摘要： A television system is provided comprising a television set with at least one television tuner, and a broadcast data receiver for selective operation to receive data for the generation of one of a number of selectable television channels. Detection means are provided to detect spectral emissions from the television tuner that are a value from its local oscillator to allow identification of an analogue channel selected for display by the user. The broadcast data receiver is controlled to decode and process digital data relating to the identified analogue channel and display the processed digital data to produce the selected channel via the television system.

摘要： A circuit for discriminating between received signals and a method therefor are provided. The circuit includes a detector for detecting a peak signal based on the degree of correlation between a received signal and a reference signal and a generator for generating a discrimination signal showing that the received signal is a high definition signal if the peak signal is detected in a predetermined period and showing that the received signal is a signal of an analog broadcasting method if the peak signal is not detected in the predetermined period. This can prevent the improper operation of a receiver by automatically determining whether the received signal according to a channel selection is a high definition digital signal or an analog broadcast signal.

摘要： In a channel selection device in the digital/analog broadcasting receiver, when an instruction of the main/sub-channel change is given by ten keys, inputting by null-null key causes the main channel being currently received to be fixed, and a display device to OSD display a state of waiting for the sub-channel. This allows the hierarchical structure of the channel to be understood intuitively, and the input steps of the main channel to be simplified, thereby allowing the channel selection to be efficiently performed.

摘要： A channel selection device used in a digital/analog broadcasting receiver changes a channel according to a channel upward/downward changing instruction by selectively using the following procedures. The first procedure B is used to search for a desired physical channel when there is no channel information; the second procedure A is used to select a channel when there is information of the current physical channel; the third procedure is used when a channel to which the current channel is changed upward/downward exceeds the current physical channel range; and the fourth procedure D is used when information of all the channels is held. Thus, it is possible to appropriately select a channel automatically and also to obtain the channel information automatically when the channel is changed.

摘要： A digital/analog TV common-use receiver having a single ghost canceler, and a ghost cancellation method are provided. The single ghost canceler includes a first filter coefficient generator for generating first filter coefficients using a first reference signal included in the analog TV signal, a second filter coefficient generator for generating second filter coefficients using a second reference signal included in the digital TV signal, and a digital filter for filtering the analog TV signal using the first filter coefficients if the analog TV signal is received, and the digital TV signal using the second filter coefficients if the digital TV signal is received. Since an equalizer used when receiving a terrestrial digital TV broadcast is also used upon receiving a terrestrial analog TV broadcast, the single equalizer can correspond to both digital and analog TV signals.

摘要： The invention comprises a method of selecting for further processing (e.g., display) a desired television channel suitable for use in a television receiver capable of receiving both analog (e.g., NTSC, PAL or SECAM) and digital (e.g., ATSC or DTB) television signals. The method provides appropriate user feedback such that channel selection is effected in a relatively rapid manner utilizing one of a direct channel selection, an electronic program guide selection process, a picture in picture montage selection process or a combination thereof. One embodiment of the invention implements a method for masking the channel selection latency period inherent in ATSC-like television systems.

摘要： A receiver which receives both HDTV and NTSC signals, and a method for selecting received signals, are provided. According to this receiver and method, a broadcasting mode and a channel mode are set by the user. When the broadcasting mode is set to be an NTSC mode, only an NTSC signal is selected to be displayed. When the broadcasting mode is set to be an HDTV mode, only a high-definition (ATV) signal is selected to be displayed. When the judged broadcasting mode is an automatic mode, a judgement is made by the receiver whether an NTSC signal exists in a received signal. If no NTSC signal is present in the received signal, the ATV signal is selected for display. If the NTSC signal exists in the currently-received signal, selection between NTSC and ATV signals is made based on the channel mode set by the user. If the channel mode is set to NTSC, then the NTSC signal is selected for display. If the channel mode is set to HDTV, then the ATV signal is selected for display. Therefore, the HDTV and NTSC signals can both be received, and when both NTSC and HDTV signals exist in a channel, one of them can be selectively received.
摘要翻译：同时提供接收HDTV和NTSC信号的接收机以及接收信号的选择方法。根据该接收方法，用户设定广播模式和频道模式。当广播模式被设置为NTSC模式时，仅选择显示NTSC信号。当广播模式被设置为HDTV模式时，仅选择显示高分辨率（ATV）信号。当所判断的广播模式是自动模式时，由接收机判断接收到的信号中是否存在NTSC信号。如果接收信号中没有NTSC信号，则选择ATV信号进行显示。如果NTSC信号存在于当前接收到的信号中，则基于由用户设置的信道模式进行NTSC和ATV信号之间的选择。如果通道模式设置为NTSC，则选择NTSC信号进行显示。如果频道模式设置为HDTV，则选择ATV信号进行显示。因此，可以接收HDTV和NTSC信号，并且当NTSC和HDTV信号都存在于信道中时，可以选择性地接收其中的一个。

摘要： Radio receivers for receiving DTV signals, in accordance with the Advanced Television System Committee (ATSC) standard, or analog TV, in accordance with the National Television Systems Committee (NTSC) standard, each use a single first detector for both types of signal. This single is followed with an intermediate-frequency amplifier providing amplification both for digital television signal and for the amplitude-modulated NTSC video carrier of an analog television signal. Preferably, the shared intermediate-frequency amplifier is a high-band intermediate-frequency amplifier having fixed gain and having its bandwidth determined using a surface-acoustic-wave filter with flat-amplitude midband response, steep-slope skirts, and linear phase throughout its passband. A second mixer, which downconverts the high-band intermediate-frequency amplifier response to a low-band intermediate-frequency signal, is followed by a respective low-band intermediate-frequency amplifier for digital television signal and a respective low-band intermediate-frequency amplifier for the amplitude-modulated NTSC video carrier of an analog television signal. The respective low-band intermediate-frequency amplifier for digital television signal employs automatic gain control of reverse type and avoids automatic gain control of forward type in order to maintain linearity of gain. The respective low-band intermediate-frequency amplifier for the amplitude-modulated NTSC video carrier employs automatic gain control of forward type in order to keep noise figure lower.
