It is not usually necessary to download any type of special software to watch live streaming television. In most cases, live streams are available for viewing through a regular web browser.
Cable providers, such as Time Warner Cable and Comcast, offer subscribers the opportunity to purchase or participate in programs that allow them to watch television from their computers or mobile devices. When using mobile devices, it may be necessary to download an application in order to view live streaming television. Websites like Ustream and YouTube offer live streaming television from web browsers, but may also require an app download in order to work properly on cell phones and other mobile devices such as tablets.
