DEMAND BASED SELECTION FOR CELLULAR BROADCAST STREAMING MEDIA

Aspects of the subject disclosure may include, for example, determining available media content items and identifying a first number of wireless broadcast channels of a wireless network having a limited channel capacity and adapted to broadcast media content items within a coverage area. A demand for a group of media content items is identified, and media content items are selected according to the demand, wherein broadcasting of the selected media content items within the coverage area does not exceed the limited channel capacity. The selected media content items are assigned to a group of broadcast channels of the first number of wireless broadcast channels to obtain a broadcast channel assignment for the coverage area. The wireless network is configured to broadcast the selected media content items within the coverage area via wireless broadcast channels according to the broadcast channel assignment. Other embodiments are disclosed.

Proxy Assisted Panoramic Video Streaming at Mobile Edge

Aspects of the subject disclosure may include, for example, system for tile-based video streaming using a proxy executing at a mobile edge cloud, which adaptively offloads decoding and merging of video tiles from mobile devices to the mobile edge cloud. A processing system including the proxy communicates with a video server and a client device. The proxy receives a request for video content from a client device; the request includes historical field of view (FoV) information. The proxy predicts a client FoV, requests video tiles from the server, downloads the tiles from the server, generates a video chunk by decoding and merging the downloaded tiles, and delivers the video chunk to the client device. The client device performs local decoding and rendering of the generated video chunk. Other embodiments are disclosed.
