The server system receives, from a respective remote physical client device, a digest of a segment of video content received by the respective remote physical client device, the segment of video content including a plurality of frames of video content. In response to receiving the digest, the server system sends a playback command to the respective remote physical device to playback one or more of the plurality of frames of video content in the segment. The plurality of frames of video content in the segment have a frame rate. The server system determines a graphical processing unit (GPU) overlay instruction for overlaying content of a frame buffer with a respective portion of the segment of video content and sends, asynchronously from the frame rate of the plurality of frames of video content, the GPU overlay instruction to the respective remote physical client device.

Systems and methods of alternative networked application services

A client device receives media content from a server remote from the client device. During playback of the media content, the client device transmits, to a player proxy remote from the client device, a play position of the media content. The play position of the media content is used by the player proxy at the application server to continue providing the media content. The play position is transmitted repeatedly to the player proxy while playback of the media content continues. The client device transmits the media content for display at a display device that is coupled to the client device.

Remotely managed trusted execution environment for digital-rights management in a distributed network with thin clients

The server system transmits, from a virtualized third-party application to a client device, an instruction to open a media resource from a content distribution network, the media resource comprising a plurality of video segments, each video segment of the plurality of video segments having video segment data and metadata. The server system receives, from the client device, first metadata for a first video segment of the plurality of video segments, without receiving first video segment data for the first video segment. The server system generates a recreated representation of the first video segment using the first metadata. The virtualized third-party application generates a transformed version of the recreated representation of the first video segment. The server system transmits, to the client device, an instruction to play the first video segment, wherein the instruction is based on the transformed version of the recreated representation of the first video segment.

Systems and methods of orchestrated networked application services

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.

Managing deep and shallow buffers in a thin-client device of a digital media distribution network

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.

Multiple-mode system and method for providing user selectable video content

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.

Intelligent multiplexing using class-based, multi-dimensioned decision logic for managed networks

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.

Secure bridging of third-party digital rights management to local security

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.

Remotely managed trusted execution environment for digital rights management in a distributed network with thin clients

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.

A server system assigns a group of user sessions to a single modulator. The user sessions comprise data in a plurality of classes, each class having a respective priority. The plurality of classes includes, in order of priority from highest priority to lowest priority, audio data, video data, and user-interface graphical elements. The server system determines that an aggregate bandwidth for a first frame time exceeds a specified budget for the modulator. In response to determining that the aggregate bandwidth for the first frame time exceeds the specified budget, the server system transmits an allocated portion of the data for the group of user sessions through the modulator onto a channel corresponding to the modulator during the first frame time in accordance with the class priorities.

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 is received from the application server, decrypted using the unwrapped second key, and decoded for playback.

Methods for performing handovers and addition of carriers during carrier aggregation operation are described. A mobile station can indicate failure to perform downlink synchronization to some but not all cells of a target eNB, in response to a handover command. The mobile station can activate carriers based on various combinations of transmission of random access preambles, reception of random access response messages and transmission of handover complete messages. A base station can activate carriers based on various combinations of reception of random access preambles, transmission of random access response messages and reception of handover complete messages.

Handover during carrier aggregation operation in wireless communication network

A method in a wireless communication terminal supports aggregated carrier access. The terminal is configured to transmit a power headroom report of a first type, determine that a condition for transmission of a power headroom report of a second type is satisfied, and transmits a power headroom report of the second type. In other embodiments, essential power headroom reports are prioritized over non-essential power headroom reports.

Method and apparatus for power headroom reporting during multi-carrier operation

Methods for performing change of primary cell during carrier aggregation operation are described. A mobile station (MS) receives a message to change a primary cell and to perform a random access communication with a new primary cell. Upon receiving a random access response message from the new primary cell, the MS starts transmitting a control channel to the new primary cell. In one embodiment, the MS releases the configuration of an uplink control channel and transmits uplink control information through an uplink shared channel. Upon completion of the primary cell change procedure, the MS starts transmission of an uplink control channel to the new primary cell.
