In preferred embodiments, a system including a transmitter, a receiver, and a serial link, in which the transmitter is configured to transmit video data, embedded-clock auxiliary data (or auxiliary data derived from embedded-clock auxiliary data), and a video clock over the link to the receiver. The transmitter is configured to extract a sample clock from the auxiliary data without use of a phase-locked loop, and to generate time stamp data in response to the sample clock and the video clock. Typically, the auxiliary data are SPDIF (or other) audio data, and the sample clock changes state in response to codes that occur periodically in the audio data. Other aspects of the invention are a transmitter for use in such a system, a time stamp data generation circuit for use in such a transmitter, and a method for generating time stamp data in response to a stream of embedded-clock auxiliary data and a video clock.

Method and circuit for generating time stamp data from an embedded-clock audio data stream and a video clock

In a touch display device, a controller generates a touch sync signal for controlling timing of a touch sensing period and a display period in each of a plurality of frames. A touch panel has a plurality of touch electrodes in a display area to generate touch sensing signals indicating whether or not a touch occurs during the touch sensing period. A touch sensing circuit supplies a touch drive signal to the plurality of touch electrodes during the touch sensing period and detects if the touch occurred based on the touch sensing signals received from the plurality of touch electrodes. A touch assistance line surrounds the display area and is disposed in the non-display area of the touch panel. A touch assistance signal supply circuit generates a touch assistance signal on the touch assistance line. The touch assistance signal mimics the touch drive signal during the touch sensing period.

Embodiments of the invention are generally directed to conversion of multimedia data streams for use by connected devices. An embodiment of a method for processing data includes receiving a data stream in a first multimedia data format at a first device, and inserting a replacement video portion into the received data stream to generate a modified multimedia data stream in a second multimedia data format. The modified data stream is provided to a second device coupled to the first device.
