CPC Class H04N

In accordance with one or more embodiments, aspects of the disclosure provide efficient, effective, and convenient ways of uploading and authenticating content. In particular, a user device may receive validating information from a wireless networking device. The user or client device may record a content item, and may insert a validation tag based on the validating information. The user or client device may then send the content item to the wireless networking device. The wireless networking device may receive the content item at a first location and may determine the validity of the content item based on the validating information. The user device may continually interact with wireless networking devices as it travels to continually upload content items while establishing the validity of the time and location of the content items.

The present technology relates to a receiving device, a reception method, a transmitting device, and a transmission method capable of performing an effective filtering process. There is provided a receiving device including a filtering processing unit that performs a filtering process of a packet by using filtering information arranged in a header of the packet transmitted in a first layer that is a layer upper than an IP layer in layers of a protocol of the IP transmission system in a broadcasting wave of digital broadcasting using an IP transmission system. The present technology, for example, can be applied to a television set.

One embodiment of the present invention sets forth a method for updating content stored in a cache residing at an internet service provider (ISP) location that includes receiving popularity data associated with a first plurality of content assets, where the popularity data indicate the popularity of each content asset in the first plurality of content assets across a user base that spans multiple geographic regions, generating a manifest that includes a second plurality of content assets based on the popularity data and a geographic location associated with the cache, where each content asset included in the manifest is determined to be popular among users proximate to the geographic location or users with preferences similar to users proximate to the geographic location, and transmitting the manifest to the cache, where the cache is configured to update one or more content assets stored in the cache based on the manifest.

A monitoring circuit is provided. The monitoring circuit can be used to monitor signals in a cable network. The monitoring circuit includes first and second stages. The first stage has an input and an output. The input is coupled to an external circuit. The first stage scales a voltage received at its input. The second stage is coupled to the output of the first stage. The second stage has a high input impedance and a low output impedance. The second stage buffers a signal at the output of the first stage to an output of the second stage.
