Abstract: The method of providing audiovisual content to a client device configured to be coupled to a display. The method detects a selection of a graphical element corresponding to a video content item. In response to detecting the selection of the graphical element, a transmission mode is determined. The transmission mode is a function of: (i) one or more decoding capabilities of the client device; (ii) a video encoding format of the video content item; (ii) whether the video content item should be displayed in a full screen or a partial screen format; and (iv) whether the client device is capable of overlaying image data into a video stream. Next, audiovisual data that includes the video content item is prepared for transmission according to the determined transmission mode. Finally, the prepared audiovisual data is transmitted from the server toward the client device, according to the determined transmission mode, for display on the display.

Abstract: A client device receives, from a server, first content directed to a first buffer in the client device and second content directed to a second buffer in the client device. The client device buffers the first content in the first buffer and buffers the second content in the second buffer. At least a portion of the second content is buffered in the second buffer substantially simultaneously with buffering the first content in the first buffer. The client device receives a command from a virtual set-top application, running on the server, that corresponds to the client device. The client device runs a virtual set-top local client that receives the command from the virtual set-top application and selects the first buffer as a content source. The selecting is performed in accordance with the command. The client device provides the selected content for display.

Abstract: Encrypted content from a content provider is received at a central location of a multichannel video programming distributor (MVPD). The content provider is distinct from the MVPD. The content is decrypted and processed in a virtual set-top application associated with a set-top of a customer of the MVPD. The set-top of the customer is located in a customer premises remote from the central location. The processed content is provided over a secure data link to a conditional-access encoder at the central location. The conditional-access encoder encrypts the processed content, which is then transmitted to the set-top of the customer.

Abstract: A method is performed at a client device distinct from an application server. In the method, a first key is stored in a secure store of the client device. A wrapped second key is received from the application server. The first key is retrieved from the secure store and used to unwrap the second key. Encrypted media content and a media control command to control playback of the media content is received from the application server. The content is decrypted using the unwrapped second key, and decoded for playback. During playback of the media content, a play position of the decrypted media content is transmitted to the application server and the decrypted media content is transmitted to a display device that is coupled to the client device. The decrypted media content is displayed in accordance with the received media control command.

Abstract: A client device receives, from a server, first content directed to a first buffer in the client device and second content directed to a second buffer in the client device. The second buffer is deeper than the first buffer. The client device buffers the first content in the first buffer and buffers the second content in the second buffer. At least a portion of the second content is buffered in the second buffer simultaneously with buffering the first content in the first buffer. The client device selects between the first content in the first buffer and the second content in the second buffer, and provides the selected content for display.

Abstract: A server system determines, for a group of user sessions assigned to a single modulator, that an aggregate bandwidth for a first frame time exceeds a specified budget for the modulator. The user sessions comprise data in a plurality of classes, each class having a respective priority. In response to a determination that the aggregate bandwidth exceeds a specified budget, the server system allocates a portion of the aggregate bandwidth, including allocating a first portion of the data for a first user session in the group of user sessions and allocating a second portion of the data for a second user session in the group of user sessions, where both the first portion and the second portion are allocated in accordance with the class priorities. The server system transmits the allocated portions of the data for the group of user sessions through the modulator during the first frame time.
