Abstract: Protected content from a media source is transmitted via a wireless link using modified wireless encryption keys. Content to be delivered under a content protection scheme, e.g. High-bandwidth Digital Content Protection (HDCP), from a media source to a media sink is received at a wireless communication device. A content protection key, or a digital rights management (DRM) key, associated with the media sink is used to generate DRM modified wireless encryption keys. These modified wireless encryption keys are used to encrypt the wireless transmission using wireless encryption techniques, such an advanced encryption standard (AES) protocol, and transmit the encrypted content over a wireless link. The DRM modified keys can be used, for example to seed a Wi-Fi Protected Access (WPA) encryption engine in place of other keys normally used in the wireless encryption process, thereby effectively integrating the DRM content protection scheme with standard wireless encryption and transmission.

Abstract: A content distribution system may distribute content to a plurality of receivers on demand. When it is determined that two different receivers are receiving the same program but one receiver requested the information prior to the other, bandwidth may be conserved by increasing the rate of data flow to one user and decreasing the rate of data flow to another user, in one embodiment, until such time as both users are receiving the same portion of the program at the same time. In such case, the program may be simultaneously distributed to two users on the same channel, conserving bandwidth.

Abstract: A call routing function may receive information from a user profile about how to handle a telephone call. In addition, the call routing function may also receive information about what the user is currently involved in doing. This information may be derived from the user's software-based calendar. Using both sources of information, a call may automatically be appropriately routed by the call routing function.

Abstract: A network including a client and server may send capability determining software from the server to the client. At the client, the software determines the capability of each particular client, forms a message, and sends that message back to the server. Based on the message received as a result of the operation of the software, the server can better provide its services to the client in some embodiments.

Abstract: A cellular telephone using a pair of processors may include a bypass device. The bypass device may be active when a first processor is not responding. In such case, inputs from a keypad or outputs to the display may bypass the first processor allowing continued communication between input/output devices and the second processor. In some embodiments, the first processor may be an applications processor and the second processor may be a baseband processor.

Abstract: A way of configuring a portable device is provided. A portable device comprises a storage unit and a control unit that is communicatively coupled to the storage unit. The control unit is provided to determine whether configuration of the portable device is desired, request configuration information in response to determining that configuration is desired, and receive the requested configuration information.

Abstract: A mobile radio (10) with a synchronization apparatus (14) executes a method (60) for time synchronizing the radio (10) and a base station (12). Base station (12) and radio (10) have internal timers (26, 16). A control unit (18) in the radio (10) receives a signal (29) from the base station (12) and determines the difference F between timers (26, 16, 30) in the base (12) and mobile (10). The control unit (18) writes instructions I(i) and their execution times T(i) to a memory (42) within the radio (10). One of these instructions I(N) reloads the radio timing counter (30) with a corrected value C=f(F,B) at a predetermined time T(N)=B which avoids conflicts with other operations of the radio (10).

Abstract: A radio (10) executes a method (100) for entering and exiting a halt status. Radio (10) has a control unit (18) and an internal timing unit (16). The timing unit (16) has execution logic (32), a status register (46) a counter (30) and a clock source (37). The control unit (18) writes instructions I(i) and their execution times T(i) to a memory (42) within the execution logic (32). One of these instructions is a ‘SWITCH CLOCK’ instruction causing the timing unit (16) to switch between clock signals. One of the instructions is ‘HALT COUNTER’ causing the radio (10) to enter a halt state. The radio (10) can be synchronized to the end of a first communication frame received by it after exiting a halt state.

Abstract: A communications system includes multiple processors (14, 16) and a protocol timer (18). The protocol timer (18) controls the timing of events in the communications system and operates autonomously after it is loaded with initial instructions by one of the multiple processors (14, 16). The protocol timer (18) utilizes a frame event table (50) and a macro event table (46, 48) to trigger events and to generate interrupts of the multiple processors (14, 16). By allowing the protocol timer (18) to operate autonomously, the processors (14, 16) are relieved of timing control, and can be powered down when not in use, thus reducing power consumption of the communications system. Also, by using the protocol timer (18) to control the timing of events, software related errors and interrupt latencies are reduced.

Abstract: A high bandwidth cellular data (HBCD) terminal (500) uses multiple transceivers (528, 534, 5450) and modems (520, 532, 538) to simultaneously establish multiple data links to an HBCD server (114) via a mobile central office (MCO 102). Data links are created on the voice bands of cellular channels associated with one or more secondary mobile identification numbers (MINs) assigned to that terminal as more bandwidth is required. A high bandwidth analog cellular communication protocol simultaneously uses the multiple data links to transmit data. The plurality of secondary MINs and simultaneous links allows increased bandwidth with minimal costs associated to the MCO.
