摘要:
Video distribution methods include providing a primary video data stream having a first image size and formatted in a first video display format. A transmission data stream is formed having a plurality of blocks of data including at least first and second data fields. The first data field includes a secondary video data stream extracted from the primary video data stream and is formatted for display in a second video format. The second data field includes supplemental data extracted from the primary video data stream and configured to provide, when combined with the data of the first data field, a tertiary video data stream formatted for display in a third video format. The transmission data stream is multicasted from a wireless communication transmitter to a plurality of wireless communication terminals. Wireless communication terminals and systems are also disclosed.

Disclosed is a method of requesting content from a mobile broadcast service provider wherein the mobile broadcast service provider maintains a variety of content offerings that can be broadcast to a portable mobile communications device. One method comprises creating a subscription profile on the portable mobile communications device that includes requested content from the content offered by the mobile broadcast service provider. The subscription profile is sent to the mobile broadcast service provider so that the mobile broadcast service provider can aggregate the requested content onto a plurality of time multiplexed channels. The plurality of time multiplexed channels are then broadcast to the portable mobile communications device. The portable mobile communications device then de-multiplexes the time multiplexed channels of requested content to display the requested content.

Embodiments of the invention are directed to a method of keeping track of and staying tuned to a transmitter even when a receiver is moving at a relatively high speed. Electronic equipment carried on fast moving vehicles and comprising receiving means can experience a shift in the frequencies received due to Doppler shift. Embodiments provide a way of taking such a Doppler shift into account by means of acceleration measurements of the electronic equipment. Some embodiments may be used in electronic equipment containing a GPS receiver or the like, where re-tracking of satellites can be power and time consuming.
摘要:
The position of a given mobile terminal is determined by communicating satellite positioning system information between the given mobile terminal and at least one other mobile terminal over a short-range, ad hoc wireless network, such as a Bluetooth network, to cooperatively determine the position of the given mobile terminal by the given mobile terminal and the at least one other mobile terminal that communicate over the short-range, ad hoc wireless network. Satellite positioning system information may communicated by distributing processing of the satellite positioning information, by distributing receiving of satellite positioning system information from a satellite, by communicating assistance data and/or by synchronizing timing of satellite positioning information, between the given mobile terminal and the at least one other mobile terminal over the short-range, ad hoc wireless network.
摘要:
An accessory for an electronic device includes a cable, such as an audio cable having first and second ends, and a plurality of light guides attached to the cable. The light guides have first ends proximate the first end of the cable and extend along a length of the cable. Respective ones of the plurality of light guides terminate at different points along the length of the cable. The accessory may further include an interface adapter coupled to the cable and the plurality of light guides and at least one light emitting device, and the light guides may be configured to receive light emitted by the at least one light emitting device.
摘要:
Methods of establishing a point-to-point communication connection using an uplink radio resource of a communication system include allocating an unused portion of the uplink radio resource of the communication system as a communication channel. The communication channel is assigned to establish the point-to-point communication connection.
摘要:
A target modulation is detected in a signal, e.g., a radio signal received by a device such as a mobile communications terminal. Respective target modulation correlations for respective carrier timing hypotheses are determined by demodulating signal values corresponding to the signal for the respective carrier timing hypotheses using a common carrier demodulation template and detecting the target modulation from the target modulation correlations. The target modulation may be, for example, a pseudonoise (PN) code, such as a GPS code or a CDMA communications system code, and the carrier timing hypotheses may correspond to various potential Doppler shifts.
摘要:
Portable electronic devices are provided including a housing and a display integrated with the housing. A thumb-operable input device is positioned on a side of the housing. An indicator is provided on the display and is operatively associated with the thumb-operable input device. The indicator is positioned on the display to highlight and/or select menu items on the display responsive to input received at the thumb-operable input device. Related man-machine interfaces (MMIs) are also provided.
