digital television
Digital television (DTV) refers to the sending and receiving of moving images and sound by means of discrete (digital) signals, in contrast to the analog signals used by analog TV. Introduced in the late 1990s, this technology appealed to the television broadcasting business and consumer electronics industries as offering new financial opportunities. Digital television is more flexible and efficient than analog television. When properly used by broadcasters, digital television allows higher-quality images and sound and more programming choices than analog does. However, although DTV allows for superior technical quality, a digital signal does not necessarily carry a higher-quality image or sound than an analog signal (Wikipedia)

Push–pull technologies
Push technology on the Internet refers to a style of communication protocol where the request for a given transaction originates with the publisher, or central server. It is contrasted with pull technology, where the request for the transmission of information originates with the receiver, or client. (Wikipedia) Instead of "pulling" content from Web sites using your browser, with push technologies, you just "tune" your client software to receive information from a server site and sit back and drink in the content. It's like putting your Web browser on autopilot. The difference between push and pull is a little like the difference between tv and paper magazines. You have to go out to buy the paper stuff (you have to "pull" it in). With tv, you just tune your client (tv set) to a site (television channel) and sit back on the couch and soak it in (content is "pushed" to you). Except push on the Net is a little different, perhaps more like television-on-demand, because you can sometimes request specific content without having to wait for it to be broadcast at a specific time.

personal mobile devices, for example, PDA, laptop
A personal digital assistant (PDA) is a handheld computer, also known as small or palmtop computers. PDAs have many uses: calculation, use as a clock and calendar, accessing the Internet, sending and receiving E-mails, video recording, typewriting and word processing, use as an address book, making and writing on spreadsheets, scanning bar codes, use as a radio or stereo, playing computer games, recording survey responses, and Global Positioning System (GPS). Newer PDAs also have both color screens and audio capabilities, enabling them to be used as mobile phones (smartphones), web browsers, or portable media players. Many PDAs can access the Internet, intranets or extranets via Wi-Fi, or Wireless Wide-Area Networks (WWANs). Many PDAs employ touch screen technology.(Wikipedia).
