Abstract: An apparatus includes a transmitter configured to broadcast data to a plurality of receivers is provided. A control circuit is configured to arrange the transmitter to broadcast the data based on a protocol and to arrange the transmitter to broadcast a subset of the data in response to a request from one of the plurality of receivers. In another aspect, a method for operating a broadcast interface is provided. The method includes broadcasting data to a plurality of receivers based on a protocol and broadcasting a subset of the data in response to a request from one of the plurality of receivers. Another apparatus is provided which includes means for broadcasting data to the plurality of receivers based on a protocol and means for arranging the means for broadcasting to broadcast a subset of the data in response to a request from one of the plurality of receivers.

Abstract: A method, a video processing system, and an electronic device are disclosed. A video transcoder may decode a compressed video data frame creating a decoded video data frame. The video transcoder may embed a network presentation timestamp in the decoded video data frame. The video transcoder may re-encode the decoded video data frame creating a transcoded video data frame. A field programmable gate array may compare the network presentation timestamp with a transcoder presentation timestamp to determine a timestamp offset.

Abstract: Caption data incorporated in an input coded bit stream conveying a video service is processed by recovering the caption data from the input coded bit stream, decoding the input coded bit stream to form a digital video signal composed of a sequence of frames, embedding the caption data in an ancillary data space of the digital video signal, and encoding the digital video signal to produce an output coded bit stream incorporating the caption data.
