In the embodiment of the present invention, in order to compress the video of the second program, before displaying the picture of the second program in the sub-picture area, it further includes: extracting each key frame of the video stream data of the channel of the second program, extracting In the key frame, the pixel located at the intersection point of the integer multiple of N rows and the integer multiple of columns generates a new reduced image of one N*N of the original size, where the integer N is rounded up from the ratio of the main picture to the sub picture, so that Compression of the video of the second program may be achieved.
4、本发明实施例中，为了减少视频流文件在实际传输中所占带宽，以及存储所占的空间，会将视频流文件按照一定的压缩算法压缩后再通过解码在画面上进行播放，从而可以减少视频流文件在实际传输中所占带宽，以及存储所占的空间。4. In the embodiment of the present invention, in order to reduce the bandwidth occupied by video stream files in actual transmission and the space occupied by storage, the video stream files will be compressed according to a certain compression algorithm and then played on the screen through decoding, so that It can reduce the bandwidth occupied by video streaming files in actual transmission and the space occupied by storage.
5、本发明实施例中，由于提取第二节目的频道的视频流数据的每一个关键帧，抽取关键帧中位于N的整数倍行和整数倍列的交汇点的像素生成新的原始尺寸的N*N分之一的缩小图像，其中整数N为主画面与子画面比例向上取整所得，从而可以根据主画面与子画面的比例对子画面的视频进行缩放。5. In the embodiment of the present invention, since each key frame of the video stream data of the channel of the second program is extracted, the pixels at the intersection of the integer multiple rows and the integer multiple columns in the key frame are extracted to generate a new original size A reduced image of 1/N*N, where the integer N is obtained by rounding up the ratio of the main picture to the sub-picture, so that the video of the sub-picture can be scaled according to the ratio of the main picture to the sub-picture.
最后需要说明的是：以上所述仅为本发明的较佳实施例，仅用于说明本发明的技术方案，并非用于限定本发明的保护范围。凡在本发明的精神和原则之内所做的任何修改、等同替换、改进等，均包含在本发明的保护范围内。Finally, it should be noted that the above descriptions are only preferred embodiments of the present invention, and are only used to illustrate the technical solution of the present invention, and are not used to limit the protection scope of the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present invention are included in the protection scope of the present invention.
