Abstract: A method of controlling timing for a touch and display driver system includes the steps of: receiving an external signal; generating a plurality of time units each having a display period and a touch period; generating an internal signal for controlling a display operation in the display period; and synchronizing the internal signal with the external signal for a time unit among the plurality of time units at a time point different from at least one of the start of the time unit and the end of the time unit.

Abstract: A method of power signal detection of set top boxes under test is disclosed. According to certain embodiments, detection of a failure mode of a set top box (STB) under test is based on video signal detection where the video signal is associated with multiple video output types and AC power outlet signal detection.

Abstract: An I/O interface supports scrambling, where the scrambling can include nonlinear scrambling of the scrambling code, or dynamic bus inversion of the scrambling code, or selective switching of selected bits of the scrambling code, or a combination of these. The transmitting device includes a scrambler and the receiving device includes a descrambler. Both the scrambler and the descrambler generate a linear feedback scrambling code modified by applying one or more of the techniques mentioned above. The modified scrambling code may cause fewer than half of the scrambled output bits to be toggled with respect to a previous scrambled output. The scrambler applies the modified scrambling code to a signal to transmit. The descrambler applies the modified scrambling code to a received signal.

Abstract: A network device receives a unique device identifier (UDID) associated with a mobile device belonging to a user, and content channel subscription information associated with the user, and stores the UDID and the content channel subscription information in a database. The network device receives the UDID and a channel identifier (ID) from a content application executing at the mobile device, and accesses the database with the UDID and the channel ID to verify the user's subscription to a content channel identified by the channel ID. The network device sends, if the user's subscription to the content channel is verified, a channel permission and a timestamp, to the mobile device, such that the mobile device is able to access content at a content provider corresponding to the channel ID prior to an expiration time that is based on the timestamp.
