Abstract: A device includes a key store memory, a rule set memory, a plurality of cryptographic clients, and a key store arbitration module. The key store memory stores a plurality of cryptographic keys and the rule set memory stores a set of rules for accessing the cryptographic keys. A cryptographic client is operable to issue a request to access a cryptographic key(s) and, when access to the cryptographic key is granted, execute a cryptographic function regarding at least a portion of the cryptographic key to produce a cryptographic result. The key store arbitration module is operable to determine whether the request to access the cryptographic key is valid; when the request is valid, interpret the request to produce an interpreted request; access the rule set memory based on the interpreted request to retrieve a rule of the set of rules; and grant access to the cryptographic key in accordance with the rule.

Abstract: A method and apparatus for distributing video-on-demand loading include processing that begins by receiving a concurrent additional request for accessing a video program (i.e., while the server associated with the video program is processing one request for access to the video program another is received). The processing continues by providing the video program to a 2nd server in response to the concurrent additional request. The 2nd server causes the video program to be stored in the redundant array of independent disks (2nd RAID) associated with the 2nd server. The 2nd server processes the concurrent additional request via the 2nd RAID such that processing of multiple requests for the same video program is distributed throughout the video on demand system.

Abstract: A method includes storing, at a storage location of a system, a first security value and utilizing, at the system, a first security certificate compatible with the first security value and incompatible with at least a second security value, wherein the first security certificate enables one or more processing features of the system in conjunction with the first security value. The method also includes receiving a certificate revocation stimulus and modifying a value at a first bit position of the storage location so as to convert the first security value stored at the storage location to the second security value. Another method includes receiving multimedia data at a system, wherein the multimedia data is representative of multimedia content including a digital watermark representing one or more system identifiers, and disabling at least one processing feature if the system identifiers includes a unique identifier associated with the system.

Abstract: A method and apparatus for processing overlay data in a multimedia system include processing that begins when the server of the multimedia system selects a set of channels from a plurality of channels based on a set of channel select signals. The processing continues as the server converts the set of channels into streams of channel data. The server then decodes the streams of channel data into video frames for each channel of the set of channels. The processing continues as the server generates overlay data for at least one channel based on an overlay selection input, which is provided by the client that requested the particular channel. The processing then continues as the server encodes the overlay data with video frames of at least one channel to produce channel overlay packets. The processing continues as the server encodes the video frames of the other channels into sets of channels to produce channel packets.

Abstract: A processing system includes an interface for receiving application data at the processing system corresponding to an application, the application data including authentication data. A one-time programmable memory stores at least one application key. A processing module executes an operating system that includes a security routine to authenticate the application data based on the authentication data and the at least one application key. The security routine permits the execution of the application by the processing module when the authentication data is authenticated, and prevents the execution of the application by the processing system when the authentication data is not authenticated.

Abstract: A method and apparatus for controlling access to a video system based on bandwidth consumption include processing that begins as the server monitors bandwidth utilization of connections within the video system. The processing continues when the server receives a request to access a video program via the connection from a client device of the video system. The processing then continues as the server determines whether determine whether the client device has subscribed to receive the video program at the first quality level. When the client device has not subscribed to receive the video program at the first quality level, the video quality of the video program is converted from the first quality level to a video quality subscribed to by the client device.

Abstract: An encoding system includes a first signal interface for receiving a first video signal in a first format. A second signal interface receives a second video signal in a second format. A first encoding module generates a first processed video signal in a third format. A second encoding module generates a second processed video signal in a fourth format, wherein the second processed signal is generated contemporaneously with the first processed video signal and wherein the first format differs from the third format and the second format differs from the fourth format.

Abstract: A watermarking module can be used in a video encoding system that processes a video signal. A watermark data module generates original watermark data based on either non-watermark data that is based on the video signal and or that includes a codeword associated with a scrambling of content included in the video signal. A watermark generation module generates a watermarked video signal in accordance with the original watermark data.

Abstract: A watermarking module can be used in a video encoding system that processes a video signal. A watermark recovery module generates recovered watermark data based on watermark data from the video signal. A watermark generation module generates a watermarked video signal in accordance with the recovered watermark data.

Abstract: A method and apparatus for distributed load multiplexing of multiple encoded signals over a shared communication path include processing that begins by receiving a 1st encoded signal having a 1st varying relative bit rate. The processing continues by receiving a 2nd encoded signal having a 2nd varying relative bit rate. For example, the 1st and 2nd encoded signals may be an MPEG encoded signal including a plurality of I frames, B frames and P frames. The processing continues by aligning multiplexing of the 1st and 2nd encoded signals based on reducing cumulative peak bit rates of the 1st varying relative bit rate and the 2nd varying relative bit rate. For example, the 2nd encoded signal may be delayed via buffering to ensure that the I frames of the 1st and 2nd encoded signals are misaligned.
