For example, a computing device may generate a first token based on a private key and an encryption algorithm. The first token may be inserted into a link to a media stream. When the link is selected at a client device, a media request including the first token may be sent to a server. The server may generate a second token based on the private key and the encryption algorithm. The server may grant or deny the media request based on a comparison of the first token and the second token. | 01-22-2015 |
20140376623 | Distributed Encoding of a Video Stream - Systems and methods of configuring and performing distributed encoding of a video stream are disclosed. A method includes receiving a video stream at a computing device and receiving user input indicating a value of a local encoding parameter and a value of a remote encoding parameter. The method further includes encoding the video stream at the computing device based on the value of the local encoding parameter to generate a first encoded stream. The method includes sending the first encoded stream and the value of the remote encoding parameter to a media server. The media server is configured to generate a second encoded stream based on the value of the remote encoding parameter and the first encoded stream. | 12-25-2014 |
20140300813 | DECODING OF CLOSED CAPTIONS AT A MEDIA SERVER - Systems and methods of processing closed captions are disclosed. For example, a media server may receive a first video stream and first closed caption data associated with the first video stream. The media server may interpret at least one command included in the first closed caption data to generate interpreted closed caption data. The media server may transmit, to a destination device, a second video stream including second closed caption data that is generated based on the interpreted closed caption data. | 10-09-2014 |
20140282766 | On the Fly Transcoding of Video on Demand Content for Adaptive Streaming - Systems and methods of performing on the fly transcoding of video on demand content for adaptive streaming are disclosed. For example, a media server has access to a single rendition of a video on demand item. The media server receives a request from a computing device. The request is for a portion of one of a plurality of renditions of the video on demand item that are available for adaptive streaming, where each of the renditions has a distinct bitrate. In response to the request, the media server generates, on the fly, the requested portion of the requested rendition by transcoding a corresponding portion of the accessible rendition. The media server sends the generated portion to the computing device. | 09-18-2014 |
20140281014 | Insertion of Graphic Overlays into a Stream - A particular method includes receiving, at a media server, a request for a first rendition of a stream. The method also includes generating a portion of the first rendition. Generating the portion of the first rendition includes determining whether one or more first overlay images are enabled and inserting the one or more first overlay images into one or more frames of the portion of the first rendition conditioned on the one or more first overlay images being enabled. The method further includes sending the portion of the first rendition to a computing device. | 09-18-2014 |
