An apparatus for synchronizing the initiation of the playback of packetized multimedia data received asynchronously in each receiver in a system, and for synchronizing the real time playback in a plurality of receivers in the system, from the transmitter over a wired communications medium. The clocks in the transmitter encoder and the receiver decoders operate asynchronously but at substantially the same rate. Initiation of playback is synchronized according to the arrival time of a first received data packet having a zero-valued retransmit number. Real time playback among a plurality of receivers is synchronized according to a measured time difference between an operating rate of the encoder and an operating rate of the decoder.

Apparatus for synchronization of digital multimedia data communicated over wired media

A method and apparatus is provided for synchronizing both the initiation of playback of digital multimedia data in one or more receivers and the rate of playback of the digital multimedia data in the one or more receivers, all receiving the digital multimedia data from a single transmitter, without transmitting clock or timing signals to the receiver(s). An exemplary embodiment is described using the AC powerline as a medium of transmission, although the method and apparatus are adaptable to a variety of communication media.

Apparatus, and an associated method, for facilitating personalization of a weather band radio that receives SAME messages broadcast by the NWR system. Alphanumeric indicators of locations are displayed upon a user display element. And, a listener of the radio enters, by way of a user input actuator, selection of selected geographical areas, identified by the alphanumeric indicators. The selected alphanumeric location is used to form a six-digit location code defined by the Federal Information Processing Standards (FIPS). And, the code so-formed is used by the weather band radio, selectably to alert weather anomalies broadcast by the NWR system within the selected geographical area of interest.

Provided is a transmitter that includes a channel selector for modifying an operating frequency of a radio-controlled toy. The transmitter has a channel selection switch that enables a user to pick a channel from a set of predefined channels. The selected channel is then transferred to the toy. For example, a microcontroller unit within the transmitter may be used to detect the selected channel. The toy is placed in contact with the transmitter and the transmitter's microcontroller unit communicates the channel to a microcontroller unit inside the toy. The toy's microcontroller stores the channel in a memory in the toy. The toy then tunes to the stored frequency to receive control signals from the transmitter.
