This chapter describes the graphic environment available in the W760r/VA76r handset. It includes
information on picture and animation formats, size restrictions, pre-defined media, and more. Use this
chapter as a reference when creating pictures or animations.
In general, file size is limited by available memory. All media (wallpaper, screensavers, ring tones, and
themes), whether pre-loaded on the device or downloaded by the user, share the same storage area. The
available memory for downloaded files varies based on the media pre-loaded into the device. This pre-
loaded media varies from region to region and from carrier to carrier. Motorola recommends keeping all
media files as small as possible to ensure the consumer has the ability to download and use a variety of
files to enhance the user experience.
Supported Picture Formats
The W760r/VA76r handset supports the following graphic and animation formats:
Table 2 Graphic and animation formats

This chapter describes the sound environment available in the W760r/VA76r handset. It includes
information on sound formats and more. Use this chapter as a reference when creating sounds for your
products.
In general, file size is limited by available memory. The available memory for downloaded files varies
based on the media that is pre-loaded into the device. This pre-loaded media varies by region and carrier.
We recommend keeping all media files as small as possible to ensure the consumer has the ability to
download and use a variety of files to enhance the user experience.
Alert Tone Support
Downloaded audio files can be applied to a number of alert tones on the device including ring tones for
incoming calls, Text Message, and Date Book Alarms.
Ring Tones
Ring tones should not exceed 30 seconds because most voice mail systems pick up after four rings (16-
25 seconds depending on the system).

MIDI Support
The Musical Instrument Digital Interface (MIDI) enables consumers to use multimedia computers and
electronic musical instruments to create, enjoy, and learn about music.
The MIDI protocol is a music description language in which every word describes an action of musical
performance. Each action is stored as a binary word, and when combined, stored as MIDI files. These
files can then be replayed by any electronic device that can read the MIDI file and recreate the
performance using its available sound system.

MIDI Audio Guidelines
The following are suggested guidelines to maximize sound quality while reducing the overall file size of a
MIDI Ring Tone file for use with the W760r/VA76r handset.
Tip 1: Use MIDI’s running status feature
In the MIDI standard, a key-on or a key-off event uses, at most, three bytes each. However, when several
key events occur on the same MIDI-channel, the running status feature can be used. In principle, running
status means the first byte of a key-on event is omitted. In addition, the key-on event having a velocity of
zero is equivalent to the key-off event. Thus, combining running status with key-on events that have zero
velocity reduces the number of bytes needed to encode all key events.
EXAMPLE:
Without using the running status feature, the following sequence:
91 2E 23 8E, 91 2B 50 8E, 81 2E 64 00, 81 2B 64 00
represents “Key 2E ON” Velocity 23 MIDI Ch 1”, “Key 2B ON Velocity 50 MIDI
Ch 1”, “Key 2E OFF Velocity 64 MIDI Ch 1”, “Key 2B OFF Velocity 64 MIDI Ch
1”. Using the running status feature reduces the sequence to:
91 2E 23 8E, 2B 50 8E, 2E 00 00, 2B 00 00,
That is, the command byte is omitted and velocity zero is used for key off.
Tip 2: Use Standard MIDI File (SMF) type 1
The MIDI content can be stored in a Standard MIDI File (SMF) of type 0 or type 1. In a type 0 SMF, the
file format uses one header chunk with one-track chunk. In a type 1 SMF, the format uses one header
chunk with several track chunks. SMF type 2 should not be used.
In general, it is more efficient to store the MIDI data as a type 1 file. The increased efficiency is achieved
because each track contains only one MIDI channel and one instrument, as is often the case. The
running status feature can be applied on each individual track, thereby reducing the track size. To reduce
the size of the file even further, use one track for each MIDI channel. That is, if a temple/conductor track
exists, merge it with the first instrument track and remove all unnecessary meta-events such as the “track
name” and “lyric” meta-events.
W760r/VA76r Media Guide
Page 31
Sound
To summarize, the following measures can be taken in order to reduce the SMF:
1
2
3
4
5
6
7
8
Use SMF type 1 (or verify that a type 1 file is smaller than a type 0 file and use the smallest file).
Use running status.
One and only one instrument per track. Try not to change channels.
Do not change tempo in the middle of the music. That is, set the tempo once.
Use beat, instead of SMPTE, to set the tempo.
Do not use Copyright Text Fields.
Limit the use of continuous controller information such as pitch-bend and volume.
Turn off the options below:
•
•
•
•
•
•
•
•
•
Sequence Number - MIDI sequence ids
Text - embedded text for any optional fields
Sequence / Track Name
Instrument Name
Lyric
Marker - for synchronization purposes
Cue Point
Midi Channel Presix - associate channels with all events following
Sequencer-Specific settings
Items one through three above optimize the encoding of the notes, while items four to eight optimize the
overall melody. The above measures provide an SMF file that is ready-made for compression. However,
prior to compression, the composer/content author can add a few values for key velocity, thereby
increasing the redundancy of the file.
Tip 3: Consider the Frequency Response
Even though the MIDI synthesizer is sampled at 22 KHz, the polyphonic speaker’s frequency response is
not as wide. Try to keep the majority of melodic information below 6000 Hz.
NOTE: The use of MIDI notes below 800 Hz may cause a decrease in volume when playing the note.
Always test your audio on an actual device to ensure the accuracy of the sound you want to produce.

MP3 Audio Guidelines
MP3 (MPEG Audio Layer 3) is an audio compression technology that is part of the MPEG-1 and MPEG-2
specifications. Developed in Germany in 1991 by the Fraunhofer Institute, MP3 uses perceptual audio
coding to compress CD-quality sound by a factor of 12, while providing almost the same fidelity. Because
MP3 audio is digitized, not synthesized, reproduction (disregarding speaker quality) is identical on all
devices. Therefore MP3 ring tones provide a near-CD quality audio experience for listeners as opposed
to their MIDI counterparts that differ greatly from device to device.
The following recommendations should be used when designing MP3 audio clips for use in the phone.
Technical Specifications for MP3:
•
•
•
Bit Rate: 64kbps recommended
Recommended file size: 30kb
Maximum duration (NW dependent): 16-30 secs
Available Sound Properties
Follow technical specifications outlined above.
Design Guidelines
Since ring tones need to be at a consistent audible level, compressing the original content to reduce the
peak-to-average ratio is necessary. After the audio is compressed, it is advisable to re-normalize the
audio to 0db before saving the compressed MP3 file.
NOTE: Ring tones are generally between 15-20 seconds in length. Based on the recommended bit
rates, that duration would yield a file size of 75-150K per ring tone. It is advisable to keep file size less
than 100K to allow the end-user to download multiple tones, but file size is limited only by the total
free memory available on the device.

Appendix A DRM
Digital Rights Management
Digital Rights Management (DRM) is a method of protecting content from illegal distribution by
embedding the content into an encrypted package along with rules dictating its use. Using a set of keys
and a license for the specific file, a DRM application is required to decrypt the content for playback. The
DRM application is transparent to the user except for the cases where the user acquires a file without a
proper license. Applications that interact with DRM encoded files include the following:
•
•
•
•
•
•
Media Center
MMS
EMS
Browser
Email
KJava

Supported DRM Solutions
The following three DRM solutions are supported by Motorola handsets.
•
Forward Locking – Forward locking construct defined by the OMA DRM specification. Similar to NDIS
implementation in MMS/EMS.
•
Combined Delivery – The OMA Combined Delivery mechanism is an extension of OMA forward
locking. The Combined Delivery mechanism differs by including a rights object within the DRM
message that governs the consumption of the content included along with the rights object. A handset
that supports Combined Delivery supports OMA forward locking.
•
Separate Delivery – The OMA Separate Delivery mechanism is an extension of OMA Forward
locking. The Separate Delivery mechanism differs by delivering the content and the rights object
separately. The W760r/VA76r handset supports retrieving rights via WAP Push.
Download
Forward Lock files are downloaded within a DRM message. The download manager recognizes the DRM
message of MIME type ‘application/ vnd.oma.drm.message’ as a valid file type.
The download manager discards any DRM message that contains more than one media object within the
DRM message.
OMA Combined Delivery is downloaded within a DRM message and consists of a media object and a
rights object. The download manager recognizes the DRM message MIME type and the MIME type
‘application/vnd.oma.drm.rights+xml’ as a valid file type. A single media object in the body of the DRM
message, that is encoded in the following identity transfer encoding ‘7bit’, ‘8 bit’, and ‘binary,’ is accepted
by the download manager.
