System and method for setting default audio and subtitling language preferences for a video tuner

摘要

The present invention enables automatic setting a natural language default selection in a video presentation device and facilitates easy manufacturing adjustments to accommodate a variety of possible natural language preferences that exist among different geographical areas. A video tuner natural language default selection system of the present invention facilitates reception of video communication signals (e.g., a television broadcast signal) and tuning into particular geographical default natural language information included in the video communication signal. A tuner controller provides instructions to a tuner on the selection of the geographical default natural language information for communication to downstream components. A memory stores information for the tuner controller, including a geographical default natural language indicator for referring to a geographical natural language table comprising natural language selections. In one exemplary implementation the geographical natural language table is configured to comply with IEEE 1394 requirements and is included in an IEEE 1394 compliant AV/C tuner preferred components list descriptor.
