Abstract: Systems and methods adapted for providing heterogeneous media services in communication systems, such as using transport layer security deferral and/or medium redirect, are disclosed. In operation according to embodiments, heterogeneous media services may be facilitated by obtaining, by a hybrid broadcast receiver of a receiver device, a computer parsable object comprising information regarding content segment availability and access, wherein the hybrid broadcast receiver is adapted to obtain content via both broadcast and broadband connections for a streaming client of the receiver device. The hybrid broadcast receiver of embodiments may further operate to evaluate the computer parsable object for one or more content segment entries indicating transport layer security is to be invoked with respect to a connection used for obtaining one or more content segments and to overwrite the one or more content segment entries preventing the transport layer security from being invoked by the streaming client.

Abstract: Information for a video stream indicating whether the video stream includes stereoscopic three-dimensional video data can be provided to a display device. This information allows the device to determine whether to accept the video data and to properly decode and display the video data. This information can be made available for video data regardless of the codec used to encode the video. Systems, devices, and methods for transmission and reception of compatible video communications including stereoscopic three-dimensional picture information are described.

Abstract: A block-request streaming system provides for improvements in the user experience and bandwidth efficiency of such systems, typically using an ingestion system that generates data in a form to be served by a conventional file server (HTTP, FTP, or the like), wherein the ingestion system intakes content and prepares it as files or data elements to be served by the file server. The system might include controlling the sequence, timing and construction of block requests, time based indexing, variable block sizing, optimal block partitioning, control of random access point placement, including across multiple presentation versions, dynamically updating presentation data, and/or efficiently presenting live content and time shifting.
