In certain implementations, closed captioning data can be packaged in IP packets and transmitted over an HDMI interface to permit closed captioning data to be rendered at a television set or other HDMI sink closer to the TV set rather than at a source so as to more closely match the capabilities of the display device. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.

Closed captioning services provide textual representation of spoken audio content for the benefit of hearing-impaired viewers, or for anyone desiring such output. When the audio/video content is delivered via a High-Definition Multimedia Interface (HDMI) interface, captioning is rendered by the source rather than the TV (as it was with traditional analog TV). This can create user confusion and varying quality of closed captioning display results.
Certain illustrative embodiments illustrating organization and method of operation, together with objects and advantages may be best understood by reference to the detailed description that follows taken in conjunction with the accompanying drawings in which:
FIG. 1 is an example of an HDMI-connected two-component audio/video (A/V) system consistent with certain embodiments of the present invention.
FIG. 2 is an example of an HDMI connected three-component A/V system consistent with certain embodiments of the present invention.
While this invention is susceptible of embodiment in many different forms, there is shown in the drawings and will herein be described in detail specific embodiments, with the understanding that the present disclosure of such embodiments is to be considered as an example of the principles and not intended to limit the invention to the specific embodiments shown and described. In the description below, like reference numerals are used to describe the same, similar or corresponding parts in the several views of the drawings.
The terms “a” or “an”, as used herein, are defined as one or more than one. The term “plurality”, as used herein, is defined as two or more than two. The term “another”, as used herein, is defined as at least a second or more. The terms “including” and/or “having”, as used herein, are defined as comprising (i.e., open language). The term “coupled”, as used herein, is defined as connected, although not necessarily directly, and not necessarily mechanically. The term “program” or “computer program” or similar terms, as used herein, is defined as a sequence of instructions designed for execution on a computer system. A “program”, or “computer program”, may include a subroutine, a function, a procedure, an object method, an object implementation, in an executable application, an applet, a servlet, a source code, an object code, a shared library/dynamic load library and/or other sequence of instructions designed for execution on a computer system.
The term “program”, as used herein, may also be used in a second context (the above definition being for the first context). In the second context, the term is used in the sense of a “television program”. In this context, the term is used to mean any coherent sequence of audio video content such as those which would be interpreted as and reported in an electronic program guide (EPG) as a single television program, without regard for whether the content is a movie, sporting event, segment of a multi-part series, news broadcast, etc. The term may also be interpreted to encompass commercial spots and other program-like content which may not be reported as a program in an electronic program guide.
