In a system comprising a content performance device, multiple status display devices can communicate with the performance device to receive messages updating status of content being performed by the performance device, or being transmitted to one or more other performance devices. Content performance devices can include computers configured with software for managing media libraries, for obtaining Internet-based media, as well as more purpose-specific devices, such as digital video recorders, settop boxes, Apple TV, TiVo, and so on. Status display devices, remote controls or client devices can make standing requests to receive status updates as status changes. Status display devices also can function as remote controls for the performance device, and can submit control requests to it, which when effected, are acknowledged to all status display devices, which responsively update their displays. Each status display device can interpret content sent for communicating status updates, and can make changes to a respective display, or to other features or functions according to its programming. Status display devices can include personal information managers, smart phones, laptops, palm tops and other electronic devices capable of displaying playback status information received from the content performance device. |
