  • Patent number: 7903087
    Abstract: Method an arrangement for facilitating the use of a trackball on a wireless handheld communication device as a navigation tool and a selection tool of designated information presented on a display screen of the device. A wireless handheld communication device is provided that has at a front face thereof a display screen located above a keyboard suitable for accommodating textual input. A depressible trackball functions as a navigation tool for moving a cursor about on the display screen when rolled and as a selection tool when sufficiently depressed. Cursor movement is affected by digitally engaging the trackball and maintaining the trackball in a navigation zone depth within the device. Selection of designated information is affected by depressing the trackball a predefined amount. The wireless handheld communication device is configured so that no cursor movement is affected by rolling movement of the trackball when in the selection zone.

  • Patent number: 7552142
    Abstract: Method an arrangement for affecting diagonal movement of a cursor 171 on the display screen 322 of a handheld communication device 300 having a reduced alphabetic keyboard. The method includes sensing movement at an auxiliary user input 328 of the handheld communication device 300 indicative of the user's desire to affect diagonal movement of the cursor 171 on the display screen 322 of the handheld communication device 300. X-direction signals and Y-direction signals are produced based on the sensed movement at the auxiliary user input 328. During that time while the necessary signals are being collected and processed, the cursor 171 is held steady on the display screen 322 until a predetermined criterion is met for discriminating whether the user has indicated x-direction cursor movement, y-direction cursor movement or diagonal cursor movement.

  • Publication number: 20090135918
    Abstract: A processor and method are provided for decoding a multimedia file having video and audio data streams that are configured to be played in synchronization. Frames of the video stream are decoded and played with the audio and, to compensate for saturation of the processor usage, two procedures are performed. The first procedure operates at a first periodic interval and slows down the frame rate to reduce processor usage if needed. The second procedure first attempts to speed up the video to catch up to the audio if they are out of sync and if this cannot be done in the next time interval, the decoding of a select number of frames is skipped such that the video and audio data streams are resynchronized.

  • Publication number: 20090052555
    Abstract: A system and method are provided that can be used for applying a deblocking filter to a video according to processor usage, in particular on a mobile device. To determine which of a plurality of deblocking filters to use, the system determines an environment indicator indicative of current processor usage, compares the environment indicator to a primary threshold, wherein the primary threshold is indicative of a maximum acceptable processor usage. If the primary threshold is met, the system foregoes any deblocking filtering. If however the primary threshold is not met, the environment indicator is compared to one or more secondary thresholds and a respective one of the plurality of deblocking filters is applied to the video according to which one of the secondary thresholds is met. Each of the plurality of deblocking filters has a different complexity and thus can be chosen to suit the current system environment.
