When this type of service first made it's appearance, it had limited abilities because of the limited capabilities of internet protocol. Programs could be downloaded and played, or streamed. With limitations in bandwidth and connection speeds, peer to peer was the only available option then. This decentralized system made use of a customer's computer and it's upload bandwidth as part of the system.
A centralized system became possible as mass storage and faster streaming speeds were available. Video or audio quality can still vary from one provider to another. Buffering helps to minimize gaps and pauses. Programming can be changeable, and sometimes disappears for a few days, then returns. Other providers offer a television quality product.
Some of these services come from conventional broadcast networks and news outlets. They provide catch up, or on demand services. The viewer can access archives of previously viewed programming stored on server farms. Sometimes the archives hold several years worth of television series programs, available on demand. Some only have the previous week's program to allow viewing of a missed installment.
Some programming is live streaming of current time broadcasting. Converged services allow integration of multiple television and web resources on one screen. A television program may be watched while social media or e-mail is accessed simultaneously, in dual vision. Seamless searching for all resources, written, or video is another useful and efficient time saving development.
This programming is accessible in several different ways. A PCTV tuner card can be purchased and installed on the computer externally through a USB port or in an internal slot. Then by connecting a TV coaxial cable and downloading and installing drivers for the tuner card, a computer becomes a television.
Other applications are free, or subscription services that allow the user to choose programming by station, or program from menus. Other menus list by type, whether movie, television, movie, action, comedy, sports, etc. By doing a browser search for, program name online streaming, free streaming can often be found.
Satellite tv to pc provides access to more than 4,000 channels, worldwide. After making a onetime software purchase, free programming is accessible indefinitely. I personally use a satellite TV on PC software that allows me to watch more than 3,000 international television channels online.
