Verifying the rendering of video content at client devices using trusted platform modules
11700433 · 2023-07-11 · ·

Systems and methods for verifying the rendering of video content on information resources are provided herein. A server can transmit a video content element having a first bit stream corresponding to a predesignated frame to a client device. The client device can identify the first bit stream as corresponding to the predesignated frame. The client device can decode the first bit stream corresponding to the predesignated frame of the video content element to generate a second bit stream. The client device can transmit, to the server, a tracking message including the second bit stream. The server can compare the second bit stream included in the tracking message from the client device with a third bit stream maintained at a database. The server can determine that the video content element is rendered at the client device responsive to the second bit stream matching the third bit stream.

A processor may manage media modification within a participant network. A processor may generate the participant network having a participant. The participant may be associated with one or more media data. A processor may enforce one or more rules on the participant network using an artificial intelligence (AI) based governance system. The one or more rules may manage the modification of the one or more media data by the participant. A processor may restrict the participant from modifying the one or more media data based, at least in part, on the AI based governance system.

Content distribution pipeline watermarking

Methods, computer-readable media, and devices for tracking an accessing of a media content via a watermark embedded by a network node are disclosed. For example, a processing system including at least one processor may receive, from a first network node, a first copy of a watermark that is embedded by the first network node in a media content. The processing system may further receive a notification comprising a second copy of the watermark and an identification of a first endpoint device, the notification associated with an accessing of the media content by the first endpoint device, and record the accessing of the media content by the first endpoint device.

A number of variations may include providing a computer system for networked video management, the computer system may include at least one computer having non-transitory memory for storing machine instructions that are to be executed by the computer, the machine instructions when executed by the computer implement the following web service proxy protocol: opening at least one first network connection from at least one video gateway device to at least one web service proxy application and opening at least one second network connection from the at least one video gateway device to at least one network camera on a server network; performing a scan for network cameras on the server network via the at least one gateway device and transmitting the results of the scan to the web service proxy application; and establishing at least one tunnel between the at least one network camera and the web service proxy application.

Generation and detection of private metadata in an encoded video transport stream

A method of processing a video transport stream includes receiving a video transport stream and identifying at least one portion of the video transport stream that is not to undergo modification when processed by a rate shaping device. An indicator is inserted into the video transport stream. The indicator is used to signal the statistical multiplexer that the at least one portion of the video transport stream is not to be modified when the video transport stream is processed by the rate shaping device.

Systems and methods for performing transport I/O

Systems and methods for implementing a Transport I/O system are described. Network encrypted content may be received by a device. The device may provide the network encrypted content to a secure processor, such as, for example, a smart card. The secure processor obtains a network control word that may be used to decrypt the network encrypted content. The secure processor may decrypt the network encrypted content to produce clear content. In embodiments, the secure processor may then use a local control word to generate locally encrypted content specific to the device. The device may then receive the locally encrypted content from the secure processor and proceed to decrypt the locally encrypted content using a shared local encryption key. The Transport I/O system ensures the protection of the network control word by maintaining the network control word on the secure processor.
