Simonbolek:

This topic provides an outline of requirements for a head unit. The requirements are derived from a real life development project for in-vehicle infotainment platform. ''This is still work in progress--the content will be added gradually.''

Some of the requirements below will be fulfilled outside of the MeeGo IVI based software. For example, the implementation of CAN network interface and early audio functions most probably falls into this category. The decisions about implementation of specific requirements in MeeGo IVI software will be made assuming a specific [[In-vehicle/Roadmap/SystemArchitecture|system architecture]].

=== Performance ===
# After power-on, the head unit displays a static splash screen within 200 ms.
# After power-on, the head unit displays an animated splash screen (pre-defined, fixed) within 200 ms and at the frame rate above 4 fps.
# After power-on, the head unit is able to play early audio (e.g. chimes and gongs--minimal set, best suited type, simple) within max. 1 s.
# After power-on, the head unit plays FM radio, resuming the last station before shut-down, within max. 2 s.
# After power-on, the head unit plays compressed audio from a connected media device (e.g. MP3 from USB stick), resuming the last track played before shut-down, within max. 2 s.
# After power-on, the head unit displays the rear view camera output within max. 2 s.
# After power-on, the head unit accepts first user input (e.g. HMI menu, screen, volume control) within max. 2 s.
# After power-on, the head unit displays the Navigation map and starts the route guidance, resuming the previous route, within max. 5 s.
# Head unit reacts to user input via HMI (touch screen events, button or switch presses) within max. 100 ms. Head unit displays interim response (e.g. sand glass) for all requests that cannot be completed within this time
# Head unit performs voice recognition for a single word against G2P vocabulary within max. 200 ms measured from the end of utterance (silence detection) to recognition result available (e.g. HMI display update or resulting voice prompt output).
# Head unit performs hand writing recognition against Chinese standard 2000 character set within max. 200 ms measured from end of entry to recognition result available (e.g. HMI display update or resulting voice prompt output).
# Head unit exhibits the refresh rate of min 15 fps for the navigation map in any scaling.
# Head unit exhibits a graphics rendering frame rate (for HMI animations and Navigation maps) of min. 15 fps.

== Audio ==
=== Audio_Codecs_Playback ===
# Head unit supports the following codecs:
## AAC LC
## MP3
## WMA
## WAV
## Ogg Vorbis
## FLAC

=== Audio_Processing_And_Management ===
# Head unit supports up to 4 independent audio zones (sinks). One zone if 5.1 channels (e.g. cabin speakers) and others are stereo. (Each zone might require its own independent audio processing and audio codec instances.)
# Head unit allows the user to adjust at least audio treble and bass level.
# Head unit allows the user to adjust balance and fade level.
# Head unit is capable of playing back any of its sources to any of 4 audio zones including simultaneous playback to up to 4 audio zones.
# Head unit uses pre-defined fader ramps when switching the audio source for any particular audio zone.
# For each audio zone, the head unit keeps track of the most recently played audio source and restores it upon startup. (For example, when the FM tuner was played to the cabin speakers and the head unit has been switched off, it would attempt tuning to the same FM station and putting it to the cabin speakers upon the next startup.)
# For each audio zone, all available audio sources are assigned a unique priority. When an audio source is being played back and a higher priority source becomes available (e.g. the phone application attempts to play a ring tone), the latter overrides the former.
## As a configuration option, overriding can be done either by muting the first source and playing back the second source, or by lowering the volume of the first source and mixing it with the second source.

=== Audio_Generation ===
# chimes and gongs
# calibration to interior

=== Audio_Recording ===
# voice
# radio
# podcasts

=== Audio_Volume_Control ===
# Volume level is adjustable by the user.
## Adjustments by the user are only accepted during actual audio playback. (In other words, any volume changes e.g. during start up phase and before the audio output can be heard will be ignored.)
## The volume level selection by the user is maintained for each audio source / sink pair individually.
# Volume level is adjusted by the head unit accordingly to the current vehicle speed.
# Volume level set by the user is preserved through shutdown cycle.
## Upon start up, the previous volume level is only restored up to a defined 'start up maximum' (as contrasted to the 'absolute maximum' that can be set after the head unit is up and running in its normal mode).
# Under limit volume need to be set as some low level NOT minimum just to make sure that at leaset user can recognize low level volume even though user set the volume to minimum "basically mute" before the power cycle
# Upper limit volume need to be set as some high level NOT maximum just to make sure that user can not be annoyed due to the previous maximum volume setting.
# In Emergency Case, volume should not be adjusted by the user, volume need to be fit as some very loud level as much as no sound is masked with ambient noisy backgroud,
