PROVISIONAL LOAD SHARING BUFFER FOR REDUCING HARD DISK DRIVE (HDD) ACTIVITY AND IMPROVING RELIABILITY AND LIFETIME |
摘要 |
<p>The present invention is directed towards reducing hard disk drive (HDD) activity by sharing the buffering activity between a provisional load sharing buffer (PLSB) and a time shift buffer (TSB). The HDD may be included in a digital host communications terminal (DHCT). Initially, the PLSB buffers initial streaming programs to accommodate for channel changes. Additionally, the streaming program is buffered in a standard definition quality regardless of the format of a connected television. Once a predetermined time has passed determined by the size of the PLSB without a channel change, the TSB begins buffering the streaming program. The TSB can then switch between buffering a high definition quality to a standard definition quality of a streaming high definition program depending on other factors to further decrease the HDD activity. Additionally, the TSB can be disabled to prevent buffering of the streaming program.</p> |
