Abstract

Developing a content-aware coding scheme that delivers ensured QoE for end-users includes finding out which content information will be most needed; especially when wireless networks are used to send video information. Wireless in-home networks suffer from interference which creates variable throughput, which causes problems when sending video material from one device to another. Temporal and quality scaling provide classes for video adaptation methods that can handle this variable throughput. Presented research concerns the effect of temporal scaling versus quality scaling on different kinds of video content. We looked at the difference in perceived video quality between I-Frame Delay (temporal scaling) and TransCoding (quality scaling). Results show that I-Frame Delay scored better for video content without a lot of background movement, while TransCoding was scored better for scenes with lot of background movement. There are also indications that information about scene changes can be helpful to create content-aware coding.
