Abstract: A system and method for screen mirroring and casting using a near field communication connection to initialize a wireless connection between a client device and a server device. The client device is initially placed in proximity of a near field communication antenna connected to the server device. This proximity triggers the establishing of a near field communication connection, through which setup parameters for a wireless connection are sent, by the server device, to the client device. The wireless connection is then established and used to send video data to the server device, which displays the corresponding video images on a display. The server device may also send user input data to the client device.

Abstract: A method of identifying and scaling a region of interest on a display device is presented. The region of interest is detected based on the rate of change between frames. A size of the display area of the display device and aspect ratio are determined. The detected region of interest is scaled to fit the display area in full screen mode based on the display area and the aspect ratio. The region of interest may be, for example, an active video region. In full screen mode, any static or slow-moving images are hidden.

Further, the method includes counting down a timeout counter when the display screen of the wearable device is on, determining whether the motion information indicates a specific pre-defined gesture when the display screen of the wearable device is off, and performing a power management function corresponding to the specific pre-defined gesture when the motion information indicates the specific pre-defined gesture.

Abstract: Systems and methods are disclosed for dynamically providing deep links based on user activity. In one implementation, a processing device determines that an initial deep link is included in publisher digital content to be provided to a user by a publisher. The initial deep link specifies an item. The processing device determine a subset of vendors, from a group of vendors, that provide vendor digital content that enables the user to purchase the item. The group of vendors has a relationship with a deep link provider. The processing device selects one of the subset of vendors based on a history of activity of the user accessing the vendor digital content of the subset of vendors and provides a user-based deep link for the publisher digital content. The user-based deep link directs the user to the vendor digital content of the selected vendor.

Abstract: A system and/or method that reduces the blanking time between changing from one video channel to another video channel, particularly from a digital video channel. The system provides as much video of the old video channel as possible for display until video from the new channel is acquired. Particularly, video output signal from the old channel which is stored in a video packet buffer is provided until the video packet buffer is underflowed (underflow condition or event). This is accomplished while the system is acquiring the new video channel (i.e. the selector in the case of an analog or different frequency digital video channel, or a PID filter of an MPEG transport stream decoder thereof in the case of a digital video subchannel of the old digital video channel). Blanking of the video output may or may not be accomplished if the new video is acquired before an video packet buffer underflow condition or event, else blanking may occur for only a short period of time. This can save about 400-500 ms.

Abstract: An exemplary method relates to buffering closed captioning data.

Abstract: The invention provides a video recording and playback system comprising a video storing and retrieving device coupled to a video display device so as to provide the video display device with frames of video data for display. The video storing and retrieving device includes at least one memory capable of storing frames of video data, comprising packets according to a format. The format provides a trick mode indicator. A controller is coupled to the memory and controls operations of the memory. A user control device is operable with the controller to allow a user to communicate stop and pause commands to the controller. A processor cooperates with the controller so as to clear the trick mode indicator of at least one retrieved packet in response to the stop command. The processor cooperates with the controller to set the trick mode indicator of at least one retrieved packet in response to the pause command.

The system can include a processor that sets a discontinuity indicator in an adaptation field associated with a video frame. A substitute program clock reference (PCR) value also can be set in the adaptation field. The substitute PCR value can be set to a value approximately equal to a presentation time stamp (PTS) of the video frame with which the adaptation field is associated. The processor also can insert an adaptation field with at least one video frame with which an adaptation field was not already associated. The processor also can remove at least one video frame from the stream of multimedia content. Adaptation fields associated with the removed video frame also can be removed.
