    Abstract: The present invention relates to a communication system, a transmitter, a receiver, a communication method, a program, and a communication cable for providing high-speed bidirectional communication while maintaining compatibility. When an HDMI (R) source 71 performs bidirectional IP communication with an HDMI (R) sink 72 using a CEC line 84 and a signal line 141, a switching control unit 121 controls a switch 133 so that, when data is transmitted, the switch 133 selects a constituent signal forming a differential signal output from a converting unit 131 and, when data is transmitted, the switch 133 selects a constituent signal forming a differential signal output from a receiver 82. When bidirectional communication is performed using only the CEC line 84, the switching control unit 121 controls the switch 133 so that the CEC signal output from the HDMI (R) source 71 or the receiver 82 is selected. The present invention is applicable to, for example, HDMI (R).

  • Patent number: 7710434
    Abstract: Image processing in mobile devices is optimized by combining at least two of the color conversion, rotation, and scaling operations. Received images, such as still images or frames of video stream, are subjected to a combined transformation after decoding, where each pixel is color converted (e.g. from YUV to RGB), rotated, and scaled as needed. By combining two or three of the processes into one, read/write operations consuming significant processing and memory resources are reduced enabling processing of higher resolution images and/or power and processing resource savings.

  • Patent number: 7379653
    Abstract: The audio-video synchronization process ensures continuity of displayed AV data. To initialize the process, a transport processor determines whether an occupancy criterion of a buffer storing received audio and video frames has been met. If the criterion is met, the transport processor obtains an initial time stamp value from an initial frame, and a subsequent time stamp value from a subsequent frame. Initial and subsequent parameters are computed from these respective time stamp values, and are compared against each other. If the parameters coincide, the frame is valid, and corresponding audio or video frames may be decoded and displayed. If the parameters do not coincide, a recovery process is initiated. In either event, the invention makes it possible to achieve audio-video synchronization for both live and playback modes of a digital video recorder (DVR).

  • Patent number: 7197164
    Abstract: A digital watermark embedder reduces a watermark signal as a function of time varying properties of video such that a watermark that would otherwise be static over frames is selectively reduced to make it imperceptible. The method computes a watermark signal corresponding to locations within a frame, where the watermark signal is mapped to locations in the video frame and is computed based upon attributes of the video within the frame. The method varies the strength of the watermark signal over time. The process of varying the strength includes reducing the strength of the watermark signal to make the digital watermark less perceptible in the video in locations where the video has time varying properties. The method embeds the watermark signal into the video at the locations with the varying strength.

  • Patent number: 6912008
    Abstract: A method of adding auxiliary data, e.g., audio data, to a high-speed serial video link in such a way that it is invisible to existing receiver and such that auxiliary data, e.g., audio, can be transmitted without any knowledge of the capabilities of the display to receive the auxiliary data. Some of the DC balancing bits are used to transport the auxiliary data information over the link in a manner that does not change the data recovered by a DVI-CE receiver, or a legacy receiver (installed base). DC balancing is also maintained, but with differences over known techniques. Since the auxiliary data bits (which are occupying the time slots of the DC balance bits) will be interpreted by legacy receivers as DC balance bits, the data must be optionally inverted to remain consistent with the value of the auxiliary data bit being transmitted.

  • Patent number: 6370689
    Abstract: An interactive television system for selectively retrieving video images or teletext pages from a remote transmitter (1). User requests are communicated to the transmitter through the telephone network (5). The selected images (e.g., teletext pages) are provided with an image address (a personal teletext page number) and transmitted through a broadcast medium (4). A broadcast receiver (6) captures, stores and displays images having a particular address in a further autonomous manner. In order to prevent co-viewers from tracing the image address and thus watching personal information intended for an individual user on their broadcast receivers (3), the image address is modified whenever a new image is transmitted. Prior to transmitting the image, the address is communicated to the individual user through the telephone network and applied (84,61) to the broadcast receiver.

  • Patent number: 6339449
    Abstract: An additional information signal is superimposed on a video signal at a very low level so that it does not stand out on the reproduced image. Spectral spreading code sequences are generated corresponding to different predetermined parts of the video signal. Bit information signals of the additional information signal made up of plural bits are spectrally spread by the spreading codes to generate spectrally spread bit information signals corresponding to the plural bits. The spectrally spread bit information signals are superimposed on corresponding different predetermined parts of the video signal. Because high priority bit information signals of the spectrally spread additional information signal are superimposed on high priority parts of the video signal, high priority information in the additional information can be protected even if the video signal is modified.

  • Patent number: 6262775
    Abstract: A caption data processing circuit in a decoder is provided for decoding a transport stream (TS). The caption data processing circuit extracts presentation information and caption data from an input transport stream and generates a control signal when the caption data of a one-picture unit has been extracted. A caption decoding portion of the circuit decodes the extracted caption data in response to the control signal. A buffer in the circuit stores the decoded caption data so that the presentation timing of the decoded caption data may be controlled based on the presentation information. As a result, the presentation timing of the picture data and caption data are exactly synchronized, thereby displaying the picture along with its correct caption.

    Abstract: A television receiver for receiving data signals, particularly teletext, associated with a television signal, has a page memory (13) for storing a plurality of pages for display on a display screen. In order to use the memory with maximum effectiveness, a queue is formed in order of priority of requests for allocation of memory locations for storing pages. Various features, such as FASTEXT, TOP, EPG, WST level 2.5, each require a certain minimum number of pages to allow the feature to be achieved. Each feature has a dedicated page request generator (PG-1 to PG-n) which each provide an ordered list of page requests. These page requests are fed to priority setter (P) which allocates for each of the page request generators, a given priority based on a priority scheme (PS) and a list of connected page request generators (PGL). The page request generators (PG-1 to PG-n) react to system events source (S1), broadcast event sources (S2), and/or user event sources (S3).
