Abstract: A user may input one or more messages (e.g., visual or audio content) with respect to a projection device that is to project the messages to users within an environment. The user may additionally input related information that dictates a context and manner in which the messages are to be projected. The projection device may monitor the environment to identify users, events or actions within the environment. Upon detecting and identifying a particular user, the projection device may visually project the messages onto a surface within the environment, or may audibly output the messages within the environment, which may convey a particular meaning to that user. Optionally, the projection device may authenticate the user in order to determine that the user is the intended recipient of the messages.

Abstract: A broadcast radio architecture includes an internet-enabled radio and a remote audio services system. The internet-enabled radio receives broadcast audio content and plays through a speaker, the audio content that is received. The internet-enabled radio receives a user command to replay, from the beginning, a song that is currently being played. In response to the user command, the internet-enabled radio transmits over a network to the audio services system, a snippet of the song that is currently being played. Using the snippet of the song, the audio services system identifies a song from which the snippet was likely recorded and transmits a data stream that includes the song, in its entirety, back to the internet-enabled radio. To provide additional value, the audio services system may also identify and transmit to the internet-enabled radio, additional content that is deemed likely of interest to users interested in the identified song.
