2. Operational Principles of Cable TV
I. Definition and Operation of IPTV
1. Definition of IPTV
IPTV (Internet Protocol Television) is a service that transmits television signals over broadband internet, using the IP protocol to deliver video, audio, and data content as digital streams to user terminals (such as TVs, set-top boxes, or smart devices). According to the "Technical Specification for Interoperability of Broadcasting and Television Networks" (GY/T 220.1-2006), IPTV is a television service based on telecom operators' broadband networks, combining live streaming, on-demand, and interactive features to provide users with a diverse audio-visual experience.
IPTV is typically provided by telecom operators and connected to home televisions via dedicated broadband networks and set-top boxes (STBs). It offers live TV channels, video on demand (VOD), catch-up features, and value-added services.
2. How IPTV Works
IPTV uses the following technical architecture to deliver content:
• Content Acquisition: The IPTV platform acquires programs from TV stations, content providers, or self-produced content libraries and encodes them into digital streams.
• Transmission Network: Utilizing telecom operators' broadband networks (such as fiber or ADSL), IP-based data transmission ensures low latency and high reliability.
• Terminal Device: Users receive the signal through an IPTV set-top box, smart TV, or mobile device, which decodes and displays the video content.
• Interactive Features: Supports on-demand viewing, rewinding, pausing, and application services (such as education and gaming), enabling user interaction through two-way communication.
II. Definition and Operational Principles of Cable TV
1. Definition of Cable TV
Cable TV is a traditional television service that transmits analog or digital television signals to subscribers' homes via coaxial or optical cables. According to the "Cable TV Network Technical Specification" (GY/T 106-1999), cable TV broadcasts live television channels, covering news, entertainment, sports, and other content.
Cable TV is operated by broadcasting and television systems and connects to subscribers' televisions via cable networks. It requires a digital television set-top box (DTMB) to decode the signal.
2. Operational Principles of Cable TV
Cable TV uses a one-way broadcast model:
• Content Distribution: Broadcasting and television companies receive television station signals via satellite or terrestrial stations, centrally encode them, and broadcast them via cable networks.
• Transmission Network: Analog/digital signals are transmitted via coaxial or optical cables, covering urban and some rural areas.
• Terminal Device: Users receive the signal via a set-top box or a television with a built-in tuner, which decodes and plays the live channel.
• Functional Limitations: Primarily offers live streaming, with limited on-demand or catch-up support in some regions.
III. Differences between IPTV and Cable TV
1. Transmission Technology
• IPTV: Transmitted via broadband internet (IP protocol), based on fiber optic or ADSL networks, with digital signals and two-way communication supporting interactive features.
• Cable TV: Transmitted via coaxial or optical cables, with analog or digital signals, one-way broadcasting, and weak interactivity.
• Impact: IPTV requires high broadband speeds (recommended 20Mbps or higher), and its stability depends on network quality; cable TV offers stable signals but does not support complex interactions.
2. Content Provision
• IPTV: Offers rich content, including live channels, on-demand movies and TV shows, catch-up (within 7 days), and value-added services (education, games). Operators collaborate with internet platforms to offer popular dramas and variety shows.
• Cable TV: Primarily offers live channels, with limited on-demand content and catch-up support in some regions. Broadcasting and television systems prioritize localized content (such as local news).
• Impact: IPTV offers diverse content and is suitable for users who seek on-demand and personalized experiences; cable TV is suitable for users who prefer live and local programming.
3. Interactive Features
• IPTV: Supports on-demand viewing, rewinding, pausing, fast-forwarding, an app store (such as education and fitness apps), and voice control, offering high interactivity.
• Cable TV: Limited functionality, primarily focused on live streaming, with limited rewind support in some regions. It offers poor interactivity and lacks smart apps.
• Impact: IPTV offers an immersive experience and is suitable for young families; cable TV is simpler to use and is suitable for older users.
4. Network Dependency
• IPTV: Requires a stable broadband network. Speeds below 10Mbps may cause lag and render it unusable during network outages.
• Cable TV: Independent cable networks are independent of the internet, offering high signal stability and continued service during power outages or network outages (requires TV power).
• Impact: IPTV is suitable for cities with widespread broadband access; cable TV is suitable for rural or remote areas with unstable network connections.
5. Picture and Sound Quality
• IPTV: Supports 4K, HDR, and Dolby Atmos (requires broadband and HD content), offering detailed picture quality and immersive sound, but is subject to network speed limitations.
• Cable TV: Mainstream is 1080p, with limited 4K content. Sound quality is average (mainly stereo), but the signal is stable and the picture quality is consistent.
• Impact: IPTV is suitable for audiovisual enthusiasts seeking high-quality video; cable TV offers stable picture quality but limited room for improvement.
6. Price and Cost
• IPTV: Typically bundled with a broadband plan, with monthly fees ranging from $20 to $100. Some content requires an additional subscription (such as VIP on-demand).
• Cable TV: Independently billed, some channels require additional fees. Installation fees are additional, and a set-top box must be purchased or leased.
• Impact: IPTV offers a high overall cost-effectiveness and is suitable for broadband users; cable TV offers transparent costs, but higher long-term costs.
7. Coverage and Availability
• IPTV: Relies on broadband networks, with high urban coverage (over 90%), while rural areas are limited by network infrastructure.
• Cable TV: Cable networks cover cities and most rural areas, with a broad user base nationwide, but access to new communities may be delayed.
• Impact: IPTV is suitable for cities and areas with widespread fiber optic coverage; cable TV is suitable for areas without broadband or in remote areas.
8. User Experience and Service
