摘要： A clock signal generation apparatus includes a first device for extracting reference information from an input digital signal. An oscillator operates for generating a reference clock signal having a frequency depending on a control signal. A second device connected to the first device and the oscillator operates for generating the control signal to the oscillator in response to the reference clock signal generated by the oscillator and the reference information extracted by the first device, and for locking a phase of the reference clock signal to the reference information. A third device connected to the second device operates for deciding whether or not the phase of the reference clock signal is successfully locked to the reference information. A fourth device connected to the second device, a memory, and the third device operates for storing the control signal generated by the second device into the memory when the third device decides that the phase of the reference clock signal is successfully locked to the reference information. A fifth device connected to the memory, the oscillator, and the second device operates for selecting one of the control signal currently generated by the second device and the control signal stored in the memory, and for feeding the selected control signal to the oscillator.

摘要： In an adaptive digital video system, a decoder at a receiving station for a digitally encoded video signal is able to automatically adapt to varying formats and operating modes. All digital video parameters and system operational commands are encoded inband with the digital video serial data stream. The video data is transmitted in successive blocks (e.g., typically an entire image frame or portions thereof) along with system data bytes and control bytes. The data bytes represent the parameters and commands required by the receiver decoder to adapt to the transmitter encoder settings. The control bytes identify the particular parameters and commands represented by respective data bytes. The method is independent of the particular video format or encoding scheme employed, and functions with any transmission medium and bandwidth.

摘要： Systems and methods of a media device are operable to perform a channel change operation. An exemplary embodiment receives a first data table from a data table server, wherein the first data table comprises first control information used to perform a channel change operation such that the media device reconfigures itself to change to a new channel from a currently presenting channel or to a new media content event from a currently presenting media content event. The exemplary embodiment later receives a second data table after initiation of the channel change operation, wherein the second data table is broadcast to the media device in one of a plurality of received broadcasting media content streams that has the new media content event, and wherein the second data table comprises second control information that corresponds to at least some of the first control information used to perform the channel change operation.

摘要： A reception side can easily recognize that metadata is inserted into an audio stream. A container of a predetermined format including an audio stream into which metadata is inserted is transmitted. Identification information indicating that the metadata is inserted into the audio stream is inserted into a layer of the container. At the reception side, it is possible to easily recognize that the metadata is inserted into the audio stream and acquire the metadata reliably without waste by performing the process of extracting the metadata inserted into the audio stream based on the recognition.
