Mobile Video


Mobile video demand is exploding. With the people in the multimedia access whenever and wherever possible needs of the increasingly urgent, TV or receiving services will emerge as the times require. For the service provider, which is a good thing, they are hope for its product portfolio to add new consumer applications; but at the same time, the support infrastructure equipment presents a great challenge, not to mention the potential problems: from media gateway video required performance must meet the requirement of the low power consumption, so that not give infrastructure caused heavy burden, but also must meet the cost control and sustainability requirements.
New processor and streaming architecture in video transcoding achieve obvious advantages -- and the infrastructure equipment commonly used processor technology, some new product power / density ratio is improved by 15 times, can help to create a high performance, low power consumption of the mobile video platform solutions.
Mobile video and TV or receiving service development
In the second half of 2009, according to some market analysis shows, YouTube of average daily handle about 1000000000 video access. In 2008, the number is 6000000. More the report points out, to 2015, will have 12000000000 sets of equipment ( including television, computers, laptops, netbooks and smartphones ) accessed 500000000000 hours of video information. (source: Intel ). By 2013, mobile video telephone retains the quantity will achieve 400000000 (source: inquiry Thai ). In 2012, the video will account for all Internet traffic of 90%; in 2013, the video will account for all mobile communication flow 70% (source: Cisco ). Obviously, the wide and easy access to the video content is a huge consumer demand, and the demand is increasing day by day. To meet this demand and maintain access to the ease of use, for processing and delivery of such video content server, streaming video and media gateway number must be accompanied by processing work load surge and exponentially expanding. With the sound signal and other typical Internet content, video needs higher level processing capacity, particularly when the video is transmitted to the various types of browser on a client device is even more so. Of course, to enhance the processing ability also means the increase of energy consumption.
Video coding conversion is the processing load in the main part, combined with the growth, this task has a huge potential energy consumption growth, the existing infrastructure to make very great pressure.
On the demand of video transcoding
To distribute video from various capture equipment, they have different resolution and coding ability. For example, the application of MPEG4 encoding CIF smart phone or H.264 encoding a 720 pixel camcorder can be used as capture device. Similarly, for receiving the video client devices also have different decoding capability ( ability to decode for device function or processor cycles vary ), for example, QCIF H.263 cellular phone, decoding HD H.264 high-end notebook computers. Video uploaded to the network broadcast and / or storage, its purpose is to hope that anyone can see, however, there is a lack of rigid or general video exchange standard. To meet this objective, video distribution and Internet service provider must provide transparent code conversion function.
In addition, the video transmission expectations has become the requirements of real-time video transmission, and does not need to be a part of or the entire video download file to the client device in a buffer, on Internet television and monitor system especially. The real-time transmission demand to increase the video transmission system load, at the same time, also increases the energy consumption.
