A system is provided for use with a video input signal and a video unit. The video input signal can be one of a two dimensional video signal and a three dimensional video signal. The video unit can display a three dimensional video and a two dimensional video. The system includes a receiver portion, a processing portion, a switching portion and an output portion. The receiver portion can receive the video input signal. The processing portion can output a first signal in a first mode of operation and can output a second signal in a second mode of operation, wherein the first signal is based on the video input signal and the second signal is based on the video input signal. The switching portion can switch the processing portion from the first mode of operation to the second mode of operation. The output portion can provide an output signal to the video unit, wherein the output signal is based on the first signal when the processing portion operates in the first mode of operation and wherein the output signal is based on the second signal when the processing portion operates in the second mode of operation. The first signal includes a two dimensional video signal, whereas the second signal includes a three dimensional video signal.

Dual mode user interface system and method for 3D video

A method of processing a sequence of coded video frames conveyed by a digital data stream, where each frame represents an image, includes receiving the sequence of coded video frames at a recording device, determining a frame interval between presentation of an ith coded frame of the sequence and an (i+1)th coded frame of the sequence, calculating a stream time stamp for the ith coded frame, and calculating a stream time stamp for the (i+1)th coded video frame based on the stream time stamp for the ith coded video frame and the previously determined frame interval.

Method of processing a sequence of coded video frames

A client device, which can be a set-top box or a gateway device, can be operative to continue processing content (e.g., a television program) in its pipeline, while it is requesting a different content (e.g., tuning or obtaining a targeted ad). Instead of seeing a blank screen or a muted still-shot, the user in some circumstances would be able to continue to see a segment of the processed content information.

Tuning Behavior Enhancement

A method and system that configures an HDMI source device to use initial output parameters for communicating with an HDMI sink device, detects an abnormal operation performed by the HDMI sink device, selects a test of the HDMI sink device, applies the test, evaluates a result to determine whether the test produces a desired result, and modifies the initial output parameters to create revised output parameters. When the test produces the desired result, the revised output parameters will enable the HDMI sink device to produce the desired result. When the test fails to produce the desired result, the revised output parameters are conservative parameters that fail to produce the abnormal operation. The method reconfigures the HDMI source device to use the revised output parameters for communicating with the HDMI sink device, and saves the revised output parameters.

HDMI source/sink interoperable configuration determination process

A method of modifying a digital data stream composed of a sequence of frames, where each frame represents an image and includes a data field specifying a presentation time stamp value for the frame. If there is a discontinuity in presentation time stamp value between a next frame and a first frame, a value representing a stream time stamp of interest is assigned to a variable for representing the value of the stream time stamp of interest at a point of discontinuity in presentation time stamp, and a value of the presentation time stamp is assigned to a variable for representing the first frame's clock time based on presentation time stamp, and the next frame is stored in a database using as an index the value representing a stream time stamp of interest.
