Example techniques involve control of a media playback system involving multiple zones. A control application may include different control interfaces for respective zones of the multiple zones. A control interface for a given zone may include transport controls to control playback in the zone, volume controls to control zone volume level, and an indication of media playing back in the zone. A user may utilize swipe inputs to switch between the control interfaces in order to control different zones.

Example systems and techniques disclosed herein facilitate interoperability between different media playback systems referred to herein as a virtual line-in (VLI) media playback system and a native playback system. When a VLI session is created by a VLI sender, a first native playback device can join a VLI group as a VLI receiver. As a VLI receiver, the first native playback device receives audio content and playback commands from the VLI sender to facilitate synchronous playback with other VLI receivers. At the same time, this native playback device can concurrently operate as a native domain group coordinator of a native domain synchrony group. As the native domain group coordinator, the native playback device translates VLI domain audio, control, and timing signals into the native domain and distributes such signals to native domain group members. In this way, the native domain group members can synchronize their playback with the VLI group.

An XR device and a method for controlling the same are disclosed. The XR device is applicable to 5G communication technology, robot technology, autonomous driving technology, and Artificial Intelligence (AI) technology. A method for controlling the XR device includes executing an electronic appliance arrangement application by a user who uses the XR device, displaying an image of an indoor space of a display screen of the XR device, overlapping an electronic appliance selected by the user with the image of the indoor space, and displaying the overlap result image, and if the electronic appliance is arranged at a specific position of the indoor space and the specific position is improper for arrangement of the electronic appliance, providing the user with an improper notification message including information about why the arrangement position is improper.

According to one embodiment, an electronic apparatus capable of communicating with a second electronic apparatus of a first user, the electronic apparatus, the electronic apparatus includes a receiver, electronic circuitry, a speaker and a transmitter. The electronic circuitry configured to determine whether the sound of the second user is output by the electronic apparatus or the second electronic apparatus, using at least one of an image of around the first user and sound of around the first user. The speaker configured to output the sound of the second user, is output by the electronic apparatus. The transmitter configured to transmit the signal of the sound of the second user to the second electronic apparatus, is output by the second electronic apparatus.

Methods and systems are provided to allow for merchant or third party controlled adjustment of a physical environment around a user. Such adjustments may be in response to user actions and may create a more immerse experience for the user. Such adjustments may be determined from interaction data received from a user device, with may identify a service provider, a product, or an activity that the user is currently engaging in or is interested in. One or more secondary devices may be identified to be within an area around the user device and one or more environmental rules associated with the service provider, product, or activity may be determined and communicated to the one or more secondary devices to cause the one or more secondary devices to adjust a physical environment of the area proximate the user device.

A record control apparatus controls record of a data item in one or more record sections. The record control apparatus includes: a data acquisition section that acquires the data item having multiple types; a data storage section that stores in the record section, the one or more data items matching a record condition prepared in advance among the acquired data item having multiple types; and a condition change section that defines the record condition as an old record condition, and sets so that the data storage section utilizes a new record condition in place of the old record condition when receiving the new record condition different from the old condition from an outside.

A particular implementation correlates a broadcast media item, which has a metadata element containing either a station call sign or channel number for a program, to a specific broadcast frequency and a virtual channel that a service provider broadcasts the program on. A command string is algorithmically defined to encode the frequency and physical channel, and is presented to the tuner hardware for locking onto and decoding the signal. A URL including the command string can then be generated. Consequently, a DLNA client device can engage a media renderer to play the broadcast media item through the exchange of a URL and a control interface.

A video switching system, which can be part of an audio video receivers (AVR), enables simultaneous routing of multiple independent video streams (e.g., 8K video streams) received at HDMI inputs of the AVR from digital media sources to multiple selected digital display devices.

Methods, systems, and apparatuses are described for testing communication with a device. A multimedia receiver may be communicatively coupled to a media device, such as a source media device. The multimedia receiver may transmit a test command to control the source media device using a communication protocol. A video frame output by the source media device may be obtained. Based at least on the video frame, it may be determined whether the source media device received the test command. In response to a determination that the source media device received the test command, an indication may be stored that the source media device may be controlled using the communication protocol.
