Abstract: A video transmitter comprising a plurality of encoders may be operable to determine, for a transport stream, a constant overall number of bits per time interval corresponding to a frame in the transport stream. For each time interval corresponding to a start and an end of encoding of each of frames using each of the encoders, the video transmitter may allocate a target number of bits to each of the frames to achieve the constant overall number of bits. The allocation of the target number of bits may be based on frame types of the frames and CODEC types of the encoders, where the allocated target number of bits for each of the frames meets buffer overflow/underflow requirements associated with each of the encoders. A quantization parameter (QP) may be calculated and adjusted at each of one or more layers for generating an actual number of bits during encoding.

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: 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: A system for transcoding locally cached content may include a memory configured to store at least a video stream. A controller communicatively coupled to the memory may be configured to determine a video definition format of a requested video stream and compare the requested video stream with a video definition format of a cached version of the requested video stream. A transcoder coupled to the controller may be configured to convert the cached version of the requested video stream to a lower video definition format if the video definition format of the cached version is determined to be higher than the video definition format of the requested video stream. If the video definition format of the requested video stream is same as the video definition format of the cached version, the controller may supply the requested video stream using the cached version stored in the memory without transcoding.
