Embodiment Construction

[0022] Hereinafter, the present invention will be described in detail with reference to the accompanying drawings and in conjunction with embodiments. It should be noted that the embodiments in the present application and the features of the embodiments may be combined with each other in the case of no conflict.

[0023] The embodiment of the present invention adopts a multi-cache mechanism (for example, a double-cache mechanism), which is a data processing mechanism that uses space to exchange time, so as to ensure continuous data acquisition (ie, reception) in the case of a large amount of data, thereby improving data analysis. correctness. The following description will be given through specific embodiments.

[0024] like figure 1 Shown is a flowchart of a method for receiving and processing multimedia data, the method comprising the following steps:

[0025] Step S102, when receiving the multimedia data, select the buffer area according to the busy and idle state of the...

Abstract

The invention discloses a multimedia data receiving and processing method and device. The method comprises the steps as follows: when multimedia data are received, cache regions are selected according to busy and free states of the cache regions; at least two cache regions are provided; when data don't exist in each cache region, the state is set to be an free state; the multimedia data are written in a selected cache region; whether the amount of the data written in the cache region exceeds a set full load value is judged, and a storage amount, larger than the full load value, of the cache region is selected; and if the amount of the data written in the cache region exceeds the set full load value, the state of the selected cache region is busy, data in the selected cache region are started and processed, and a next cache region is selected continuously and follow-up multimedia data are written in the cache region. According to the multimedia data receiving and processing method and device, the loss problem of received data in a data processing process is solved.

Description

technical field [0001] The present invention relates to the field of communications, and in particular, to a method and device for receiving and processing multimedia data. Background technique [0002] At present, there are various mobile TV standards and operating networks around the world, such as ISDB-Tmm (Integrated Services Digital Broadcasting-Terrestrial mobile multimedia, Integrated Services Digital Broadcasting-Terrestrial Mobile Media), CMMB (China Mobile Multimedia Broadcasting, China Mobile Multimedia Broadcasting) , DVB-H (Digital Video Broadcasting Handheld, digital video broadcasting for handheld devices), etc., users can use the receiver device integrated in the mobile phone to watch the content of radio and television programs in real time. [0003] ISDB-Tmm has been adopted as one of Japan's nationwide mobile multimedia broadcasting standards. Broadcasting using this standard began on July 24, 2011, the day when analogue TV broadcasting was closed. ISDB-...
