A playback device includes a port configured to receive content from an external memory device, a device memory residing in the device, and a controller programmed to execute instructions that cause the controller to read a read data pattern from the defined region in the external memory device and determine if the read data pattern correlates to an expected data pattern to a predetermined level, wherein the expected data pattern is derived at least in part from a defect map of the defined region.

Example embodiments of the disclosure may provide a recompressor system that configures dynamic Video Ad Serving Template (VAST) tags enabling seamless delivery of mezzanine-level quality video ads of the highest resolution compatible with the user's system requirements. Aspects of the disclosure relate to reprocessing of received VAST tag, parsing the tag to identify the location of the video of highest resolution, accessing the video of highest resolution and forwarding it to a compression engine (Euclid's in this case). Compression engine re-compresses video in one or more formats and sends back location(s) of the videos. Receiving back one or more video locations and an updated VAST tag and forwarding that.

Method for dynamic video compression in an ad delivery ecosystem

A method and apparatus for playing back a media content instance is disclosed. The method permits the use of downloadable variants to upgrade or change cryptographic functions performed by the playback device, thus permitting content protection schemes to be renewed.

Content distribution with renewable content protection

A playback device includes a port configured to receive content from an external memory device, a device memory residing in the device, and a controller programmed to execute instructions that cause the controller to read a read data pattern from the defined region in the external memory device and determine if the read data pattern correlates to an expected data pattern to a predetermined level, wherein the expected data pattern is derived at least in part from a defect map of the defined region. A memory device includes an array of memory cells configured to store at least one bit of data, the array of memory cells being organized into regions, at least one first region of the array of memory cells having stored therein a defect map of the array of memory cells, and at least one second region of the array of memory cells being designated as a defined region having a known defect pattern. A method of validating a memory device includes writing, using a controller in a playback device, a known data pattern to a defined region in the memory device, reading, with the controller, a read data pattern from the defined region, comparing, at the controller, the read data pattern to an expected data pattern, the expected data pattern derived from the known data pattern and a defect map of the defined region, and validating, with the controller, the memory device based upon a correlation result from the comparing.

A method of playing content across a network includes receiving, at a media player, an input from a user selecting media located on a network, sending a request across a network comprised of devices employing a common security protocol, the request to identify peer devices on the network, receiving a response across the network from a peer device, and accessing the media from a content memory of the peer device. A method of tracking valid peers on a secure media network, includes receiving, at a media player, an input from a user selecting media located on a peer device on the network, performing an authentication test of the peer player, determining if a latency associated with the peer player meets a criteria, and updating a latency log on the media player to include the peer player. A device has a content memory to store media content for playback, a network port arranged to allow the device to access a network, and a controller programmed to send a request through the network port to a network, the request being for a particular media content file, communicate with a peer device across the network to authenticate a communication session with the peer device, receive a response from the peer device indicating that the session has been authenticated, and access the media content file on a content memory on the peer device.
