Methods and apparatus for distributing multimedia files units are disclosed. In an exemplary method, a plurality of multimedia files are downloaded using a transportation provider wireless device associated with a fare-based transport vehicle, such as a taxi, bus, ferry, or airplane. The downloaded multimedia files are stored in a data storage unit operatively connected to the transportation provider wireless device. In response to passenger input data received from a passenger wireless device, a desired multimedia file selected by the passenger is transferred to the passenger wireless device or played back using local speakers and/or video displays. In some embodiments, a selected multimedia file is associated with digital rights management information regulating authorized uses of the file.

Various embodiments for social networking influenced map generation are disclosed. One embodiment is a method for generating a map that comprises retrieving, by a computing device, location data from a mobile computing device. The method further comprises determining, by the computing device, at least one attribute corresponding to the mobile computing device according to the retrieved location data and retrieving, by the computing device, information relating to a messaging event occurring on the mobile computing device. The method further comprises generating, by the computing device, a map displaying a path of traversal of the mobile computing device based on the retrieved location data, the map further comprising at least one graphical representation relating to the messaging event, the at least one graphical representation being displayed on the path of traversal.

A method to indicate delays in a push-to-talk over cellular (PoC) group call may include offsetting a timestamp in a data stream being transmitted to a late listener to indicate a delay from when the data stream was transmitted to a first listener. The data stream includes data convertible to speech. The method may also include transmitting the data stream including the offset timestamp to the late listener.

A method of enhancing audio quality for Internet protocol (IP) based systems using an adaptive multi-rate (AMR) payload format is presented. If a network buffer indicative of network congestion exceeds its threshold a determination is made whether to place a NO DATA frame into the current RTP packet instead of the AMR frame. If network conditions are too congested then a NO DATA frame is placed into the current RTP packet. The process is repeated for each incoming AMR frame. The process first ensures that the AMR coding rate is set to its lowest possible coding rate prior to substituting a AMR frame with a NO DATA frame. The substitution pattern is spread over the entire RTP packet to avoid clusters of NO DATA frames. The process can also single out AMR frames of lower energy value that would be good candidates for substitution.
