Embodiment Construction

[0013] In this specification and claims, certain terms are used to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use The difference in name is used as a way to distinguish components, but the difference in function of components is used as a criterion for distinction. The "comprising" mentioned in the entire specification and claims is an open term, so it should be interpreted as "Including but not limited to", in addition, the term "coupling" here includes any direct and indirect electrical connection means, therefore, if it is described in the text that the first device is coupled to the second device, it means that the first device can directly and electrically Connect to the second device, or indirectly electrically connect to the second device through other devices or connection means.

[0014] The present invention will becom...

Abstract

The invention provides a data transmission interface device, a transmitter and a method for transmitting multimedia data. The data transmission interface device is communicated with the other data transmission interface device through a digital transmission mechanism used for transmitting multimedia data. The data transmission interface device comprises at least a processor used for processing multimedia data, and a data conversion circuit that is coupled with the processed to convert a plurality of first multimedia datasets into a plurality of second multimedia datasets, and convert a plurality of first auxiliary datasets into a plurality of second auxiliary datasets. The device and method provided by the invention can provide much more information and better video and audio quality for users through the transmitted auxiliary datasets.

Description

[0001] This application is a divisional application of the application No. "200910150707.X" and titled "Data transmission interface device, transmitter and method for transmitting multimedia data" filed with the State Intellectual Property Office on June 22, 2009. technical field [0002] The present invention relates to data transmission and reception, especially to a data transmission interface device, a transmitter and a related method for transmitting and receiving multimedia data through a High Definition Multimedia Interface (HDMI). Background technique [0003] The interval from the last visible scan line of a frame or field to the first visible scan line of the next frame or field is defined as the vertical blanking interval (Vertical Blanking Interval, VBI), and the data transferred during this period will not be displayed on the screen. Taking the analog TV system as an example, the vertical blanking interval can be used to carry additional information, such as ver...
