The Answer is To provide channel surfing capabilities with a fixed bandwidth and a constraint of not exceeding a one-second delay in video decoding, you would need to implement a system that is optimized for quick tuning and fast data transmission. Here are some strategies that could be employed to achieve this:

1. **Use Efficient Video Compression**: Employ modern video compression standards like H.264 or H.265, which provide high-quality video at lower bitrates. This will reduce the amount of data that needs to be transmitted over the channel, allowing for quicker changes between channels.

2. **Implement Fast Channel Switching Techniques**: Techniques such as Rapid Channel Zapping or Fast Channel Change (FCC) can be used. These methods pre-fetch a small portion of the next channels in the lineup, allowing for a quick display of video when the user switches channels.

3. **Buffering Strategy**: Implement a smart buffering strategy that pre-buffers a few seconds of video for adjacent channels. This allows for almost instantaneous display of video when the user switches channels, as the pre-buffered content can be played while the decoder begins processing the new channel's stream.

4. **Multicast Streaming**: If the system supports multicast, use it to send the same stream to multiple users. This way, when a user switches to a channel, they can join the multicast group for that channel and start receiving the stream immediately if it's already being broadcast.

5. **Adaptive Bitrate Streaming**: Use adaptive bitrate streaming to dynamically adjust the quality of the video stream based on the current network conditions. This ensures that the video starts quickly even if it's at a lower quality, and then improves as more bandwidth becomes available.

6. **Optimize Network Infrastructure**: Ensure that the network infrastructure is optimized for low latency. This includes using fast routing protocols, reducing the number of hops between the source and destination, and ensuring high-quality hardware that can handle the data throughput without bottlenecks.

7. **Quality of Service (QoS)**: Implement QoS on the network to prioritize video streaming traffic over other types of traffic. This helps to ensure that the video packets are transmitted with minimal delay and packet loss.

8. **Client-Side Optimization**: Optimize the client-side hardware and software for quick decoding. This includes using hardware-accelerated decoding when available and ensuring that the decoding software is highly optimized for performance.

By combining these strategies, you can create a system that allows users to switch between channels on a dedicated channel with fixed bandwidth without experiencing more than a one-second delay in video decoding. It's important to note that achieving this level of performance may require careful planning and optimization at every level of the system, from the video source to the end-user's device.
