Description:
CROSS-REFERENCE TO RELATED APPLICATIONS 
     This application is a continuation of U.S. patent application Ser. No. 16/903,137, filed Jun. 16, 2020, which is a continuation of U.S. patent application Ser. No. 14/994,783 (now U.S. Patent No. 10,726,871), filed Jan. 13, 2016, which is a continuation of U.S. patent application Ser. No. 14/467,785 (now U.S. Pat. No. 9,269,396), filed Aug. 25, 2014, which is a continuation of U.S. patent application Ser. No. 13/193,710 (now U.S. Pat. No. 8,849,948), filed Jul. 29, 2011. The disclosures of each application are hereby incorporated by reference herein in their entireties. 
    
    
     BACKGROUND 
     Users are consuming a variety of content through a variety of platforms. Television, movies, music, and the like are consumed daily through computers, televisions, smartphones, and a myriad of other devices. Users are presented with unprecedented selections of what content they want to consume, when they want to consume the content, and where they want to consume the content. Unfortunately, users are limited in how to consume content. Users are restricted to consuming content at a predefined “normal” playback speed that may not be to the user&#39;s liking or within the user&#39;s time constraints. While manipulating playback speed with “fast forward” and “rewind” functions is known, users have no control over just how fast or slow playback occurs. Similarly, users are unable to dynamically adjust playback speeds for different types of content or segments within content. The present disclosure identifies and addresses a need for a system to enable users to enjoyably consume content at an automatically and dynamically adjusted speed (e.g., faster or slower than normal playback speed) without constant manipulation of “fast forward” or “rewind” functions. 
     SUMMARY 
     It is to be understood that both the following general description and the following detailed description are exemplary and explanatory only and are not restrictive, as claimed. Provided are methods and systems for variable speed playback, comprising receiving content comprising a first playback speed, determining a second playback speed for at least a portion of the content based on a playback factor, associating the second playback speed with the portion of the content, and providing at least the portion of the content at the second playback speed to a display device. 
     Additional advantages will be set forth in part in the description which follows or may be learned by practice. The advantages will be realized and attained by means of the elements and combinations discussed in the disclosure and particularly pointed out in the appended claims.

       FIG.  1    illustrates various aspects of an exemplary system in which the present methods and systems can operate. The present disclosure relates to variable speed playback of content. Those skilled in the art will appreciate that the present methods may be used in systems that employ both digital and analog equipment. One skilled in the art will appreciate that provided herein is a functional description and that the respective functions can be performed by software, hardware, or a combination of software and hardware. 
     The system  100  can comprise a central location  101  (e.g., a headend), which can receive content (e.g., data, input programming, and the like) from multiple sources. The central location  101  can combine the content from the various sources and can distribute the content to user (e.g., subscriber) locations (e.g., location  119 ) via distribution system  116 . 
     In an aspect, the central location  101  can receive content from a variety of sources  102   a ,  102   b ,  102   c . The content can be transmitted from the source to the central location  101  via a variety of transmission paths, including wireless (e.g. satellite paths  103   a ,  103   b ) and terrestrial path  104 . The central location  101  can also receive content from a direct feed source  106  via a direct line  105 . Other input sources can comprise capture devices such as a video camera  109  or a server  110 . The signals provided by the content sources can include a single content item or a multiplex that includes several content items. 
     The central location  101  can comprise one or a plurality of receivers  111   a ,  111   b ,  111   c ,  111   d  that are each associated with an input source. For example, MPEG encoders such as encoder  112 , are included for encoding local content or a video camera  109  feed. A switch  113  can provide access to server  110 , which can be a Pay-Per-View server, a data server, an internet router, a network system, a phone system, and the like. Some signals may require additional processing, such as signal multiplexing, prior to being modulated. Such multiplexing can be performed by multiplexer (mux)  114 . 
     The central location  101  can comprise one or a plurality of modulators,  115   a ,  115   b ,  115   c , and  115   d , for interfacing to the distribution system  116 . The modulators can convert the received content into a modulated output signal suitable for transmission over the distribution system  116 . The output signals from the modulators can be combined, using equipment such as a combiner  117 , for input into the distribution system  116 . 
     A control system  118  can permit a system operator to control and monitor the functions and performance of system  100 . The control system  118  can interface, monitor, and/or control a variety of functions, including, but not limited to, the channel lineup for the television system, billing for each user, conditional access for content distributed to users, and the like. Control system  118  can provide input to the modulators for setting operating parameters, such as system specific MPEG table packet organization or conditional access information. The control system  118  can be located at central location  101  or at a remote location. 
     The distribution system  116  can distribute signals from the central location  101  to user locations, such as user location  119 . The distribution system  116  can be an optical fiber network, a coaxial cable network, a hybrid fiber-coaxial network, a wireless network, a satellite system, a direct broadcast system, or any combination thereof. There can be a multitude of user locations connected to distribution system  116 . At user location  119 , a decoder  120 , such as a gateway or home communications terminal (HCT) can decode, if needed, the signals for display on a display device, such as on a television set (TV)  121  or a computer monitor. Those skilled in the art will appreciate that the signal can be decoded in a variety of equipment, including an HCT, a computer, a TV, a monitor, or satellite dish. In an exemplary aspect, the methods and systems disclosed can be located within, or performed on, one or more HCT&#39;s  120 , TV&#39;s  121 , central locations  101 , DVR&#39;s, home theater PC&#39;s, and the like. 
     In an aspect, user location  119  is not fixed. By way of example, a user can receive content from the distribution system  116  on a mobile device such as a laptop computer, PDA, smartphone, GPS, vehicle entertainment system, portable media player, and the like. 
     In an aspect, the methods and systems can utilize digital audio/video compression such as MPEG, or any other type of compression. The Moving Pictures Experts Group (MPEG) was established by the International Standards Organization (ISO) for the purpose of creating standards for digital audio/video compression. The MPEG experts created the MPEG-1 and MPEG-2 standards, with the MPEG-1 standard being a subset of the MPEG-2 standard. The combined MPEG-1, MPEG-2, and MPEG-4 standards are hereinafter referred to as MPEG. In an MPEG encoded transmission, content and other data are transmitted in packets, which collectively make up a transport stream. Additional information regarding transport stream packets, the composition of the transport stream, types of MPEG tables, and other aspects of the MPEG standards are described below. In an exemplary embodiment, the present methods and systems can employ transmission of MPEG packets. However, the present methods and systems are not so limited, and can be implemented using other types of transmission and data. 
     The output of a single MPEG audio and/or video coder is called a transport stream comprised of one or more elementary streams. An elementary stream is an endless near real-time signal. For convenience, the elementary stream may be broken into data blocks of manageable size, forming a packetized elementary stream (PES). These data blocks need header information to identify the start of the packets and must include time stamps because packetizing disrupts the time axis. For transmission and digital broadcasting, for example, several programs and their associated PESs can be multiplexed into a multi program transport stream. A multi program transport stream has a program clock reference (PCR) mechanism that allows transmission of multiple clocks, one of which is selected and regenerated at the decoder. 
     A multi program transport stream is more than just a multiplex of audio and video PESs. In addition to the compressed audio, video and data, a transport stream includes metadata describing the bit stream. This includes the program association table (PAT) that lists every program in the multi program transport stream. Each entry in the PAT points to a program map table (PMT) that lists the elementary streams making up each program. Some programs will be unencrypted, but some programs may be subject to conditional access (encryption) and this information is also carried in the metadata. The transport stream can be comprised of fixed-size data packets, for example, each containing 188 bytes. Each packet can carry a program identifier code (PID). Packets in the same elementary stream can all have the same PID, so that the decoder (or a demultiplexer) can select the elementary stream(s) it wants and reject the remainder. Packet continuity counts ensure that every packet that is needed to decode a stream is received. A synchronization system can be used so that decoders can correctly identify the beginning of each packet and deserialize the bit stream into words. 
     A content item, such as a program, can be a group of one or more PIDs that are related to each other. For instance, a multi program transport stream used in digital television might contain three programs to represent three television channels. Suppose each channel consists of one video stream, one or two audio streams, and any necessary metadata. A receiver wishing to tune to a particular “channel” merely has to decode the payload of the PIDs associated with its program. It can discard the contents of all other PIDs. 
     The multi program transport stream carries many different programs and each may use a different compression factor and a bit rate that can change dynamically even though the overall bit rate stays constant. This behavior is called statistical multiplexing and it allows a program that is handling difficult material to borrow bandwidth from a program handling easy material. Each video PES can have a different number of audio and data PESs associated with it. Despite this flexibility, a decoder must be able to change from one program to the next and correctly select the appropriate audio and data channels. Some of the programs can be protected so that they can only be viewed by those who have paid a subscription or fee. The transport stream can comprise Conditional Access (CA) information to administer this protection. The transport stream can comprise Program Specific Information (PSI) to handle these tasks. 
     In an exemplary aspect, the methods and systems can be implemented on a computer  201  as illustrated in  FIG.  2    and described below. By way of example, server  110  of  FIG.  1    can be a computer as illustrated in  FIG.  2   . Similarly, the methods and systems disclosed can utilize one or more computers to perform one or more functions in one or more locations.  FIG.  2    is a block diagram illustrating an exemplary operating environment for performing the disclosed methods. This exemplary operating environment is only an example of an operating environment and is not intended to suggest any limitation as to the scope of use or functionality of operating environment architecture. Neither should the operating environment be interpreted as having any dependency or requirement relating to any one or combination of components illustrated in the exemplary operating environment. 
     The present methods and systems can be operational with numerous other general purpose or special purpose computing system environments or configurations. Examples of well known computing systems, environments, and/or configurations that can be suitable for use with the systems and methods comprise, but are not limited to, personal computers, server computers, laptop devices, and multiprocessor systems. Additional examples comprise set top boxes, programmable consumer electronics, network PCs, minicomputers, mainframe computers, distributed computing environments that comprise any of the above systems or devices, and the like. 
     The processing of the disclosed methods and systems can be performed by software components. The disclosed systems and methods can be described in the general context of computer-executable instructions, such as program modules, being executed by one or more computers or other devices. Generally, program modules comprise computer code, routines, programs, objects, components, data structures, etc. that perform particular tasks or implement particular abstract data types. The disclosed methods can also be practiced in grid-based and distributed computing environments where tasks are performed by remote processing devices that are linked through a communications network. In a distributed computing environment, program modules can be located in both local and remote computer storage media including memory storage devices. 
     Further, one skilled in the art will appreciate that the systems and methods disclosed herein can be implemented via a general-purpose computing device in the form of a computer  201 . The components of the computer  201  can comprise, but are not limited to, one or more processors or processing units  203 , a system memory  212 , and a system bus  213  that couples various system components including the processor  203  to the system memory  212 . In the case of multiple processing units  203 , the system can utilize parallel computing. 
     The system bus  213  represents one or more of several possible types of bus structures, including a memory bus or memory controller, a peripheral bus, an accelerated graphics port, and a processor or local bus using any of a variety of bus architectures. By way of example, such architectures can comprise an Industry Standard Architecture (ISA) bus, a Micro Channel Architecture (MCA) bus, an Enhanced ISA 
     (EISA) bus, a Video Electronics Standards Association (VESA) local bus, an Accelerated Graphics Port (AGP) bus, a Peripheral Component Interconnects (PCI), a PCI-Express bus, a Personal Computer Memory Card Industry Association (PCMCIA), Universal Serial Bus (USB), and the like. The bus  213 , and all buses specified in this description can also be implemented over a wired or wireless network connection and each of the subsystems, including the processor  203 , a mass storage device  204 , an operating system  205 , variable playback software  206 , playback data  207 , a network adapter  208 , system memory  212 , an Input/Output Interface  210 , a display adapter  209 , a display device  211 , and a human machine interface  202 , can be contained within one or more remote computing devices  214   a,b,c  at physically separate locations, connected through buses of this form, in effect implementing a fully distributed system. 
     The computer  201  typically comprises a variety of computer readable media. Exemplary readable media can be any available media that is accessible by the computer  201  and comprises, for example and not meant to be limiting, both volatile and non-volatile media, removable and non-removable media. The system memory  212  comprises computer readable media in the form of volatile memory, such as random access memory (RAM), and/or non-volatile memory, such as read only memory (ROM). The system memory  212  typically contains data such as playback data  207  and/or program modules such as operating system  205  and variable playback software  206  that are immediately accessible to and/or are presently operated on by the processing unit  203 . 
     In another aspect, the computer  201  can also comprise other removable/non-removable, volatile/non-volatile computer storage media. By way of example,  FIG.  2    illustrates a mass storage device  204  which can provide non-volatile storage of computer code, computer readable instructions, data structures, program modules, and other data for the computer  201 . For example and not meant to be limiting, a mass storage device  204  can be a hard disk, a removable magnetic disk, a removable optical disk, magnetic cassettes or other magnetic storage devices, flash memory cards, CD-ROM, digital versatile disks (DVD) or other optical storage, random access memories (RAM), read only memories (ROM), electrically erasable programmable read-only memory (EEPROM), and the like. 
     Optionally, any number of program modules can be stored on the mass storage device  204 , including by way of example, an operating system  205  and variable playback software  206 . Each of the operating system  205  and variable playback software  206  (or some combination thereof) can comprise elements of the content and the variable playback software  206 . In an aspect, variable playback software  206  can comprise standalone software and/or software integrated into existing content players, for example, Windows® Media Player, Realplayer®, iTunes®, and the like. Playback data  207  can also be stored on the mass storage device  204 . Playback data  207  can be stored in any of one or more databases known in the art. Examples of such databases comprise, DB2®, Microsoft® Access, Microsoft® SQL Server, Oracle®, mySQL, PostgreSQL, and the like. The databases can be centralized or distributed across multiple systems. 
     In another aspect, the user can enter commands and information into the computer  201  via an input device (not shown). Examples of such input devices comprise, but are not limited to, a keyboard, pointing device (e.g., a “mouse”), a microphone, a joystick, a scanner, tactile input devices such as gloves, and other body coverings, and the like. These and other input devices can be connected to the processing unit  203  via a human machine interface  202  that is coupled to the system bus  213 , but can be connected by other interface and bus structures, such as a parallel port, game port, an IEEE 1394 Port (also known as a Firewire port), a serial port, or a universal serial bus (USB). 
     In yet another aspect, a display device  211  can also be connected to the system bus  213  via an interface, such as a display adapter  209 . It is contemplated that the computer  201  can have more than one display adapter  209  and the computer  201  can have more than one display device  211 . For example, a display device can be a monitor, an LCD (Liquid Crystal Display), or a projector. In addition to the display device  211 , other output peripheral devices can comprise components such as speakers (not shown) and a printer (not shown) which can be connected to the computer  201  via Input/Output Interface  210 . Any step and/or result of the methods can be output in any form to an output device. Such output can be any form of visual representation, including, but not limited to, textual, graphical, animation, audio, tactile, and the like. The display  211  and computer  201  can be part of one device, or separate devices. 
     The computer  201  can operate in a networked environment using logical connections to one or more remote computing devices  214   a,b,c . By way of example, a remote computing device can be a personal computer, portable computer, smartphone, a server, a router, a network computer, a peer device or other common network node, and so on. Logical connections between the computer  201  and a remote computing device  214   a,b,c  can be made via a network  215 , such as a local area network (LAN) and/or a general wide area network (WAN). Such network connections can be through a network adapter  208 . A network adapter  208  can be implemented in both wired and wireless environments. Such networking environments are conventional and commonplace in dwellings, offices, enterprise-wide computer networks, intranets, and the Internet. 
     For purposes of illustration, application programs and other executable program components such as the operating system  205  are illustrated herein as discrete blocks, although it is recognized that such programs and components reside at various times in different storage components of the computing device  201 , and are executed by the data processor(s) of the computer. An implementation of variable playback software  206  can be stored on or transmitted across some form of computer readable media. Any of the disclosed methods can be performed by computer readable instructions embodied on computer readable media. Computer readable media can be any available media that can be accessed by a computer. By way of example and not meant to be limiting, computer readable media can comprise “computer storage media” and “communications media.” “Computer storage media” comprise volatile and non-volatile, removable and non-removable media implemented in any methods or technology for storage of information such as computer readable instructions, data structures, program modules, or other data. Exemplary computer storage media comprises, but is not limited to, RAM, ROM, EEPROM, flash memory or other memory technology, CD-ROM, digital versatile disks (DVD) or other optical storage, magnetic cassettes, magnetic tape, magnetic disk storage or other magnetic storage devices, or any other medium which can be used to store the desired information and which can be accessed by a computer. 
     The methods and systems can employ Artificial Intelligence techniques such as machine learning and iterative learning. Examples of such techniques include, but are not limited to, expert systems, case based reasoning, Bayesian networks, behavior based AI, neural networks, fuzzy systems, evolutionary computation (e.g. genetic algorithms), swarm intelligence (e.g. ant algorithms), and hybrid intelligent systems (e.g., Expert inference rules generated through a neural network or production rules from statistical learning). 
     The present disclosure relates to systems that enable a user to consume content (or portions of content) at a slower or faster rate than “normal.” A variety of factors impact a user&#39;s desire to adjust content consumption rate. For example, a busy user may only have 20 minutes in which to watch a 30 minute television show. The user can, as described herein, view the content with certain portions sped up significantly in order to consume the content in the allotted time. Still other users may have a difficult time visually processing fast action scenes, and can thus consume that type of content at speeds slower than normal. Users can accomplish the adjusted consumption, not by manually pressing “fast forward” or “rewind” buttons (although such buttons/functions may be used in combination with the disclosure), but rather by relying on one or more playback factors as detailed herein. 
     The disclosure relates to adjusting the speed of content playback with, optionally, audio pitch shifting. One benefit of adjusting the speed of content playback is for users to consume content in less time than it would take to consume such content at a normal speed. In an aspect, the speed adjustment can be applied to portions of a program such that the playback time of the entire program is equivalent to the time it took to air normally. For example, some portions can be played at increased speed and other portions can be played at decreased speed. However, merely increasing the playback speed by a set amount would cause, at certain times, (depending on the talking speed of the speaker, amount of scene/camera cuts, or background noise, number of people speaking, and the like), difficulty in understanding what was said. The disclosure also relates to dynamic adjustment of playback speed. By dynamically adjusting playback speed based on, for example, content type, number of words/second spoken, and user preferences viewers can more easily understand the audio tracks while still maintaining a total play time similar to, or less than, what they would expect with a constant playback value. 
     Playback speed adjustment can be performed at various points in a content distribution system. For example, playback speed adjustment can be performed at a user&#39;s device, at the content creator&#39;s facility, at the content provider&#39;s facility, at a third party vendor facility, or any combination thereof. Similarly, preferences and profiles for playback speeds can be stored on content media, a user&#39;s device, at the content creator&#39;s facility, at the content provider&#39;s facility, at a third party vendor facility, or any combination thereof. In an aspect, preferences and playback profiles for content can be stored and downloaded through the Internet. 
     For example, during television shows prior to a commercial, there can be a “tease” for setting up interest in the next segment. Alternatively, there can be a lead out portion with a band playing music and the camera zooming out and panning the audience. A similar segment could occur after the commercial break. These are examples of segments that could be completely cut, but simply cutting out such segments might create too abrupt of a viewing experience. These segments can be sped up slightly or significantly, with a speed that is blended into the adjacent portions of the show&#39;s content. In another example, after a comedian tells a joke, the laughter can be sped up and then the playback speed slowed back down before the next joke (similar to a bell curve). These are merely examples of sections or portions of content that can have playback speeds adjusted. There are many other sections of content that can be sped up or slowed down. 
     In an aspect, illustrated in  FIG.  3   , provided are methods for variable speed playback, comprising receiving content comprising a first playback speed at  301 , determining a second playback speed for at least a portion of the content based on at least one playback factor at  302 , associating the second playback speed with the portion of the content at  303 ; and providing at least the portion of the content at the second playback speed to a display device at  304 . The methods can comprise determining a third playback speed for at least a second portion of the content based on the playback factor, or other playback factors, associating the third playback speed with the second portion of the content, and transitioning from providing at least the portion of the content at the second playback speed to providing at least the second portion of the content at the third playback speed to the display device. 
     In a further aspect, illustrated in  FIG.  4   , provided are methods for variable speed playback, comprising receiving content at  401 , determining whether the content, or a portion thereof, is a candidate for playback speed adjustment at  402 ; and adjusting the playback speed for the content, or the portion thereof, based on at least one playback factor  403 . In an aspect, steps  402  and  403  repeat throughout receipt and/or providing of the content in order to dynamically adjust playback speed of the content, or portions thereof, as the content is consumed. In a further aspect, a plurality of playback speeds can be determined. The methods can comprise transitioning from providing the content, or portions thereof, at a first playback speed to providing the content, or portions thereof, at a second playback speed to a display device. 
     In an aspect, playback speeds can be set greater than or less than the original playback speeds based at least one playback factor. Many situations can exist where playback speed can be adjusted higher or lower than normal to accommodate viewing preferences. For example, the second playback speed can be less than or equal to the first playback speed when multiple people are talking at the same time. By way of example, laugh track playback speed can be increased, static display of information, depending upon type, can be displayed at a decreased or increased playback speed, and the like. 
     Providing content to a display device can further comprise pitch shifted audio and/or an increased frame rate. To maintain the enjoyment of content, the methods and systems provided can automatically adjust not only video frame rate, but also the pitch of associated audio. This can prevent audio from sounding very high pitched in the event that playback speed is increased and can prevent audio from sounding very low pitched in the event that playback speed is decreased. 
     In an aspect, the playback factor can comprise one or more of a content type, a user preference profile, a third party playback profile, number of spoken syllables or words per unit of time, frequency of spoken words, comprehension difficulty level, or a rate of spoken words, for example. Content type can comprise, for example, a movie, a commercial, a television program, a music video, or audio only. The user preference profile can comprise a playback speed preferred by an end user and/or parameters selected by the user based on playback factors. For example, a user preference profile can comprise one or more of a slow motion, normal speed, fast, faster, fastest profile. Depending on the segment of content, the speed of playback can be sped up and slowed down according to user preferences. In an aspect, there is no requirement for a linear change between profiles. “Normal” speed can mean the content takes the same amount of time to consume as originally intended, but some portions of the content can be played at &lt;1.0× speed and some portions of the content can be played at &gt;1.0×, averaging out to 1.0× speed. User preferences can be associated with one or more segments of content (e.g., particular scenes), content type, and the like. For example, a user can specify a faster, slower, or normal playback speed for credit rolls, silent scenes, fight scenes, mature scenes, and the like. By way of further example, a user can specify a faster, slower, or normal playback speed for commercials, sitcoms, news reports, weather reports, infomercials, and the like. These user selectable profile speeds can be combined with metadata from a third party profile that describes sections of content to determine which sections are of higher/lower value. Combining the use of the user preference profile with third party profile allows more granular adjustable playback speeds. 
     The third party playback profile can comprise one or more playback speeds recommended by a third party. For example, the content can be tagged with markers designating the minimum, maximum, and/or average recommended playback speed as recommended by an expert or a friend, such as crowd sourced recommendations or recommendations from a director, editor, and the like. These recommendations can be compiled into a content playback profile. In an aspect, these speeds can be combined with user settings for a final playback value. For example, if a director tags a segment indicating a playback speed of 0.8× min, 1.1× avg, and 1.5× max, and a user has a “normal” playback speed selected (for example, selecting a 5 on a scale from 1 to 10 where 1 is the strongest preference for slow speeds and 10 is the strongest preference for fast speeds), the system can utilize the director&#39;s average recommended speed of 1.1. However, if the user has a playback speed setting of 8/10 selected, the system can utilize a playback speed closer to 1.5×, for example 1.4×. 
     In an aspect, illustrated in  FIG.  5   , provided are methods for variable speed playback, comprising receiving content comprising a content playback profile at  501 , determining a user preference profile at  502 , and providing the content to a display device by dynamically adjusting content playback speed based on the content playback profile and the user preference profile at  503 . 
     As provided herein, the content type can comprise, for example, a movie, a commercial, a television program, a music video, audio only content, and the like. The user preference profile can comprise a playback speed preferred by an end user. For example, the content playback profile can comprise a minimum playback speed, an average playback speed, a maximum playback speed, and the like. In an aspect, the content playback profile can comprise one or more playback speeds associated with segments of the content. By way of example, segments can comprise particular scenes, scene types, content types, and the like. 
     In a further aspect, illustrated in  FIG.  6   , provided are methods for variable speed playback, comprising transmitting content comprising a first playback speed at  601 , determining a second playback speed for at least a portion of the content based on at least one playback factor at  602 , associating the second playback speed with the portion of the content at  603 , and providing at least the portion of the content at the second playback speed to a display device at  604 . 
     As disclosed herein, the content type can comprise, for example, a movie, a commercial, a television program, a music video, audio only content, and the like. The at least one playback factor can comprise one or more of a content type, a user preference profile, a third party playback profile, a rate of spoken words, a number of spoken words, a number of spoken syllables, and the like. 
     The methods can further comprise setting the second playback speed greater than or less than the first playback speed based on the at least one playback factor. The methods can also further comprise displaying the content on the display device at the second playback speed. 
     In an aspect, provided are methods for translating a user friendly playback setting (e.g., a selection on a scale from 1 to 10) into an actual playback speed. For example, consider the user that selects a playback speed of 3 out of 10. The slowest user setting (1/10) and fastest user setting (10/10) can map to minimum and maximum playback speeds acquired from any source, for example, from the director. The settings in between (2/10-9/10) can be calculated depending on if the user setting was slower than average (5/10) or faster than average (5/10). For example with the user setting at less than average (3/10), a director tagged minimum of 0.8× (1/10), average of 1.1× (5/10), and maximum of 1.5× (10/10), then the playback speed can be determined according to the equation: Min speed+(user setting/(total user settings/2))*(avg playback speed−min playback). Accordingly, a user selection of 3/10 corresponds to a playback speed of 0.8+(3/(10/2))*(1.1−0.8)=0.98×. 
     In an aspect, playback speed can be adjusted to meet user defined rate of syllables or words per second. This playback factor can comprise a “normal” syllables or words per second that can be calculated from the content, for example a television show (an overall average). The number of words or syllables per second of specific timeframes can be calculated throughout the show or specific types of scenes throughout the show. In an aspect, this number would not be static throughout, but rather would vary during the course of the show. The number can be calculated from the timeframes when closed captions are displayed (minus the character tags and other descriptions of sounds). This number can be considered 1.0× playback syllables/words per second for that timeframe. 
     In an aspect, the rate of words spoken can be determined by analyzing closed caption data associated with the portion or the entire content to determine a number of spoken words or syllables per minute. Other time frame related rates can be utilized such as per second, per hour, and the like. In an aspect, some live events have delayed closed captions that can be known or detected, so the closed caption data would be shifted by a few seconds before determining playback speed. This does not present a problem since an increased playback speed can not be achieved while watching live content if transmitted at a linear speed. In an aspect, detection of delay can occur automatically by monitoring the audio frequency range of the human voice, and matching those sections of human voice to closed caption data. In another aspect, a speech to text translator can be used to translate voice (e.g., from a center audio channel or unique voice-only audio track) into text in order to determine one or more playback factors disclosed herein such as spoken word rate, syllable rate, and the like. 
       FIG.  7    illustrates an example dialog and air times in a piece of content. By way of example, to calculate baseline syllables or words per second, add half of the gap from the previous and following captions on each side of the subject captions (0.25+0.25), plus the timeframe where the subject captions are displayed (3.5), which equals 4.0 seconds. Then the words or syllables per second are calculated (20 words, 25 syllables), which is 5 words per second or 6.25 syllables a second. If the average syllables per second of the entire show is 7.1 syllables/second, and a user enters increased playback at 1.2× for the entire show, (for example: 7.1*1.2=8.52) then 8.52 syllables/second would be the increased playback speed. This same segment that took 4.0 seconds to playback at 1.0× speed would be increased based on this calculation: 25 (syllables)/8.52 (syllables/second)=2.934 seconds to playback (instead of 4.0 seconds). Similar calculations can be performed based on words per second. 
     In another aspect, overlays can be placed on screens to display information such as phone numbers. These overlays can be used as a playback factor. Overlays can be detected and those segments can have playback speeds slowed down (or sped up) or if enough resources exist that overlay can be “frozen” on screen for the amount of playback time expected at 1.0× speed. Overlays and other static information displayed during a program, such as phone numbers, can be considered more important. The region containing the overlay can be frozen to keep it on screen as long as it was expected to, even when playback is increased. Alternatively, the period during the overlays can be slowed down and treated as more important. 
     Associating the second and/or additional playback speed with the portion of the content can also comprise adding metadata to the content describing the second playback speed and the particular point within the content. The methods can further comprise displaying the content on the display device at the second and/or additional playback speeds. In an aspect, metadata can be added to “important” segments (voting results, jokes, etc.). The methods can weigh the segments based on how much time a segment should be or has been allocated in proportion to other segments during playback. For example, segments can be tagged at a recommended min/max/average playback speed for different segments, or the min/max/average can be considered to be its own metadata tagging method. Users can set a percentage of minimum, maximum, or average speed at which they want to view content. 
     In another aspect, crowd sourcing can be implemented to determine which segments of content most users fast forward through to help determine the most important segments. A content provider can capture feedback from users, for example, such as when/if the user changed between the “user profiles” option of increased playback. This can indicate that the user was not happy with the final weighted playback speed that was selected for them. Statistics can then be taken from all users as to which segments they watched at an increased rate of speed and find the segments which are statistically less important to most users and create a corresponding playback factor. 
     One or more aspects of determining playback speeds can be implemented in a single method. For example, for movies and highly watched content, metadata can be added (either one or all of methods: profiles/min, max, avg/important segments), but for less watched or some live content where preproduction might not be possible, a client based approach can be used (crowd sourcing/closed caption gathering). 
     In an aspect, a piece of content can have a plurality of associated playback speeds, with each playback speed associated with a segment or segment-type of the content. The playback speeds can be derived from any of one or more playback factors described herein. By way of example, the plurality of playback speeds for a piece of content can be stored in a playback profile. In the event content has multiple associated playback speeds, the playback speeds can be collected into a playback profile that can be transmitted with the content, or can be separately available from the content. When the content is provided to the user, the system can determine the playback speed associated with that segment or segment-type, and play the content for the user at the appropriate speed. In an aspect, no user intervention is required, or is only required to setup an initial user preference profile. Thus, by way of example, a movie can be consumed wherein the opening credits are automatically played at 1.5×, the action based introductory scene at 1.0×, scenes with no dialog at 2.0×, scenes with sub-titles at 0.8×, and closing credits at 2.0×. The playback speeds can be adjusted automatically, by monitoring transitions between segments and segment-types. 
     In an aspect, a plurality of different playback speeds can be utilized for a single piece of content, enabling the methods provided to determine when to apply each playback speed. Transitions between playback speeds can be immediate or can be gradual. For example, lead-in and/or lead-out markers indicating transition to/from a commercial can be utilized in determining when to apply a specific playback speed. In another aspect, certain keywords in closed caption data indicating a transition to commercial can be used as a playback factor, for example, if phrases such as “coming up,” “after the break,” and the like are recognized. These keywords combined with commercial detection and applause (often the audience is cheering/clapping on lead in/out) can determine where lead ins and outs are likely to exist. Keywords can be used for commercial detection, especially if closed captions are recorded between shows, and any commercial that appears more than once can be automatically detected (based on repeated closed captions). Playback speed transition can be based on laughter detection, the few seconds before laughing would likely be more important (the punch line) than the laughter itself. 
     In another aspect, the absence of closed caption data can be used as a playback factor to indicate a point at which transition between playback speeds is appropriate. The absence of closed caption data for a set period of time, for example, more than several or 10, 20, 30 seconds, and the like, can indicate a transition point for playback speed changes. In yet another aspect, a detected change in the display position of closed caption data can be used as a playback factor to indicate a transition point for playback speed changes. In another aspect, speech types can be used as a playback factor to indicate a transition point for playback speed changes. For example, laughter can be detected, indicating a punch line or situational gag that would be important to the user a few seconds before the laughter, while the laughter itself can be sped up considerably. 
     One or more modifiers can be assigned to various transition detection schemes that can adjust playback speed, for example, when combined with metadata. Crowd sourcing, by analyzing other user&#39;s habits of fast forwarding/rewinding, can be used to generate a heat map of which sections of the program are the most important, and playback speeds can be set or recommended accordingly (e.g., speed up the least popular portions). For example, if a crowd sourced heat map exists showing 50% of users fast forward between 4:30-6:30, an additional modifier of 1.1 might be multiplied to the calculation. But if the crowd sourced heat map exists showing that 70% of all users fast forward between 11:30-13:30, then a higher multiplier of 1.25 might be used.
