CPC Class H04N

A processing accelerator includes a shared memory, and a stream accelerator, a memory-to-memory accelerator, and a common DMA controller coupled to the shared memory. The stream accelerator is configured to process a real-time data stream, and to store stream accelerator output data generated by processing the real-time data stream in the shared memory. The memory-to-memory accelerator is configured to retrieve input data from the shared memory, to process the input data, and to store, in the shared memory, memory-to-memory accelerator output data generated by processing the input data. The common DMA controller is configured to retrieve stream accelerator output data from the shared memory and transfer the stream accelerator output data to memory external to the processing accelerator; and to retrieve the memory-to-memory accelerator output data from the shared memory and transfer the memory-to-memory accelerator output data to memory external to the processing accelerator.

Content controller system comprising rendering server system comprising a plurality of servers. The servers receiving a plurality of segment render requests that correspond respectively to segments included in a set of media content item segments. The servers render the segments corresponding to the segment render requests using a media content identification and a main user identification. Rendering the segments comprises retrieving metadata from a metadata database associated with the media content identification, rendering the segments using the metadata, generating a main user avatar based on the main user identification, and incorporating the main user avatar into the segments. The servers can upload the segments to a segment database and update segment states in a segment state database to indicate that the segments are available. Other embodiments are disclosed herein.

Systems and methods for optionally restricting the rendering of particular content items. An example method comprising: receiving a plurality of content rendering options supported by a client device; determining a content item to be rendered, the content item being associated with a restriction attribute; selecting a content rendering option supported by the client device in view of the restriction attribute; generating a token comprising data associated with the selected content rendering option and the content item; receiving a client request from the client device, wherein the client request is associated with the content item and indicates a chosen content rendering option; comparing the data of the token with the chosen content rendering option indicated by the client request to determine a match; and granting the client device access to perform the chosen content rendering option on the content item based on the outcome of the determination of the match.
