Abstract:
Video data is retrieved from a server. During retrieval of the video data, a client device receives information indicating bit rates of representations of multimedia content. In addition, the client device receives information indicating priority values for segments of the representations. The segments correspond to particular temporal sections of the representations. The client device requests selected ones of the segments based on the priority values for the segments and an estimated throughput. In some instances, the client device requests the segments in accordance with an adaptive streaming network protocol, such as Dynamic Adaptive Streaming over HTTP (DASH).
Abstract:
Methods and systems enable application content for use by an application running on a receiver device to be broadcast by a mobile multimedia broadcast network for energy-efficient reception and use by receiver devices. Information about application content that will be broadcast is broadcast in application metadata messages. Receiver devices may receive such application metadata messages in a broadcast receiver client which passes the information to the application. The application may inform the broadcast receiver client of particular application content or filtering attributes to use in selecting application content to be received. The broadcast receiver client receives the indicated application content at the designated broadcast time and passes the received content to the application for processing. In an embodiment the application is a Mobile Billboard Advertising (MobAd) application, the application metadata includes attributes about ad content and the broadcast application content includes ad content.
