Television multi-signal parallel processing method and device and television sub-device selection

Abstract

The invention relates to the field of smart televisions, in particular to a television multi-signal parallel processing method and device and television sub-device selection. The television multi-signal parallel processing method comprises: defining a respective device route node for each sub-device; distributing required sub-device resources for each parallel signal processing by establishing a connection access between the device route nodes; if there is no signal processing required resource node in a matrix channel, determining that distribution of corresponding sub-devices fails, if there is a resource node, polling a target node queue, if there is an idle target node meeting connection rules, determining that distribution of the corresponding sub-devices succeeds, if the distribution of all the sub-devices in resources required by single signal processing succeeds, determining that resource distribution for signal processing succeeds, and determining that the resource distribution fails if not; executing all parallel signal processing with successful resource distribution; therefore, maximum parallel execution, quick switching and dynamic adaptive hardware configuration are achieved.

Description

technical field [0001] The invention relates to the field of smart televisions, in particular to a method, equipment and sub-equipment selection for improving the efficiency of parallel processing of multi-channel signals. Background technique [0002] With the integration of telecommunications network, computer network and cable TV network, smart TVs need to process various media signals including broadcast TV streams, network streaming media or local media, so as to provide users with high-definition TV and digital audio programs. , high-speed data access, and picture-in-picture, TV program playback and recording and other information processing and display. Some smart TV information processing needs to be executed at the same time to achieve the best user experience. For example, picture-in-picture, TV program broadcasting and recording coexist, and traditional TV broadcasting and Internet broadcasting coexist. [0003] Usually a TV media playback, including broadcast T...

AI Technical Summary

Problems solved by technology

[0006] 1. Hardware modules such as decoding already support multi-channel, but software (TV middleware) does not support it, because the workload of software reconstruction is very large

[0007] 2. In the case of resource conflicts on the hardware, resource switching is too slow

[0008] 3. The versatility and adaptability of the software are too poor. Different hardware configurations require a lot of software work to adapt, and the flexibility is poor

[0009] Therefore, it is necessary to establish a method for improving parallel execution, fast switching, and dynamically adapting hardware configuration to solve the design limitations of traditional TV architecture solutions in the use of smart TVs, and to adapt to the constantly updated signal processing requirements and hardware evolution. need
