  • Patent number: 10271089
    Abstract: Novel tools and techniques are provided for implementing media content streaming or playback, and, more particularly, for implementing media stream synchronization. In some embodiments, a synchronization system might receive a first signal that is output from a first device, which receives an original video signal from a video source and outputs a first video signal. The synchronization system might analyze the first signal to determine a first frame buffer delay, generate a delay adjustment signal based on such determination, and send the delay adjustment signal to a frame buffer delay device. The frame buffer delay device and the first device might concurrently receive the original video signal from the video source. The first delay adjustment signal causes the frame buffer delay device to apply the first frame buffer delay to the original video signal to produce a second video signal that is synchronized with the first video signal.

  • Patent number: 9800824
    Abstract: In order to detect interlace errors in a video signal, one receives successive digitally coded frames, each frame comprising data for a field of a first type and data for a field of a second type (i.e. a top field and bottom field or vice versa). One then generates for each field of the first type:—a first difference signal (D1 F1) representative of the difference between the field and the second-type field of the previous frame;—a second difference signal (D1 F2) representative of the difference between the field and the second-type field of the same frame; and—a third difference signal (D1 F3) representative of the difference between the field and the second-type field of the following frame. Then, in dependence of the values of said difference signals, a decision signal (wOFlag) is generated indicating an estimated temporal relationship of the field to the second-type field of the same frame.

  • Patent number: 8817182
    Abstract: An HDMI® source determines whether or not an HDMI® sink can receive a sub-signal based on VSDB of E-EDID. When the HDMI® sink can receive the sub-signal, the HDMI® source adds a sub-signal to pixel data of a main image composed of pixel data whose number of bits is smaller than that of transmission pixel data transmitted by a transmitter, thereby constructing transmission pixel data. This data is transmitted by the transmitter through TMDS channels #0 to #2. Furthermore, the HDMI® source transmits a general control packet containing sub-signal information indicating whether or not the sub-signal is contained in the transmission pixel data in the control period of a vertical blanking period. The present invention can be applied to, for example, HDMI®.

  • Patent number: 8780276
    Abstract: Methods and apparatus for providing access to program channels, e.g., high definition programs and program channels which corresponding to a standard definition program and/or program channels are described. In accordance with the invention, a high definition auto tune function is supported. When enabled, in one exemplary embodiment, if a user selects a standard program definition channel, a check is automatically made to determine if a corresponding high definition program channel is available. The corresponding high definition program channel is a channel which provides the same program as on the selected standard definition channel but in high definition. When the auto tune function is enabled and a corresponding high definition channel is available, the device, e.g., set to box or tuner implementing the auto tune feature of the present invention, automatically tunes to the high definition channel instead of the standard definition channel.
