Abstract: An automatic feedback adjustment device for a digital antenna includes a digital antenna unit, a trafficator, a tuner, a demodulator, an antenna direction driver unit, a secondary controller, and a primary controller. The digital antenna unit is a digital video/broadcasting antenna system. The trafficator is connected to the digital antenna unit to retrieve direction data associated with the actual elevation angle and direction. The tuner is connected to the digital antenna unit and the demodulator is connected to the tuner in order to receive and convert a transmission signal from a transmission terminal into the video data and a received-signal quality signal. The antenna direction driver unit is connected to the digital antenna unit in order to drive adjustment of direction and elevation angle of the antenna.

Abstract: A method for filtering the SDTV channels in a DVB is provided, including the following steps: using the video frequency ID and center frequency of the SDTV channel of the user's choice to look up a table to obtain at least a remaining video frequency ID different from the video frequency ID of the SDTV channel, while the remaining video frequency ID having the same center frequency as the SDTV channel; configuring a plurality of registers in the controller; and the controller discarding a plurality of DVB packets according to the registers. The controller can be either a PCI_EXPRESS controller or a USB controller.

Abstract: Disclosed is a storage apparatus for digital TV video/analog TV video/digital audio broadcasting/analog audio broadcasting media (DTV/ATV/DAB/AAB). The storage apparatus comprises a controller, a DTV/ATV/DAB/AAB interface converter and at least one storage media interfaces. The controller has a plurality of terminals for controlling the storage apparatus. The DTV/ATV/DAB/AAB interface converter connects to one of the terminals and a digital/analog tuner to receive DTV/ATV/DAB/AAB signals and converts the DTV/ATV/DAB/AAB signals into DTV/ATV/DAB/AAB data. The storage media interfaces respectively connect to the terminals of the controller and to at least one portable storage media, for storing the DTV/ATV/DAB/AAB data received from the DTV/ATV/DAB/AAB interface converter into the portable storage media. The controller can be an OTG controller.

Abstract: An audio data storage and playback apparatus is provided, including at least a USB hub or USB SIE, at least a storage media interface, and an audio codec. An upstream port of the USB hub or the USB SIE is connected to an electronic device with a USB interface. The storage media interface is connected to a downstream port of the USB hub or an endpoint of a USB SIE. The storage media interface can be connected to a portable storage media, such as flash memory, CD-R/W, DVD-R/W, and hard disk drive, to enable bi-directional data transmission and storage between the electronic device with a USB interface and the portable storage media connected to the storage media interface. The audio codec player forms a bi-directional data transmission connection with the storage media interface. The audio codec player is connected to at least an audio player and an audio input device.

Abstract: A controller for filtering sub-channels of DVB is provided, including a media access control (MAC) unit, at least a data compression unit and at least a physical interface circuit. The MAC unit includes a plurality of registers. The MAC unit is connected to the DVB packets through a bus, and the registers provide storage for the program identification of at least one DVB sub-channel packet so that the MAC unit can determine whether to discard or output the DVB packet based on the program identification. The data compression unit is connected to MAC unit for being controlled to determine whether the packet should be compressed before output. The physical interface circuit is connected to the MAC unit and the data compression unit for outputting the compressed or uncompressed packets.
