Abstract:
A STB, communicatively coupled to a server, receives a web page request when, for example, a URI, is entered into a web browser running in the STB. In response, the STB sends a processing assistance request to the server for processing the entire web page regardless of processing capability of the STB. The STB receives processed information resources or contents associated with the entire web page from the server. The server retrieves information resources or contents associated with the entire web page from a web server based on the received processing assistance request. The server determines content type such as video and/or graphics of the retrieved information resources or contents for corresponding content processing. The server determines content formats supported by the STB for content encoding. The STB decodes the resulting encoded information resources or contents from the server to render the entire web page in the STB.
Abstract:
A distributed adaptive bit rate (ABR) proxy system may include a gateway device that includes a first transcoder and is configured to receive segments of a content item from an ABR server, and a secondary device that includes a second transcoder and is configured to receive the segments of the content item from the gateway device. The first transcoder may transcode the segments based at least in part on a first ABR profile to generate first transcoded segments, and the second transcoder may transcode the segments based at least in part on a second ABR profile to generate second transcoded segments. The gateway device may advertise the first and second ABR profiles to user devices and may transmit the first transcoded segments to the user devices in response to requests therefor. The secondary device may transmit the second transcoded segments to the user devices in response to requests therefor.
Abstract:
An apparatus and a system are provided to proxy one or more media signals between at least one local client device and at least one remote client device. For instance, the apparatus can include a first network interface, a rate controller and media transcoder, and a second network interface. The first network interface receives a plurality of media signals over a first communication network, where the plurality of media signals is encoded into at least one codec format. The rate controller and media transcoder transcodes one or more of the plurality of media signals into a different codec format based on channel and processing capabilities associated with one or more local client devices and one or more control messages. The second network interface transmits the one or more of the transcoded plurality of media signals to a respective plurality of remote client devices over a second communication network.
Abstract:
Certain aspects of a method and system for video compression using an iterative encoding algorithm are disclosed. Aspects of a method may include modifying dynamically, a coding rate of at least a portion of received video data based on at least one quantized vector, during bit rate compression of the received video data. At least one of the quantized vectors may be adaptively selected and transmitted to a decoder via a compressed bit stream.
Abstract:
A broadband gateway, which enables communication with a plurality of devices, handles at least one physical layer connection to at least one corresponding network access service provider. The broadband gateway may operate as a home gateway to negotiate with one or more visited gateways, a common authorized service area or domain (ASD) for providing services to the visited gateways. The home gateway may establish one or more corresponding communication links with the visited gateways based on the negotiated common ASD. The home gateway communicates corresponding content for the services to the visited gateways via the established corresponding communication links. The home gateway communicates information about gateway functionalities required for the services to the visited gateways. The visited gateways may port gateway functionalities forwarded by the home gateway, or may perform gateway functionality conversion to support the services, which may be acquired via the home gateway and/or the visited gateways from networks.
Abstract:
One or more methods and systems of indexing an AVC video stream are presented. In one embodiment, the method comprises identifying one or more fields within a picture of an AVC video stream. In one embodiment, a field of the one or more fields indicates the beginning of each picture. In a second embodiment, a field of the one or more fields indicates a picture type of a picture. In a third embodiment, a field of the one or more fields indicates whether a picture is a reference or a non-reference picture. By determining that a picture is a non-reference picture, the picture may be discarded, thereby reducing the memory required to implement the indexing system while increasing the available memory size. In one embodiment, a system of indexing an AVC video stream comprises a control processor, a memory, and a set of instructions resident in the memory.
Abstract:
Aspects of a method and system for customized acquisition of content by a broadband gateway are provided. A broadband gateway may be operable to determine options for acquiring particular content. The broadband gateway may be operable to rank the determined options. The ranking may be based on one or more characteristics of the options and based on user-specified criteria. The broadband gateway may be operable to select one of the options for acquiring the content based on results of the ranking One or more of the options may be available via a first physical layer connection and one or more of the options may be available via a second physical layer connection. The gateway may rank the determined options based on attributes of one or more devices via which the particular content will be consumed.
Abstract:
A broadband gateway, which enables communication with a plurality of devices, handles at least one physical layer connection to at least one corresponding network access service provider. Before allowing the devices to access content from the service provider, the broadband gateway may identify a device power profile for each of the devices, and a network power profile for the content to select a corresponding content delivery mechanism to optimize power consumption. The content may be communicated to the devices utilizing the corresponding selected content delivery mechanism. Depending on configuration, content transcoding may be performed at the broadband gateway and/or at the devices. The content may be burst downloaded and stored in a local storage to be consumed by the devices thereafter. Upon completion of download, the broadband gateway may shut down receiving components to save resources and power. The receiving components may be tuned on to receive additional content when needed.
Abstract:
In an IP multimedia gateway, locations corresponding to communicatively coupled communication devices are determined and transmitted to a service provider device (SPD) that provides services to the communication devices. Communication devices receive location based service profiles from the (SPD) based on the determined locations. Services content from the (SPD) is communicated with the communication devices and/or with the (SPD), based on the profiles. The determined locations are received from communication devices which may be local or remote. A device location map is generated to be displayed by communication devices. The gateway may be integrated in an STB/DTV that displays the determined locations. Content is communicated to communication devices based on their location. The (SPD) may provide content and/or control information for communication device services. Locations are associated with client devices for detecting cloned client devices where determined locations are different than associated locations and/or for restricting services based on location.
Abstract:
Systems and methods to deliver streaming video over a hybrid network are provided herein. An adjusted bitrate to transmit video from a server to a client is determined in response to a fast-forward or rewind request. Frames from a video are selectively transmitted to accommodate for the adjusted bitrate based and a bitrate of a connection between the server and the client.
