Novel Coding Tools Based on Characteristics for Short Videos Currently, short videos occupy large proportion of live streaming media and short video coding attracts intense attention. Different from traditional online videos, short videos feature frequent scene switching and allow various complex special effects to be added. For the unique characteristics of these short videos, we proposed an advanced video compression platform, which includes Library Picture based Cross Random Access Point Reference (LPCRAPR), Affinebased Intra Block Copy (AIBC) and Local Illumination Compensation (LIC), to meet the challenges of short video coding. The experimental results show that our proposed platform has performed 5.84% and 2.74% gain under Random Access (RA) and All Intra (AI) configuration compared to VTM 4.0, with approximately two times encoding complexity increasing and no additional decoding time. For our proposed short video coding, high coding efficiency and improved subjective results are achieved.

Next generation video coding for mobile applications : Industry requirements and technologies Handheld batteryoperated consumer electronics devices such as camera phones, digital still cameras, digital camcorders, and personal media players have become very popular in recent years. Video codecs are extensively used in these devices for video capture andor playback. The annual shipment of such devices already exceeds a hundred million units and is growing, which makes mobile batteryoperated video device requirements very important to focus in video coding research and development. This paper highlights the following unique set of requirements for video coding for these applications: low power consumption, high video quality at low complexity, and low cost, and motivates the need for a new video coding standard that enables better tradeoffs of power consumption, complexity, and coding efficiency to meet the challenging requirements of portable video devices. This paper also provides a brief overview of some of the video coding technologies being presented in the ITUT Video Coding Experts Group (VCEG) standardization body for computational complexity reduction and for coding efficiency improvement in a future video coding standard.
