Embodiment Construction

[0015] First refer to figure 1 , the system 10 includes a source 12 of multimedia, such as a set-top box, and a sink device 14 for displaying the multimedia, such as a digital TV (DTV), but the source 12 could be provided by other sources, such as a satellite receiver or a device for receiving video over IP. Internet interface), and receiving device 14 may be realized by, for example, a game console, video disc player, digital clock radio, mobile phone, personal digital assistant, and the like.

[0016] like figure 1 In particular, when source 12 is configured as a set-top box, source 12 includes a portable lightweight plastic housing 16 that houses a digital source processor 18 . Source processor 18 receives from receiver 20 a TV signal comprising a video signal having CC data representing closed caption (CC) text. In a non-limiting example, TV tuner 22 may be controlled by source processor 18 to cause only TV signals on tuned channels to be transmitted to source processor ...

Abstract

Closed caption (CC) data is carried across a digital interface (24, 28) such as HDMI by a source (12) such as a set top box arrange CC data into a HDMI packet that is then transmitted, along with video packets, across the interface to a sink (14) such as a TV. The CC data is kept in the same format that it was received and the TV's decoder processor processes the packets and renders CC text as if the CC data had been received by the tuner (34) of the TV.

Description

technical field [0001] The present application generally relates to the use of packets to communicate closed captioning data over a digital interface such as High Definition Multimedia Interface (HDMI). Background technique [0002] In analog TV, closed caption (CC) text is transmitted within the TV signal, and the CC text is processed and displayed on the TV. This means: a viewer can use a TV remote control (RC) to establish CC settings such as "on" or "off" and other CC related settings. [0003] However, with the advent of digital TV (DTV), there is currently no protocol for linking a multimedia source (such as a set-top box) with a multimedia sink device (such as a DTV) in a manner that would allow a TV RC to be used to establish a CC setup. A method of transferring CC data between digital interfaces such as, for example, HDMI. Instead, the source has to integrate the CC data into the TV signal before sending it to the receiving device, which means it has to communicat...
