“…Hence, watermarking enables identification and tracing of different copies of video data. Applications are video distribution over the World Wide Web (WWW), pay per view video broadcast, and video on demand services in mobile networks [15,16]. In the mentioned applications, the video data is usually stored in compressed format.…”

In the last years, tracing watermarking has been proposed as a technique to provide a blind measure of the quality of service of the communication link, focusing on multimedia communication scenarios. This paper is focused on 3G video-on-demand (VOD) communication scenarios. We have exploited the new color space YST, recently introduced in the literature, where the luminance component (Y) is the same as in conventional YUV space, while the vectors S and T lie within the chrominance (UV) plane. In particular, the third component T, defined as orthogonal to the YS plane, is chosen as the channel for the embedding process (instead of the Y channel). The results show the benefits obtained in digital watermarking by the new representation versus the conventional approach, i.e. the YUV color space. The main contribution of our work is twofold: the sensitivity of the YST representation outperforms the conventional one in terms of both quality (i.e. minimization of the alterations endured by the video during the embedding process) and security issues (i.e. detection of the watermark). Hence, the proposed procedure can be suitably applied for watermarking of 3G video-on-demand applications.

The past few years have seen an explosion in the popularity of online short-video sharing in YouTube. As the number of users continue to grow, the bandwidth required to maintain acceptable quality of service (QoS) has greatly increased. Peer-to-peer (P2P) architectures have shown promise in reducing the bandwidth costs; however, the previous works build one P2P overlay for each video, which provides limited availability of video providers and produces high overlay maintenance overhead. To handle these problems, in this work, we novelly leverage the existing social network in YouTube, where a user subscribes to another user’s channel to track all his/her uploaded videos. The subscribers of a channel tend to watch the channel’s videos and common-interest nodes tend to watch the same videos. Also, the popularity of videos in one channel varies greatly. We study real trace data to confirm these properties. Based on these properties, we propose SocialTube, which builds the subscribers of one channel into a P2P overlay and also clusters common-interest nodes in a higher level. It also incorporates a prefetching algorithm that prefetches higher-popularity videos. To enhance the system performance, we further propose the demand/supply-based cache management scheme and reputation-based neighbor management scheme. Extensive trace-driven simulation results and PlanetLab real-world experimental results verify the effectiveness of SocialTube at reducing server load and overlay maintenance overhead and at improving QoS for users.
