  • Publication number: 20140334800
    Abstract: Systems and methods for a self-correcting DVR record pipeline may provider for simpler, lower cost transport producer hardware elements. A free running transport pipeline producer may fill transport buffers without waiting for feedback from the data consumer that data has been completely processed. The pipeline data consumer independently detects transport buffers that are overwritten before processing on the buffer content is complete. The pipeline data consumer drops or deletes any invalid content or stream data to recover from the data overflow condition.

  • Publication number: 20140337411
    Abstract: A method for preparing streaming media content to be rendered by a media player employs a proxy for the media player. The proxy sends a request over a network to a content server. In response, a rolling manifest file is received by the proxy. The manifest file includes a sequence of media segment URLs indicating an ordering of the media segments that create a representation of a portion of the content stream. The URLs follow a predefined naming convention that allows URLs occurring prior to and subsequent to the URLs included in the manifest file to be predicted. The proxy predicts additional URLs that occur prior to and/or subsequent to the URLs included in the manifest file. The manifest file is modified by inserting the additional media segment URLs into the manifest file. The additional URLs are sequentially located before or after the URLs included in the manifest file.

  • Patent number: 8885823
    Abstract: A method for delivering encrypted content to a subscriber terminal on-demand through a communication network is provided. The method begins when SRM receives a request for content from the subscriber terminal. In response to the request, the SRM directs a video server to transmit the content as an unencrypted transport stream to an encryptor. The packets in the unencrypted transport stream include a header with a destination address associated with the subscriber terminal. The encryptor encrypts the content in the unencrypted transport stream to generate an encrypted transport stream. The encryptor also inserts in the packet headers of the packets in the encrypted transport stream the destination address associated with the subscriber terminal obtained from the packet headers in the unencrypted transport stream. Finally, the encrypted transport stream is transmitted to the subscriber terminal over the communication network.

  • Patent number: 8875202
    Abstract: In one embodiment, a method receives packets including video data that was encoded or decoded. The packets are dynamically routed through processing elements in different routes and some of the packets include signatures from processing elements that processed each respective packet. The method then determines a plurality of captures each including a set of packets and determines for each capture, a set of processing elements that processed the set of packets. The set of processing units inserted respective signatures into a user data section of the packets that is defined by a standard used to encode or decode the video data. The determined set of processing elements are analyzed for each capture to determine a processing element in the set of processing elements that is considered to be causing a performance degradation. Then, the method performs a remedial action associated with the processing element.

  • Publication number: 20140314335
    Abstract: A system includes a data storage configured to store a model human visual system, an input module configured to receive an original picture in a video sequence and to receive a reference picture, and a processor. The processor is configured to create a pixel map of the original picture using the model human visual system. A first layer is determined from the pixel map. A weighting map is determined from a motion compensated difference between the original picture and the reference picture. A processed picture is then determined from the original picture using the weighting map and the first layer.

  • Patent number: 8869223
    Abstract: In general, in one aspect, the disclosure describes a resonance restricting material in communication with a bypass line of a cable television tap. The bypass line generates resonances at a defined frequency in response to RF parameters in the tap and the resonances increase insertion losses at the defined frequency and precludes bandwidth of the tap being increased above the defined frequency. The resonance restricting material may attenuate the resonances generated by the bypass line at the defined frequency (e.g., approximately 1.2 GHz) and reduce insertion losses at the defined frequency and enable the bandwidth of the tap to be increased (e.g., from 1.0 GHz to 1.8 GHz).

  • Publication number: 20140307774
    Abstract: A sampling filter process is provided for scalable video coding. The process provides for re-sampling using video data obtained from an encoder or decoder process of a base layer (BL) in a multi-layer system using adaptive phase shifting to improve quality in Scalable High efficiency Video Coding (SHVC). In order to compensate for phase offsets introduced by downsampling an appropriate phase offset adjustment is made for upsampling in SHVC with an appropriate offset included for proper luma/chroma color space positions. In one approach, an adaptive filter is signaled with its phase offset adjusted to account for the luma/chroma offset.

  • Publication number: 20140301488
    Abstract: A method for determining a resampling filter for resampling a video signal used in scalable video coding includes estimating a set of row filters based on a video signal. The video signal has a base resolution that is resampled to provide an output signal that enables more efficient coding of the video signal with an enhanced resolution higher than a base resolution. The set of row filters is applied to the video signal to generate a first output signal having rows that are interpolated to the enhanced resolution. A set of column filters is estimated based on the first output signal for resampling the columns in the video signal. The set of column filters is applied to the first output signal to generate a second output signal having columns as well as rows that are interpolated to the enhanced resolution.
