Abstract: Systems and methods for updating firmware in an audio device, such as a soundbar, operatively connected to a Smart TV, are shown and described. Firmware update data is transmitted to the audio device via an audio return channel (ARC) of an HDMI cable. In certain of the systems, the firmware update data is transmitted to the audio device when no audio is being transmitted to or played by the audio device. In other systems, the firmware update data and real-time audio data are multiplexed by the Smart TV and are sent to the audio device via the audio return channel for subsequent demultiplexing and playback of the audio.

Abstract: Methods, apparatus, systems and articles of manufacture are disclosed to monitor streaming media. An example apparatus includes memory, instructions in the apparatus, and processor circuitry to execute the instructions to: calibrate video data based on audio data, the video data and the audio data associated with a media stream, generate a signature representative of the media stream based on the calibrated video data, compare the signature to a signature database to identify a matching signature in the signature database; and credit media corresponding to the matching signature as being viewed.

Abstract: A transmitting method according to one aspect of the present disclosure includes transmitting video control information for reproduction of video data having an individually reproducible unit, transmitting the video data, determining a transmission order of audio control information for reproduction of audio data in a reproduction interval corresponding to a reproduction interval of the video data in such a way that the audio control information is transmitted after the video control information, and transmitting the audio control information according to the determined transmission order, and transmitting the audio data. Thus, in the receiving apparatus, a delay time from reception of data to reproduction of video and audio is shortened.

Abstract: Virtual Reality (VR) processing devices and methods are provided for transmitting user feedback information comprising at least one of user position information and user orientation information, receiving encoded audio-video (A/V) data, which is generated based on the transmitted user feedback information, separating the A/V data into video data and audio data corresponding to a portion of a next frame of a sequence of frames of the video data to be displayed, decoding the portion of a next frame of the video data and the corresponding audio data, providing the audio data for aural presentation and controlling the portion of the next frame of the video data to be displayed in synchronization with the corresponding audio data.

Abstract: A magnetic tape cartridge includes: a magnetic tape on which data is recorded; and a recording medium other than the magnetic tape, and on which a keyword for searching the data recorded on the magnetic tape is recorded.
