Mobile Game

Filed under: Mobile Games — Tags: — admin @ 2:41 am

A mobile game is a video game played on a mobile phone, smartphone, PDA or handheld computer. This does not include games played on handheld video game systems such as PlayStation Portable or Nintendo DS.

The first game that was pre-installed onto a mobile phone was Snake on selected Nokia models in 1998.[citation needed] Snake and its variants have since become the most-played videogame on the planet, with over a billion people having played the game.[citation needed]

Mobile games are played using the technologies present on the device itself. For networked games, there are various technologies in common use. Examples include text message (SMS), multimedia message (MMS) or GPRS location identification.

However, there are non networked applications, that simply use the device platform to run the game software. The games may be installed over the air, they may be side loaded onto the handset with a cable, or they may be embedded on the handheld devices by the OEM or by the mobile operator.

Mobile games are usually downloaded via the mobile operator’s radio network, but in some cases are also loaded into the mobile handsets when purchased, or via infrared connection, Bluetooth or memory card.

Distribution

Mobile games can be distributed in one of four ways:

* Over the Air (OTA) - a game binary file (typically BREW or JAVA) is delivered to the mobile device via wireless carrier networks.
* Sideloaded - a game binary file is loaded onto the phone while connected to a PC, either via USB cable or Bluetooth.
* Pre-installed - a game binary file is preloaded onto the device by the Original Equipment Manufacturer (OEM).
* Mobile browser download - a game file (typically Adobe Flash Lite) is downloaded directly from a mobile website.

In the US, the majority of mobile games are sold by the US wireless carriers, such as ATT, Verizon, Altel, Sprint and T-Mobile. In Europe, games are distributed equally between carriers, such as Orange and Vodaphone, and off-deck, third party stores such as Jamba, Jamster, Kalador and Gameloft. Third party, off-deck game stores have not yet taken off (as of 2007) in the US, as the US based carriers use a ‘walled garden’ approach to their business models.

The popularity of mobile games has increased in the 2000s, as over $3 billion USD worth of games were sold in 2007 internationally, and projected annual growth of over 40%.

3GP?

What is 3gp?

3GP is a multimedia container format defined by the Third Generation Partnership Project (3GPP) for use on 3G mobile phones.

3GP is a simplified version of the MPEG-4 Part 14 (MP4) container format, designed to decrease storage and bandwidth requirements in order to accommodate mobile phones. It stores video streams as MPEG-4 Part 2 or H.263 or MPEG-4 Part 10 (AVC/H.264), and audio streams as AMR-NB, AMR-WB, AMR-WB+, AAC-LC or HE-AAC. A 3GP file is always big-endian, storing and transferring the most significant bytes first. It also contains descriptions of image sizes and bitrate. There are two different standards for this format:

  • 3GPP (for GSM-based Phones, may have filename extension .3gp)
  • 3GPP2 (for CDMA-based Phones, may have filename extension .3g2)

Both are based on MPEG-4 and H.263 video, and AAC or AMR audio.

When transferred to a computer, 3GP movies can be viewed on Linux, Mac, and Windows platforms with programs such as VLC media player, RealPlayer, QuickTime, GOM Player and Media Player Classic.

Hardware support

  • Most 3G capable mobile phones support the playback and recording of video in 3GP format (memory, maximum filesize for playback and recording, and resolution limits exist and vary).
  • Some newer/higher-end phones without 3G capabilities may also playback and record in this format (again, with said limitations).
  • In iMovie ‘08, a movie exported using the “Tiny” setting is saved as a .3gp file and can be played on a Mac, an iPhone (as well as any other handset able to load and play the file), an iPod touch or using Apple’s .Mac Web Gallery service.
  • Audio imported from CD onto a PlayStation 3 will copy onto USB devices in the 3GP format.

Ringtone?

What is ringtone?

A ringtone or ring tone is the sound made by a cell phone to indicate an incoming call. The term is a misnomer, as it is often used to refer to any ring sound, almost all of which are not tones. The term is most often used to refer to the customizable sounds used on mobile phones.

A phone “rings” when its network indicates an incoming call and the phone thus alerts the user. For landline telephones, the call signal can be an electric current generated by the switch to which the telephone is connected. For mobile phones, the network sends the phone a message indicating an incoming call.

A telephone “ring” is the sound generated when there is an incoming telephone call. The term originated from the fact that early telephones had a ringing mechanism consisting of a bell and an electromagnetically-driven hammer, producing a ringing sound. The aforementioned electrical signal powered the electromagnet which would rapidly move and release the hammer, striking the bell. This “magneto” bell system is still in widespread use. The ringing signal sent to a customer’s telephone is AC at 90 volts and 20 hertz in North America. While the sound produced is still called a “ring”, more-recently manufactured telephones electronically produce a warbling, chirping, or other sound. Variation of the ring signal can be used to indicate characteristics of incoming calls (for example, rings with a shorter interval between them might be used to signal a call from a given number).

Types of ring tones

Monophonic
A monophonic ring tone is simply a series of notes, one musical note at a time.

Polyphonic
A polyphonic ring tone can consist of several notes at a time. The first polyphonic ring tones used sequenced recording methods such as MIDI. Such recordings specify what synthetic instrument should play a note at a given time, and the actual instrument sound is dependent upon the playback device.

Truetone
A truetone (also known as “realtone”, “mastertone”, “superphonic ringtone” or “audio recording”) is simply an audio recording, typically in a common format such as “MP3″, AAC, or WMA, and represents the latest evolution of the ring tone. Truetones, which are often excerpts from songs, have become popular as ring tones.
