Abstract: A method consistent with certain embodiments, of processing a received encrypted frame signal, wherein the received encrypted frame signal is indicative that a specific video frame is encrypted, involves receiving a video signal including the received encrypted frame signal; wherein the received video signal comprises a received bit stream; synthesizing the received encrypted frame signal to produce a synthesized encrypted frame signal that is in synchronization with the received encrypted frame signal; determining if a sink wireless receiver is locked to the received bit stream, and if so, passing the received encrypted frame signal to the sink device; and if the sink wireless receiver is not locked to the received bit stream, passing the synthesized encrypted frame signal to the sink device. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.

Abstract: Data encoded with a video clock is transmitted over a communication link in accordance with a communication reference signal, which in one embodiment is a wireless link. In one embodiment, the video clock is independent from the communication reference signal. The communication reference clock, which may be known to both the transmitter and receiver, is used to determine a frame period. On the receiver-side, the number of video cycles of the video data which are actually received are counted. The video clock may then be regenerated using the determined frame period and counted video clock cycles.

Abstract: A method and system using a single interleaver at a either a receiving device or a transmitting device where a first symbol set is read from the single interleaver and concurrently with a second symbol set is written to the single interleaver, and a controller that synchronizes the reading of the first symbol set from the interleaver and the writing of the second symbol set to the interleaver so that a particular symbol of the second symbol set is only written to a location of the interleaver after a particular symbol of the first symbol set has been read from the location. The controller may switch between orders, e.g., row order and column order, of reading and/or writing symbols to the single interleaver when all of the symbols for a particular set of symbols associated with the single interleaver have been read, according to another embodiment.

Abstract: In one embodiment, a method comprises monitoring geographical locations of a device equipped with a global positioning satellite (GPS) receiver, which is moved over a travel route. During movement or subsequently thereafter, information pertaining to the geographical locations is uploaded to a processing center to compute travel patterns for the commuter in possession of the device. As a result, prior to the normal point of time when the computer travels over the travel route, travel-related information for the travel route is downloaded to the device for use in selecting a route of travel.

Abstract: A system and method for automatically performing a channel selection procedure in a wireless network includes a forward transmitter that embeds an identifier into forward data that is transmitted over a forward link. A forward receiver then receives the forward data on the forward link, and removes the identifier from the forward data. A reverse transmitter receives the identifier from the forward receiver, and embeds the identifier into reverse data that is transmitted over a reverse link on a selected reverse channel chosen from among a plurality of available reverse channels. A reverse receiver then searches the reverse channels to identify the selected reverse channel containing reverse data with the identifier embedded. The reverse receiver may then utilize the identified reverse channel for effectively receiving the reverse data.

Abstract: A value representing a clock, such as a video clock, that is independent of the clock of a communication system, is encoded using the communication system clock and then sent with the video for subsequent recovery by a receiver. In particular, during an interval defined by the communication system clock, the number of video clock cycles is counted and sent to the receiver. The receiver recovers the video clock using the number of video clock cycles and the communication system clock.
