This is a simple research with transport stream on DVB in Taiwan's channel "CTS". Using the software "TSR" to lead myself understanding the ts and its structure.And it's the Tatung university 's lesson!
In a digital TV structure, multiple TV and radio programs can be transmitted over a common network and share a transmitter by using a technique called multiplexing. A multiplexer combines multiple program streams into a single transmission stream, which is then modulated and transmitted. This allows more efficient use of bandwidth compared to analog transmission, where each program requires a separate transmitter. Digital transmission also provides better reception quality, with the signal either being fully receivable or not, depending on whether the signal power is above a threshold, rather than reception quality gradually degrading with distance as in analog. DVB-T2, the second generation digital TV broadcast standard, further improves bandwidth efficiency and reception quality compared to DVB-T through the use of more advanced
Kernel Recipes 2014 - Writing Code: Keep It Short, Stupid!Anne Nicolas
The traditional KISS principle says that you are stupid if you can’t keep it simple. However, keeping it simple is actually very, very hard. But my lasting impression after reading a lot of code (linux kernel and otherwise) over the years is that there is no excuse for not keeping your code short. And usually, keeping it short is a very good first step towards keeping it simple. This presentation will give some simple tricks and pointers to keep your code short and I will also give some guidelines how to do design and implementation from a high-level point of view. These simple rules should make it easier for you to get your code accepted in open source projects such as the linux kernel.

Over-The-Top (OTT) video delivery uses third-party content delivery networks to stream video over the internet. YouTube is a popular free OTT service, and the proliferation of internet-connected devices has increased complex, multi-screen video consumption. As a result, video delivery is shifting from pay TV operators and set-top boxes to content owners and many different devices. For pay TV operators, OTT poses a threat as subscribers may opt for OTT services instead. To remain relevant, pay TV operators should acquire content, ensure high quality of service, expand beyond set-top boxes with OTT apps, and provide a unified subscription for viewing on multiple devices and screens.
The document discusses the history and current state of climate change research. It notes that scientific consensus has formed around the occurrence of climate change due to human activity like fossil fuel burning. The document warns that climate change poses risks to natural and human systems and that limiting global warming requires substantial reductions in greenhouse gas emissions.
This document provides a summary of two presentations on digital broadcasting switchover:
1) A case study of Turkey's digital switchover project, covering the context, preparation including technology selection and coverage criteria, milestone achievements like measurement campaigns and frequency planning, and generating notification files.
2) A methodology from Ofcom on assessing compatibility between DTT (digital terrestrial television) and LTE networks, involving calculating interference levels, identifying households with over 10% signal degradation near LTE stations, and a filter for better LTE signal rejection.
3) The switchover process requires a holistic government-led approach considering objectives, existing networks and digital network design, not just technical aspects. Compatibility analysis tools were implemented in
This document summarizes research on using DVB-T signals for passive radar ship detection. DVB-T signals provide a large bandwidth and wide coverage suitable for passive radar. Preliminary experiments using a USRP software defined radio were able to detect ships up to 5 nautical miles away departing from a nearby harbor based on the Doppler frequency shifts measured. Future work aims to conduct experiments with cooperative targets and improve the system's range resolution and processing algorithms.
