  • Patent number: 10230812
    Abstract: A set of transcoding techniques are described for transcoding or otherwise processing content, such as media content that includes textual information (e.g., subtitles), to implement subtitles container conversion from one streaming media format to another, with the ability to combine and split input subtitle segments to create subtitle streams of differing lengths with minimal processing overhead. A copy of textual information is stored at a content delivery network (CDN) point-of-presence (POP) server, network edge server device, or other device. When a device requests the content, the CDN POP server determines the type of device based on the information contained in the request and transcodes the textual information substantially in real-time into the correct encoding for that particular type of device when providing the textual information to the device.

  • Patent number: 8817183
    Abstract: This invention relates to a device and a method of generating a first and a second fingerprint (102,104) usable for synchronisation of at least two signals (101,103) and corresponding method and device for synchronising two or more signals. A fingerprint pair is generated on the basis of a segment of a first signal e.g. an audio signal and of a segment of a second signal e.g. a video signal at each synchronisation time point. The generated fingerprint pair(s) are stored in a database (203) and communicated or distributed to a synchronisation device (303). During synchronisation, fingerprint(s) of the audio signal and fingerprint(s) of the video signal to be synchronised are generated and matched against fingerprints in the database. When a match is found, the fingerprints also determine the synchronisation time point, which is used to synchronise the two signals. In this way, a simple, reliable and efficient way of synchronising at least two signals is obtained.

  • Patent number: 8792054
    Abstract: A method, apparatus and computer program for displaying video and accompanying text data on a display are provided. The method includes receiving media content that includes video and determining whether text data associated with the video is to be presented on the display alongside the video. If associated text data is not to be presented, then the video content is output as normal, with the video content occupying a first area of the display (such as the entire display). If associated text data is to be presented, then the video output is automatically resized such that the video occupies a smaller area of the display, and the associated text data is automatically displayed alongside the video. By allowing for dynamic resizing it is possible to display subtitles or closed captions alongside portions of video content without obscuring the video.

  • Patent number: 8774601
    Abstract: A method and apparatus for detecting copy protection included in an input video signal is described. Two types of copy protection are particularly addressed, including techniques that imbed copy protection pulses and copy protection phase flips in the video signal. A method for preserving copy protection is also presented, where the input video signal is first examined to determine if copy protection has been included in the input video signal. The input video signal then converted to component video data, which removes any copy protection present. An output video signal is then generated from the component video data, and when it was determined that the input video signal includes copy protection, the copy protection is recreated in the output video signal.

    Abstract: A system for filtering a digital signal transmitted in a protocol featuring multi-level packetization from a first server to a second server. The first server is coupled to the second server via a one-way data link. The system includes a filter having an input for receiving the digital signal and an output. The filter is configured to analyze the digital video signal and determine whether the digital signal violates one or more predetermined criteria. The filter may be within the first server, or alternatively, within the second server. The predetermined criteria may be unauthorized security level information included within metadata transmitted with the digital video signal. The predetermined criteria may also be format information that, when not conformed to, indicates potential malware or other bad content included within the digital video signal. The filter provides low data transfer latency and/or decoupling of data filter latency from data transfer latency.

  • Patent number: RE45044
    Abstract: Advertising is marked with a code in a way which makes it difficult to fool the system. The advertising is marked with a code at the time the advertising is produced. Then, when the advertising is broadcast, the code on the advertising is analyzed. Different security measures can be used, including producing the code in the closed captioning so that many different people can see the code, or comparing codes in one part of the signal with a code in another part of the signal. Measures are taken to prevent the code from being used to detect commercials. According to another part of this system, a paradigm for a clearinghouse is disclosed in which the user signs up with the clearinghouse, obtains a line of credit, and the advertiser, the agency, and the ad producer also subscribe to the service. When the ad is actually aired, the payment can be automatically transferred.
