Problems solved by technology

Such excessive and meaningless repetitive operations obviously lead to a waste of system resources and increase the logic complexity of the subtitle linear setting module, so that the cost of UE such as set-top boxes is increased needlessly
[0016] Furthermore, the subtitle display mode control process carried out in a linear flow mode is too fixed, patterned, and lacks flexibility, which is very unfavorable for the development of subtitle display mode control methods

Embodiment Construction

[0054] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0055] The implementation method and device for controlling the subtitle display mode provided by the present invention all need to set priority parameters for the subtitle setting trigger entity that can trigger the subtitle display mode setting process; when the subtitle setting trigger entity sends a subtitle setting event for setting the subtitle display mode When the subtitle setting event is sent, it carries the priority parameter set for itself and the event type representing the subtitle display mode; and, the subtitle setting module receives the subtitle setting event from the subtitle setting trigger entity, reads the subtitle setting event The priority parameter and determine the priority parameter with the highest priority, and then set the subtitle display mode according to the event type included in the subtitle setting event to ...

Abstract

The present invention discloses controlling caption display mode implementation method and device. It contains configuring priority parameter to caption configuration triggering entity which transmitting at least containing priority parameter and event type caption configuration event, caption configuration module receiving caption configuration event from caption configuration triggering entity, reading priority parameter and determine highest priority parameter, caption configuration module according to highest priority parameter caption configuration event inclusive event type configuring caption display mode. Said invented method and device have obvious mobility, capable of effectively avoiding overfull repetitiveness operation.

Description

technical field [0001] The invention relates to the field of multimedia communication, in particular to a method and device for realizing control of subtitle display mode. Background technique [0002] With the development of multimedia communication technology, users can already use user equipment (UE) such as set-top boxes or computers (PCs) to receive communication information from multimedia communication systems to implement multimedia services, such as digital TV services. [0003] The communication information from the multimedia communication system usually includes a subtitle stream; after receiving the subtitle stream, the UE needs to set the display mode of the subtitle stream to ensure that the UE can control the subtitle to be displayed, so that the final displayed subtitle is What the UE wishes to display. For example, the subtitle stream sent to the UE includes a Chinese subtitle stream and an English subtitle stream; after receiving the subtitle stream, the ...
