  • TV Networks File Legal Claims Saying Skipping Commercials Is Copyright Infringement

    techdirt.com 6 days, 8 hours ago

    Okay, we had expected the TV networks to possibly take legal action against DISH Networks for its new Auto Hopper technology, which allows DISH subscribers who use the Hopper feature (which records all prime time shows from the four major networks) to autoskip commercials, if they watch shows in the days after they originally air.

Additional Info

via Wikipedia
Sound recording and reproduction is an electrical or mechanical inscription and re-creation of sound waves, such as spoken voice, singing, instrumental music, or sound effects. The two main classes of sound recording technology are analog recording and digital recording. Acoustic analog recording is achieved by a small microphone diaphragm that can detect changes in atmospheric pressure and record them as a graphic representation of the sound waves on a medium such as a phonograph. In magnetic tape recording, the sound waves vibrate the microphone diaphragm and are converted into a varying electric current, which is then converted to a varying magnetic field by an electromagnet, which makes a representation of the sound as magnetized areas on a plastic tape with a magnetic coating on it. Analog sound reproduction is the reverse process, with a bigger loudspeaker diaphragm causing changes to atmospheric pressure to form acoustic sound waves. Electronically generated sound waves may also be recorded directly from devices such as an electric guitar pickup or a synthesizer, without the use of acoustics in the recording process other than the need for musicians to hear how well they are playing during recording sessions.
