香港廣播里程碑
1
1957年：麗的映聲啟播
麗的映聲作為香港首家電視台正式啟播，當時採用有線收費模式，開啟了香港人的電視娛樂先河。這標誌著香港進入了視聽媒體的新紀元，儘管初期僅限於付費訂戶。
2
1967年：無線電視啟播
電視廣播有限公司（TVB）正式啟播，提供免費無線廣播服務。這徹底改變了市民的生活習慣，讓電視機成為香港家家戶戶客廳的中心。
3
2007年：數碼廣播啟動
香港正式啟動地面數碼電視（DTT）廣播，與模擬訊號並行發放。這不僅提升了畫質至16:9寬屏幕格式，更引入了互動功能與多頻道選擇。
4
2020年：終止模擬廣播
於2020年11月30日深夜，香港正式終止所有模擬電視廣播訊號。此舉是為了騰出寶貴的頻譜資源，用於支援5G等先進電訊服務發展。
Hong Kong Broadcasting Milestones
1
1957: Rediffusion Television Launch
Rediffusion Television launched as the city's first station using a wired subscription model, pioneering TV entertainment for Hong Kongers. This marked the dawn of the audio-visual media era, though initially limited to paid subscribers.
2
1967: TVB Wireless Launch
Television Broadcasts Limited (TVB) officially launched, offering free over-the-air wireless services. This revolutionised daily habits, making the television set the central fixture in Hong Kong households.
3
2007: DTT Launch
Digital Terrestrial Television (DTT) was officially launched, simulcasting with analogue signals. This upgraded picture quality to 16:9 widescreen and introduced interactive features and expanded channel options.
4
2020: Analogue Switch-off
At the stroke of midnight on November 30, 2020, Hong Kong officially terminated all analogue television signals. This move freed up valuable spectrum for advanced telecommunications services like 5G.
模擬與數碼廣播之對決
| 項目 | 詳情 | 比較 |
|---|---|---|
| 影像解析度 | 模擬訊號受限於PAL制式，而數碼訊號則支援高清甚至4K標準。 | 576i 模擬 vs 1080p 數碼 |
| 頻譜效率 | 數碼技術允許在單一頻率內傳輸多個頻道，大幅節省無線電資源。 | 1 頻率 1 頻道 vs 1 頻率 多頻道 |
| 抗干擾能力 | 模擬訊號容易出現「雪花」或「鬼影」，數碼訊號則提供穩定的清晰影像。 | 受干擾 vs 零干擾/斷訊 |
Analogue vs. Digital Broadcasting
| Item | Details | Comparison |
|---|---|---|
| Image Resolution | Analogue signals were limited by the PAL standard, whereas digital signals support HD and 4K standards. | 576i Analogue vs 1080p Digital |
| Spectrum Efficiency | Digital technology allows multiple channels to be transmitted on a single frequency, saving radio resources. | 1 Freq 1 Channel vs 1 Freq Multi-Channel |
| Interference Resistance | Analogue signals suffered from 'snow' or 'ghosting,' while digital signals provide consistent clarity. | Interference vs Stable/Cliff-effect |

高增益UHF天線
針對某些接收較弱的地區，建議使用優質的特高頻（UHF）天線以穩定接收高清訊號。
高速寬頻連接
現代電視多具備智能功能，穩定的寬頻連接是享受4K串流及互動服務的基礎。
Modern Home Reception Checklist
Integrated Digital TV
Ensure your TV set features the 'DTT' logo, allowing direct digital reception without an external set-top box.
High-gain UHF Antenna
For areas with weaker signals, using a quality UHF antenna is recommended to stabilise HD reception.
High-Speed Broadband
Modern TVs feature smart capabilities; a stable broadband connection is essential for 4K streaming and interactive services.
為何頻譜資源如此重要？
支援5G發展
終止模擬廣播後騰出的頻譜被稱為「數碼紅利」。這些低頻段訊號穿透力強，對擴展5G網絡覆蓋範圍至關重要，能有效改善室內及偏遠地區的接收。
Why Spectrum Resources Matter?
Powering 5G Growth
The spectrum freed after the analogue switch-off is known as the 'Digital Dividend.' These low-band signals have high penetration, essential for expanding 5G coverage in indoor and remote areas.
