Abstract

A method and music video recorder (100) for recording music video clips receives announcements (210) concerning music videos to be broadcast over one or more audiovideo broadcast channels, where each announcement includes information regarding an associated music video and an indication of a time period when the music video is being broadcast. One or more selection criteria is provided (220) for selecting which of the music videos should be recorded. The information regarding each announced music video is compared (230) to the selection criteria for determining whether the announced music video should be recorded. When the information regarding one of the announced music videos matches the selection criteria, the associated music video is recorded (240) on a storage device (130) for future playback. An access rights limitation is applied to the stored music video.

Description

MUSIC VIDEO CLIP RECORDER AND METHOD OF RECORDING MUSIC VIDEOS
This invention pertains to a recording device and a method of recording audiovideo content, and more particularly to a music video clip recording device and method of recording music video clips.
As the capacity of cable television and satellite television systems continues to expand, there continues to be a growth in the number of broadcast television channels that broadcasts music videos. In some cases, a cable of satellite television signal may include dozens of channels dedicated for broadcasting music video clips. For a consumer's standpoint, the expansion of choices is good, but in its current form there are some limitations.
Typically, a consumer may have to view or listen to a channel for a long period of time before receiving a particular music video clip that she enjoys. Furthermore, a consumer can typically only monitor one, or at most two, television channels at any given time. This means there is a very high probability that a consumer will miss the broadcast of a music video clip of interest. In other words, this broadcast experience is not very direct and is totally non-interactive for the consumer. Furthermore, when a consumer does manage to record a music video clip from a broadcast signal for free and has unlimited access rights to play back the clip, to record it on a second device, etc., then the incentive for the consumer to actually purchase a copy of the clip is reduced. At the same time, perhaps the best opportunity for a copyright holder to successfully market a music video clip for sale to a consumer is while the consumer is actually enjoying watching or listening to the clip.
Accordingly, it would be desirable to provide a method and apparatus for recording music videos which has increased user interactivity. It would also be desirable to provide such a method and apparatus which can identify and capture music videos of interest to a consumer from multiple broadcast channels. It would be further desirable to provide a method and apparatus for recording music videos which applies access rights limitations to the music videos to preserve the rights of the copyright holders, and which allows a user to conduct transactions for acquiring additional rights for the music videos. The present invention is directed to addressing one or more of the preceding concerns. In one aspect of the invention, a method of recording music video clips comprises: receiving announcements concerning music videos to be broadcast over one or more audiovideo broadcast channels, each announcement including information regarding an associated music video and an indication of a time period when the music video is being broadcast; providing one or more selection criteria for selecting which of the music videos should be recorded; comparing the information regarding each announced music video to the selection criteria for determining whether the announced music video should be recorded; and when the information regarding one of the announced music videos satisfies the selection criteria, recording the associated music video on a storage device for future playback and applying thereto an access rights limitation for the associated music video.
In another aspect of the invention, a music video recorder comprises: a receiver adapted to receive announcements concerning music videos to be broadcast over one or more audiovideo broadcast channels, each announcement including information regarding an associated music video and an indication of a time period when the music video is being broadcast; a content selector adapted to receive and store one or more selection criteria for selecting which of the broadcast music videos should be recorded, to compare the information regarding the announced music videos to the selection criteria, and in response to the information satisfying the selection criteria, selecting at least one music video to be recorded; and a storage device adapted to record the selected music video for future playback and to apply thereto an access rights limitation for the associated music video. Further and other aspects will become evident from the description to follow.
FIG. 1 is a functional block diagram of a music video recorder; FIG. 2 is a flowchart illustrating on embodiment of a method of selecting and storing music videos broadcast over one or more audiovideo broadcast channels.
The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which preferred embodiments of the invention are shown. This invention may, however, be embodied in different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided as teaching examples of the invention.
FIG. 1 is a functional block diagram of a music video recorder 100. As will be appreciated by those skilled in the art, the various "parts" shown in FIG. 1 may be physically implemented using a software-controlled microprocessor, hard- wired logic circuits, or a combination thereof. Also, while the parts are functionally segregated in FIG. 1 for explanation purposes, they may be combined in any physical implementation. Music video recorder 100 includes a receiver 110, a content selector 120, a storage device 130, a recording controller 140, an interface 150, a music video player 160, and a backchannel communication unit 170.
Receiver 110 is adapted to be connected to an output of a broadcast receiver (not shown) that receives one or more audiovisual broadcast channels, such as a terrestrial digital television receiver, cable television receiver, satellite television receiver, including a so-called "set-top box," etc.
The broadcast receiver receives one or more audiovideo channels which broadcast music video clips. In general, broadcast receiver receives a composite signal from a single transmitter (e.g., cable headend; satellite downlink) that includes a plurality of audiovideo channels which broadcast music video clips, and the signal includes announcements of music video signals which are scheduled to be broadcast. In this case, the announcements for the music videos broadcast on all of the audiovideo channels may be broadcast on a single channel or data stream of the composite signal, for example as a unified schedule of music video broadcasts. However, alternatively, the broadcast receiver may receive audiovideo channels from a plurality of separate, remotely-located transmitters, for example in the case of a terrestrial broadcast receiver. In that case, the announcements for each audiovideo channel may be broadcast separately. Beneficially, the announcements are made far in advance (e.g., hours or days before) of when the music video is scheduled to be broadcast. However, optionally, an announcement may be made immediately preceding the commencement of broadcasting a music video. Beneficially, each announcement includes information regarding an associated music video, and an indication of a time period (e.g., a start time and a stop time) when the music video is being broadcast. The announcement may include a song title, the name of the performing artist, an album name, the song's author(s), the year the music video was produced, the director of the music video, etc. The announcement may also include information regarding one or more access rights limitations that must be applied to a particular music video if it is recorded.
The announcement for a music video may be associated with (e.g., transmitted as side channel information for) the particular audiovideo channel in which the music video is scheduled to be broadcast. That is, each different audiovideo channel may have its own announcements for the music videos being broadcast on that channel. Alternatively, the announcements for all of the audiovideo channels may be combined into a unified schedule, which may be associated with one of the audiovideo channels, or even a dedicated "music video program guide" channel. In that case, the announcement should include an ID identifying the channel on which each music video is scheduled to be broadcast.
Receiver 110 receives the one or more audiovideo channels from the broadcast receiver. Beneficially, receiver 110 may also be adapted to receive any side channel information, such as program ID codes, program descriptions, program guide information, etc. that is received by the broadcast receiver. Beneficially, receiver 110 is adapted to receive from the broadcast receiver the announcements concerning music videos to be broadcast over one or more of the audiovideo broadcast channels. Receiver 110 operates under the control of content selector 120. Beneficially, receiver 110 can instruct the communications receiver to tune to a particular broadcast channel.
Content selector 120 includes a user interface, one or more timers, and optionally one or more databases.
Content selector 120 may include a music video database of all music videos whose broadcast over any of the audiovideo channels of the broadcast receiver has already been announced and whose announcement has been received by receiver 110. That is, in that case, whenever a music video announcement is received by receiver 110, information regarding an associated music video, including an indication of a time period when the music video is being broadcast, is stored in the music video database. Beneficially, the music video database also stores an ID identifying the channel on which each music video is scheduled to be broadcast, which may be received in the announcement of the music video, or may be determined by receiver 110 and communicated to content selector 120.
Content selector 120 may also include a selection criteria database including criteria provided by a user for selecting music videos to be recorded, as discussed in more detail below. The user interface allows a user to enter one or more selection criteria for selecting a music video to be recorded. The user interface may be as simple as a button on a remote control unit which the user depresses whenever she hears a music video she wants to record, or whenever she sees an announcement on a display screen associated with the broadcast receiver that a particular music video will be broadcast at a future time. Additionally, the user interface may include a graphical component displayed on the display screen, for example providing a table of music video titles that are scheduled to be broadcast. The user may navigate the user interface using one or more arrow keys, a mouse, a touchwheel, a keyboard, or other means for navigating a graphical user interface.
Through the user interface, a user may: enter an artist, album, or song title of a music video clip she wants to record; enter keywords for automated recording based on keyword match; select a music video clip from a displayed schedule of music video clips scheduled for broadcast; select a music video that is currently playing to be recorded in the future; select a music video clip directly from a database of music video clips scheduled for broadcast, etc.
Content selector 120 compares the information regarding the announced music videos in the music video database to the selection criteria in the selection criteria databases, and when the information for any of the music videos satisfies any of the selection criteria, then content selector 120 schedules the music video for recording. In one embodiment, content selector 120 sets a timer to tune to the channel on which the associated music video is scheduled to be broadcast before the scheduled start time.
Optionally, content selector 120 may employ artificial intelligence to automatically select music videos to be recorded by analyzing: one or more characteristics of the selection criteria provided by the user; the information associated with other music videos selected by the user; etc.
Content selector 120 may also include a selected music video database including information regarding the music videos that have been selected and scheduled for recording. Optionally, assuming that it has sufficient processing power and bandwidth, then content selector 120 may not include a music video database, but instead may receive announcements from receiver 110 and compare the announcements "on-the-fly" with the selection criteria to determine whether or not the selection criteria is satisfied (whether there is a match). The various databases of content selector 120 are beneficially updated automatically to purge information regarding music videos that have already been broadcast and/or recorded. When the time for recording a selected music video arrives (e.g., a timer for the selected music video expires), then beneficially receiver 110 instructs the broadcast receiver to tune to the particular broadcast channel where the selected music video is about to be broadcast. When receiver 110 begins to receive the music video, then content selector 120 or receiver 110 informs recording controller 140.
At that time, recording controller 140 starts recording onto storage device 130 the input channel stream of the selected music video that is provided to receiver 110 from the broadcast receiver. When the music video has one or more access rights limitations, recording controller 140 also applies the access rights limitation(s) to the recorded music video. For example, an access rights limitation may specify a maximum number of times, N, that the recorded music video may be played back before additional access rights for the associated music video must be acquired. In another case, an access rights limitation may specify an expiration time (e.g., five days) after which the music video may no longer be played. Many such access rights limitations are possible. The access rights limitation(s) may be retrieved from the music video database or from the selected music video database, when the access rights limitation(s) are included in the announcement for the music video. Alternatively, the access rights limitation(s) may be broadcast and received at a same time together with the music video. In another embodiment, music video recorder 100 may be provided with one or more default access rights limitation(s) that are stored in a memory device of music video recorder 100.
Interface 150 functions as a transfer port that allows music video recorder 100 to transfer a stored music video onto a peripheral device, such as a portable storage device, music player, or music video player. So long as there is no access rights limitation preventing it, a user may download a portion (e.g., the audio portion only) or all of a recorded music video from storage device 130 until the peripheral device through the interface 150. The peripheral device may then be detached from the interface 150 and taken away by a user.
Beneficially, the peripheral device may have an ID code that is detected by music video recorder 100 through interface 150. For example, music video recorder 100 may be associated with one or more approved peripheral devices. In that case, music video recorder 100 may be configured to only transfer a portion or all of a recorded music video onto an approved peripheral device, and may not transfer any portion of a recorded music video to any other (unapproved) peripheral device. Furthermore, music video recorder 100 applies all appropriate access rights limitations to the music video when it is transferred to the approved peripheral device. For example, one access rights limitation may prevent the music video from being transferred from the peripheral device to any other device.
Music video player 160 allows a user to play back music videos recorded on storage device 130. Beneficially, music video player 160 includes a user interface for allowing a user to select a desired music video for playback among a plurality of music videos that may be stored on storage device 130. The user interface may also allow a user to select one or more music videos to be erased from storage device 130.
Music video player 160 also enforces any access rights limitations for the music video. For example, where an access rights limitation specifies a maximum number of times, N, that the recorded music video may be played back before additional access rights for the associated music video must be acquired, then music video player 160 maintains a record of the number of times that it has played the music video and when the maximum number of playbacks has been reached, music video player 160 prevents the music video from being played back any further until and unless additional access rights are acquired. In another example, where an access rights limitation specifies an expiration time for the music video, music video player 160 may prevent the music video from being played any longer after the expiration period has been reached. Also, depending on the access rights limitation, music video player 160 may instruct recording controller 140 to delete a music video from storage device 130 once an access rights limitation has been met.
Beneficially, music video player 160 may inform the user through its user interface (e.g., by displaying a message on a display screen associated with the broadcast receiver) when an access rights limitation has been reached. Furthermore, music video recorder 100 may present the user with an option for acquiring additional access rights for the music video. For example, music video recorder 100 may enable a user to purchase access rights for unlimited playback of the music video. In another example, music video recorder 100 may enable a user to purchase access rights for downloading the music video onto a peripheral device via interface 150.
In that case, backchannel communication unit 170 provides a means for a user to acquire additional access rights for a music video. Beneficially backchannel communication unit 170 provides a two-way communication path with one or more access rights controllers. Backchannel communication unit 170 may comprise a telephone connection, a two-way satellite or cable communication transceiver, or an Internet communication port. Typically, the access rights controller(s) are located remote from music video recorder 100.
There may be a single access rights controller for all of the music videos received over the broadcast audiovideo channels by the broadcast receiver, or there may be a plurality of access rights controllers associated with different music videos. In that case, beneficially the information included in the announcement for the music video includes information (e.g., an ID code) identifying a corresponding access rights controller for acquiring additional access rights for the music video. That information is then captured and stored by music video recorder 100, and retrieved when a user indicates a desire to acquire additional access rights.
In response to a user's request (e.g., via the user interface for music video player 160) to acquire additional access rights for a music video, backchannel communication unit 170 communicates with the appropriate access rights controller to obtain the desired access rights. The transaction may be accomplished in a variety of ways. In one simple example, a user's credit card number is communicated via a secure connection to the access rights controller, and a digital access rights key is communicated from the access rights controller to music video recorder 100. Alternatively, a unique ID associated with music video recorder 100, or a user thereof, may be communicated to the access rights controller. In that case, the access rights controller may use the unique ID to retrieve an appropriate credit card number from a database stored at the access rights controller. In another alternative, the unique ID may be used to make a record of the user's purchase, and the record is communicated to the user's cable or satellite television service provider. In that case, the cable or satellite television service provider may include a charge for the access rights purchase with the user's next bill. Many alternative arrangements are possible. Once the additional access rights for a music video have been acquired, an indication of those access rights is provided to music video recorder 100. For example a digital access rights key may be transmitted (e.g., from the access rights controller) to music video recorder 100. In response to a user acquiring additional access rights for a particular music video, music video recorder 100 removes any previous access rights limitation(s) for the associated music video that are no longer valid, and applies to the music video any additional access rights limitation(s) that may be included in the additional access rights acquired by the user. Although music video recorder 100 is described above as a standalone device, in another embodiment music video recorder 100 could be integrated into a broadcast receiver, such as a cable television receiver, satellite television receiver, including a set-top box. Alternatively, music video recorder 100 may be integrated into a general purpose personal computer running a general purpose operating system such as MICROSOFT® WINDOWS®, LINUX, etc.
FIG. 2 illustrates one embodiment of a method of selecting and storing music videos broadcast over one or more audio video broadcast channels.
In a step 210, announcements are received concerning music videos to be broadcast over one or more audiovideo broadcast channels. Each announcement includes information regarding an associated music video, and an indication of a time period when the music video is being broadcast.
In a step 220, one or more selection criteria are provided for selecting which of the music videos should be recorded. In a step 230, the information regarding each announced music video is compared to the selection criteria for determining whether the announced music video should be recorded. In one embodiment information from the announcements is stored in a database, including the time period when each music video is being broadcast and an ID identifying a channel on which each music video is being broadcast. In that case, the information in the database regarding each announced music video is compared to the selection criteria for determining whether the announced music video should be recorded.
In a step 240, when the information regarding one of the announced music videos satisfies the selection criteria, then the associated music video is recorded onto a storage device for future playback. Where any access rights limitations have been received for a music video, those access rights limitations are applied to the music video when it is stored onto the storage device. In one embodiment, when the information regarding one of the announced music videos satisfies the selection criteria, a timer is set to tune to the channel on which the associated music video is broadcast before the start time when the associated music video is scheduled to be broadcast. As described above, a method and apparatus for recording music video clips has increased user interactivity. The method and apparatus can identify and capture music videos of interest to a consumer from multiple broadcast channels. All appropriate access rights limitations are applied to the stored music videos to preserve the rights of the copyright holders. Furthermore, a user is enabled to conduct a transaction for acquiring additional rights, typically for a fee.
While preferred embodiments are disclosed herein, many variations are possible which remain within the concept and scope of the invention. Such variations would become clear to one of ordinary skill in the art after inspection of the specification, drawings and claims herein. The invention therefore is not to be restricted except within the spirit and scope of the appended claims.
