  • Patent number: 8225361
    Abstract: Techniques to remotely monitor and control operations performed by one or more head-ends (or servers) in an information distribution system. In one implementation, a monitor and control unit communicates with various elements (e.g., an IPG service manager and a session manager) within each head-end to receive information relating to the operations of the head-end. This information may include status and/or indications of possible error conditions relating to (1) various operations (e.g., encoding, multiplexing, and so on) performed by the head-end, and (2) the transport streams being transmitted from the head-end. The received information may then be forwarded to one or more remote devices (e.g., pagers, cellular phones, PDAs) designated to receive the information. Response messages may also be received from the remote devices and forwarded to the appropriate head-end, which may adjust its operation as indicated by commands included in the messages.

  • Patent number: 8212927
    Abstract: The present invention relates to a technology of appropriately improving image resolution. According to an image signal processing method of the present invention, an input video signal contains an image signal whose pixel size is converted at a specified magnification scale. The input image signal is used to calculate sampling frequencies for image signals before and after the pixel size conversion. A ratio of sampling frequencies before and after the pixel size conversion is used to determine the specified magnification scale. A sampling phase for the image signal before the pixel size conversion is calculated from the input image signal after the pixel size conversion. A sampling carrier for the image signal before the pixel size conversion is generated from the sampling frequency and the sampling phase both before the pixel size conversion.

  • Patent number: 8199254
    Abstract: In a device for separating a synchronous signal in a video signal, a capacitor receives the video signal to obtain a coupling signal, a level determining circuit receives the coupling signal and compares a voltage level of the coupling signal with a number of reference voltages. The reference voltages define several reference voltage ranges, one of which is a predetermined reference voltage range. The level determining circuit outputs an adjusting signal according to a reference voltage range corresponding to a minimum voltage level of the coupling signal within a predetermined time period. A level adjusting circuit has several current sources for receiving the adjusting signal and thus controls the current sources to adjust a DC level of the coupling signal. A synchronous signal separating circuit separates the synchronous signal from the coupling signal when the minimum voltage level of the coupling signal is substantially within the predetermined reference voltage range.

  • Patent number: 8201201
    Abstract: Techniques are described that permit the flexible introduction of branding elements into or around video rendered by a media player. One or more sets of metadata related to the presentation of branding elements may be collected, and then one or more sets of the metadata may be selected based on business rules when the media player requests a particular piece of content. The selected metadata may indicate what branding element is to be displayed, and how it is to be displayed (e.g., position of element in video rendering window). The media player is then instructed based on the metadata to access and appropriately place the branding elements in or outside of the video rendering window (e.g., overlayed on top of the video content).

  • Patent number: 8201196
    Abstract: SMS messages are conveyed via a TV communication infrastructure for receipt by a TV set-top box having a unique ID. The SMS messages are sent by a cellular telephone to a cellular service provider and are encoded with a unique ID of a destination TV subscriber's TV set-top box so as to be identifiable as destined for the TV communication infrastructure. After identifying that an SMS message is destined for the TV communication infrastructure, the cellular service provider forwards the SMS message to a TV communication gateway, which processes the SMS message, including identifying the unique ID of the TV subscriber's TV set-top box, and forwards data relating to the SMS message to the TV subscriber's TV set-top box.

  • Patent number: 8191093
    Abstract: The present invention provides methods and systems for accessing services in a television system. In one embodiment, a DHCT presents a subscriber an EPG presentation containing a plurality of selectable bi-directional services that are purchasable for a period of time and rendered to a buying subscriber on an individualized basis as offered by the cable television system. The subscriber navigates an EPG menu presentation with an input device such as a remote control device and selects a purchasable service by choosing the visual representation that corresponds to the desired service. The DHCT receives the user input, translates the selected command into an executable program call that queries service availability and, if the service is available, initiates the selected bi-directional audiovisual service on a personalized session.
