DETAILED DESCRIPTION
Embodiments of the invention provide a method, article and system for providing a hierarchical data structure of user volume preferences in an amplifier, to determine amplifier output volume settings for a particular A/V component, a channel/frequency within that component, or for designated prerecorded audio content. Currently, volume settings on amplifiers in home entertainment audio/video (A/V) systems are limited to a global factory-specified level, or to the previous volume level setting when the entertainment system was last used. In addition, current audio amplifiers provide users with audio balancing adjustment methods to bring all audio to a single pre-selected comfort level regardless of component, channel, or selection that is being played through the amplifier. Furthermore, methods do not currently exist to specify volume settings for different components, TV channels/radio frequencies, music albums, individual music tracks and selections, or other A/V content that are played through an amplifier.
Embodiments of the invention are configured for user specification of initial volume level settings for individual A/V components, individual TV channels, radio frequencies, music compilations and albums, and other A/V content. In embodiments of the invention, an amplifier is initially set at a global default volume level, and a volume level adjustment determination is subsequently made for the A/V component that is selected by the user for playback. A further volume level adjustment determination is made for audio content based on the TV channel, radio channel, or the A/V content to be played through the amplifier. The hierarchy of user defined volume settings that are used in volume level adjustment determinations are stored in a database, wherein the database is used in conjunction with software and logic devices to determine which A/V component is being used, and what the current selected audio content is. In response to a volume setting having been registered in the database, the logic device sends a signal to the amplifier to adjust the volume setting to match the stored volume setting for the selected A/V content.
FIG. 1 is a block diagram of an exemplary entertainment system 100 for implementing embodiments of the invention. An amplifier 102 is electrically connected to a series of ANV components (104, 106, 108) that represent common consumer electronic devices such as television and radio receivers, DVD, CD, MP3 players, etc. The amplifier 102 has a memory device 112 for storing volume settings in a database for the components, as well as storing volume settings for individual channels, frequencies, A/V content (movies, programs, albums, songs, etc.). A logic device 110 interacts with the memory device 112 for storing and accessing the user volume settings. In addition, the logic device 110 interacts with the amplifier's 102 output stage 114 to control the volume of the audio outputted through the speakers 116.
Table 1 is an example of volume settings that may be stored in memory device 112. The hierarchical volume control is represented in the column labeled as “Level.” In Table 1, the system (MediaCenter) and components are first assigned default or user specified global volume settings as exemplified in the setting column. The user may then define volume settings for individual channels, frequencies, and A/V selections as defined in the category and detail columns. For example, the media center amplifier may be set at a default level of 40 decibels (dB), however upon the selection of the television as the playback device, the media center amplifier will be adjusted down to a relative level of 35 decibels (dB). If the user chooses to watch television channel 13, the relative volume level is raised to 50 db, an indication that the station is perceived by the user to have a low level of volume, or that station broadcasts mellow or low key programs that are hard to hear. In a further example, CDs of various albums may be set at varying volume levels by the user, or even may be set by individual songs that are contained within the album.

Examples of situations requiring the application of embodiments of the invention are the following. A television set and a DVD player are routed through a common media center amplifier, with the DVD component having a fixed volume output significantly lower than that of the television set. A volume adjustment is required whenever the amplifier input is switched from the television source to the DVD source, or vice versa. In a second example, different television broadcast channels do not have the same volume level, such as the contrast between a channel specializing in action movies or infomercials with loud volumes contrasted with the relatively muted volume levels of Public Broadcasting Service network stations. In a final example, an MP3 digital music unit contains a wide variety of songs, many recorded at significantly different source data volumes levels, that require volume adjustments when different styles or initial volume recording levels of songs are randomly or sequentially selected.
FIG. 2A is a flowchart illustrating the application of system and component level volume settings according to embodiments of the invention. The process starts when the amplifier is turned on (block 200), and the amplifier initially assumes the volume (Vo) that the amplifier 204 was set to when it was last used (block 202). The volume table is subsequently read (block 206) in the volume settings database 208 within the amplifier 204. If there is a factory system media center default volume (VO) in volume settings database 208 (decision block 210 is Yes) the amplifier is then set to volume VO (block 212). A determination of the current A/V component in use (block 214) is made, and a search is conducted of the volume settings database 208 for user defined volume levels corresponding to the current A/V component. If a volume level has been defined for the A/V component (decision block 216 is Yes), volume level VO is set from the factory system media center default volume VO to VO′ to correspond to the volume settings database 208. The hierarchal volume setting process continues in FIG. 2B.
FIG. 2B is a flowchart illustrating the application of content level volume settings according to embodiments of the invention. A determination (decision block 220) is made if the current component supports the selection of individual channels or frequencies. If the component does support channels or frequencies (decision block 220 is Yes), a determination is subsequently made if there is a volume setting specified for the channel or frequency by the user in the volume settings database 208 (decision block 222). If there is a frequency or channel setting in the volume settings database 208 (decision block 222 is Yes), the volume VO or VO′ is set to VO′′. A further determination is subsequently made (decision block 226) if the current component supports the identification of A/V content (e.g., television program, CD, DVD, individual song or music track, etc.). When the component supports the identification of A/V content (decision block 226 is Yes), a determination is subsequently made for a volume setting specified for the A/V content by the user in the volume settings database 208 (decision block 228). If there is an A/V content setting in the volume settings database 208 (decision block 228 is Yes), the amplifier volume VO or VO′ or VO′′ is set to VO′′′ (block 230 and 232), and the process ends (block 234).
