200901030 « 九、發明說明: 【發明所屬之技術領域】 本發明係提供一種依據一全球定位系統所提供之資訊 執行相對應操作之可攜式多媒體播放裝置及其相關方法, 尤指一種可依據一全球定位系統所提供之位置資訊與一頻 道表/位置對照表之比對結果執行相對應指令之可攜式多 媒體播放裝置及其相關方法。 【先前技術】 隨著數位化時代來臨,電視與廣播也逐漸從傳統的類 比式系統轉換成數位式系統。類比系統往往受地形地物因 素影響而有接收不良或訊號忽強忽弱的現象,數位視訊廣 播(Digital Video Broadcasting,DVB)系統以及數位音訊廣 播(Digital Audio Broadcasting,DAB)系統則可以克服此類 干擾’提供更高晝質與更佳音質的節目。同時,頻譜的使 用可以更有效率,數位系統使用與類比系統相同的頻寬可 以傳送更多的節目。 一般來說,世界各國發射數位視訊廣播訊號或數位音 訊廣播訊號之頻帶與頻寬皆不盡相同,一般都以國家作為 區別,例如台灣區目前開播之頻帶為533Hz至6〇3Hz,且 頻寬為6MHz(以DVB-T為例),而其他國家例如德國、加 拿大等又有所不同,而這些專屬某一特定區域之頻帶與頻 7 200901030 寬資料都會被儲存於數位電視裝置或數位廣播播放裝置之 _,當區域設定錯誤時則會發生收不到訊號之狀況。故當 使用者購買了一台可攜式數位電視後,必須先設定好收訊 區域(例如台灣),再進行頻道掃描,如此一來方能正確地 收到節目訊號。然而於設定完成後,使用者可能會帶著該 可攜式數位電視到處收看,當使用者在同一收訊區域觀看 該羿攜式數位電視,例如在台灣區之台北與花蓮觀看該可 攜式數位電視,其收視並不會受到影響,故無須重新更改 區域設定及進行頻道掃描,但當使用者跨區移動時,例如 將該可攜式數位電視由台灣帶到德國收看,因為德國發射 數位視訊廣播訊號之頻率與台灣不同,故先前於台灣所掃 描出來之頻道將收不到訊號,此時使用者就必須將收訊區 域設定更改為德國,然後再進行頻道掃描,如此一來方能 收視。然而目前市面上大部分之可攜式數位電視在更改區 域設定方面,都必須使用手動方式,意即必須開啟電視操 作選單,然後進入區域設定選項,方可進行操作,如此繁 雜之操作方式會造成使用者使用上之不便。此外,在收不 J卸。代破時’也無法得知疋區域改變抑或只是單純收訊 不良’故也無法判斷是否必須更改區域設定及重新掃描。 此外’當使用者跨區移動為跨越時區時,若該可攜式數位 電視有預約錄影之功能,則可能會造成使用者設定預約錄 影时間之錯誤。故如何找出一有效解決可攜式數位廣播收 訊裝置於跨越區域(國家或時區)時所面臨之上述問題之方 200901030 案,便為現今可攜式數位廣播收訊裝置設計所需努力之課 題。 【發明内容】 本發明係提供一種依據一全球定位系統所提供之資訊 執行相對應操作之可攜式多媒體播放裝置及其相關方法, 以解決上述之問題。 本發明之申請專利範圍係揭露一種可攜式多媒體播放 裝置,其包含有一殼體,一接收模組,安裝於該殼體内, 用來接收一發送端所傳來之一無線電訊號,一調頻器,安 裝於該殼體内且耦合於該接收模組,用來掃描該無線電訊

Description of the invention: [Technical field of the invention] The present invention provides a portable multimedia playback device and related method for performing corresponding operations according to information provided by a global positioning system, and more particularly, A portable multimedia playback device and related method for performing corresponding instructions by comparing the location information provided by the global positioning system with the channel table/location comparison table. [Prior Art] With the advent of the digital age, television and broadcasting have gradually shifted from traditional analog systems to digital systems. Analogous systems are often affected by topographical factors and have poor reception or weak signals. Digital Video Broadcasting (DVB) systems and Digital Audio Broadcasting (DAB) systems can overcome this type of system. Interference 'provides a program with higher quality and better sound quality. At the same time, the use of the spectrum can be more efficient, and the digital system can transmit more programs using the same bandwidth as the analog system. Generally speaking, the frequency bands and bandwidths of digital video broadcasting signals or digital audio broadcasting signals transmitted by countries all over the world are not the same, and are generally distinguished by countries. For example, the frequency band currently launched in Taiwan is 533 Hz to 6 〇 3 Hz, and the bandwidth is wide. It is 6MHz (taking DVB-T as an example), while other countries such as Germany and Canada are different, and these exclusive bands and frequency 7 200901030 wide data will be stored in digital TV devices or digital broadcasting. If the device is set incorrectly, the signal will not be received. Therefore, when a user purchases a portable digital TV, the receiving area (such as Taiwan) must be set up before the channel scanning is performed, so that the program signal can be correctly received. However, after the setting is completed, the user may watch the portable digital TV everywhere. When the user watches the portable digital television in the same receiving area, for example, watching the portable in Taipei and Hualien in Taiwan. Digital TV, its viewing will not be affected, so there is no need to change the regional settings and channel scanning, but when the user moves across the area, for example, bring the portable digital TV from Taiwan to Germany, because the German launch digital The frequency of video broadcast signals is different from that of Taiwan. Therefore, the channels previously scanned in Taiwan will not receive the signal. At this time, the user must change the receiving area setting to Germany and then perform channel scanning. Viewing. However, most of the portable digital TVs currently on the market must use the manual mode in changing the regional settings, which means that the TV operation menu must be turned on and then enter the regional setting option before the operation can be performed. Such complicated operation mode will result in The user is inconvenient to use. In addition, it is not unloaded. When it is broken, it is impossible to know whether the area is changed or it is simply a bad reception. Therefore, it is impossible to judge whether it is necessary to change the area setting and rescan. In addition, when the user moves across the zone to span the time zone, if the portable digital television has the function of recording a reservation, the user may set an error in the scheduled recording time. Therefore, how to find out an effective solution to the above-mentioned problems faced by portable digital broadcast receiving devices across regions (countries or time zones) is to design the requirements for today's portable digital broadcast receiving devices.
