摘要： Provided are a tuning method according to a variable key input length and a broadcast receiving apparatus using the tuning method. The tuning method includes: if it is determined that an input length of one of at least one or more key inputs is more than or equal to a predetermined time, tuning to a first type broadcast; and if it is determined that the input length is less than the predetermined time, tuning to a second type broadcast different from the first type broadcast. Thus, different types of broadcasts can be tuned according to a length of a key input performed by a user. As a result, a digital broadcast channel can be directly input using only a number key.

摘要： A passive entry and immobilizer key for vehicles comprises an integrated front-end circuit (12b) with three battery- supplied receiver channels (14, 16, 18) , each connected to an associated external antenna circuit with an inductor-capacitor combination (LR, CR) having a resonant frequency in the very low frequency range. The three antennas are arranged in a three- dimensional configuration. An immobilizer transponder (22) is supplied by energy received from an external transponder antenna circuit and stored in a storage capacitor (CL) . The transponder antenna circuit includes an inductor-capacitor combination (LR, CR, CL) having a resonant frequency in the low frequency range. The transponder antenna circuit shares at least one inductive component (LR) with the antenna circuit of one of the three receiver channels. A capacitor in the transponder antenna circuit is selectively disconnected to change the resonant frequency from a frequency in the very low frequency range to a frequency in the low frequency range. Accordingly, one of the three antenna circuits has a dual function. A first function is that in a three-dimensional analog front end of a passive entry system that operates in the very low frequency range. A second function is that in a transponder of an immobilizer system that operates in the much higher low frequency range. As a result, only three antenna coils need to be implemented in the key.
