Configuration of a multi-display system is facilitated by use of general television receivers (display devices). Multiple digital interface terminals to which each of multiple display devices configuring a multi-display is connected via a transmission path are provided. A video signal is output to each of the multiple digital interface terminals. Replacement of the video signals output from the signal output unit to the multiple digital interface terminals is controlled to display a correct video corresponding to each screen of the multi-display. For example, the replacement of the video signals is controlled according to a video replacement operation signal sent from any of the multiple display devices via the transmission path.

Examples are disclosed and described to facilitate resolution of Internet Protocol address conflicts. An example method includes periodically broadcasting, by the playback device over the network, a probe message, detecting, by the playback device, a change in status associated with the connection, based on the detection, obtaining, by the playback device, a new Internet Protocol (IP) address; and based on the detection, including, by the playback device in at least one probe message broadcast subsequent to the detection, an indication for other playback devices on the network to obtain a new IP address.

Methods and systems provide synchronized sharing of multimedia between multiple devices. The multiple devices may form an ad-hoc network for sharing of multimedia. In an embodiment, group members may have playlist manipulation privileges such as pausing, rewinding, fast forwarding, or adding tracks to the playlist. A system may stream or distribute content according to the shared playlist. Playback may be synchronized for group members so that everyone is exposed to a same part of the content as the same time.

An apparatus comprises a first processing device, the first processing device comprising a physical hardware controller configured for coupling with a second processing device. The first processing device is configured to identify one or more remote multimedia service instances attached to the second processing device and to initiate, at the first processing device, one or more multimedia emulation modules for the remote multimedia service instances attached to the second processing device, the multimedia emulation modules emulating one or more physical multimedia input devices configured for attachment to the second processing device. The first processing device is also configured to provision the remote multimedia service instances to the second processing device by identifying requests for multimedia input, processing the requested multimedia input utilizing hardware resources of the physical hardware controller, and providing modified multimedia input to the second processing device via the emulated physical multimedia input devices.

A system and method are provided for an AV device for use with a video player, one or more speakers, and encoded AV data. The encoded AV data includes multiplexed encoded video data and encoded audio data. The AV device is connected to the speakers via wireless channels. The AV device is able to determine channel delays associated with each wireless channel; synchronize program clocks of the video player and speakers; determine and modify buffer levels of each speaker; demultiplex the encoded AV data to obtain encode video data and encoded audio data; and provide prefetched portions of encoded audio data based on buffer levels.

A method of acquiring access rights to conditional access content. The method comprises receiving an access right on a first terminal through a first communication channel; storing said access right in said first terminal; sending a request for said conditional access content to a content provider, said request containing at least an identifier of an account to which said first terminal is associated, an identifier of the requested content and a piece of information concerning said access right; verifying, by said content provider, the authenticity of said access right using said piece of information concerning the access right; and when there has been a successful verification, marking said access right as used, and sending said conditional access content to at least one terminal linked to said account. The first terminal using near field communication technology (NFC) during at least one transfer of said access rights.

A display apparatus includes: a display; an input interface; and a processor in connection with the display and the input interface and configured to: upon detecting access of a first power amplifier device, output a high-level Hotplug signal at a Hotplug port of the display apparatus; monitor whether a common-mode data packet from the first power amplifier device is received within a first preset duration; in response to the common-mode data packet being received within the first preset duration, send a heartbeat packet to the first power amplifier device, and monitor whether a heartbeat response is received within a second preset duration; in response to the heartbeat response being received within the second preset duration, determine that the first power amplifier device supports e-ARC function; and in response to the heartbeat response being not received within the second preset duration, determine that the first power amplifier device supports ARC function.

An electronic device that obtains a set of remote-control commands is described. During operation, the electronic device may receive an image associated with a second electronic device, where a brand and a model of the second electronic device are initially unknown to the electronic device. Then, the electronic device may perform image analysis on the image to determine at least the brand of the second electronic device. Moreover, the electronic device may access, based at least in part on the determined brand, the set of remote-control commands that are associated with the second electronic device. Next, the electronic device may store the set of remote-control commands in memory. Subsequently, when the electronic device receives user-interface activity information associated with a portable electronic device that specifies selection of the second electronic device, the electronic device may provide the set of remote-control commands to the second electronic device.
