RESAMPLING FILTERS FOR SCALABLE VIDEO CODING WITH PHASE OFFSET ADJUSTMENT AND SIGNALING OF SAME
Upsampling filters for use in scalable video coding may be selected from a set of filters each with a different phase. In order to accommodate a phase offset introduced from downsampling required to maintain proper luma/chroma color space positions after upsampling, an offset parameter may be used in computing the filter index. Moreover, a different offset may be used for each filter index. These offsets in effect provide a re-mapping of the filter indices. By remapping the filter indices in this manner the performance of the upsampling process can be improved and errors introduced by rounding or which are caused by the finite precision of the process used to compute the filter indices can be taken into account.

ENHANCING TARGETED ADVERTISING IN A HOME NETWORK GATEWAY DEVICE
Advanced set top devices are beginning to merge with home network gateway devices and will soon become the major single entry point into the home. A growing trend and implementation of home gateways is to provide a centralized data entrance point to end user home. Behavioral information may be compiled from each individual device in the home network, and the home network gateway device determines advertisements to insert specifically to each device based on the entirety of the behavioral information compiled from within the home network. The advertisements provided to individual users within the home network may be determined by the home network gateway device, transparent to entities outside the home network. For example, a headend that delivers content to a home network may not know how many devices are connected to a home network gateway device, the type of devices connected, or which devices are receiving content.

As a result, fewer policies need to be drafted, and those few need to be updated less frequently than in previous schemes. Rather than updating the policy itself, the analytical model is automatically updated whenever new data are fed into it. As the analytical model incorporates new observational data, it grows more powerful and thus automatically increases the effectiveness of the high-level policy.

DEVICES AND METHODS FOR MODIFICATIONS OF SYNTAX RELATED TO TRANSFORM SKIP FOR HIGH EFFICIENCY VIDEO CODING (HEVC)
A system for securely authenticating software Application Program Interfaces (APIs) includes a handshake protocol that is provided to validate whether the parties involved are licensed to use the system which includes rights to Intellectual Property (IP) and corresponding obligations. The handshake is a Challenge-Response protocol that includes several steps. First, a Claimant sends a request to a Verifier requesting access to a function through an API. The Verifier reacts to the request by outputting a Challenge that is sent to the Claimant. The Challenge is also retained by the Verifier for use in its internal calculation to verify the Claimant's response. The Claimant next processes the Challenge using components under the license, known as Hook IP, and issues a Response to the Verifier. The Verifier compares the possibly-correct Candidate Response from the Claimant to the known-correct Target Response and if a match occurs the Verifier allows the Claimant access to the API.
IMPROVED ALGORITHMS FOR DETERMINING BITRATE FOR A STATISTICAL MULTIPLEXING SYSTEM TO ACCOUNT FOR SIGNAL COMPLEXITY INCLUDING FILM MODE AND GOP STRUCTURAL CHANGES
A statistical multiplexer (statmux) system for encoding multiple channels of digital television data is provided with improved algorithms for determining bitrate for encoding and decoding to account for signal complexity, including accounting for film mode and GOP structural changes. In film mode when the lower frame per second rate for film mode is identified, rather than faster rate SD or HD modes, instead of determining bit rate from viewing the next picture in the look ahead buffer (LAB), the system looks at a start time stamp for specific data in the LAB. Accounting for GOP structural changes includes identifying the number of pictures (N) between I type pictures in data provided to an encoder and the number of pictures (M) between P type pictures, rather than using a fixed number for N and M.
In one embodiment, a method includes receiving a message from a user client device associated with a user. The message is generated in response to a code being captured by the user client device. A computer system determines a user identifier for a user associated with the user client device based on the message. Also, the computer system determines a control data set based on the message, the control data set including information used to automatically control a set of controllable devices. Then, the computer system automatically makes the control data set available to allow access by a user network device associated with the user identifier. The user network device is configured to download the control data set to automatically allow controlling of the set of controllable devices when connected to the user network device.
While a user views a primary content item (for example, a movie on a television screen), secondary content items are selected and presented to the user, either on the same screen or on a screen of the user's companion device. To choose selections that are relevant to the user's current interests, the selection process considers information beyond the realm of primary and secondary content. Over time, the selection process learns to make more relevant selections by monitoring selection choices made by other systems.

UPSTREAM CHANNEL BONDING PARTIAL SERVICE USING SPECTRUM MANAGEMENT
A method and computing device receives data packets on an upstream bonding group in full service mode, where the upstream bonding group includes a set of channels and each channel has a transmission quality (210). The method detects that a select channel in the set of channels is impaired when the transmission quality of the select channel is below a threshold value (220), and transitions the receiving of the data packets from full service mode to partial service mode by disabling data grant scheduling on the select channel (230). The method monitors the select channel using a spectrum management method while the receiving of the data packets is in partial service mode (240). The method transitions the receiving of the data packets from partial service mode to full service mode when a result from the spectrum management method indicates that the select channel can transmit data packets error free (250).

H04N 21/437 - Interfacing the upstream path of the transmission network, e.g. for transmitting client requests to a VOD server
H04N 21/442 - Monitoring of processes or resources, e.g. detecting the failure of a recording device, monitoring the downstream bandwidth, the number of times a movie has been viewed or the storage space available from the internal hard disk
H04N 7/10 - Adaptations for transmission by electrical cable
A method and apparatus for updating equalization coefficients of an adaptive pre-equalizer of a network element are provided. The method includes monitoring a communications channel to measure distortion of a communications signal received from the network element and detecting whether a transient impairment is present in the communication signal. When a transient impairment is not detected to be present, a pre-equalization coefficient update is transmitted to the network element. However, when a transient impairment is detected to be present, at least selected ones of the pre-equalization coefficients are scaled before the update is transmitted to the network element or the update is withheld from being transmitted to the network element. An apparatus is also disclosed.
