Description
Summary:High Efficiency Video Coding (HEVC) is the next coding standard that is being finalized by ITU's Joint Collaborative Team on Video Coding (JCT-VC). This paper compares the H.264/AVC, current coding standard, and HEVC (aka H.265) in mobile compute environments. In this study, the focus, within the mobile compute environment, are smart phones. The major smart phone elements are smaller screen size, which is typically 3.5 inches diagonal to 5.0 inches diagonal for high end smart phones and typical cellular network bandwidth, which is typically 3G or faster. There is compelling subjective test feedback that indicates human device interaction focused on user's experience is very similar between HEVC and H.264 encoding standards for mobile environment screen size and higher cellphone bandwidth (such as 400kbps constant bit rate). This suggests the benefits of HEVC over H.264 in mobile environment are not as clear.
