摘要
井下电视应用一直受到传输速率的影响,数字井下电视可以分析并解决井下复杂状况问题。采用H.264编码技术可以在相同带宽传输更高的图像质量,以及采用单对线高速数字用户线(SHDSL)技术可以解决井下传输距离与速率相矛盾的问题。该传输技术具备自适应能力来适应同轴铠甲电缆,对传输介质降低了要求且节省成本。通过以上两种技术可以解决井下图像传输距离短和分辨率低的问题,并提高井下数据传输速率。
The application of downhole video has been affected by the transmission rate, digital downhole video can analyze and solve complicat- ed situation in the downhole. The H. 264 coding technology can transport higher quality image in the same bandwidth, and single-pair high speed digital subscriber line （SHDSL） technology can solve the contradictory of transmission distance and rate. The transmission technology has adaptive ability to adapt to the coaxial cable armor, to reduce the demand and save the cost of transmission medium. Through the above two kinds of technology, the problem of low resolution and short transmission distance can be solved, and the downhole data transmission rate is im- proved.
