Mobility and Sociality are the two driving forces for new video based applications. With the development of Smart and wearable personal devices, mobile video applications will become more and more important. The easy-to-use mobile and social video applications will generate much more video data than traditional streaming/broadcasting video. Video surveillance will be more pervasive, which has generated more video than youtube (Dropcam, 2013). Not video call or face time, but Event Time, to show your friend what you are seeing.

With the improvement of QoE and user bandwidth, more and more user will be using the mobile video services. It is expected that LTE-A and the so called 4.5G will be the most popular MBB access points. A HD level mobile video quality is expected for mobile video services. A 2X better than HEVC codec will be basic for really massive video applications and services over Mobile Network for the next decade. Copyright2014 Huawei Technologies Co., Ltd.

Mobile processors are getting higher frequency and cores. Mobile device consumers are aware of power efficiency and functionalities greatly. The improvement of chip technologies will provide more computing ability for higher level functions while keeping the power consumption at a acceptable level. The development of future codec should take chip tech. into consideration. Copyright2014 Huawei Technologies Co., Ltd. All Rights Reserved. 10 Performance vs. Royalty Free Video Codec is a enabling technology for video services. For the current mobile video applications, cost per video bit is still too high for massive video services market which are blocking the development of innovation of video based mobile applications. It is important to have a better video codec for mobile video services first. Healthy balance between the royalty cost and the investment of new codec technologies is important.

Original questions What will be the applications with highest amount of video data delivery 5-10 years from now? Do you see market segments where HEVC may not be successful due to lack of functionality? How much additional compression (compared to HEVC) do you foresee to be needed for your market(s)? What are the desirable frame rates and resolutions? How would it affect your business (and in what time frame) if a new video codec would deliver 25% reduction in data rate for the same video quality compared to HEVC? What should be the bar to surpass to make a new standard? (in terms of tradeoff of compression benefit versus complexity, compatibility with existing designs, etc.) What would change if the industry uses the new codec as (partly or totally) royalty-free?
