Abstract: Techniques for secure fast channel change in live content streaming are described. In some embodiments, during content preparation, a packager and/or an encoder encrypts media content items at both the service level (e.g., by encrypting a first portion of the plurality of segments with a service level access key unique to a service) and the channel level (e.g., by encrypting a second portion of the plurality of segments with a channel level access key unique to a channel associated with the service). On the receiving end, a client device (e.g., a media player) requests a service level access key prior to content acquisition. As such, a client can join any channel on a segment protected with the service level key without waiting for a license for that channel first, and the channel license can be acquired in parallel with the content acquisition during channel switching.

Abstract: Techniques for rapid video on demand (VOD) media content breach response are described. In some embodiments, during content preparation, a server generates an encrypted media content item by generating a first encrypted portion using a first key derived from a first seed that is of a first type and generating a second encrypted portion using a second key derived from a second seed that is of a second type. In some embodiments, the server classifies the first portion in a first category (e.g., a prioritized category) and the second portion in a second category (e.g., a non-prioritized category). During a breach response, the server repairs the encrypted media content item by re-encrypting portions in the first category, e.g., re-encrypting the first encrypted portion using a replacement key derived from a replacement seed that is of the first type, and updating encryption metadata.

Abstract: Techniques for a trusted system for secure content distribution and trusted recording of content consumption are described. In some embodiments, the trusted system transcodes and transcrypts a media content item using a key obtained from a content provider and one or more keys based on an entitlement from a service provider to generate an encrypted media content item. The trusted system further receives a request to provide the media content item to a client device. The trusted system also obtains a signed audit token recording the request upon an authorization by the service provider based on the entitlement and a confirmation by the content provider, where the signed audit token is signed by the content provider and the service provider. The trusted system additionally provides the one or more keys for decrypting the encrypted media content item and reports the signed audit token.

Abstract: In one embodiment, a system is described, having a processor to receive a request for download of a high priority adaptive bitrate (ABR) content item which is available for download at a higher bit rate and a lower bit rate, and a request for a download of a low priority ABR content item, which is also available for download at a higher bit rate and a lower bit rate. A byte acquisition scheduler determines a required bandwidth to download the high priority ABR content item without adapting to the lower bit rate, and determines a remaining bandwidth to download the low priority ABR content item. A download interface interfaces with an ABR server, downloads the high priority ABR content item and the low priority ABR content item, and allocates at least the required bandwidth and up to the remaining bandwidth. Related systems, apparatuses and methods are also described.

Abstract: In one embodiment, a method, system, and apparatus is described in which data is stored in a memory to be used by a processor. The processor performs the steps of allocating initial available bandwidth for adaptive bitrate (ABR) streaming over an ABR streaming network among a set of channels available to be streamed, optimizing at least one profile for at least one channel of the set of channels after the initial available bandwidth has been allocated, the optimizing being performed on the basis of a video quality metric, a viewing metric, and at least one of: a central processing unit (CPU) constraint, and a bandwidth constraint. The allocating and optimizing is repeated upon one of adding at least one channel to the set of channels, deleting at least one channel from the set of channels, changing available CPU capacity, and changing available bandwidth. Related methods, systems, and apparatus is also described.

Abstract: Cache aware streaming may be provided. First, a client device may measure a transfer rate of a flow corresponding to content. The client device may then throttle down the flow to a first encode quality level in response to determining that the measured transfer rate of the flow will not support a current encode quality level of the flow. The first encode quality level may be lower than the current encode quality level. Next, the client device may determine a recommended encode quality level from a response corresponding to the flow. The flow may then be throttled up to the recommended encode quality level by the client device.
