| 20080278634 | SYSTEMS AND METHODS FOR CHANNEL SCANNING - Methods for channel scanning are provided. An embodiment of a method for channel scanning comprises scan progress information stored when interrupting a channel scanning process. A carrier RF subsequent to the most recently processed carrier RF is locked onto with reference to the stored scan progress information when resuming the interrupted channel scanning process. Channel information of a program carried by the locked carrier RF is acquired. The acquired channel information of the program is stored in a channel table. | 11-13-2008 |
| 20090040384 | VIDEO APPARATUS CAPABLE OF OUTPUTTING OSD DATA THROUGH UNAUTHORIZED OUTPUT PATH TO PROVIDE USER WITH WARNING MESSAGE OR INTERACTIVE HELP DIALOGUE - A video apparatus includes a video processor for performing video processing to generate normal video data. The video processor includes an on-screen display (OSD) module for selectively generating OSD data that is capable of being mixed into the normal video data. The video apparatus further includes a digital output path including a digital transmitter and an analog output path including a digital-to-analog converter (DAC). The video apparatus is capable of outputting OSD data through an unauthorized output path out of the digital and analog output paths to provide a user with a warning message or an interactive help dialogue. | 02-12-2009 |
| 20090187874 | CIRCUIT AND CIRCUIT DESIGN METHOD - A circuit and a circuit design method are provided. The circuit operates between a first power source voltage and a ground voltage. The circuit comprises at least one low speed circuit path and at least one high speed circuit path. The low speed circuit path adjusts voltage level at the first power source voltage or the ground voltage. The low speed circuit path provides a first return path and isolates unwanted noise signals for a signal on the high speed circuit path. | 07-23-2009 |
| 20090231175 | MULTIMEDIA SIGNAL PROCESSING APPARATUS - A multimedia signal processing apparatus includes: a first digital-to-analog converter (DAC) for performing digital-to-analog conversion on a first set of digital values to generate a first set of analog signals, where the first set of digital values represents a first portion of an image to be displayed; a second DAC for performing digital-to-analog conversion on a second set of digital values to generate a second set of analog signals, where the second set of digital values represents a second portion of the image to be displayed; and a plurality of driver integrated circuits (ICs), coupled to the first and the second DACs, for driving according to the first and the second sets of analog signals, respectively. | 09-17-2009 |
| 20090317057 | APPARATUS AND METHOD FOR SELECTIVELY OUTPUTTING HD/SD SIGNALS AS HIGH DEFINITION VIDEO ACCORDING TO COPY PROTECTION - An apparatus for outputting standard definition (SD) and high-definition (HD) analog signals as high-definition (HD) video according to copy protection is disclosed. The apparatus includes: a determination block, for receiving a specific signal and determining whether the received specific signal has copy protection; and a scaling block, coupled to the determination block, for selectively scaling the received specific signal according to at least a copy protection determination result generated by the determination block. | 12-24-2009 |
| 20090317059 | APPARATUS AND METHOD OF TRANSMITTING / RECEIVING MULTIMEDIA PLAYBACK ENHANCEMENT INFORMATION, VBI DATA, OR AUXILIARY DATA THROUGH DIGITAL TRANSMISSION MEANS SPECIFIED FOR MULTIMEDIA DATA TRANSMISSION - A data transmission interface apparatus is provided for communicating with another data transmission interface apparatus through a digital transmission means specified for multimedia data transmission. The data transmission interface apparatus has at least a processor for processing multimedia data; and a data converting circuit, coupled to the processor, for converting a plurality of first multimedia data sets into a plurality of second multimedia data sets; and for converting a plurality of first auxiliary data sets into a plurality of second auxiliary data sets. | 12-24-2009 |
| 20100130159 | METHOD OF SENDING AND RECEIVING CALL WITH SPECIFIC REQUEST - A specific code indicative of a specific request is used to provide a communication device with an ability to send specific calls, such as emergency calls and silent calls, and the ability to distinguish the specific calls from the received calls. A method of sending a call includes generating a specific code indicative of a specific request, adding the specific code to a call, and then sending the call to a receiver for notifying the receiver of the specific request. A method of receiving a call includes determining whether a received call comprises a specific code indicative of a specific request, and generating an indication in response to the specific request when the received call is determined to comprise the specific code. | 05-27-2010 |
