  • Patent number: 8997136
    Abstract: Methods and apparatus for providing packetized content to users via a bandwidth-optimized network. In one embodiment, legacy and IPTV streams are carried over the same switched digital infrastructure, and freely intermixed without regard to their encoding or type. A user's selection for IPTV content is transmitted to an IP proxy (such as a gateway apparatus or a headend server), then on to the switched digital server which causes provision of the requested content back to the proxy for formatting. The formatted content is then delivered to the requesting IP-capable device. The entire carrier class program stream is therefore available as IP-encapsulated content to the IP capable devices (and as legacy content to legacy devices) without any significant modifications to the network infrastructure or bandwidth penalty.

    Abstract: A system and method that provide reduced latency in a video signal processing system. Various aspects of the present invention may comprise receiving a current request from a user for first video information. Such a request may, for example, be received with a user interface module. A first video stream and a second video stream may be received simultaneously, where the first video stream comprises the first video information currently requested by the user, and the second video stream comprises second video information not currently requested by the user. A video receiver module may, for example, perform such receiving. The first video stream may be processed to present the first video information to the user at the current time. Further, the second video stream may be pre-processed in preparation for being presented to the user in the future. A video processing module may, for example, perform such video stream processing.

  • Patent number: 8978058
    Abstract: A placeshifting device handles content from a media source (e.g., a set-top box) that might incorporate a form of copy-protection such as HDCP. In one case, when a placeshifting mode is entered (as opposed to a pass-through mode), the copy-protection capability of the interface (e.g., an HDMI interface) is simply disabled. In another case in which the media source includes a copy protection “flag” or the like that can be interrogated by the placeshifting device, the placeshifting device determines whether the media source copy-protection is enabled, and only then disables the copy-protection capability of the interface. In another case in which selectable output control (SOC) is available in the media source, the placeshifting device determines whether alternate interfaces are available (e.g., component video, composite video, and the like), and if so, disables the interface having copy-protection capability.

    Abstract: The invention proposes a system for reading digital content comprising:—a device for access to a computer network;—a device for reading digital content able to communicate with the device for access to a computer network via a connection interface, and adapted for implementing at least one software application, and—an access control module able to encrypt or decrypt digital streams, the access control module being associated with the device for reading digital content and connected to the device for access to a computer network, in which the digital application or applications of the reading device communicate with the access control module via the network access device, and said communication is implemented by means of server software hosted by the access control module or the access device. The invention furthermore proposes a method of reading a digital content implemented by the system.

  • Publication number: 20140380352
    Abstract: A process to enable trick play operations is provided for HLS streaming video that has been converted by a system from DTCP. The system server provides a modified SEEK operation when an HLS GET message is received from an HLS client player. For the process, a DLNA header is provided from the HLS client player by including it in the HLS GET message. The HLS client also provides a DLNA RANGE REQUEST that requests a range of chunks making up a video desired and a seek point from where a seek operation is needed. The HLS server recognizes the DLNA header of the HLS GET message and DLNA RANGE REQUEST and obtains a range of chunks making up an extent of the recorded video using metadata fields. The server then generates a new HLS playlist with identification of the chunks and keytag corresponding to the seek operation. The server will provide chunks from the seek point and a rolling playlist to identify chunks and keytag from the seek point.

  • Publication number: 20140373042
    Abstract: Method and system to prevent control words sharing. The system comprises a receiver capable of processing a digital data stream. The receiver, having a video descrambler device, is coupled to a primary and secondary secure device. The digital data stream comprises video content data scrambled by a first algorithm using a control word, audio content data encrypted with a secret second algorithm using a system key, and encrypted control messages comprising the control word. The primary secure device decrypts the control message and obtains the control word. The video descrambler device uses this control word to descramble the video content data. The secondary secure device comprises a decryption device which decrypts the encrypted audio content data and a watermarking module configured to add a watermark to the decrypted audio content data and return watermarked decrypted audio content data to the receiver.

  • Patent number: 8914823
    Abstract: Provided are an apparatus and method for restricting A/V listening and viewing using parental levels. According to an embodiment of the present invention, a parental level detected from a video signal is compared with a level set by a user, and previously buffered video and audio are repeatedly output if the detected parental level is higher than the level set by the user. The parental level is included and transmitted in a video line of a broadcast signal. Also, the repeatedly output video is a still image or a moving image, and the repeatedly output audio is audio between two audio mute periods finally detected. Accordingly, there is no case when a user waits for nothing while viewing a black screen in a mute state, while a parental lock operation is performed.

  • Publication number: 20140351848
    Abstract: A method and cryptographic system for descrambling content packets, included within a digital transport stream, having conditional access messages and header data. The method and system require a deciphering algorithm, processed by a descrambler of a multimedia unit, using an initialization vector as a first input and a control word as a second input. The multimedia unit is connectable to a security module for processing the conditional access messages and extracting control words therefrom. The initialization vector, or intermediate data to determine the initialization vector, is the result of a cryptographic function based on at least one variable extracted from the digital transport stream and processed by the security module.

  • Publication number: 20140344851
    Abstract: A method for determining an identifier of a conditional access card used in a conditional access system, in which the conditional access card autonomously modulates the timing of data packets sent by the conditional access card, according to a sequence that depends on the identifier of the card. The sequence is generated by a predefined non-linear function stored on the conditional access card, and the predefined non-linear function depends on both the identifier of the conditional access card and a non-linear random sequence that is known to the conditional access card and a monitoring station that receives transmissions from the conditional access card.

  • Publication number: 20140344850
    Abstract: A plurality of sets of primary product keys is established or generated, each set containing at least two different primary product keys. One primary product key of each set is made available to each receiver or group of receivers, such that each receiver or group of receivers is provided with a different combination of said primary product keys. For each set of primary product keys, the plurality of receivers or groups of receivers is provided with a different primary entitlement control message corresponding to each primary product key of said set, each such primary entitlement control message distributing a primary control word for recovery through decryption using the corresponding primary product key. The primary control words can then be used for purposes such as tracing compromise of the conditional access system, or arranging for differently fingerprinted content to be decoded at different receivers or groups of receivers.
