and a first frame in a second presentation time range. The gateway device further captures frames from the second stream within the first presentation time range and generates the first segment having the first presentation time range, including the random access point, the one or more frames, the first frame, and the frames.

A screen mirroring receiving device capable of receiving mirroring streams comprising audio-visual data, the mirroring streams conforming to different vendor-provided screen-mirroring protocols, and capable of processing the mirroring streams for audio-visual rendering.

DECRYPTION AND VARIANT PROCESSING

A plurality of byte ranges forms a sample for content output from a player device, and includes at least one double-encrypted byte range. The plurality of byte ranges is stored in a secured memory, and the at least one double-encrypted byte range is partially decrypted to generate at least one decrypted singe-encrypted byte range. The plurality of byte ranges is stored in an unsecured memory using the at least one decrypted single-encrypted byte range in place of the at least one double-encrypted byte range.

SENSING BASED AUDIO SIGNAL INJECTION
20210176517 · 2021-06-10 ·

Processing circuitry of a connectivity device can receive an audio video signal from a first source. The processing circuitry can also receive an audio signal from a second source. The processing circuitry can transmit the audio video signal to a sink device. When an audio level from the second source exceeds a threshold, the processing circuitry can send the audio signal from the second source along with the video signal from the first source to the sink device.

METHOD AND DEVICE FOR ADJUSTING VIDEO PLAYBACK SPEED
20210142825 · 2021-05-13 ·

Disclosed is a method and apparatus for adjusting a playing speed of a video. The method for adjusting a playing speed of a video includes: after detecting a playing speed adjustment instruction of a target video, determining a target playing speed corresponding to the playing speed adjustment instruction; determining an initial frame rate of the target video, and taking the product of the initial frame rate and the target playing speed as a target parameter of the target video; processing the target video based on a preset frame number adjustment rule corresponding to a target comparison relationship; and adjusting timestamps of video frames contained in the processed target video, based on the preset target frame rate, so that the adjusted target video is played in the preset target frame rate. By applying the present solution, the adjusted target video can be played in the preset target frame rate, thus improving the display quality of the video whose playing speed has been adjusted, and improving the user experience.

METHOD AND DEVICE FOR PROVIDING AUDIO/VIDEO CONTENT TO A RENDERING DEVICE

The present document describes a method (500) for providing combined audio and video content from a source device (210) to an audio sink device (230) and to a video sink device (220). The method (500) comprises determining (501) latency information regarding the video latency for processing the video content and the audio latency for processing the audio content of the combined audio and video content along the device chain (100) between the source device (210) and the audio and video sink devices (220, 230). Furthermore, the method (5009 comprises delaying (502) the audio content or the video content in dependence of the latency information, and providing (503) the combined audio and video content with the delayed audio content or the delayed video content.
