Provided are a circuit and method for sampling a valid command using a valid address window extended for a high-speed operation in a double pumped address scheme memory device. A method for extending the valid address window includes: inputting a valid command signal and a first address signal at the first cycle of a clock signal; inputting a second address signal at the second cycle of the clock signal; generating a decoded command signal and extended first and second internal address signals respectively in response to the command signal and the address signals; and latching and decoding the extended first and second internal address signals in response to the decoded command signal.
Abstract:
A broadcast service provider must transmit broadcast programs by dynamically reflecting real-time reconfiguration of broadcast timetables and broadcast programs of a plurality of broadcast program providers and the broadcast service provider.A broadcast program providing apparatus and method for supporting dynamic delivery of program timetables and broadcast programs are provided. The apparatus includes a broadcast time organizer generating a third broadcast timetable by organizing broadcast times using a first broadcast timetable obtained by organizing broadcast times of first broadcast programs provided by a plurality of broadcast program providers or both the first broadcast timetable and a second broadcast timetable obtained by organizing broadcast times of second self-produced broadcast programs, and a broadcast program controller transmitting an exact broadcast program at an exact broadcast time according to the third broadcast timetable using the first broadcast programs received from the plurality of broadcast program providers or both the first broadcast programs and the second self-produced broadcast programs, which correspond to the third broadcast timetable. Thus, a broadcast service provider can transmit broadcast programs by dynamically reflecting real-time reconfiguration of broadcast timetables and broadcast programs of a plurality of broadcast program providers and the broadcast service provider.
