[Prior Art] Conventional or existing TV receiving devices, such as the TV set box (Jiang Na (6)), are roughly the following types: * Household type: In addition to the larger size, it also has The big antenna, if there is a display, is mostly a large-sized display with a high resolution. At the same time, because of the large power consumption, it must be plugged into the socket for use. • Automotive type: Small size, display is 7,, ~12, medium-sized flat panel display, if there is high-speed mobile receiving capability, two antennas are needed to overcome the Duple effect and multi-path Problem (multipathproblem), power supply is for car battery (12v~24v) 2. Portable: If you use DVB-Η standard mobile TV or mobile TV, the display is 2,,~$” small flat display They are mainly battery operated, and the antenna is mainly telescopic antenna, so that the VHF TV program signal with lower frequency band can be received at the time. However, the above-mentioned prior art products cannot have a single device. The multi-turn TV receives 1295893. Even in the conventional or prior art, the separate π _ 77 ' does not achieve a single-TV receiver, but can have a variety of functions for television reception. For example, national patents The first recommendation number (10) 5/1 side announcement) is only a mechanical structure in which the base of the LCD TV is separated from the base, and is only a single receiving function; national patent No. 277209 (10) Xiao Miscellaneous) For the display of the adapter card, it must be combined with the personal electrician to enter the (four) tone decoding, which is a single-function; the US special Yang 157 (10) W-face announcement) is a separate design, but it is not a combination of the two. Design, but must be with - the third mechanical component and the multiple wires, not on the same, but also because of the use of a single "antenna" so in fact only have a single-receive function; US patent defense (four) No. (Public Toilet Announcement) Lai is also a separate design, but it is connected to the mobile phone, does not have TV reception Wei: US Patent No. 6882326 (10) 4/04/19 announcement) also has a separate design, but only personal information盥Audio and video data playback 'completely no TV viewing function; US Patent No. 695 ( (employment / round announcement) is only a combination of the design and style of the audio-visual prefecture shop, plus the woven personal or notebook computer In order to play personal information and audio and video materials, there is no TV reception function.

10 1295893 收視之訊號解調變或是解碼後，經由114介面輸出，送到一大型顯示器，因此兩者 結合後’變成等同於-家用之機上盒（STB ’ set_t〇pb〇x)或是一 pc使用之機上盒 (PC STB) ’ |5]時也可讀1〇〇可分離之電視收視裝置進行充電。因此，可以達到 一機多用途之功效。 然而，熟習於電視收視裝置設計者皆知，由於電波特性，在室内時，大都容 易發生接收不良之情形。所以，電視收視者都會利用一戶外天線或是靠近窗邊之接 收天線來改魏視不良之狀況。分離式電視裝置之底座裝置可以提供-個預接天線 之方式，可以先將此戶外天線或是靠近窗叙接收天線預接於此底座裝置，免於每 次安裝或是拆除之動作，大幅減少使用者之不便。因此，當1〇〇可分離之電視收視 裝置與110底座裝置結合時，由於兩者各有一天線，也各自接收電視射頻訊號，但 是如何選擇何者進行訊號解調變，以及如何自動修正與調整，將成為一亟待解決之 問題。同時兩者結合後，其間所必須之溝通訊號，亦為一需要解決之問題。 第二圖為第一實施例中100可分離之電視收視裝置與11()底座裝置結合後之 方塊圖。200為可分離之電視收視裝置之主要元件架構，25〇則為底座裝置之示意 圖，201與251為可分離之電視收視裝置與底座裝置各自之天線。 200可分離電視收視裝置至少包括主要元件：2〇2為射頻訊號切換器，2〇3為 基頻微處理器，204為電視解調器，205為LCD平面顯示器，206為電池模組，207 為揚聲器。202射頻訊號切換器之一輸入端耦合至2〇1天線所接收之Rp訊號輸入 219 ’另一輸入則麵合至一來自底座裝置之RF訊號輸入，而其由來自2〇3基頻微 處理器之一訊號’ ANT—SEL，來決定選擇何者為204電視解調器之輸入。204電 視解調器將電視RF訊號進行降頻、濾波、解調變、數位化，轉成符合規範之數位 訊號’如MPEG2 transport stream (TS );若是類比電視訊號（如NTSC或是PAL)，10 1295893 After the signal is demodulated or decoded, it is sent to a large display via the 114 interface output, so the combination of the two becomes 'equivalent to the home set box (STB 'set_t〇pb〇x) or A PC-based set-top box (PC STB) ' |5] can also be read by a detachable TV viewer for charging. Therefore, it can achieve the multi-purpose effect of one machine. However, it is well known to those skilled in the art of television viewing devices that due to the characteristics of radio waves, it is easy to cause poor reception when indoors. Therefore, TV viewers will use an outdoor antenna or a receiving antenna near the window to change the situation of Wei Shi. The base device of the split type television device can provide a pre-connected antenna, and the outdoor antenna or the window receiving antenna can be pre-connected to the base device, which is free from the action of each installation or removal, and is greatly reduced. The inconvenience of the user. Therefore, when a detachable television viewing device is combined with a 110 cradle device, since each has an antenna, each receives a television radio frequency signal, but how to select which signal demodulation, and how to automatically correct and adjust, Will become an urgent problem to be solved. At the same time, after the combination of the two, the necessary communication number of the ditch is also a problem to be solved.

One of the input terminals of the 202 RF signal switcher is coupled to the Rp signal input 219 received by the 2〇1 antenna. The other input is integrated into an RF signal input from the base unit, which is micro-processed from the base unit of the 2〇3. One of the signals, 'ANT-SEL,' determines which one is the input to the 204 TV demodulator. The 204 TV demodulator reduces, filters, demodulates, digitizes the TV RF signal into a digital signal conforming to the specification such as MPEG2 transport stream (TS); if it is an analog TV signal (such as NTSC or PAL),
