Wireless Video Broadcasting to Diverse Users

The growing diversity in media clients calls for content providers to adapt media content to adhere to their various needs. It is desirable to serve these heterogeneous users in a fast and efficient manner. Scalable media, such as H.264/MPEG- 4 SVC, helps make this possible. To account for various viewing capabilities of each user, such as different spatial or temporal resolutions, the Multiple Distortion Measures framework is used. MDM associates multiple distortion values with each packet depending on the user types (low/high resolution viewers, low/high frame rate viewers, etc.) who will consume the media packets. In this paper, the authors examine how to broadcast media packets with multiple distortion measures to multiple users.
