METHOD AND APPARATUS FOR FAST FORWARDING AND REWINDING
IN A VIDEO RECORDING DEVICE
BACKGROUND OF THE INVENTION
1. FIELD OF THE INVENTION
The present invention relates to media viewing devices and, more specifically, to video viewing devices. In certain embodiments, the present invention may also have application to audio recording devices.
IN A VIDEO RECORDING DEVICE
BACKGROUND OF THE INVENTION
1. FIELD OF THE INVENTION
The present invention relates to media viewing devices and, more specifically, to video viewing devices. In certain embodiments, the present invention may also have application to audio recording devices.
2. DESCRIPTION OF THE RELATED ART
Video data recorders are well-known in the art. Initially, video data recorders were designed to record video signals on video tape and to allow play back of recorded video signals from the tape. Of course, video tapes require sequential recording and playback limiting the functionality of such machines.
Disk-based video playback machines have been introduced such as video disks and more recently digital video disk machines. These machines may be generally characterized as providing a removable randomly accessed disk allow for the storage and playback of video signals.
United States Patent No. 5,241,428 (the '428 patent) describes a video recording and playback device. The described system provides for simultaneous playback and recording of video signals on a randomly accessed recording medium. By allowing simultaneous recording and playback of video signals and by allowing for random access of the recording medium, additional functionality may be provided beyond that realized by a video tape recording machine.
While the '428 patent describes a randomly accessed video recording and playback device, it fails to describe or suggest significant functionality which may be implemented in such a device.
Thus, what is needed is an improved video data recorder having increased functionality.

Figure 1 provides a high-level block diagram view of a video data recorder (VDR) as may utilize the present invention.
A processor 101 is coupled in communication with a channel guide database 103, a criteria database 104, video storage 105 (also referred to as tire recording medium), program " . v... .~~~.hm,ua~ ,n .n.
logic memory 102, a video compressor/decompressor 1 12, a video input source 106, a video output 107, a channel guide data source 109 and a user interface 108.
'I'lre processor 101 may be any of a plurality of commercially available procesSOrs such as the a processor from the Motorola 68000 series of processors, a processor from the lntc:l 5086 family of processors or a higher level processor such as a processor from the Intel 1'cntiurnT"r family of processors or from the Motorola PowerPC~r"' family of processors. The processor in tire described embodiment acts under program control by a program stored in program logic mcrnory 102 to perform functions, such as "fast forwarding" and "rewinding", wlriclr will be described in greater detail below.
7'he channel guide data source 109 provides periodic updates to the local channel guide database 103. The channel guide data source 109 provides program titles, start times, enc) tirncs, channel information and other criteria (such as ratings, descriptions of shows, n.rmes of actors, producers, directors, awards and rating information) regarding channel programming. Channel guide data sources are available commercially from 'I'VGuideT"', TV
Data, and Tribune media. The channel guide source may be accessed periodically to obtain changes and additions over any of a number of communication mediums. For example, the channel guide source may be accessed telephonically by a modern connection to a server or by receiving broadcasted updates and changes from a source such as satellite or terrestial VBI, national pager network or the Internet. 1n other embodiments, the channel guide source may be obtained periodically such as by subscription and received on a recording medium such as a disk through the mail or other source.
The video input source 106 may be any of a number of sourcea including cable, over-tlrc-air broadcast and satellite. 1n certain embodiments, multiple video input sources may he utili~~d. The video output source 107 is typically coupled with a display device such as a tclc:viaic~n but may also be coupled with another video data recorder.
The video compressor/decompressor 112 provides for compressing and d~:coroprcssing the video signal. Any commercially available compression technology may he utilii.cd including by way of example MPEG and MPEG I1.
1n alternative embodiments, the data may be received in a compressed format.
In such an ernbodiment, the compressor may not be utilized or even required and the dc:compressor may only be utili2ed to decornpreSS the compressed signals.
Temporal movement throueh the media Importantly, the disclosed embodiment provides certain user interface features. For rxamplc, in the disclosed embodiment it is possible to fast forward and rewind through recorded programming.
In one embodiment, the user may increase the rate of fast forwarding and/or rewinding by continuing to depress the fast forward and/or rewind button for a period of time. For example, if the button is pressed instantaneously, the system may fast forward or rewind at one speed and the speed may continuously increase the longer the button is depressed. This feature is described in connection with Figure ? which illustrates initia115~
that the medium is playing at a first temporal location, block 201. The user selects a temporal movement function (e.g., the fast forward or rewind button on the remote control), block 202.
Responsive to selection of the temporal movement function, rate of playback of the medium increased to a first rate if the temporal movement function is selected for a first period of time and at a second rate if the temporal movement function is selected for a second period of time, block 203.
In addition, the described embodiment provides an instant replay function. The user may depress the instant replay button and the system will automatically "rewind"
(move the point of viewing of the programming back in time, e.g., back temporally) a predetermined amount (e.g. 5 seconds) in the programming.
The described embodiment also provides a function for quickly advancing a predetermined temporal amount forward (e.g. 30 seconds). In certain embodiments, the predetermined temporal amount to move forward is chosen based on the length of a typical commercial allowing the user to quickly skip through commercials.
Figure 3 illustrates an overall flow diagram of a method of moving a predetermined temporal distance, based on user activation of function. The user function may be activated, for example, by the user depressing a button on a remote control device. As is illustrated by Figure 3, initially, the medium (which is illustrated in the figure as being video but in alternative embodiments may be audio or any other type of medium or media) is playing a first temporal location, block 301. The user selects a temporal movement function, block 302.
As was just discussed, the temporal movement may be either a predetermined distance forward or a predetermined distance backward. Responsive to the user selecting the temporal movement function, the play resumes at a second position temporally forward from or temporally backward from the first position.
g In both the case of moving temporally forward and temporally backward, the predetermined period of time may be set by the manufacturer of the device or may be user settable.
In an alternative embodiment, the movement backward or forward may be based on scene change analysis. For example, the "instant replay" function may skip back to the immediately preceding scene based on analysis of video frames and attempting to look for a scene change.
It is understood that the present invention may be used with different types of media and is not restricted to one type of medium.
Thus, what has been disclosed is an improved video data recorder.
