A method is provided for streaming transcoded HLS video from a video asset to allow a minimum startup delay time. A method includes pre-transcoding a first number of the HLS chunks. Then, once a request is received from a remote HLS client for the HLS video asset, transmitting a number of the pre-transcoded chunks to the remote HLS player. The pre-transcoded chunks are transmitted during a startup period until real-time transcoded chunks can be received and processed by the remote HLS player at a time position to allow seamless transition from the pre-transcoded chunks.

Reduction of startup time in remote HLS

A method is provided that broadcasts channels to set top boxes (STB), processes them, and makes them available in ABR streaming format to clients in a home network. The method includes the steps of: transmitting a plurality of streams for each channel broadcast, wherein each stream is at a different bitrate and is segmentable into chunks; receiving the plurality of streams for one or more channels at the STB; and storing a plurality of segmentable chunk durations for each of the plurality of streams for each channel received. In some embodiments, HLS is packaged as MPEG transport without a manifest file, and a set top box (STB) caches HLS chunks for at least the consumer's most viewed channels, reducing acquisition time of those HLS streams. The STB reconstitutes the HLS playlist and chunks for delivery throughout the home.

Broadcast delivered HLS system

A content moving device which enables providing content stored on a first user device, such as a DVR, in a first format and resolution to be provided to a second user device, such as a portable media player (PMP) in a second format and resolution. The content moving device identifies content on the first user device as candidate content which may be desired by the PMP and receives the candidate content from the DVR. The content moving device transcodes the candidate content at times independent of a request from the PMP for the content. The content moving device may provide a list of available transcoded content to the PMP for selection, and provide selected content to the PMP. The content moving device may also provide information relating to any protection schemes of the content provided to the PMP, such as DRM rights and decryption keys. The content moving device performs the often computationally intense and time consuming transcoding of user content to enable the user to move content between different user devices in a convenient manner.

Moving content between set top box and end devices in home

A method is provided that determines whether to allow an application (app) for use or restrict the app on a set top box (STB). The method includes the steps of measuring at the STB, one or more resources used by the app; comparing at the STB, one or more thresholds set by an operator; and determining if the one or more resources used by the app exceed one or more thresholds set by the operator. Another method is provided that monitors applications (apps) that are installed a set top box (STB) for illegal or harmful activity by a policy manager. This method includes downloading and copying an app from an external source; installing or uninstalling the app into an application folder; providing a notification informing the policy manager of the installing or uninstalling of the app; and evaluating the app be installed or uninstalled.

A method provides an origin certificate that can be issued as a digital certificate online. The method includes receiving an origin digital certificate and an encrypted client device private key from an offline certificate authority wherein the client device private key is encrypted according to a private key encryption key PrKEK. The method further includes receiving from the client device, a request for a client device digital certificate and the encrypted client device private key, selecting a digital certificate template for the client device, the digital certificate template having attributes that vary according to the client devices, building the client device digital certificate from the origin digital certificate and the selected digital certificate template, signing the client device digital certificate with an online certificate authority signing key, and transmitting the signed client device digital certificate and the encrypted device private key.

Origin certificate based online certificate issuance

A method and system is provided for segmenting blocks of video data into chunks for consumption by player devices to create a new block to improve overall chunk creation. In one embodiment, issues that occur at the PCP block boundaries are handled by creating two chunks, one from the tail of content from the previous block and the other from the start of the new block, with the sums of the two chunks approximately equal to the target duration, improving manifest and chunk cadence creation. In another embodiment, chunks are created when the sinkrequests a new manifest regardless of whether a proxy chunk timer pulling data from the PCP block has expired or not.

Method and apparatus for segmenting data

A Digital Rights Management (DRM) system is provided that reduces time for a move transaction using DTCP-IP when a copy is moved back or checked back in to an originating Personal Video Recorder (PVR). During a DTCP MOVE transaction, instead of transferring the full asset in a check back in operation to the PVR, a unique and abbreviated representation of the original copy of the asset would be made for the transfer. This abbreviated representation takes the form of a hash constructed from a hashing function which uses characteristics of the asset as inputs. This hash will have to be a unique and near guaranteed indicator of the original content, to a high probability, so that the copy control system could live up to the spirit of the DTCP spec and the DLNA interoperability guidelines.

Copy count for DTCP with an abbreviation hash used for check in copy

A method and system are provided for processing a media stream including at least a portion of a media program in a player executed by a computer. The player is configured for: (a) receiving the media stream, wherein the media stream is comprised of one or more chunks; (b) subdividing the chunks into one or more packets, wherein one or more of the packets include video data; (c) obfuscating or de-obfuscating at least some of the video data; and (d) concatenating the video data into one or more frames for playback by the player.

Providing security to video frames

Systems and methods are provided for digital rights management of licensed media content. Client library components and server library components provide digital rights management services. A client-side hosting application accesses client library functionality through invocation of client application programming interfaces (APIs). A server-side hosting application accesses server library functionality through invocation of server APIs. Licenses for specific media content can be requested and issued, and appropriately licensed media content can be played. Client and server library components can function essentially absent direct communication, such as that employing a transport layer. Communications between client and server library components can be carried by the hosting applications.
