  • the broadcast television system has existed for a long time.
  • television stations provide broadcast video streams to a large number of users.
  • the broadcast video stream can be transmitted over a surface or satellite-based RF transmission system, or broadcast over a cable television line that is widely distributed between the transmitter and the client.
  • packet switching is a method of communication.
  • the packet exchange is to cut the data into a segment of the packet before sending, and then the sender signs the address of the receiver in each packet and transmits it to the network. After receiving the packet, the receiver combines the packets. When the packet is in transit, it will be slightly stopped at the passing node. After the node receives the complete packet, it will transmit to the next node. Packet exchange can provide information transmission from multiple sources at the same time. Each packet can find the best path according to the situation, and then reorganize the original information after reaching the destination.
  • the advantage of the packet exchange method is that the throughput rate is high, the time delay is small, and no data is retransmitted when an error occurs.
  • IPTV Internet Protocol Television
  • video, audio, and data signals are distributed to clients using the Internet.
  • IPTV is typically delivered over DSL or fiber-to-the-home (FTTH) networks and is served by plant owners (usually local telephone companies) who own the network.
  • FTTH fiber-to-the-home
  • the IPTV system only needs three network elements: an encoder that converts broadcast television into an IP data packet, a network that connects the client to the service provider, and a client located at the client. And converting the IP data packet into a video conversion box of the video.
  • a typical network also includes several auxiliary systems: VOD servers, ad insertion systems, billing platforms, and digital rights management (DRM) systems.
  • the IPTV system provides all information channels, including broadcast information channels and VOD information channels, using a network connected to the client.
  • the IPTV system is feasible because it uses advanced video codec to greatly increase the compression ratio.
  • the video codec used is MPEG-4 (H.264) codec technology, and the compression ratio can be greater than 100:1. Even so, IPTV is by far the most bandwidth-hungry service in the network.
  • One-hour IPTV requires 5 gigabytes of capacity, which is equivalent to 1,000 hours of voice, which is greater than the total capacity of a network user to send and receive mail throughout the year.
  • IPTV customers With the rapid increase of the end, the required bandwidth will also increase rapidly, and this trend will bring huge challenges to the transmission load of the network.
  • Program content can be spread by unicast technology. Whenever a new connected user is added to the IPTV system, the server must provide the bandwidth required to transmit the content requested by the new user. Therefore, the IPTV system using unicast technology needs to be compared when serving more users. The large bandwidth makes it costly for a single service person. Although IPTV systems using unicast technology are limited by the maximum number of simultaneous services and their service costs, in the era of personalized services, VOD (Video-On-Demand) services that provide personalized needs are The most important advantage.
  • IPTV system operators will use multi-cast technology to transmit program content.

  • a media server that transmits streaming data via Class D will pass a single stream of processing to multiple clients without the need to connect to the media server. Since the content is transmitted by broadcast, it is difficult to provide VOD services at the same time. Since the client and the server may not be connected, there is no interaction between the two.
