In one embodiment, the input is provided from an optical data distribution network.
在本發明之另一態樣中，提供一種用於在複數個預定頻帶中所輸送之資料信號的接收及處理之方法，其特徵在於該方法包括下列步驟：產生一信號，以識別從該等預定頻帶所選擇之要據以擷取資料的需要頻帶；使用同相及正交資料饋送，傳遞來自該需要頻帶之資料信號至一包括第一混波裝置之發射器，以處理該等資料信號，進而建立該需要頻帶之一預定表示；以及從該兩條資料路徑傳遞該資料至一第二混波裝置，以轉換該需要頻帶成需求頻帶，以便被連接至一輸出的至少一個廣播資料接收器及/或一個以上選台器接收及提供該發射器做為一積體電路之一部分。 In another aspect of the invention, a method for receiving and processing a data signal transmitted in a plurality of predetermined frequency bands is provided, the method comprising the steps of: generating a signal to identify from the The predetermined frequency band is selected to capture the required frequency band of the data; the in-phase and quadrature data feed is used to transmit the data signal from the desired frequency band to a transmitter including the first mixing device to process the data signal, And establishing a predetermined representation of the required frequency band; and transmitting the data from the two data paths to a second mixing device to convert the required frequency band into a required frequency band to be connected to an output of at least one broadcast data receiver And/or more than one of the selectors receive and provide the transmitter as part of an integrated circuit.
在一實施例中，當選擇一需要頻帶及該需要頻帶為一不同於該設備在那個時間所處理之頻帶的頻帶 時，改變信號，以識別該需要頻帶及促使該需要頻帶被傳遞至該發射器及轉而至該輸出。 In an embodiment, when selecting a desired frequency band and the required frequency band is a frequency band different from the frequency band processed by the device at that time The signal is changed to identify the desired frequency band and cause the desired frequency band to be passed to the transmitter and to the output.
在一實施例中，提供複數個頻帶至一共用饋送(common feed)及使用一實質相似處理架構於該等頻帶之每一者。 In one embodiment, a plurality of frequency bands are provided to a common feed and each of the frequency bands is constructed using a substantially similar processing architecture.
較佳地，對於該需要頻帶，目的係要設置該需要頻帶在DC或DC周圍且儘可能靠近DC，以便最小化所需要實施之濾波。 Preferably, for the desired frequency band, the purpose is to set the required frequency band around DC or DC as close as possible to DC in order to minimize the filtering that needs to be performed.
通常，為了選擇另一頻帶，調整本地振盪器饋送(Local oscillator feed)。 Typically, to select another frequency band, the local oscillator feed is adjusted.
通常，選擇關於系統需求之頻帶的需要頻率，其中該等系統需求包括該廣播資料接收器及該接收器在那時因特定使用者選擇要觀看及/或聆聽一上面顯示有一期望節目之特定頻道而要求之資料的特定頻道之那些需求。 Typically, the required frequency is selected for the frequency band required by the system, wherein the system requirements include the broadcast data receiver and the receiver at that time selecting, by a particular user, to view and/or listen to a particular channel on which a desired program is displayed And those requirements for the specific channel of the requested information.
通常，如果例如因使用者重新選擇要觀看或聆聽一新電視或電台節目而改變該接收器之條件，則傳送一表示該改變請求之信號，以及如果在一不同頻帶上輸送所請求之新資料，則選擇及接著處理該新頻帶，以取代前一頻帶。 Typically, if the condition of the receiver is changed, for example, because the user reselects to watch or listen to a new television or radio program, a signal indicating the change request is transmitted, and if the requested new data is transmitted on a different frequency band Then, the new frequency band is selected and then processed to replace the previous frequency band.
在一實施例中，如果或當該等轉發器根據衛星變化使用頻率時，該設備將重新校準，以便零頻率突波雜訊/缺陷(frequency spur/notch)仍然定位在該等轉發器間。 In one embodiment, if or when the repeaters use frequencies according to satellite variations, the device will recalibrate so that zero frequency spur/notch is still located between the repeaters.
在一實施例中，在相對小型“本地”環境中使用該設備之情況下，如果需要，房宅居住者可藉由關閉及打開該設備來達成此重新校準。 In one embodiment, where the device is used in a relatively small "local" environment, the home occupant can achieve this recalibration by turning the device off and on, if desired.
通常，在提供該設備做為一較大型系統之一部分，以便允許識別重新校準的需求，同時亦確保聲訊及視訊之供應的維持之情況下，較佳地週期性測量在該第一混合器以零頻率為中心後的功率位準，以及如果該測量功率增加至一預定位準以上，該設備開始實施一重新校準，此表示一轉發器與突波雜訊(spur)同時發生。以此方式，如需要，該設備可在無需人的介入下重新校準。 Typically, in the case where the device is provided as part of a larger system to allow for the identification of recalibration requirements while also ensuring the maintenance of the supply of voice and video, it is preferred to periodically measure at the first mixer The zero frequency is the power level after the center, and if the measured power is increased above a predetermined level, the device begins to perform a recalibration, which means that a repeater coincides with the spur. In this way, the device can be recalibrated without human intervention if needed.
在一實施例中，該間隙之定位允許任何不需要第二突波雜訊及/或缺陷(其通常因實施錯誤所造成)定位在該間隙中及因此，不影響該設備之性能。 In one embodiment, the positioning of the gap allows any second glitch noise and/or defects (which are typically caused by implementation errors) to be located in the gap and, therefore, does not affect the performance of the device.
在一實施例中，當設定複數單片振盪器頻率時，使用該轉發器間隙之位置的瞭解，以使它們不會互相影響。 In one embodiment, when setting the frequency of the complex monolithic oscillators, the knowledge of the position of the transponder gaps is used so that they do not affect each other.
在一實施例中，當打開該設備時，進行轉發器間隙識別(transponder gap identification)，及/或可在該設備之操作期間提供動態的轉發器間隙識別。 In an embodiment, transponder gap identification is performed when the device is turned on, and/or dynamic transponder gap identification is provided during operation of the device.
在一實施例中，當供電至該設備及最大轉發器頻寬小於在電路上的可用調整，該設備不會採用任何預定轉發器頻率分配，但是通常，該分配係靜態的。 In one embodiment, the device does not employ any predetermined transponder frequency allocation when power is supplied to the device and the maximum repeater bandwidth is less than the available adjustments on the circuit, but typically, the allocation is static.
在一實施例中，如果只利用單一頻道，則可使用另一頻道以驗證衛星轉發器頻率分配維持不變，以及如果偵測到變化，則發生對輸出信號之暫時中斷，以便校正頻率規劃。 In one embodiment, if only a single channel is utilized, another channel can be used to verify that the satellite transponder frequency allocation remains unchanged, and if a change is detected, a temporary interruption of the output signal occurs to correct the frequency plan.
通常，至少該積體電路(包括在此所述之發射器/或及接收器)係設置在該廣播資料接收器內或相鄰於該廣播資料接收器以及對於用以分配資料至多個居住者單位之設備係特別有用的。 Typically, at least the integrated circuit (including the transmitters and/or receivers described herein) is disposed within or adjacent to the broadcast data receiver and for distributing data to a plurality of occupants The equipment of the unit is particularly useful.

通常，該設備包括功率偵測器、RF振幅增益控制(RFAGC)及I和Q諧波抑制混波器、基帶低通頻帶選擇濾波器、DC偏移移除電路、IQ調變器、RF濾波及偵測在每一頻帶中之轉發器的存在及因而在其間之間隙的能力。 Typically, the device includes a power detector, RF amplitude gain control (RFAGC) and I and Q harmonic rejection mixers, baseband low pass band selection filter, DC offset removal circuit, IQ modulator, RF filtering And the ability to detect the presence of transponders in each frequency band and thus the gap therebetween.
在第2b圖所示之第二實施例中，提供單一積體電路34及一外部低雜訊放大器(LNA)35，以及在此情況下，在該接收器IC處使一寬頻RF信號36分離及經由一旁路功能(bypass function)來發送。該旁路功能允許一複製積體電路38或一地面頻帶40或兩者經由一菊鍊網路(daisy chain network)被驅動。再者，該IC包括雙同差式收發器22、24，用以從所接收之那些頻帶過濾出及傳送該需要頻帶，以及然後，傳遞該等需求資料信號至被連接至該等輸出26、28之該廣播資料接收器。該IC 34亦包括一偵測器30，用以偵測該控制信號，其中該控制信號決定該等接收頻帶之哪一個頻帶為該需要頻帶，以回應使用者經由該廣播資料接收器4所做之選擇。該偵測器連接至該轉發器偵測器32。關於此實施例，可使用相同的無線電架構於每一頻帶。 In the second embodiment shown in Figure 2b, a single integrated circuit 34 and an external low noise amplifier (LNA) 35 are provided, and in this case, a wideband RF signal 36 is separated at the receiver IC. And sent via a bypass function. The bypass function allows a replica integrated circuit 38 or a terrestrial frequency band 40 or both to be driven via a daisy chain network. Furthermore, the IC includes dual homodyne transceivers 22, 24 for filtering and transmitting the required frequency bands from those received bands, and then transmitting the demand profile signals to be connected to the outputs 26, 28 of the broadcast data receiver. The IC 34 also includes a detector 30 for detecting the control signal, wherein the control signal determines which frequency band of the receiving frequency bands is the required frequency band, in response to the user performing the broadcast data receiver 4 Choice. The detector is coupled to the repeater detector 32. With this embodiment, the same radio architecture can be used for each frequency band.
在第2c圖所示之另一實施例中，提供單一IC 36，其中在一整合矽晶粒上形成該LNA 38及用於單一頻道輸出42之單一同差式收發器40的形式之架構。該 使用架構相同於用於單一輸出之先前兩個實施例。在此情況下，在數個IC晶片44-50中複製該IC晶片36，該等IC晶片之每一者具有一輸出及可連接至一廣播資料接收器。通常，如果在該廣播資料接收器中提供更多選台器，則該廣播資料接收器將連接至該等輸出42中之兩個以上輸出。 In another embodiment, illustrated in Figure 2c, a single IC 36 is provided in which the LNA 38 and the architecture of a single homodyne transceiver 40 for a single channel output 42 are formed on an integrated germanium die. The The usage architecture is the same as the previous two embodiments for a single output. In this case, the IC chip 36 is replicated in a plurality of IC chips 44-50, each of which has an output and is connectable to a broadcast data receiver. Typically, if more tuner is provided in the broadcast data receiver, the broadcast data receiver will be connected to more than two of the outputs 42.
在無論哪個實施例中，以一積體電路為基礎之組件的供應縮減尺寸、保持成本降低及使本身更容易大量生產。在每一情況下，包括該等收發器之IC能接受第4圖所示之接收頻帶A、B、C、D及一地面服務頻帶T中之任何一者且將該等頻帶中之一識別為該需要頻帶。當從該LAN接收該等頻帶時，可能使該等頻帶偏斜。在一實施例中，如第4圖所述，該需要頻帶係以DC為中心，其中該需要頻帶係頻帶A及關於頻率範圍“a”至“b”是以線DC為中心。然而，可以改變該頻率範圍之位置，以使在該需要頻帶中之已知轉發器頻率範圍間的間隙係以DC為中心或靠近DC，而不是定該需要頻帶之中心，但是縱使在此情況下，最典型的是，最靠近該需要頻帶之頻率範圍“ab”的中心之間隙係位於DC上或在DC之周圍。該IC亦能在從該廣播資料接收器接收信號後立即偵測該需要頻帶，以回應使用者經由該廣播資料接收器所做之選擇，以及亦能校正在接收信號中之任何錯誤及輸出該需要頻帶至該廣播資料接收器。 In either embodiment, the supply of components based on an integrated circuit is downsized, the cost of maintenance is reduced, and the mass production is made easier by itself. In each case, the IC including the transceivers can accept any one of the reception bands A, B, C, D and a terrestrial service band T shown in FIG. 4 and identify one of the bands. For this required frequency band. When the bands are received from the LAN, the bands may be skewed. In one embodiment, as described in FIG. 4, the required band is centered on DC, wherein the required band band A and the frequency ranges "a" through "b" are centered on the line DC. However, the location of the frequency range can be varied such that the gap between the known transponder frequency ranges in the desired frequency band is DC-centric or close to DC rather than centered on the desired frequency band, but even in this case Next, most typically, the gap closest to the center of the frequency range "ab" of the desired frequency band is located at DC or around DC. The IC can also detect the required frequency band immediately after receiving the signal from the broadcast data receiver, in response to the user's selection via the broadcast data receiver, and can also correct any errors in the received signal and output the error. A frequency band is required to the broadcast data receiver.
通常，在該系統之操作的開始後，依據本發明之設備將識別在所接收之每一頻帶中的轉發器頻率的 位置，且接著識別在每一頻帶中之個別轉發器間的頻率間隙。然後，藉由調整PLL頻率，配置那些間隙中之一儘可能靠近DC。此確保像是位於該頻帶中及可能發生在DC處之缺陷(notches)及突波雜訊(spurs)的任何不需要信號位於該間隙中，且因而不影響任何轉發器頻率範圍。此可藉由例如在該需要頻帶之處理的下轉換(down conversion)階段後，偵測是否有信號在DC周圍被檢查到。如果有信號的話，此表示突波雜訊及缺陷位於一轉發器頻率範圍內，但是如果沒有例如小於12dB之信號的話，則可識別突波雜訊及缺陷在該間隙中。 Typically, after the start of operation of the system, the device in accordance with the present invention will recognize the transponder frequency in each frequency band received. Position, and then identify the frequency gap between individual transponders in each frequency band. Then, by adjusting the PLL frequency, configure one of those gaps as close as possible to the DC. This ensures that any unwanted signals such as notches and spurs located in the frequency band and possibly at the DC are located in the gap and thus do not affect any transponder frequency range. This can be detected by detecting a signal around the DC, for example, after a down conversion phase of the processing of the desired frequency band. If there is a signal, this means that the glitch noise and the defect are in a transponder frequency range, but if there is no signal such as less than 12 dB, the glitch noise and the defect can be identified in the gap.
在一實施例中，該設備包括至少兩個輸出，其連接至可獨立地操作以允許每一使用者選擇一上面設置有電視或電台節目之頻道的廣播資料接收器。在一實施例中，任選地傳遞該資料至本發明之設備，但是可使用一RF格式。 In one embodiment, the device includes at least two outputs coupled to a broadcast data receiver that is independently operable to allow each user to select a channel on which the television or radio program is located. In an embodiment, the material is optionally passed to the apparatus of the present invention, but an RF format can be used.
在無論哪個實施例中，通常藉由選擇用於該需要頻帶之合適時鐘速率的適當鎖相迴路(PLL)饋送，獲得該需要頻帶。選擇該需要頻帶及使該識別間隙(它通常最靠近該需要頻帶頻率範圍之中心)定位成實際可能靠近DC，且接著使用複合同相及正交混合使其與一本地振盪器混合，以便將該頻帶轉換成期望頻率輸出。濾除該等頻帶之剩餘頻帶，以使僅將該需要頻帶在輸出處饋送至該廣播資料接收器，以及然後，可選擇適當的轉發器頻率範圍，以便提供適當的電視或電台節目至該廣播資料接收者的使用者。 In either embodiment, the desired frequency band is typically obtained by selecting a suitable phase-locked loop (PLL) feed for the appropriate clock rate for the desired frequency band. Selecting the desired frequency band and positioning the identification gap (which is typically closest to the center of the desired frequency band frequency range) to be physically close to DC, and then using composite in-phase and quadrature mixing to mix with a local oscillator to The frequency band is converted to a desired frequency output. Filtering the remaining bands of the bands such that only the desired band is fed to the broadcast data receiver at the output, and then, the appropriate transponder frequency range can be selected to provide the appropriate television or radio program to the broadcast The user of the data recipient.
為了選擇接著所需要之另一頻帶，產生信號及調整本振盪器頻率，以能接收需要的頻帶。 In order to select another frequency band that is subsequently required, a signal is generated and the oscillator frequency is adjusted to receive the desired frequency band.
通常，該等需要頻帶係根據系統需求來設定及因此可因系統而有所不同。然而，它們將被預先決定，而使系統知道對於使用者經由該廣播資料接收器所選擇之每一節目頻道需要什麼頻帶。 Typically, such required frequency bands are set according to system requirements and may therefore vary from system to system. However, they will be predetermined so that the system knows what frequency band is required for each program channel selected by the user via the broadcast data receiver.
在一實施例中，可以在該需要頻帶之中間產生一不需要信號，在此情況下，可在該第二混波器前採用AC耦合，此可能轉而造成另外關於從該需要頻帶所接收之資料的位元錯誤率之問題。然而，亦在本發明中以下面方式來處理此問題。 In an embodiment, an unwanted signal may be generated in the middle of the desired frequency band, in which case AC coupling may be employed before the second mixer, which may in turn cause additional reception from the desired frequency band. The problem of the bit error rate of the data. However, this problem is also handled in the present invention in the following manner.
在每一需要頻帶內，以分隔關係設置橫跨該需要頻帶之一系列轉發器，每一轉發器通常表示一可被選擇來觀看及/或聆聽之頻道，以及在該系統中之資料輸入與輸出間需要維持轉移函數(Transfer Function)，以便以需求形式提供服務給使用者。 Within each required frequency band, a series of transponders spanning the desired frequency band are arranged in a spaced relationship, each transponder typically representing a channel that can be selected for viewing and/or listening, and data entry in the system The transfer function needs to be maintained between outputs to provide services to the user in the form of requirements.
在此實施例中，不是移動需要頻帶之中心至DC，而是將定位成最靠近DC之在轉發器間的間隙移動至DC。因此，此確保在該需要頻帶之中間或DC處所產生之任何不需要信號將位於該等轉發器間之間隙中。因此，此意味著避免可能發生於頻道之信號的任何損失或位元錯誤速率的增加，因為信號之可能影響係位於轉發器間之間隙中，而不是在轉發器位置。 In this embodiment, instead of moving the center of the desired band to DC, the gap between the transponders positioned closest to DC is moved to DC. Therefore, this ensures that any unwanted signals generated in the middle of the required frequency band or at the DC will be located in the gap between the repeaters. Therefore, this means avoiding any loss of signal that may occur on the channel or an increase in the bit error rate, since the possible effect of the signal is in the gap between the transponders, not at the repeater position.
在某些實施例中，該架構之一優點為刪除在該輸出中之開關的需求之能力，以及因而節省空間及成本。 In some embodiments, one of the advantages of the architecture is the ability to remove the need for switches in the output, and thus save space and cost.
在一實施例中，該輸出亦可包括用於地面系統的資料，其可個別被輸出或被雙路傳輸至現存輸出中。在另一實施例中，本發明可使用於一與一同軸及/或光學電纜分配系統連接之併合網路(hybrid network)及沒有直接連接至一個以上廣播資料接收器。在此情況下，可以在本發明之裝置與一個以上接收器間提供一個以上開關。 In an embodiment, the output may also include data for the ground system that may be individually output or dual transmitted to the existing output. In another embodiment, the present invention can be used in a hybrid network connected to a coaxial and/or optical cable distribution system and not directly connected to more than one broadcast data receiver. In this case, more than one switch can be provided between the apparatus of the present invention and more than one receiver.
在本發明之另一範例中，參考下表，其闡述一用於該設備及方法之頻率方案。在每一情況下，輸出頻帶行表示從該設備輸出且輸送至被連接至輸入的廣播資料接收器之頻率。纖維堆頻率行表示不同的頻帶，其中該等不同頻帶可從輸入選擇性地被提供至本發明之設備及該等不同頻帶之任一者可選擇性地被識別為待處理之“需要”頻帶。標題為ASIC RxLo及TxLo之行為在該設備中所使用之本地振盪器頻率。 In another example of the present invention, reference is made to the following table, which illustrates a frequency scheme for the apparatus and method. In each case, the output band line represents the frequency that is output from the device and delivered to the broadcast data receiver that is connected to the input. The fiber stack frequency line represents a different frequency band, wherein the different frequency bands can be selectively provided from the input to the device of the present invention and any of the different frequency bands can be selectively identified as a "required" frequency band to be processed . The title is ASIC RxLo and TxLo behaves as the local oscillator frequency used in the device.
應該注意到，在此範例中，使第二及第四輸入之頻帶反向。依據本發明之設備，當這些頻帶為需要步頻帶時，該設備亦使這些頻帶反向，以便不使在輸出處之頻帶反向及此在該設備中藉由適當地調整Lo及RF信號之相位來達成。 It should be noted that in this example, the frequency bands of the second and fourth inputs are reversed. In accordance with the apparatus of the present invention, when the frequency bands are required to have a step band, the device also reverses the frequency bands so as not to reverse the frequency band at the output and thereby properly adjust the Lo and RF signals in the device. The phase is reached.
通常，可選擇性地程式化為了本發明之設備的實施操作所提供之軟體(software)，以允許依據使用該軟件之特定系統的操作特性來接收特定頻帶。 In general, the software provided for the implementation of the apparatus of the present invention can be selectively programmed to allow reception of a particular frequency band depending on the operational characteristics of the particular system in which the software is used.
因此，依據本發明提供一種設備及方法，其允許至少該轉發器(但是，較佳地，其它組件)被提供做為一個或兩個積體電路之一部分，同時仍然達成從那裏來之輸出信號所需的一致性及品質。此表示在傳統上藉由使組件連結在一起及互連所提供之該型態的設備之規定方面有顯著的節省。 Accordingly, in accordance with the present invention, an apparatus and method are provided that allow at least the repeater (but, preferably, other components) to be provided as part of one or both integrated circuits while still achieving an output signal therefrom The consistency and quality required. This represents a significant savings in the regulatory aspects of this type of device that has traditionally been provided by joining components together and interconnecting them.
