Embodiment Construction

[0042] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0043] The core idea of ​​the present invention is to establish a data buffer to cache the data sent by the network side, and adjust the data volume and control data in the data buffer in time when the data volume of the data buffer reaches a threshold due to an abnormal situation in the network traffic to avoid data depletion or overflow in the data buffer.

[0044] see figure 1 , a flow chart of a method for processing video data of an interactive network TV provided by an embodiment of the present invention.

[0045] Step S101, establishing a data buffer.

[0046] A data buffer can be esta...

Abstract

The invention is suitable for the field of digital televisions and provides an interactive-type internet protocol television video data processing method. The method comprises the following steps of: receiving video data transmitted from a network side and carrying out flow control on the video data; and carrying out decoding treatment on a video frame of which the flow is controlled. Compared with the prior art, the invention not only realizes the caching of the video data at a terminal, but also prevents data in a data buffering region from exhausting and overflowing by adopting measures of replicating, discarding and recombining video frames, and the like and ensures that the data buffering region provides the video data for a decoder in a constant speed, thereby being capable of ensuring that an IPTV (Internet Protocol Television) set top box can outputs fluent images and users can view ideal audios and videos.

Description

technical field [0001] The invention belongs to the field of digital television, and in particular relates to an interactive network television video data processing method, system and set-top box. Background technique [0002] IPTV (Internet Protocol TeleVision, Interactive Network Television) is a new emerging technology that uses broadband cable TV network and integrates various technologies such as Internet, multimedia and communication to provide home users with various interactive services including digital TV. TV mode. Both traditional analog cable TV and classic digital TV have the characteristics of frequency division system, timing, and one-way broadcasting. Compared with analog TV, although classic digital TV has many technological innovations, it is only a change in the form of the signal, not How media content is disseminated. Therefore, IPTV is not only different from traditional analog cable TV, but also different from classic digital TV. [0003] In order ...
