Embodiment Construction

[0021] see first figure 1 , a personal video recorder (PVR) 19 receives a source signal 11 from, for example, a satellite receiver or a cable provider, and tunes the received source signal 11 by a tuner 12 under the control of a processor 18, and the MPEG-2 encoder 16 It is compressed, the file is stored in MPEG-2 format in a data storage 17, such as a hard disk storage device, and when required for display, the stored file is decompressed by an MPEG-2 decompressor 14. Other compression formats such as MPEG-4 or DV may be used. Other memory devices such as RAM (Random Access Memory) may be used. The PVR 19 also includes a remote control command receiver 22 for receiving user commands from the remote control 20 . Remote control 20 may have an IR or RF transmitter for transmitting coded signals representing user commands. As an option, user commands may be generated by input devices such as buttons (not shown) mounted to the PVR 19 . All elements are connected together by a ...

Abstract

A video playback apparatus receives a control signal from a remote control device having a multipurpose key and assigns alternative functions to the received signal depending on the duration of time the control signal is received. For example, the remote may have a combination skip-forward multipurpose key which when pressed for less than a predetermined period such as one second, causes the video playback apparatus to invoke its skip mode, and when pressed for more than the predetermined period causes the video playback apparatus to invoke its forward, fast forward, or super fast forward mode, depending on the duration of time the key is pressed beyond invocation of the forward mode.
