## Background
BACKGROUND
Conventional multimedia systems allow a user to experience multimedia data playback. These systems typically provide a limited range of experience. For example, audiovisual playback systems may provide a user with a multimedia experience consisting solely of audio and video data from a film. Some auxiliary devices that may enhance a user's experience of a multimedia feature, such as ambient lights or robotic animated characters, are known in the art. However, their implementation with conventional multimedia systems is often costly, due to the specific nature of multimedia data streams. These implementations often require external audio-visual mixing processes, or costly stage management systems, unsuitable for home use. Accordingly, systems and methods for enhancing multimedia experience are needed.

FIG. 1 illustrates a computer system 111 upon which an embodiment of the present invention may be implemented. The computer system 111 may include a bus 112 or other communication mechanism for communicating information, and a processor 113 coupled with the bus 112 for processing the information. The computer system 111 also may include a main memory 114, such as a random access memory (RAM) or other dynamic storage device (e.g., dynamic RAM (DRAM), static RAM (SRAM), and synchronous DRAM (SDRAM)), coupled to the bus 112 for storing information and instructions to be executed by processor 113. In addition, the main memory 114 may be used for storing temporary variables or other intermediate information during the execution of instructions by the processor 113. The computer system 111 may further include a read only memory (ROM) 115 or other static storage device (e.g., programmable ROM (PROM), erasable PROM (EPROM), and electrically erasable PROM (EEPROM)) coupled to the bus 112 for storing static information and instructions for the processor 113.
The computer system 111 may also include a disk controller 116 coupled to the bus 112 to control one or more storage devices for storing information and instructions, such as a magnetic hard disk 117, and a removable media drive 118 (e.g., floppy disk drive, flash memory drive, read-only compact disc drive, read/write compact disc drive, compact disc jukebox, tape drive, and removable magneto-optical drive). The storage devices may be added to the computer system 111 using an appropriate device interface, including, for example, a small computer system interface (SCSI), integrated device electronics (IDE), enhanced-IDE (E-IDE), direct memory access (DMA), ultra-DMA, a serial port connection, a parallel port connection, USB, IEEE 1394 (FireWire), Bluetooth, Wi-Fi, or any other type of connection or interface known in the art.
The computer system 111 may also include special purpose logic devices (e.g., application specific integrated circuits (ASICs)) or configurable logic devices (e.g., simple programmable logic devices (SPLDs), complex programmable logic devices (CPLDs), and field programmable gate arrays (FPGAs)).
The computer system 111 may also include a display controller 119 coupled to the bus 112 to control a display 120, such as a cathode ray tube (CRT), liquid crystal display (LCD) or any other type of display, for displaying information to a computer user. The computer system may include input devices, such as a keyboard 121 and a pointing device 122, for interacting with a computer user and providing information to the processor 113. Additionally, a touch screen could be employed in conjunction with display 120. The pointing device 122, for example, may be a mouse, a trackball, or a pointing stick for communicating direction information and command selections to the processor 113 and for controlling cursor movement on the display 120. In addition, a printer may provide printed listings of data stored and/or generated by the computer system 111.
The computer system 111 may perform a portion or all of the processing steps of exemplary embodiments of the invention in response to the processor 113 executing one or more sequences of one or more instructions contained in a memory, such as the main memory 114. Such instructions may be read into the main memory 114 from another computer-readable medium, such as a hard disk 117 or a removable media drive 118. One or more processors in a multi-processing arrangement may also be employed to execute the sequences of instructions contained in main memory 114. In alternative embodiments, hard-wired circuitry may be used in place of or in combination with software instructions. Thus, embodiments are not limited to any specific combination of hardware circuitry and software.
As stated above, the computer system 111 may include at least one computer-readable medium or memory for holding instructions programmed according to the teachings of exemplary embodiments of the invention and for containing data structures, tables, records, or other data described herein. Examples of computer-readable media are compact discs, hard disks, floppy disks, tape, magneto-optical disks, PROMs (EPROM, EEPROM, flash EPROM), DRAM, SRAM, SDRAM, or any other magnetic medium, compact discs (e.g., CD-ROM), or any other optical medium, punch cards, paper tape, or other physical medium with patterns of holes, a carrier wave (described below), or any other medium from which a computer can read.
Stored on any one or on a combination of computer-readable media, exemplary embodiments of the present invention may include software for controlling the computer system 111, for driving a device or devices for implementing exemplary embodiments of the invention, and for enabling the computer system 111 to interact with a human user. Such software may include, but is not limited to, device drivers, operating systems, development tools, and applications software. Such computer-readable media may further include the computer program product of exemplary embodiments of the present invention for performing all or a portion (if processing is distributed) of the processing performed in implementing exemplary embodiments of the invention.
The computer code devices of exemplary embodiments of the present invention may be any interpretable or executable code mechanism, including but not limited to scripts, interpretable programs, dynamic link libraries (DLLs), Java classes, and complete executable programs. Moreover, parts of the processing of exemplary embodiments of the present invention may be distributed for better performance, reliability, and/or cost.
The term “computer-readable medium” as used herein refers to any medium that may participate in providing instructions to the processor 113 for execution. A computer-readable medium may take many forms, including but not limited to, non-volatile media, volatile media, and transmission media. Non-volatile media includes, for example, optical, magnetic disks, and magneto-optical disks, such as the hard disk 117 or the removable media drive 118. Volatile media may include dynamic memory, such as the main memory 114. Transmission media may include coaxial cables, copper wire and fiber optics, including the wires that make up the bus 112. Transmission media also may also take the form of acoustic or light waves, such as those generated during radio wave and infrared data communications. Transmission may be accomplished using, for example, a serial port connection, a parallel port connection, USB, IEEE 1394 (FireWire), Bluetooth, Wi-Fi, or any other type of connection or interface known in the art.
Various forms of computer-readable media may be involved in carrying out one or more sequences of one or more instructions to processor 113 for execution. For example, the instructions may initially be carried on a magnetic disk of a remote computer. The remote computer can load the instructions for implementing all or a portion of exemplary embodiments of the present invention remotely into a dynamic memory and send the instructions over a telephone line using a modem. A modem local to the computer system 111 may receive the data on the telephone line and use an infrared transmitter to convert the data to an infrared signal. An infrared detector coupled to the bus 112 can receive the data carried in the infrared signal and place the data on the bus 112. The bus 112 may carry the data to the main memory 114, from which the processor 113 may retrieve and execute the instructions. The instructions received by the main memory 114 may optionally be stored on storage device 117 or 118 either before or after execution by processor 113.
The computer system 111 may also include a communication interface 123 coupled to the bus 112. The communication interface 123 may provide a two-way data communication coupling to a network link 124 that may be connected to, for example, a local area network (LAN) 125, or to another communications network 126 such as the Internet. For example, the communication interface 123 may be a network interface card to attach to any packet switched LAN. As another example, the communication interface 123 may be an asymmetrical digital subscriber line (ADSL) card, an integrated services digital network (ISDN) card or a modem to provide a data communication connection to a corresponding type of communications line. Wireless links, using, for example, Wi-Fi or Bluetooth, may also be implemented. In any such implementation, the communication interface 123 may send and receive electrical, electromagnetic or optical signals that may carry digital data streams representing various types of information.
The network link 124 typically may provide data communication through one or more networks to other data devices. For example, the network link 124 may provide a connection to another computer or remotely located presentation device through a local network 125 (e.g., a LAN) or through equipment operated by a service provider, which may provide communication services through a communications network 126. In preferred embodiments, the local network 124 and the communications network 126 preferably use electrical, electromagnetic, or optical signals that carry digital data streams. The signals through the various networks and the signals on the network link 124 and through the communication interface 123, which carry the digital data to and from the computer system 111, are exemplary forms of carrier waves transporting the information. The computer system 111 can transmit and receive data, including program code, through the network(s) 125 and 126, the network link 124 and the communication interface 123. Moreover, the network link 124 may provide a connection through a LAN 125 to a mobile device 127 such as a personal digital assistant (PDA) laptop computer, or cellular telephone. The LAN communications network 125 and the communications network 126 both use electrical, electromagnetic or optical signals that carry digital data streams. The signals through the various networks and the signals on the network link 124 and through the communication interface 123, which carry the digital data to and from the system 111, are exemplary forms of carrier waves transporting the information. The processor system 111 can transmit notifications and receive data, including program code, through the network(s), the network link 124 and the communication interface 123.
