摘要:
A digital and analog television signal digitization and processing device that performs the digitization and processing functions using a common reference frequency source that is used to generate multiple subclock signals, wherein the reference frequency source is independent of any synchronizing characteristic of the input signal. For dual channel analog signal processing, the common frequency source is not locked to either channel/input signal. Digital signal processing is accomplished based on the same common reference frequency source. Advantageously, the present invention allows all of the analog-to-digital converters and decoder circuitry/logic necessary for simultaneously digitizing and processing several analog and digital television signals to be integrated on a single integrated circuit as well as eliminating duplicate frequency generation circuits.

An apparatus such as a television signal receiver controls an external device such as a digital recording/reproduction device via a digital data bus by remapping keys on a user input device. According to an exemplary embodiment, the apparatus includes an input/output terminal operative to enable signal transfer between the television signal receiver and an external device via a digital data bus. A processor is operative to detect a first command signal of a first control protocol from a user input device, and to detect one of first and second modes of the television signal receiver. The processor detects the first mode in response to making a connection between the television signal receiver and the external device via the digital data bus, and detects the second mode in response to terminating the connection between the television signal receiver and the external device via the digital data bus. The processor enables the input/output terminal to output a second command signal of a second control protocol to the external device via the digital data bus responsive to the first command signal if the first mode is detected. The processor enables a function of the television signal receiver responsive to the first command signal without enabling output of the second command signal to the external device if the second mode is detected.

A combined de-interlacing and frame doubling system (114, 114′ and 114″) advantageously serves to de-interlace successive lines of Present Field Video data at twice the field rate to yield an output bit stream suitable for display on display device that utilizes progressive scanning. The de-interlacing and frame doubling system in accordance with present principles includes a frame memory mechanism (116, 116′ and 116″) for storing at least one frame of interlaced video having a prescribed field rate. At least one de-interlacing circuit (11401, 1140′1, 1140″) pulls at least two fields of video data from the memory mechanism at a rate of at least twice the field rate for performing a full de-interlacing function in half of a field period to generate the a progressive, frame doubled signal for receipt at the display device.

A system as described herein enables a user to access auxiliary information when viewing an enhanced performance television signal or program. Particularly, a television signal system is operative, configured, and/or enabled to allow a user to access and/or utilize auxiliary information when viewing a high definition or progressive-scan television signal. Briefly, an exemplary television signal system receives the auxiliary information/data (e.g. closed caption data) on a selected interlaced standard definition input, processes the auxiliary data, and combines or overlays the auxiliary data with a television (video) signal received on a selected input that does not have its own embedded auxiliary information/data. More particularly, an exemplary television signal system such as described herein involves using closed caption (CC) data from a standard definition signal, processing the CC data, and overlaying the CC data at a video rate of a higher definition signal selected for viewing that does not carry its own embedded closed caption data.

There is provided a method for indicating whether a program is capable of being fully recorded in a remaining storage space on a storage device. An on screen display device is configured as a grid having a first axis and a second axis. The first axis is for identifying the programming selections and the second axis is for identifying the respective broadcast times of the programming selections. Any of the programming selections currently capable of being fully recorded in the remaining storage space on the storage device are identified on the grid using a first distinctive visual identifier. Any of the programming selections that are currently incapable of being fully recorded in the remaining storage space on the storage device are identified on the grid using a second distinctive visual identifier.

There is provided a system and method for channel selection. An exemplary method comprises receiving a channel scan rate command signal that indicates a first channel scan rate or a second channel scan rate. The exemplary method further comprises scanning through a user interface display of a channel list at the first channel scan rate if the first channel scan rate is indicated by the channel scan rate command signal and scanning through the user interface display of the channel list at the second channel scan rate if the second channel scan rate is indicated by the channel scan rate command signal.
