Amazon.com: Cardio Athletic Kickboxing Home Workout Video - Order Form behindscenes.com |
"Unbox" redirects here. For the computer science term relating to data structures, see Autoboxing#Unboxing. Amazon Video On Demand (VOD) is an Internet video on demand service, only available in the United States, offered by Amazon.com which offers television shows and films for rental and purchase. The service became available on September 7, 2006 as Amazon Unbox.[1] On September 4, 2008, the service was rebranded as "Amazon Video on Demand." The Unbox name still refers to the locally-installed player, which is now optional.[2]
[edit] CompatibilityBy default, VOD programs play in Flash Video in all web browsers with the Adobe Flash plugin installed. This feature was launched in public beta July 17, 2008[3] and was released September 4, 2008.[2] Customers may also download videos to TiVo Series 2 and Series 3 DVRs, except those made for use with DirecTV (DirecTiVo). Sony BRAVIA TVs equipped with an Internet Video Link device can also use Amazon VOD directly through the TV's menu system. The optional Amazon Unbox player lets users download higher-quality copies of videos. The Unbox player is compatible only with the Windows XP family of operating systems and Windows Vista. Downloaded films include a full-resolution video file and can include a lower-resolution copy for portable devices. The content can be viewed using the Amazon Unbox Video Player, Windows Media Player, a Windows Media Center Extender such as an Xbox 360, a PlaysForSure portable device. Downloaded videos may be burned to a DVD for storage purposes, but the resulting DVD will not play on a DVD player. [edit] Video qualityAmazon.com describes the content as "DVD quality". The average video bit-rate of an Amazon Unbox download equals 2500 kbit/s; this means that a two hour movie consumes roughly two gigabytes (2 GB) of storage space. In comparison, a typical DVD averages 5600 kbit/s, which makes a 2-hour movie about 4.7 GB. However, Amazon uses the VC1 codec, a more modern codec than MPEG-2, which is used on DVDs. VC1 achieves a higher quality picture at a smaller file size. The quality for the TiVo files is advertised as being 2800 kbit/s and as being "of equal or better quality than videos recorded at the Best Quality setting on a TiVo Series2 DVR." [4] Due to the large size of the files being downloaded, the service requires a broadband internet connection capable of sustaining transfer speeds of 800 kbit/s. A 2-hour movie may take 7 hours and 20 minutes to download using a 750 kbit/s DSL/cable connection or 1 hour and 50 minutes with a 3.0 Mbit/s DSL/cable connection. Amazon asserts that for customers with an internet connection of 3 Mbit/s or more, any Unbox file will start playing within 5 minutes. In November 2007, TiVo enabled "progressive download" for Unbox content so that users may watch downloaded files before the download is complete. [edit] RequirementsUsers of the streaming video on demand service need only a web browser with the 32 bit Adobe Flash plugin to stream videos.[3] The 64 bit Flash Player for Linux is still in Alpha testing & does not work with Amazon.com Video-On-Demand. For transfer to portable device, the service requires the installation of a client application which manages playback and the transfer of video to portable devices that bear the Microsoft PlaysForSure certification, such as the Creative Zen or a Portable Media Center. For use with a TiVo DVR, no client application is needed. The user only needs a broadband enabled (and connected) Series2 or Series3 DVR. DirecTiVo DVRs are not supported. Sony BRAVIA TVs require an Internet Video Link to play Amazon VOD videos. Some models come equipped with this device; for other DMeX-capable models, a separate device must be purchased and installed.[5] Is also available on Panasonic TVs with VIERA CAST. http://www2.panasonic.com/consumer-electronics/learn/Televisions/vieracast [edit] Points of Differentiation
[edit] CriticismIn the first version of Unbox, a background service would launch itself upon system startup to phone home to see if there are any new videos to download. Also, the program will attempt to contact the Amazon server upon uninstall. This automatic behavior, which could not be disabled without uninstalling the Unbox application, drew negative reviews for its implicit permission to run arbitrary code as designated by Amazon.com personnel.[9] This is also confirmed in the video player's license agreement. In an upgrade released shortly after launch, thought to be a response to these criticisms,[10] Amazon made "launch on startup" optional, though disabling it necessarily disables the RemoteLoad feature, and makes the program impossible to run in non-administrator accounts. Rented Unbox movies cannot be transferred to a portable device. They can only be viewed on the device to which they are downloaded. [edit] Related Links
